Field-efficacy of novel-insecticides against fall armyworm, Spodoptera frugiperda in maize

Abstract

The present investigation was conducted during kharif 2022 in Randomized block design with three replications at the experimental farm of Baba Raghav Das Post Graduate College, Deoria, Uttar Pradesh, India. The evaluation of efficacy of newer molecules of insecticides (i.e., Lambda cyhalothrin 7.5% SC @ 2 ml l-1, Dr neem 5% @ 5 ml l-1, Chlorantraniliprole 18.5% SC @ 0.20 ml l-1, Spinetoram 11.7 % SC @ 0.25 ml l-1, Fipronil 0.3% GR @ 100 g 2 kg-1 sand, Carbofuran 3% CG @ 200 g 2 kg-1 sand) was performed over the Vivek maize hybrid-53. Per cent leaf damage and per cent plant damages were observed after application of insecticides. The results on overall performance of insecticides revealed that Chlorantraniliprole 18.5% SC @ 0.20 ml l-1 and Fipronil 0.3% GR @ 100 g 2 kg-1 sand were found superior against leaf and plant damages of maize, respectively. Also, all the insecticides including one neem-based botanical (Dr. Neem) were significantly effective over control check.
