Description |
The use of pesticides has become inevitable in agriculture due to diverse reasons. Farmers are compelled to administer pesticides owing to the affluence of pests, eventually affecting the yield and quality of crops grown. This certainly affects the economy of the country. Pesticide usage is age old and over the decades, there have been various alterations in the pattern of usage owing to surged awareness. Therefore, the current investigation was undertaken to estimate pesticide residues in selected cereals and pulses grown in the Godavari zone (East and West Godavari districts) of Andhra Pradesh. The crops collected for study was rice, maize, black gram and Green gram. The recommended package of practices and the farmers’ pattern of pesticide usage were studied using a structured questionnaire. Information was obtained on the pesticides used in the zone, the dosage applied, yield of crops, the persons and sources who advised them on pesticide usage, the storage structures, the pre and post processing practices, implications of pesticides on health of farmers and the annual expenditure on pesticides. Thirty farmers were selected randomly for the study. Besides, the study included the estimation of proximate composition of the selected food grains from the zone. The proximate analyzed were moisture, protein, fat, ash, fibre and carbohydrate. The samples were analyzed in whole and processed forms. A multi residue determination procedure was used to analyze pesticides by the gas chromatogram. The experimental aspect of the study was undertaken at the Quality Control laboratory, A.N.G.R.A.U. The pesticides analyzed in rice, maize, black gram and green gram were monocrotophos, acephate, chloropyrifos, quinalphos, carbofuran and endosulfan. Endosulfan is the exceptional pesticide that belongs to the organochlrine group of pesticides with the rest belonging to orgniphosphate group. The values of the proximates i.e., moisture, protein, fat, fibre, ash and carbohydrates were tabulated in the results and discussion. The nutritional quality of the selected food grains were nearly equal to the proximate content reported by Gopalan et al. (2004). Statistically significant difference at 5% level was observed with regard to the nutrients moisture, fibre, fat (except for maize), protein (except for maize and green gram) and carbohydrate. And statistically significant difference at 5% level was not observed in ash. The pesticide residues analyzed in selected whole and processed food grains were below the detection limits (BDL). Residues of pesticides are relatively less likely to persist in cereals and pulses than in vegetables or fruits. The amounts of residues thus, detected are low to negligible. This perhaps was due to the fact that cereals and pulses contained low moisture content, thus not enabling pesticide residues to persist. Farmers in the zone experienced many health implications as a consequence of unsafe handling and application of pesticides, due to lack of knowledge .There is a need to educate the farmers about ill health effects of not taking proper precautions during the application of pesticides and to avoid the minor and major health aliments to the farmers. |
