Bioefficacy and dissipation of ?-cyfluthrin against white fly Bemisia tabaci Genn.) in okra (Abelomoschus esculentus L.)
Article Main
Abstract
A field experiment was conducted to evaluate the efficacy of different insecticides viz., bifenthrin, flubendiamide, fipronil, quinalphos, pronofos and ?-cyfluthrin against white fly (Bemisia tabaci) of okra (Abelomoschus esculentus) by spraying twice. Among the insecticides evaluated, ? cyfluthrin at 18.75 g a.iha-1 was found to be the effective by registering 57.00 and 54.21 per cent reduction of whitefly (B. abaci) during first and second sprays, respectively. Further ?-cyfluthrin at 18.75 g a. i ha-1 was subjected to dissipation studies by collecting okra (A. esculentus) fruit samples at interval of zero, one, three, five, seven, 10 and 15 days after last spray. Results of the dissipation studies showed that the initial deposits of ?-cyfluthrin (18.75 g a.iha-1) in okra (A. esculentus) fruit sample was registered to be 0.11 mg kg-1 and dissipated to below detectable level (BDL) within five days after spray.
