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.
Consequently, there is excessive use of pesticides to combat the issues. Pesticide usage is
age old and over the decades, there have been various alterations in the pattern of usage
owing to surged awareness.
The current investigation was undertaken to estimate pesticide residues in selected
cereals and pulses grown in the Northern Telangana zone of Andhra Pradesh. The major
districts were Karimnagar, Nizamabad and Adilabad. The crops collected for study were
jowar, maize and soyabean. 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 they applied, yield of crops, the
source of procurement of pesticides, the persons and sources who advised them on
pesticide usage, the storage structures, the processing and cooking practices, implications
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, fiber and carbohydrate. The food samples were analyzed in
two parts, whole and processed. The methods followed were that of Association of
Official Analytical Chemists (AOAC). A multiresidue 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 jowar, maize and soyabean 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 pesticide residues analyzed in jowar, maize and soyabean 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 is due to the fact that cereals and pulses contain lower
moisture, thus not enabling pesticide residues to persist post harvest.
Farmers in the zone experienced many health implications as a consequence of
unsafe handling and application of pesticides. There is an immense lack of awareness
among farmers in the zone with regard to the safe practice in administering pesticides.
Most of the farmers, being small, did not have the affordability to administer the
recommended dosage of pesticides, eventually; the yield among them was lower than that
expected.
