It benefits us by killing unwanted organisms called pests or by controlling their attack. Although their potentiality of affecting life and environment adversely are well established and accepted facts. Therefore, the persons who are directly exposed to these toxic chemicals as a part of their occupation may be at risk. Farmers and farm labourers constitute a major segment among the workers who are mostly exposed to pesticides in the third world countries. In most of the countries pesticides are subjected to pre-market assessment for determine their efficacy and safety. Food residue data and toxicity test results on animals are scrutinized but scant attention has been paid to the user or bystander (people inadvertently exposed to pesticides, used by others). The long-term, unintentional, occupational exposure to pesticide of the farming community is of concern by the development practitioners and environmentalists as the estimates of unintentional death worldwide is however much higher than the intentional accidental poisoning. The majority of these fatalities occur in tropical developing countries despite the fact that they account for only a small proportion (about 25%) of global pesticide use (Rainbird et al., 1994). And some studies indicated high correlation between chronic exposure of pesticide and adverse health effect on workers (Conway and Pretty, 1991). The results of the health assessments showed that farmers and agricultural workers faced chronic health effects on eye, skin, heart, nervous system, kidney etc. due to prolonged exposures. One or more of these symptoms lead to lower productivity due to farmers’ absence from work during treatment and recuperation or to impaired capacity to do a fool load of work. The value of crop lost to pest is invariably lower than the cost of treating pesticide-caused diseases. In this context the study of pesticide handling behaviour of the farmers has some relevance to explore the effect of pesticide exposures on them in the context of adhering safety norms and to throw some insights related to feasible interventions for minimizing the adverse effect on them. Methodology: Haringhata block of Nadia district, West Bengal was chosen purposively for the study due to its high cropping intensity, vast acreage under vegetable and long tradition of using different pesticides over the past years. Multistage proportionate random sampling was adopted for selecting four villages. Total enumeration technique was employed for selecting the respondents who qualify as vegetable growers in the chosen villages. A structured schedule was prepared based on the objectives of the study. The data was collected through personal interview method after pre-testing the schedule in the year 2003-2004. Finally, 400 vegetable growers were retained as respondent after three repeated visits. Two specific case studies were done where severe health problems were observed. Results and discussion: The obtained results have been analyzed and presented in a tabular manner for better understanding of the health problems, related pesticides, extent of following safety norms and sources of information for purchasing and handling pesticides. A brief presentation of the case studies is furnished in oral narrative form.

At the most, 53.25 per cent of the respondents reported that they had the problem of skin irritation or itching after application of pesticides. The problem occupied 1st rank when the problems were arranged in rank-wise. At the lowest 6 per cent of respondents had drowsing problem and it occupied 7th rank among the other problems. About one –fifth of respondents (21.25%) in the study area had the headache problem during and after application of pesticides and it possessed 3rd rank. About one –fourth of respondents (25.25%) replied that they had the problem of weakness and also responded that it was a common problem to all after applying most of the pesticides and it obtained 2nd rank. Eye irritation was reported by 17.25% of respondents and it occupied 4th rank accordingly. Breathing problem was reported by 14.75 per cent of respondents, which occupied 5th rank among the other problems reported by them. Only 8.75 per cent of respondents reported that they had the problem of vomiting that occupied 6th rank. Most of the respondents in the study area opined that application of pesticides after eating reduced the vomiting problem up to a certain level.

Malathion was an eco-friendly pesticides though it caused breathing problem and headache and it was reported by 48 per cent of respondents 60 About half of respondents (43.33%) reported that Furadon caused Itching and vomiting problem to them.Thimet also had the similar effect like Furadon, it was reported by 26% of respondents. Only 8.75%of respondents had the problem of Drowsing and eye splashes those were caused by Vapona. One- third of respondents (34%) reported that they had the similar effect due to application of Thiodon. Folidol dust caused skin irritation and breathing problems and it was reported by 8.75 per cent of respondents of study area. Metacid, a major insecticide in the study area also causes breathing problem along with weakening of the applicators as reported by 15.25 percent of the respondent. The pesticide, Ekalux promotes weakness and drowsiness among 4 per cent of the respondent according to their perception.

Wash the body part with soap in case of accidental contact with pesticides. Abstain from taking food or smoking during pesticide application. Check the spraying implement before pesticide application. Avoid blowing the clogged nozzle of the sprayer before pesticide application. Abstain from pesticide application at the time of high wind. Do not apply pesticide against the wind direction. Do not leave the field keeping the pesticide container behind. Do not use the container of the pesticide for other causes. Do not wash the containers like bottle, mug, bouquets, and sprayer in the pond.

