Abstract
Ten insecticides were evaluated against majorsucking pests infesting the Bt cotton. Among them five were ofbio-pesticides (Neem oil 1.0 %, NSKE (Neem seed kernel extract) 5.0 %,Azadirachtin 0.0009 %, Verticillium lecanii (Zimmermann) @ 2.5 kg/ha andBeauveria bassiana (Balsamo.) @ 2.5 kg/ha) and five were chemicalpesticides (Acetamiprid 0.004 %, Thiamethoxam 0.01 %, Imidacloprid 0.0089 %,Dinotefuran 0.008 % and Flonicamid 0.02 %) at KVK farm, JAU, Targhadia (Rajkot)during Kharif, 2012-13. The result on the field efficacy of newerinsecticides against major sucking pests of Bt cotton (G Cot Hy 6 BG II)showed that the chemical pesticides caused higher mortality, whilebio-pesticides caused moderate to lower mortality of sucking pests. Among theinsecticidal treatments, flonicamid 0.02 per cent was found more effectiveagainst all major sucking pests, acetamiprid 0.004 per cent against aphid andwhitefly, dinotefuran 0.008 per cent and imidacloprid 0.0089 per cent againstjassid and thiamethoxam 0.01 per cent were found effective against thrips on Btcotton. Among the bio-pesticides, neem oil 1.0 per cent, V. lecanii @ 2.5kg/ha and azadirachtin 0.0009 per cent were found moderate effective againstmajor sucking pests of Bt cotton. In case of toxicity of insecticides onpredators (Coccinellids and Chrysoperla) of sucking pests, all thebio-pesticides were found safer to predators, while chemical pesticides werefound moderate to higher toxic to predators on Bt cotton.
