Impacts of newer molecules of insecticides on management of maize stem borers

Manjunath Chouraddi and CP Mallapur

A two year investigation on impacts of newer molecules of insecticides on management of maize stem borers was carried out at Main Agricultural Research Station, Dharwad during kharif and rabi-summer 2010-11 and 2011-12. Among the different newer molecules of insecticides evaluated, single spray of endosulfan 35EC @ 2 ml/l or emamectin benzoate 5SG @ 0.2 g/l or spinosad 45SC @ 0.2 ml/l at 25 DAS as well as whorl application of carbofuran 3G @ 7.5 kg/ha being on par with each other proved superior over untreated control. Maximum net profit was realised in carbofuran and endosulfan treatments (37851.00 and 37197.90 Rs./ha, respectively). The lower net profit was found in imidacloprid and thiomethoxam. The maximum IBC ratio of 28.62 was registered in endosulfan followed by imidacloprid (23.13), carbofuran (17.19), emamectin benzoate (13.44), indoxacarb (11.22), spinosad (7.63) and thiodicarb (6.84) and the lower IBC ratio was recorded in flubendiamide (5.07) and thiomethoxam (6.72).