Twenty-three statements were selected from the literature of plant protection and expert views. There were four columns (Always, sometimes, seldom, never) under the heading of ‘What you do’ in respect of each statement. The respondents replied satisfactorily and the responses had logical basis. Proper diagnosis, choice of pesticide and determination of dose Twenty one percent respondents in the present study, first identified the insect- pests and diseases and thought about their nature of damage or level of damage and 4 percent of respondents some times did it whereas thirty percent of respondent seldom did it and remaining 45 per cent never did it. More than half of the respondents (60%) reported that they did not contact with agricultural staff (ADO, KPS) in their locality, whereas 20 percent of the respondents replied that they seldom kept contact with the agricultural staff and 15 percent of the respondents sometimes did it. Only 5 percent of the respondents always did it when they were unable to tackle the problems due to pest infestation. Most of the respondents had lack of faith on Government recommendations but the educated and innovative farmers applied pesticide on the basis of recommendation. Majority of the respondents (60 %) reported that they sometimes used pesticides on the basis of recommendation and 20 percent of respondents replied that they always used recommended pesticides whereas 15 percent of the respondents seldom did it and remaining 5 percent of the respondents never did it. Most of the farmers had a mis -conception that more amounts of pesticides beyond its recommendation per unit of area or per unit of water will give better results. When the recommended dose of pesticides did not give desired result then they motivated to another option. Actually, it expressed their mental puzzling condition. “If there is lot of recommended pesticides for a particular insect- pest or disease then you select that pesticide which is safe and having less hazardous effect on environment”, in the response of this statement, 60 percent of the respondents told that they never did it, 20 percent of the respondents seldom did it and 10 percent of the respondents always did it whereas another 10 percent sometimes did it. Farmers general view in this respect was that, they were mainly concerned about the effectiveness of the pesticides, either these were hampering environment or not they were not bothered, because they were business minded. Application of pesticides after careful reading of label of bottle or packet of pesticide More than half of the respondents (60%) reported that, they always applied pesticides after careful reading of label of bottle or packet whereas 35 percent of the respondents told that they were applied pesticides whatever the retailers prescribed at the time of purchasing. Only five percent of them sometimes followed the prescription of the label of bottle or packet. Opening the packets or bottles by using knife or by mouth Almost all the respondents (96%) replied that they used special knife for opening the bottles or packets of pesticides whereas remaining 4 percent of the respondents replied that they sometimes opened the bottles by mouth. Keep the bottles, small containers and packets of pesticides in a particular place, which is out of touch of children. All the respondents in the present investigation reported that they keep the bottles, small containers and packets of pesticides in safety place which is out of touch of the children. Keep the products in certain distance from the food materials Almost all the respondents (95%) replied that they kept the bottles; small containers and packets of pesticides in a certain distance from the food materials whereas only remaining 5 percent of the respondents told that they sometimes kept, it ignoring the restriction. Application of pesticides without proper clothing Twenty five percent of the respondents reported that they had applied pesticides without proper clothing and 30 percent replied they sometimes did it where as 40 percent of the respondents reported that they seldom did it. Only 5 percent of the respondents told that they were habituated with the application of pesticides with out wearing any shirt. During application of pesticides, use thick napkin to cover mouth and body Twenty percent respondents answered that they always used thick napkin to cover mouth and body during application of pesticides whereas 35 percent of the respondents sometimes did it and 25 percent of the respondents seldom did it. Only 20 percent respondents told they never use any napkin to cover the mouth during application of pesticide. After application of pesticides to wash hands and legs by soap Maximum number of the respondents (80%) replied that they always used soap to wash hands and legs after application of pesticides on vegetable crops whereas 14 percent respondents sometimes did it and only 6 percent of the respondents told that they seldom did it. The pesticide penetrated in the body of pesticide applier, which created various health problems. So they did it to remove the hazardous effect and offensive odor from their body. Sticking together of pesticides with any part of body requires washing by soap Maximum number of the respondents (75%) told that they always washed the body part by soap when a pinch of pesticides solution was touched the body whereas rest 25 percent told that they sometimes did it. Taking food or smoking during application of pesticides Almost all the respondents (95%) reported that they did not take any food materials or smoke during application of pesticides and remaining 5 percent told that they sometimes smoked during application of pesticides. All the respondents either literate or illiterate knew it, that pesticides were poisonous substances though 5 percent of them were the slave of their smoking habit. To check the implements before application of pesticides To check the implements before application or spraying of chemicals was very essential for smooth running of function. Maximum number of respondents (90%) replied that they always checked the plant protection equipments before spraying the chemicals whereas 5 percent of respondents some times did it and remaining 5 percent of respondents seldom did it. Clean the nozzle of sprayer machine through whiff Sixty five percent of the respondents answered that they never cleaned the sprayer machine through whiff because there was possibility of contact of pesticides with mouth, which leaded health problem. In this study 25 percent of the total respondents told that they seldom did it whereas only 10 percent vegetable growers sometimes did it. No application of pesticides during high velocity wind blowing Half of the respondents (50%) in the present study reported that they did not apply pesticides during high velocity wind blowing due to much loss of pesticides, created health hazards and ineffectiveness of pesticides. Whereas 30 percent of the total respondents seldom applied pesticides during wind blowing and remaining 20 percent replied they sometimes applied pesticides according to their urgency of application. No application of pesticides against the direction of wind blowing More than half of the respondents (53%) did not applied pesticides against the direction of wind blowing whereas 27 percent of the respondents sometimes did it and reaming 20 percent of them seldom applied pesticides against the direction of wind blowing. At the most 53 percent respondents were comparatively more health consciousness over profit consciousness. Those applied pesticides against the wind direction, they were very much profit oriented. Do not move anywhere leaving the pesticides in field Thirty eight percent of respondents reported that they did not move anywhere leaving the pesticides in the field during application of pesticides and 25 percent of them told that they sometimes did it. Thirty percent of the respondents told that they seldom moved anywhere during application of pesticide whereas 7 percent respondents always moved anywhere without any hesitation. Due to several causes they moved sometimes, the identified causes were – to cut the bunds for irrigation, to bring the spraying water, and urgent work in house etc. No use of empty packets, bottles of pesticides for other purpose Twenty one percent of the respondents (21%) reported that they did not use the empty bottles or packets of pesticides and more than fifty percent of the respondents (57%) seldom used it and remaining 22 percent of the respondents sometimes used the empty bottles of pesticides. Do not wash the empty tin, bucket, mug and bottle of pesticides in the pond Eighty percent of the respondents reported that, they did not wash empty tin, bucket, mug and bottle of pesticides in the pond whereas 10 percent of the respondents sometimes did it and remaining 10 percent of the respondents seldom washed the empty tin, bucket, mug and bottle of pesticides in the pond which was not used for domestic purpose. Harvest the vegetable after knowing the stability of pesticides in that vegetable after application of pesticides Majority of the respondents (45%) reported that they seldom collected the vegetable after knowing the stability of pesticides in that vegetable crop after application of pesticides, whereas 10 percent of the respondents told that they always did it and 30 percent of the respondents sometimes did it. Only fifteen percent (15 %) of the respondents never did it due to their profit mindedness. Application of pesticides during flowering Exactly, half of the respondents (50%) reported that they sometimes applied pesticides during flowering whereas 30 percent of the respondents seldom did it. Only 10 percent of the respondents did not apply any pesticides during flowering but another 10 percent of them reported that they used pesticides without considering the flowering period. Actually, a pesticide is not applied during flowering because of its ill effect on flowering and fruit setting. Application of pesticides during noon period of the day when very hot and bright sunlight prevailed Most of the respondents (95%) in the study area reported that they did not apply pesticides during noon period of the day when very hot and bright sunlight prevailed whereas only 5 percent of the respondents seldom applied pesticides during noon hours of the day under compulsion. Naturally farmers did not apply pesticides during noon period because of desiccating effect, irritating weather condition, and lower incidence of insect- pests (hide in bushes and soil or cracks of the soil).

