New insecticide proved very effective for management of leaf folder in Paddy

Abstract

An On Farm trial (OFT) was conducted during Kharif 2019-20 and 2020- 21seasons at the farmers’ field to manage the leaf folder, Cnaphalocrocis medinalis through conventional and newer insecticides in rice. Three treatments assessed were T1-Farmer’s practice (Chloropyriphos 20 EC @ 2 ml/l), T2- Monocrotophos 36 WSC @ 1.5 ml/l of water (recommended) and T3 -Flubediamide 480 SC (Fame) @ 0.3 ml/l (New Intervention).The results revealed that use of Flubediamide 480 SC (Fame) @ 0.3 ml/l of water was observed to be superior which resulted in 64.86 per cent reduction in damage to leaves of Paddy and increased the grain yield to an extent of 43.18 per cent over farmers’ practice (Chloropyriphos 20 EC @ 2 ml/l of water) followed by Monocrotophos 36 WSC @ 1.5 ml/l of water In terms of cost benefits Flubediamide 480 SC was proved to be the best. Therefore, the use of Flubediamide 480 SC @ 0.3 ml./lt. of water can be recommended for control of leaf folder in paddy.
