Improving farmer’s knowledge on indigenous practice of spraying pesticides in grape garden

Abstract

Usually grape orchards pruning will take place in the month of April. For this to grow well without affecting any insects, during rainy season that is, from November onwards pesticide was sprayed twice a week. And also before harvesting grape bunches are dipped into the pesticide solution, which might adversely affect the health of the sprayer. Bringing change in entire dress (Protective clothing) is a big task both in monetary and motivation in spite of adverse remarks in wellbeing. To overcome this, present study was conducted to analyze the presence of pesticide residue through Gas Chromatographic analysis on the 5 per cent starch treated Polyester Cotton 67:33, 50:50 blends, which is most commonly used material for farm workers shirting. The test was conducted against the pesticide Rogar, a dimethoate, an insecticide which is most commonly used in grape gardens, 2% concentration of which was sprayed on test sample. Along the test samples were analyzed for the presence of pesticide residue with SHIMADZU-GC-17A type of Gas Chromatography. From the analysis, it was observed that 67:33 poly-cotton samples absorb fewer amounts of pesticide residues than 50:50 poly-cotton samples. Even though 5 per cent starch treated samples showed greater absorbency than 10 per cent starch treated sample, 5 per cent starch treated samples were selected to observe residue levels after washing with 5 per cent sodium Chloride water and 2 per cent heavy duty detergent at 1200F and 1400F. Among the washings samples with 2 per cent detergent was found to be having less residues than 5 per cent sodium Chloride washed samples, where under 1400F removal of residue levels were greater than 1200F. In a view of economic conditions of the farmers, 5 per cent starch treated clothing while spraying can be suggested with 5 per cent sodium Chloride (salt) washing after pesticide spraying.
