Abstract
Lady’sfinger Abelmoschus esculentus (L.) Moench is an annual kharif vegetable crop belongs to the family Malvaceae. This crop is cultivated in various parts of tropical and sub-tropical areas of the world. In West Bengal, India it is cultivated in a commercial scale but its pest complex is very high which limit its production. Contribution of whitefly (Bemisia tabaci) and aphid (Aphis gossypii) as sucking pest in this case is of great importance. Three doses of dinotefuron 20 SG (@ 20, 30 and 40 a.i. g /ha) two doses of imidacloprid 70 WG (@ 21 and 24.5 a.i. g /ha) and two doses of fipronil 5% SC (@ 25 and 37.5 a.i. g /ha) were applied to control whitefly and aphid. From overall observation it was revealed that dinotefuron 20 SG @ 40 g a.i./ha, fipronil 5% SC @ 37.5 g a.i./ha and imidacloprod 70 WG @ 24.5 g a.i/ha provided best suppression of whitefly (83.46 %, 82.59 % and 68.94 % white fly population suppression respectively) and aphid (79.02 %, 76.96 % and 70.46 % aphid population suppression respectively). These insecticides may be recommended for farmers use to control sucking pest.
