Hassan Al Sous Supervisor Dr. Abdel Fattah Hasan Co-Supervisor Dr. Tawfiq Qubbaj Abstract The abundant and intensive use of pesticides has led to many problems worldwide. This descriptive and statistical study is aiming at assessing the knowledge about the use of agricultural pesticide and the safety measures among the farmers in Tulkarm governorate. The sample of 350 farmers, of which 79% are males and 21% are females were subject to a questionnaire from which the response rate was 100%. The results showed that 71.1% of the farmers faced agriculture problems; the most common of which are different crops diseases. 96% of the farmers used pesticides, mainly Confidor. 91.7% stick to the recommended pesticide's dose and 83.1% used to read the information on the pesticide card and follow the instructions. 59.1% of the farmers are not trained for safety measures while 56.9% participants did not attend courses to raise awareness about the dangers of pesticides. Moreover, 62.6% are not trained in integrated pest management, insect and disease identification and prevention, while 72.3% looked for information to develop their knowledge about pesticides. In addition, 72% of the farmers sought to take courses on the safe use of pesticides and 85.1% expressed their interest in knowing xv appropriate solutions to reduce the excessive use of pesticides. The statistical analysis showed that there is significant difference between the geographical location of the farms and the statistical parameters: using pesticides, knowing the amount of applied pesticides, calculate the required dose, adhere to the recommended dose, placing a warning sign on the field, check spray equipment before using, and using mixing tools. There is also significant difference between education level of the farmers and reading the information on the pesticide card, following the instructions, reading the pesticide label, calculate the required dose; conform the expiration date, clean the spray tools, washing hands, and change clothes after spraying. Statistical difference between farmer’s age and use hands to mix without protection is also significant. Between the gender of the farmers and placing a warning sign on the field sprayed with pesticides or where the pesticides are, use PPE when dealing with pesticides and chemicals and use hands to mix without protection there is also a significant difference. The training provided by governmental organization and NGOs to the farmers has also significant difference with placing warning signs on the field or where the pesticides are, using PPE when dealing with pesticides and chemicals, mixing with hands without protection, examination of insect and disease samples before using the pesticide, and adhere to the pre- harvest interval period.

Ancient civilizations used certain materials and applied them to crops to reduce insect infestation or minimize the damage caused by insects to plants. Pesticides are mainly used to increase crop productivity by managing the pest population. The most commonly used pesticide are synthetic chemical products, which are generally used to protect plants from the harmful effects of different pests, such as weeds, pathogens or insects (Mohammed, Bader EL-Din, Sadek, & Mohammed, 2018). The use of pesticides has increased dramatically since the 1960s. In 2007 the French Ministry of Agriculture estimated that 2.4 billion kg of active pesticide compounds were applied worldwide (French Ministry of Agriculture, 2014). The use of pesticides worldwide has increasingly become necessity to produce high quantity and quality of crops to meet global demand. However, the abundant and intensive use of pesticides has led to many problems worldwide: environmental problems, human health concerns, high pesticide residues in food, as well as increased production costs. The environmental effects of pesticides include air and soil pollution, contamination of groundwater and loss of beneficial insects and natural enemies as bees, predators and parasites (which has led to widespread and 2 outbreaks of pest and disease). Despite all these impacts and costs, farmers continue to use pesticides in most countries at an increasing rate, while biological pest control methods are still limited (Wilson & Tisdell, 2001). Several human health effects associated with the use of pesticides have been reported directly, such as; poisoning or irritation of the nose, throat, and skin causing burning, stinging and itching as well as rashes and blisters. Nausea, dizziness and diarrhea are also common, or on long term human diseases development such as; cancer; brain and nervous system damage; congenital disabilities; infertility and related reproductive problems; and damage to the liver, kidneys, lungs and other body organs (Californians for Pesticide Reform, 2020). Humans could be exposed to pesticides during the handling, application, manufacturing and transportation of pesticides as well as when consuming agricultural products contaminated with pesticides. Most pesticides will cause harmful effects if they are ingested accidentally or intentionally or touch the skin for a long time. Pesticide particles may be inhaled with air during spraying application. There is additional risk by the contamination of drinking water or food (World Health Organization, 2000). People who work with pesticides must receive appropriate training on safe handling and application of pesticides (World Health Organization, 2000). According to the accident records issued by the Health and Safety Authority, a farmer is seven times more likely to be seriously harmed at work compared to other workers in any field or business sector. Older 3 people and young children are particularly at higher risk of being injured or killed (Aviva Insurance Limited, 2014). Special precautions must be taken during transport, storage and handling of pesticides. Spray equipment should be cleaned regularly and maintained to prevent leakage. Pesticides will not be hazardous to humans and non-target animal species if appropriate precautions are applied. Personal protective equipment does not prevent the accident but may reduce the harmful effects on human. Therefore, the personal protective equipment must be carefully chosen and tested to see how well it can ensure prevention for those who use it. The unsafe and intensive use of pesticides in agriculture causes a significant risk to human health and environment. Changing the legislation, applying integrated pest management and genetically modified crops in the agricultural production systems are still not efficient in reducing the huge pesticides usage. Especially under the pressure of increasing the demands on agricultural products to meet the population growth, pesticide resistance by pests, economic factors, and the high cost of the alternative environmentally friendly pest controls measures (Abbassy, 2017). 