Abstract

The present research was taken up to study the "Status of insecticide residues and impact of Integrated Pest Management (IPM)". The field studies were conducted to monitor the insecticide residues on food crops (rice, maize, pigeonpea), cotton, vegetables, soil and water and to know the impact of Integrated Pest Management (IPM) in reducing insecticide residues. The laboratory experiments were conducted in Pesticide Residue Laboratory at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, India. Participatory rural appraisal (PRA) was undertaken in Kothapally watershed (IPM village) and Enkepally (non-IPM village). Among the food crops and cotton analysed for presence of insecticide residues (monocrotophos, chlorpyriphos, alpha endosulfan, beta endosulfan and cypermethrin), one rice grain sample (0.5 pg g-') out of 5 samples collected from Kothapally was contaminated and among the soil samples, residues were detected in one soil sample (0.02 pg g'') collected from maize field during 2008 in Enkepally. Only two samples were contaminated -- one rice grain sample (0.008 pg g-I) and one soil sample (0.03 pg g") collected from rice field during 2009 from Enkepally....
