Bio-efficacy of some newer insecticides against maize stem borer, Chilo partellus (Swinhoe)

Ram Kumar and Tanweer Alam

The present field experiment was conducted to study the bio-efficacy of chlorantraniliprole 20 SC, novaluron 10 EC, flubendiamide 480 SC, deltamethrin 2.8 EC and carbofuran 3G against maize stem borer, Chilo partellus at research farm of Tirhut College of Agriculture, Dholi, Muzaffarpur (Bihar) during Kharif 2016. The minimum and maximum mean per cent infestation (10.60 and 72.60) as well as mean per cent dead heart (3.75 and 23.50) were recorded in chlorantraniliprole 20 SC @ 0.3 ml/l followed by carbofuran 3G @ 7 kg/ha and untreated control, respectively.The highest benefit: cost ratio (13.96:1) was evinced in insecticidal treatment flubendiamide 480 SC @ 0.2 ml/l in sequence with carbofuran 3G @ 7 kg/ha. All the treatments were found significantly superior to untreated control in reducing the maize stem borer infestation and increasing the yield.