1.2 Research questions This research aims to shed light and deeply investigate and document the current farmer’s knowledge and the most commonly applied practices of handling and using pesticides among Palestinian farmers in Tulkarm 4 governorate as a representative case study. Therefore, the following questions were highlighted and answered by farmers. - What is the level of farmers’ knowledge about pesticide safety applications in Tulkarm governorate? - Are the farmers in Tulkarm governorate applying safety practices (including the adoption of personal protective equipment) when handling pesticides? - What are the farmers implemented practices related to disposal, storage and handling of pesticides? - What are the main obstacles facing farmers in Tulkarm governorate? 1.3 Problem statement The use of pesticides for effective pest control is regulated in a way that the safety limits are not reached when applying according to the good agricultural practices. Environmental contamination, water contamination, air pollution, aquatic habitat as well as human health are endangered due to intensive pesticides application, poor equipment, lack of safety measures, pesticide misuse, poor extension services and the absence of strong policies for pesticide (Amuoh, 2011). Globally, there are many cases of pesticide poisoning, which claimed the lives of many due to the misuse of pesticides, lack of awareness of its seriousness, non-compliance with the recommended dose and safety periods, and non-compliance with safety procedures & practices when 5 dealing with pesticides, including the use of personal protective equipment, disposal of empty containers and quick actions to be taken if being poisoned, all this In light of the weakness of extension services in the field of pesticides (Damalas & Eleftherohorinos, 2011). The presence of pesticides ubiquity makes it imperative to conduct high quality studies of these chemicals. Pesticides have been linked to numerous adverse health outcomes, including cancer, non-malignant respiratory disease, neurological outcomes and developmental issues (French Ministry of Agriculture, 2014). In Palestine, now the study of pesticides and their impact on human health and environment is considered one of the most important and high priority issues, due to its significant role directly influencing the health of Palestinian as well as other living organisms. Tulkarm governorate is considered an important agricultural area in Palestine, and a main producer for vegetables in the local market. Like in many other Palestinian areas, intensive and increasing amounts of pesticides are currently used. With a lack of actual information and scientific research data about pesticide knowledge and safety practices among farmers (Isaac & Hrimat, 2007). This study focused and sheds light on this serious problem, in order to contribute in the protection of farmers and agricultural workers and their families from exposure to the danger of pesticides. Moreover, to reinforce 6 the capabilities of farmers to follow safety and security practices. In addition to protecting agricultural products from pollution, as well as increase the rate of gross domestic product in the Palestinian economy, as a result of increase agricultural production and protecting the agricultural environment from pollution. This study will help policy makers for an in-depth understanding of the current situation on pesticide application and misused application in order to prompt policy-makers to take action. 1.4 Research hypotheses A.

Moreover; this study will: - Compare the level of knowledge on safety measures of pesticide application among farmers in four localities in Tulkarm governorate (Asharaweyah, wadi ashaeer, kafryat and the city and its suburb). - Describe the agricultural situation in Tulkarm governorate. - Assess farmers practices that related to disposal, storage and handling of pesticides; evaluate the protective measures taken by farmers, including the adoption of personal protective equipment, to reduce pesticide exposure. - Identify the obstacles facing farmers in Tulkarm governorate. 1.6 Context of the study 1.6.1 Study area The area of Tulkarm governorate is 246.5 km 2 ; (Palestinian Central Bureau of Statistics, 2017). See Annex 11. Tulkarm is located in the central west of Palestine, in the north of the West Bank and in the eastern part of the coastal plain of Palestine. It is located about 15 km from the Mediterranean coast, also located southwest of Jenin and northwest of Nablus. 120 m above sea level, as well as it is located at geographical latitude 9-532 north 9 of the equator, and geographic longitude 1-535 east of Greenwich. The lands of Tulkarm constitute a separation between the territory of the Palestinian National Authority and the Palestinian territories occupied since 1948 (Tulkarem Municipality, 2018). It is characterized by its location on the boundary between the fertile coastal plain at the west of the city and the mountainous lands that extend to the east of the city. The city's land is distributed between the plain areas, which constitute about 40%, and the mountainous areas, which make up 60% of the total area of Tulkarm. Thus, part of these lands is used for agriculture and grazing, while the other part is used in housing and construction (Tulkarem Municipality, 2018). Tulkarm is characterized by a subtropical climate, the average temperature in winter is 8-16 C o and in summer is 17-30 C o . Humidity is 69.6% in winter, but in summer months it is wet with medium humidity 70.3% (Palestinian Central Bureau of Statistics, 2011). 1.6.2 Agriculture context Tulkarm governorate is famous for its fertile lands and the interest of its people in agriculture; where they depend on agriculture for their livelihoods. Agriculture is considered as one of the most important economic tributaries of the governorate; this sector absorbs many of the labor force, which reduces the prevalence of unemployment among the workers, reflecting an 10 improvement in the economic life cycle among the community (Al-Hewiti, 2017). There are many agricultural crops in Tulkarm, the most famous are:  Olive: The area of land planted with olive trees is about 119711 dunums. Olive trees made up 95% of the cultivated horticulture trees in Tulkarm.  Greenhouses: The area of agricultural land for greenhouses about 8000 dunums.  Citrus: The area of land planted with citrus in Tulkarm Governorate is about 5200 dunums.  Field Crops: includes wheat, barley, lentils, onions, okra and many other crops; the area planted with field crops is about 6400 dunums. (Rainfed constitute 79% and irrigated 21% of the total field land area).  There are agricultural crops that have become widespread recently and the farms are interested in cultivating it, such as: mangoes, avocados, walnuts, java and thyme plantation, which are spread in most of the plains of Tulkarm.  