The respondentswere asked about most commonly used pesticides (30) and the respondents responsed according to their level best perception .At the most 97 percent of respondents collected information about Kelthane from the dealers of the study area whereas only 7 percent of respondents gathered information about Metasystox from dealers. More than half of respondents (55%) had the experience about the Thiodan and the rest (10%) collected the information from Neighbours. Seventy percent of respondents got the information about Endocel from Dealers and 20 percent got it from the Neighbour whereas 10 percent got it from the Company personnel. At the most 60 percent collected the information about Sevin from the Dealers and 25 percent took their own decision. Only 15 percent of them accepted the information from their Neighbours. Exactly, 50 percent of respondents received the information about Furadon from the pesticide Dealers and 12 percent of them from their Neighbours. Remaining 38 percent of growers had the idea about application procedures of Furadon. In case of Diafuran, 80 percent of respondents got the message from the retailers during the purchasing period whereas 5 percent of them used the pesticide from their past experience and remaining 15 percent of growers collected the information from their Neighbours. Box 1 Case 1: Anwar Mondal, Mollabelia, Haringhata block, Nadia, West Bengal. ‘I have been spraying pesticide regularly for five years on contractual basis. Recently I have severe gastro intestinal tract problems possibly caused by my earlier exposure to pesticides for the last few years’. Case 2: Babla Monadal, Nalkudia, Haringhata block, Nadia.’ I served as permanent labour in rich farmer’s house for last 12 years and assigned as applicator of pesticides for my skills. Recently I am suffering from kidney ailment and I presume my exposure to pesticides may have some connection to my ill state of health’. Conclusion and recommendation: A high portion of pesticide intoxication related health hazards due to pesticide exposure caused by unsafe attitudes and dangerous personal work habits, lack of knowledge, lack of proper personal protective and spraying equipments, loading methods, the technology available is often unsuitable to small and marginal farmers of the tropical countries. Agricultural extension mostly promoted by the untrained retailers or his peer group members is not oriented to need-based information for safe handling of these dangerous chemicals, first aid etc. The recommendations emerged out from the study clearly spell out for a holistic approach to combat the grim situation. They belong to three basic domains of interventions, namely extension, research and policy. Extension Training of stakeholders in safety precautions, recognition and management of pesticide related ill health as a matter of urgency. Sensitization of policy makers, teachers and students. Research Epidemiological studies for investigating pesticide induced ill health. Development for appropriate and affordable personal protection equipment. Biological monitoring Policy Incorporation in school syllabus. Plant protection equipment subsidization. Policy for appropriate product packaging and use of protective equipments and apparels.
