ENUMERATION OF ORGANCHLORINE, ORGANOPHOSPHATE AND SYNTHETIC PYRETHROIDS IN BEANS GROWN IN FIVE DISTRICTS OF KARNATAKAAbstract
Pesticide residues in food and crops are a direct result of application of pesticides to crops growing in the field. Large quantities of pesticides are being used to control various pests, which normally infest the economically important plants. Beans- grown across the country and provides an important source of income for the small and marginal farmers. Bean growing in five districts of Karnataka viz., Bangalore urban, Bangalore rural, Ramanagara, Tumkur, Chikkaballapura and Kolar are the prime areas in the production of vegetables identified for the detection of pesticide residues. Bean samples spiked at 0.01, 0.5 and 1.0mg/kg and average recovery rate ranged from 77.0 to 95.4% & the average RSDs from 1.2% to 6.1%. Presence of Cyfluthrin- β, cyhalothrin-λ, cypermethrin, deltamethrin and fenvalerate Acephate, chlorphyriphos, dichlorvos, monocrotophos showed values Below Detection Level (BDL). 5% 0f the samples collected from the five districts showed mean phorate concentration (0.035 mg/kg) exceeding the MRL value of 0.05mg/kg in Bangalore urban district.