Almonds: such as almond, cherry and apricot trees. (Al-Hewiti, 2017). 11 Reasons for the decline in the area of agricultural land in Tulkarm:  First: The Israeli Occupation Practices on the Land: The crimes of the occupation against the land and the citizen: A. The Israeli occupation erected the separation wall west of Tulkarm. B. The Israeli occupation has established settlements on citizens' lands in Tulkarm.  Second: Despite the abundance of water resources, the Israeli occupation imposed severe restrictions on how to exploit the water and imposed strict control on the artesian wells in the governorate, where monitor and restrict the amount of water pumped for the benefit of the farmer and the Palestinian citizen. The occupation also exploited the water basin located behind the wall on the lands of Tulkarm, in addition to isolating about 5 artesian wells behind the wall.  Third: the urban expansion due to the continuous increase in the population.  Fourth: Establishing economic projects on agricultural lands.  Fifth: Lack of awareness among farmers. (Al-Hewiti, 2017). 12 Chapter Two Theoretical Framework & Literature Review Agricultural products are infected by various pests that destroy the crops. They account to huge loss of crop yields. This result is suffering for both the farmer and the workers. It becomes important for both the farmer and his workers to work together to ensure that crops are not destroyed. It is also important that they both work together to ensure that in the course of work activities workers are not exposed to risks that may cause ill health, injuries and even death. Therefore, the knowledge and understanding of pesticides used in agriculture is an important step in applying good health and safety standards (Department of employment and labour in South Africa, 2016). The application of pesticides affects workers and their families. Since most farm workers and their families live on the farms or near the farms. Environmental problems are also caused by use, overuse or misuse of these pesticides (Department of employment and labour in South Africa, 2016). A. Theoretical framework 2.1 Definition of pesticides Pesticides: Are substances intended to prevent, disease or control in plants or animals’ disease and pests, including vectors of human and animal diseases, unwanted species of plant, or to control the behavior or physiology of pests or crops during production or storage. They include 13 insecticides herbicides, fungicides, acaricides, termiticides and rodenticides and other substances (FAO, 2010). 2.2 Reasons for pesticides intensive use  Rapid Impact: Agricultural pesticides are characterized by rapid action and directly affect pests, even if they have negative effects later, but their direct and rapid impact affects pests and eliminates them as soon as possible if used according to the correct guidelines set for them.  Cheap price: Pesticides are cheap agricultural supplements that farmers resort to periodically, and are available in large quantities due to the proliferation of companies producing them, as well as scientific advances that have been able to integrate these elements and chemical components easily. In addition, biological evolution has discovered many pesticides that work for the same purpose, making competition among producers and making pesticides more affordable than they used to be.  Easy to use: It is known that pesticides are easy to use and do not need someone specializing in agricultural sciences or agricultural engineering to deal with them, and the illiterate farmer can be use it in the quantities set by the agricultural guide, taking into account the appropriate times for spraying.  Accessibility: Pesticides are widely available in various agricultural associations, institutions, agencies and entities specialized in 14 agriculture around the world, whatever their name, which makes their access very large and available to the farmer around the clock, in addition, the ministries of agriculture are keen to provide pesticides to the farmer and to deliver it as much as possible to ensure the production of a good exportable crop and to generate a hard currency for the country. (Menna, 2008). 2.3 Classification of pesticides  The classification based on the basis of use can be as follows: Acaricides, Algicide, Antifeedants, Avicides, Bactericides, Bird repellents, Chemosterillant, Fungicides, Herbicide softeners, Herbicides, Insect attractants, Insect repellents, Insecticides, Mammal repellents, Mating disrupters, Molluscicides, Nematicides, Plant activators, Plant growth regulators, Rodenticides, Synergists, Virucides and Miscellaneous. Acaricides: are the substances that are used to kill mites and ticks, or to disrupt their growth or development. And some of the examples are DDT, dicofol, carbofuran, methiocarb, Propoxur, abamectin, milbemectin, flufenoxuron, chlorpyrifos, oxydemeton methyl, Phorate, Phosalone, fenpyroximate, Fipronil, bifenthrin, cyhalothrin, fluvalinate, permethrin, and chlorfenapyr. Algicide: are the substances that are used to kill or inhibit algae. Some of the examples are copper sulfate, diuron, isoproturon, isoproturon, oxyfluorfen, and simazine. 15 Antifeedants: are the chemicals which prevent an insect or other pest from feeding. Some of the examples are chlordimeforn, fentin and azadirachtin. Avicides: are the chemicals that are used to kill birds. Some of the examples are fenthion, and strychnine. Bactericides: are the compounds that are isolated from or produced by a microorganism (e.g. a bacterium or a fungus), or a related chemical that is produced artificially. Which are used to kill or inhibit bacteria in plants or soil. Some of the examples are copper hydroxide, kasugamycin, streptomycin, and tetracycline. Bird repellents: are the chemicals which act as the bird repellants. Some of the examples are copper oxychloride, diazinon, methiocarb, thiram, and ziram. Chemosterillant: are the chemicals that renders an insect infertile and thus prevents it from reproducing. Some insects that mate only once can be controlled or eradicated by releasing huge numbers of sterilized insects, which act as sterilizing substances for the insects. All of these acts in one of the three ways: (a) They inhibit the production of egg or spam. If it fails then go to the second stages; (b) Cause death of the spam or eggs; (c) If these steps are failed totally then these bring about lethal mutation on the spam or eggs material and severally damage the genetic material and chromatin material of eggs and spam. This produce zygote, but the off springs will totally lose their reproduction ability. (e.g. diflubenzuron). 16 Fungicides: are the chemicals which are used to prevent, cure eradicate the fungi.

