abstract
An experimental trial was conducted during Kharif season of 2016-17 and 2017-18 at the Agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi to manage the leaf folder, Cnaphalocrocis medinalis (Linnaeus) through conventional and newer insecticides in rice. The leaf folder infestation varied from 4.07 to 9.21 per cent during both the year of investigation. Among the various insecticidal field evaluations against leaf folder, flubendiamide 20% WG @ 25 g a.i./ha was found best effective treatment against leaf folder followed by Chlorantraniliprole 18.5% SC @ 30 g a.i./ha, Lamda Cyhalothrin 5% EC @ 20 g a.i./ha, Fipronil 5% SC @ 50 g a.i./ha, Dinotefuran 20% SG @ 40 g a.i./ha, and Thiamethoxam 25% WG @ 25 g a.i./ha respectively during both Kharif season of 2016-17 and 2017-18. The highest mean grain yield 5.10 t/ha during 2016-17 and 4.77 t/ha during 2017-18 was recorded from the plots treated with Flubendiamide 20% WG @ 25 g a.i./ha. While the lowest mean grain yield 3.38 and 3.00 t/ha was harvested from the plots treated with Neem (Azadirachtin 0.15% EC) @ 4 ml/liter during Kharif 2016-17 and 2017-18, respectively.