(National Institute of Plant Health Management "NIPHM", 2011).  Classification on the basis of the chemistry A large number of group of chemicals are available in the list pesticides but the researcher will be confined to the most common pesticides. a) Insecticides: The insecticides can be classified as Oregano halogen, Organophosphorous, Carbamates, Pyrethroids, Neonicotinoids, Miscellaneous pesticides, Spinosyns (spinosad), neriestoxin (cartap), Fiproles or Phenylpyrazoles (Fipronil), Pyrroles (chlorfenapyr), Quinazolines (fenazaquin), Benzoylureas (diflubenzuron), Antibiotics (abamectin) etc. b) Fungicides: The fungicides are aliphatic nitrogen fungicides (dodine), amide fungicides (carpropamid), acylamino acid fungicides (metalaxyl), anilide fungicides (carboxin), antibiotic fungicides (kasugamycin), methoxyacrylate strobilurin fungicides (azoxystrobin), aromatic fungicides (chlorothalonil), carbamate fungicides or benzimidazole fungicides (carbendazim), conazole fungicides (triazoles) (hexaconazole), copper fungicides, dicarboximide fungicides (famoxadone), dichlorophenyl dicarboximide fungicides (iprodione), dinitrophenol fungicides (dinocap), dithiocarbamate fungicides (mancozeb), dithiolane fungicides 20 (isoprothiolane), morpholine fungicides (tridemorph), Sulphur compounds etc. c) Herbicides: The herbicides are anilide herbicides (flufenacet), chloroacetanilide herbicides (butachlor), pyrimidinyloxybenzoic acid herbicides (bispyribac), benzothiazoleherbicides (methabenzthiazuron), dinitroanilineherbicides (pendimethalin), nitrophenyl ether herbicides (oxyfluorfen), halogenated aliphatic herbicides (dalapon), imidazolinone herbicides (imazethapyr), organophosphorus herbicides (anilofos), phenoxyacetic herbicides (2,4-D), aryloxyphenoxypropionic herbicides (clodinafop), quaternary ammonium herbicides (Paraquat), chlorotriazine herbicides (atrazine), triazolone herbicides (carfentrazone), Urea herbicides (methabenzthiazuron), phenylurea herbicides (isoproturon), sulfonylurea herbicides (chlorimuron). d) Rodenticides: Inorganic Rodenticides: (Zinc Phosphide, Aluminium Phosphide, Magnesium Phosphide) coumarin Rodenticides (organic) (bromadiolone, coumachlor, coumatetralyl). (National Institute of Plant Health Management "NIPHM", 2011) The most common and useful method of classifying pesticide is based on their chemical composition and nature of active ingredients. It is such kind of classification that gives the clue about the efficacy, physical and chemical properties of the respective pesticides. The information on chemical and physical characteristics of pesticides is very useful in determining the mode of application, precautions that need to be taken 21 during application and the application rates. Based on chemical composition, pesticides are classified into four main groups namely; organochlorines, organophosphorus, carbamates and pyrethrin and pyrethroids. The chemical-based classification of pesticides is rather complex. In general, modern pesticides are organic chemicals (Fig. 1) (Kaur, Mavi, & Ragha, 2019). Figure (1): Classification of insecticides. Source: (Kaur, Mavi, & Ragha, 2019). Insecticides Natural Plant based Pyrethrum Azadirachin Mineral oils Synthetic Inorganic Organic Organochlorines DDT BHC Organophosphates Malathion. Temephos. Fenthion. Dichlorvos. Fenitrothion. Pirimiphos methyl. carbamates Propoxur. Bendiocarb. Carbaryl. Pyrethroids Deltamethrin. Cyfluthrin. Bifenthrin. Lambda- cyhalothrin. Permethrin. 22 The chemical-based classification of pesticides is rather complex. In general, modern pesticides are organic chemicals. They include pesticides of both synthetic and plant origin. However, some inorganic compounds are also used as pesticides. Insecticides are important pesticides that can be further classified into several sub-classes (Kaur, Mavi, & Ragha, 2019). 2.4 Advantages of the use of pesticides The advantages of the use of pesticides are: Cost effectiveness "inexpensive", crop protection, control pests, greater yields, effective and rapid, increase food supplies, flexibility in using it, used to kill unwanted plants or weeds which is grown in the field, prevention of problems and disease "controlling the growth of mosquitoes which may cause yellow fever or malaria. It is also used to kill houseflies, cockroaches, lice, poisonous insects to prevent disease caused by it", protect stored food grains and it helps to contribute and enhance human health by controlling the disease spread (Frndzzz, 2019). 2.5 Disadvantages of pesticides The disadvantages of pesticides are: (1) The chemicals used in pesticides are slightly harmful and kills beneficial species of interest and reduces their population. (2) When pesticides are applied to food crops, residues of pesticides may remain on or in food and may be harmful to the body if it is available in higher level. (3) Sometimes pesticides may also eliminate natural enemies of pests such as predators and parasites, leads to increase in population of pests. (4) Promotes genetic resistance. (5) Health risks 23 to both human as well as animals and different types of organisms; "The pesticides used are hazardous and poisonous which may have toxic effect on infants, children and adults if they come in contact with the body". (6) Ground water contamination. (7) Pollutes the environment in general. and (8) Pesticides may accumulate and enter in food chain (Frndzzz, 2019). 2.6 Major types of pesticides which used in Palestine (See annexes 1, 2, 3, 4, 5, 6 and 7). 2.7 Toxicological aspect of pesticides 2.7.1 Toxicity of pesticides Toxicity is the detrimental or adverse effect of any substance or mixture of several substances on the organism. It is divided into:  Acute toxicity: the harmful effect that occurs to the organism after exposure to the pesticide for a short time and once or multiple times during a short period.  Sub-acute toxicity: the harmful effect that occurs to the organism as a result of repeated or persistent exposure to the pesticide for 30 to 90 days.  Chronic toxicity: the harmful effect that occurs to the organism as a result of repeated or persistent exposure to the pesticide longer than half of the life of this organism. 24 In general, all pesticides can be considered toxic substances, and the degree of toxicity of a pesticide varies depending on the dose and sensitivity of the organism, whether human, plant or animal, as well as the ability to cause poisoning and its severity varies according to age, gender, health status, nutrition and pesticides formulation. It is worth mentioning that the toxicity of the chemical is measured by the Lethal Dose Standard, LD50, which is a dose in mg/kg of body weight that kills 50% of the experimental animal population (Agricultural Pesticides Committee, 2017). Signs and symptoms of pesticide toxicity In general: severe weakness and fatigue (El-Nahaal, 2016). Skin: itching, burning sensation, excessive sweating and appearance of spots. Eyes: desire to itch, burning sensation, runny tears, vision becomes difficult or unclear and dilated or narrowed pupils. Digestive system: heartburn, severe salivation, nausea, dizziness, vomiting, abdominal pain and diarrhea. Nervous system: headache, dizziness, discomfort, twitching of muscles, ataxia seizures, loss of consciousness and difficulty in pronunciation. Respiratory system: cough, pain, difficulty of breathing and wheezing. 25 2.7.2 Pesticide residues Pesticide residues: The quantities or concentrations of pesticides that remain on the surface or inside agricultural and food products after using the pesticides. These concentrations vary according to the type of crop and the type of pesticide. Each pesticide has a pre-harvest interval "safety period". Whilst the pre-harvest interval: It is the minimum time duration, between the last time of application of a pesticide on the crop, and the time it can be harvested. That is, after a pesticide is applied to a crop, a specific number of days must pass before the fruit is harvested (Al-Dossary, 2018). Pesticides reach food by spraying crops with pesticides. They can be found in food products or on agricultural crops after harvesting or storage. There are maximum permissible limits in the food and agricultural products of these pesticides, and it varies from one pesticide to another and from a crop or food product to another (Al-Dossary, 2018). 2.8 Common wrong practices when use, storage, transport and disposal of pesticides The most common farmer's wrong practices in Palestine are: Storage of pesticides in nearby the reach of children; Storage of pesticides in an open place without availability of means of prevention and protection; Uncertainty of the pesticide expiry date; Failure of the farmer to read the instructions written on the pesticide packaging or not to abide by them; Mixing several types of pesticides and chemicals with each other to reduce 26 time and cost; Do not wear personal protective equipment; Smoking during spraying; Use a pesticide amount that exceeds the limit; Spray in the opposite direction of the wind; Use of pesticides at inappropriate times; Use of pesticides even if the crop is not infected with diseases; Sometimes when spraying equipment becomes clogged, some farmers open the equipment with their mouths; The farmer does not bathe after using the pesticide; Improper disposal of empty pesticide containers after spraying such as (dumping them in sewers, burying them under the soil, burning them, throwing them on the edges of the field); and Failure to comply with the pre-harvest interval period (Sawalha, 2012). 2.9 Main types of personal protective equipment Figure (2): Personal protective equipment. Personal protective equipment's Eye and face protection Respiratory protection Protective gloves Protective clothes Protective footwear 27 2.10 Pesticide alternatives Pesticide alternatives are considered striking changes in the field of plant protection from pests and human protection from the damage caused by chemical pesticide residues and environmental preservation from chemical pollutants in addition to reducing the costs of pest control and increasing crop production (Kandil, 2000). Advantages of pesticide alternatives, including: a) It is a biological compounds and natural materials that are not harmful to humans, plants, animals and the environment. b) Inexpensive compared to chemical pesticides. c) It begins to be used at levels less than the effect of chemical pesticides and early detection of effect, so spray can be repeated for best results. d) When using biological compounds, the farmer must be confident that the pest will not die immediately, but need the incubation period within it. e) The grace period after spraying and harvesting, is almost non- existent. f) It is the safe and suitable method for culturally different levels in the field of pest control. 28 g) Repeated use leads to an increase in the natural enemies of pests, which reduces the use of chemical pesticides. h) Safety of the product and a guarantee for the source where the food is free from chemicals and preserves the environment from pollution. i) Increase national and individual output as a result of successful control. (Kandil, 2000). Examples of pesticides alternatives: Alternatives to pesticides are available and include methods of cultivation, use of biological pest controls (such as pheromones and microbial pesticides), genetic engineering, and methods of interfering with insect breeding (Miller, 2004). Application of composted yard waste has also been used as a way of controlling pests (Gallaher & McSorley, 1996). These methods are becoming increasingly popular and often are safer than traditional chemical pesticides. Cultivation practices include polyculture (growing multiple types of plants), crop rotation, planting crops in areas where the pests that damage them do not live, timing planting according to when pests will be least problematic, and use of trap crops that attract pests away from the real crop (Miller, 2004). Trap crops have successfully controlled pests in some commercial agricultural systems while reducing pesticide usage; (Shelton & Badenes-Pérez, 2006) however, in many other systems, trap crops can fail to reduce pest densities at a commercial scale, even when the 29 trap crop works in controlled experiments (Holden, Ellner, Lee, Nyrop, & Sanderson, 2012). Release of other organisms that fight the pest is another example of an alternative to pesticide use. These organisms can include natural predators or parasites of the pests. Biological pesticides based on entomopathogenic fungi, bacteria and viruses cause disease in the pest species can also be used (Miller, 2004). Interfering with insects' reproduction can be accomplished by sterilizing males of the target species and releasing them, so that they mate with females but do not produce offspring (Miller, 2004). This technique was first used on the screwworm fly in 1958 and has since been used with the medfly, the tsetse fly and the gypsy moth (Web Archive, 2007). However, this can be a costly, time consuming approach that only works on some types of insects. 2.11 Statistics about pesticides use 2.11.1 International statistics about pesticides use Figure (3) shows the increase of the total global pesticide production over the last decades. Production is measured in million tones here. 30 Figure (3): Total global pesticide production and global pesticide imports, 1940s-2000. Source: (Tilman, Cassman, Matson, Naylor, & Polasky, 2002). Figure (4) shows pesticide use, broken down by product type in the US (As an example). It is measured in tones of active ingredient. Throughout this entire period herbicides were the most commonly used pesticides. Figure (4): Pesticide production in US by type.

Literature review Literature shed the light on the subject of knowledge about pesticide and applying safety practices among farmers. It includes reading and reviewing documentation and information from different sources, such as Palestinian ministry of agriculture, annual reports from the different organizations, several interviews were held with experts in the field of agriculture, previous literature, thesis, reports, published papers, etc. Moreover, the researcher depends on primary sources for collecting data, that was written by the original researchers. These literatures are: o A Guide to pesticide regulation in California: This guide contains information on pesticide laws and regulations, DPR’s organizational structure, an explanation of regulatory and registration processes, a description of local and state enforcement activities, and details on DPR initiatives to protect people and the environment (California Department of Pesticide Regulation "DPR", 2017). o A case study of health risk estimates for pesticide-users of fruits and vegetable farmers in Cameroon: It aimed to assess the health risks of vegetable farmers to pesticide users in Cameroon. The main objective of the study was to investigate the health risk due to pesticide use by small scale independent vegetable farmers and fruits farmers employed under multinational cooperation in Cameroon. The 37 main types of vegetables and fruits produced in Cameroon, the percentage of farmers using chemical pesticides and the frequency and dosage of pesticides use were also investigated. The types, source of pesticides used and method of application of the available pesticides as compared to the recommended standard methods were equally analyzed. Finally, common illnesses in the area which may be related to the use of pesticides were also analyzed. It pointed out that there is a significant proportion of farmers and workers at risk of health problems resulting from the use of pesticides. Majority of the farmers don’t use body covering, eye protection, head covers or nose masks to protect themselves when spraying pesticides. Some farmers even eat, smoke or drink during spraying exposing themselves to hazards. Some farmers use pesticides meant for cocoa, coffee or cotton to spray garden crops and others mix insecticides and fungicides to spray against insects even in the absence of a fungi infection (Amuoh, 2011). o Misuse of pesticides by vegetable farmers in Palestinian territories and recommendations for their proper use: It was conducted to study the misuse of pesticides in Nablus, Tulkarm and Jenin districts. The results have revealed that up to 50% of farmers usually do not read the directions on the labels of pesticide containers. Some of them (20-36%) also dispose of the empty pesticide containers by throwing them in fields or leaving them in corners or near the field hedges. They burn empty fiber and paper containers of pesticides including those of herbicide and they may often not keep enough safe distance from the 38 smoke. Some of the farmers (2-21%) recklessly open containers or pour into the spraying apparatus, as well as spray the pesticides in windy days. Also, 51% of the pesticides available in the Palestinian markets have Hebrew illustration. Furthermore, up to 61% of the farmers ignore the official recommendations of the agricultural extension service. The results showed that most farmers (87-91%) ignore the necessity of wearing the appropriate protective clothing. Furthermore, 80-85% of them do not accurately measure the application rate of pesticides using the proper equipment. Other form of misuse of pesticides is that many farmers (31- 41%) expose themselves to the pesticides, sometimes using their mouths to blow out clogged lines and nozzles. Also, 80% of the farmers whose fields are located beside water canals spray herbicides to control the wild vegetation around them. Above all, most farmers (up to 95%) never precisely observe the safety periods specified between the applications of the pesticides and the harvesting period or reentry time (Sawalha, 2012). o Health risk among pesticide sellers in Bamenda (Cameroon) and peripheral Areas: This study aimed to evaluate the health risk among pesticide sellers as a resulting due to exposure to pesticide Thirty-two questionnaires were administered to 32 pesticide sellers systematically selected, and chi square was used for statistical analysis. From each shop, a respondent was chosen among the workers according to its daily time spent in the workplace. The results showed that there is similarity between sellers in Bamenda and 39 peripheral area; one active ingredient (metalaxyl) and one formulation (beauchamp) sold are not registered; throat irritation, headaches, fatigue, skin irritation, eye irritation, and difficulty in breathing with more cases of nose irritation were symptoms observed; pesticides are stored either in the shops or in warehouses; safety measures generally applied are sitting outside the shop, taking medicated charcoal and the use of protective clothing; 56% have experience less than 5 years. Permanent pesticide sellers are then exposed to chronic intoxication in Bamenda and neighboring zones (Sonchieu, Akono, Ngwamitang, & Ngassoum, 2018). o Assessing knowledge of perceived health risk posed by agricultural pesticides among farmers in Ikenne local government area Ogun state Nigeria: The purpose of this study is to assess level of farmers' awareness about the health risks associated with pesticide use and misuse. The result showed that preventive measures by farmers, including wearing of protective gears while applying pesticides to farmland was common place. It was also found that pesticide disposal practice was poor among farmers, however, farmers practice hand washing, change of clothes and showering after application. Health risk perception was found to be moderate and it was suggested that the reason for the lack of preventive practices and use of protective gear was as a result of low perceived seriousness of the health hazard posed by pesticides. It is hence recommended that farmers should be trained on health hazard of pesticide use and supply of protective gears should be made available at subsidized rate (Gibson, et al., 2017). 40 o Agricultural pesticides and its effects upon health In Gaza governorates: The study dealt with agricultural pesticides and their impact on health in the Gaza governorates. It highlighted on the reality of the pesticides, their quantities and types during the year 2014 and compared to previous years, as well as clarified the sources of pollution of the environment with pesticides, and the reasons for their deployment by identifying farms for reasons of deployment where the researcher distributing (501) the identification of the composed of farmers from several areas in which spotted the problems and consequences of the excessive use of agricultural pesticides and its dangers on the farm's health and the health of citizens and the statement of the effect of some of the pesticides used in the provinces of Gaza, as the study on the impact of hormones plant, as well as the impact of pesticides on the environment of soil, water and air and the enemies of vitality and Wildlife and its impact on the food, and also study examined pesticide residues in breast milk and blood plasma arose researcher to monitor pesticide residues them, as well as agricultural products (exported and imported and domestic) (Alatawna, 2014). o Farmers' knowledge, practices and injuries associated with pesticide exposure in rural farming villages in Tanzania: The objective of this study was to describe the exposure of farmers to pesticides, knowledge about pesticide risks, the experience of previous poisoning, and hazardous practices that may lead to acute poisoning. 41 Insecure practices for pesticide handling was assessed through pesticide storage monitoring, PPE conditions and through self-reports for pesticide disposal and calibration equipment. The study found a high potential for exposure to pesticides in the selected community in Tanzania's rural areas, a high percentage of acute self-reported pesticide poisoning and poor registration in hospital records (Lekei, Ngowi, & London, 2014). o Farmer’s knowledge, attitudes and practices, and their exposure to pesticide residues after application on the vegetable and fruit crops in North of Delta, Egypt: The aim of this study is to assess farmers' awareness of the safe use of pesticides and field spraying practices that may potentially expose them to chemical hazards. The study was carried out among smallholder farmers of intensive vegetable and fruit production zones at northern delta, Egypt. Data was based on a random sample of 86 farmers using structured interviews and direct field observations. The obtained results showed that in spite of the farmers have good knowledge about the potential negative effects of pesticides on the human and for somewhat on the environment, lack of their following safety measures was dominant (Abbassy, 2017). o Pesticide Knowledge and Safety Practices among Farm Workers in Kuwait: Results of a Survey: The aim of this study was to assess the levels of knowledge, attitude and practices of Kuwaiti farmers regarding the safe use of pesticides. A total of 42 250 farmers participated in this study through in-depth interviews and observations on-farm. The majority of the farmers acknowledged that pesticides were harmful to their health (71%) and the environment (65%). However, farmers’ level of knowledge of pesticide safety is insufficient. Over 70% of the farmers did not read or follow pesticide label instructions, and 58% did not use any personal protective equipment (PPE) when handling pesticides (Jallow, Awadh , Albaho, Devi, & Thomas, 2017). 43 Chapter Three Methodology 3.1 Research design This research is followed a descriptive, non-experimental research design. Whereas a descriptive research aims to accurately and systematically describe a population, situation or phenomenon. It can answer what, when, where, and how questions, but not why questions. To determine cause and effect, experimental research is required. A descriptive research design can use a wide variety of quantitative and qualitative methods to investigate one or more variables. Unlike in experimental research, the researcher does not control or manipulate any of the variables, but only observes and measures them (McCombes, 2019). 3.2 Inclusion & Exclusion criteria 3.2.1 Inclusion criteria  All farmers, who are living in Tulkarm governorate, and available at the study period.  Small or big size farm owner.  The farmers who were interviewed during the pilot study. 44 3.2.2 Exclusion criteria  Farmers who are none available at the time of data collection.  Farmers who refuse participation. 3.3 Study population The target population of this study is all farmers in Tulkarm governorate. The total number of farmers in Tulkarm governorate was 3900 according to the Palestinian Ministry of Agriculture. 3.4 Study period The study was performed from March 2019 to March 2020. 3.5 Sampling technique and sample size The sample size was 350 farmers from Tulkarm governorate. The number of samples was measured by Sample Size Calculator (see annex 8). Which helps to determine the ideal sample size. Sampling was simple random method; in which each individual was chosen randomly and entirely by chance, such that each individual had the same probability of being chosen at any stage during the sampling process. 3.6 Study tool A questionnaire was distributed to farmers who illegible to the study criteria. The questionnaire included questions about (level of knowledge in 45 pesticide, applied safety practices when dealing with pesticide, practices regarding, handling, disposal and storage of pesticides, and the obstacles faced by farmers) (see annex 9). 3.7 Response rate The number of respondents was 350 (represents 100%). 3.8 Construction of questionnaire A questionnaire was designed to assess the levels of knowledge of the safe use of pesticides and safety practices applied by farmers in Tulkarem governorate. It was reviewed and validated by the supervisors, designed in English and translated into Arabic, the national language understood by farmers. The questionnaire included closed and open-ended questions and was pre-tested by randomly interviewing 135 farmers included in this study. The closed questions were in a multiple-choice format. Farmers had to select only the appropriate answer or answers that they thought will describe their opinion on a particular issue. The questionnaire contained eight main sections. Each section was designed to collect information on a particular issue related to the safe use of pesticides as the following: - The 1 st part included items related to the social characteristics of the farmer. - The 2 nd part included items related to the characteristics of agricultural land. 46 - The 3 rd part included items related to farmer knowledge of pesticide use. - The 4 th part included items related to farmers knowledge of health and safety measures during the use of pesticides. - The 5 th part included items related to the health effects of pesticide use. - The 6 th part included items related to the storage of pesticides. - The 7 th part included items related to the environmental effects of pesticide use. - The 8 th part included items related to obstacles and suggestions. 3.9 Validity of questionnaire 3.9.1 Face validity It is designed to make people more responsive to the questionnaire; the researcher checked the face validity twice. The first check was through 8 expert persons from An-Najah National University and the Ministry of Agriculture who gave their suggestions and judgment about the questionnaire’s adequacy. The second check was during the pilot study, as the included participants were asked about the structure of the questions, its shape, and typo-free. 47 3.9.2 Content validity It was done before data collection. The questionnaire was sent to 7 experts (annex 10) with a covering letter and the instructions about the study, overall aim, objective, field of the study, and other relevant information. The experts were asked to evaluate and revise the questionnaire’s relevance to the study, clarity, and completeness of each section. Feedback was obtained from experts, and modification was done with the researcher supervisors, where their opinions were considered. The questionnaire was translated to Arabic by the researcher and assessed by an Arabic language expert who gave advice and modifications. 3.10 Pre-test of the questionnaire A Pre-study was conducted on 10% of the sample. 35 participants were included as a pilot study group to ensure the questions are clear and avoid questions length & ambiguity. The pilot study group included farmers form different age groups, gender, educational levels, and residency status. All of them were provided with a clear explanation about the study and its objectives before application, to ask them about difficulties and their opinion of the questionnaire. The results of the pilot study were very helpful in modifying the tools. 3.11 Reliability of questionnaire The Reliability of an instrument is the degree of consistency with which it measures the attribute it is supposed to measure. The reliability of an 48 instrument was done by computing Cronbach’s Alpha coefficient. Whereas Cronbach's alpha is the most common measure of reliability (for most purposes, reliability coefficient above 0.7 is considered satisfactory); it was done using SPSS program. The results ranged from 0.822 and 0.910 and the general reliability for all items is equal to 0.855. This range is considered very well, and indicated high reliability of the questionnaire. 3.12 Data collection Data was collected by the researcher through face-to-face farmers’ interview. The interview was started by giving the farmers complete instructions and explanations about the study and its objectives and the importance of providing reliable answers. The interview was done at an appropriate time, taking all ethical considerations. 3.13 Data entry and analysis Excel software program was used for data entry. The data were analyzed using the Statistical Package for Social Sciences (SPSS) programs, with the assistance of a statistician. Frequency tables for the study variable were conducted. 3.14 Ethical consideration Approval letters were taken from An-Najah National University, and the Palestinian Ministry of Agriculture; as well as consent was taken from each participated farmer. 49 An explanatory letter was attached to the questionnaire and provided to the participants, which include the study title, objectives and other information needed to make clarification to the participants. The researcher gave the participants the right to participate or not, and ensure confidentiality (anonymity was maintained into the explanatory letter). Respect all personal beliefs. Moreover, choose the right place to collect information according to farmers’ convenience. 3.15 Limitation of the study The researcher faced some challenges during the time course of data collection and questionnaire preparation, which illustrated as; - Lack of information, insufficient and inappropriate data registry. - Lack of previous studies in the research area. - Time limitations. - Lack of financial funding for the study. The prevailing political situation in the area which limited movements and makes difficulties in research studies due to barriers and check-points. And, difficulty of transportation. 50 Chapter Four Results and discussions This chapter points out the results and discussion of the study, including descriptive analysis that presents the socio-demographic data of the study and the answers to the questions of the study.
