OAR@ICRISATField Efficacy of Jatropha Oil, NPV and NSKE against Helicoverpa armigera and Thysanoplusia orichalcea in ChickpeaJJabaauthorA KPillaiauthorMAgnihotriauthorThe investigation was carried out to evaluate bioefficacy of biopesticides such as Jatropha oil, NSKE and NPV in various combinations along with control under chickpea-coriander intercropping ecosystem for three seasons against Helicoverpa armigera. The results revealed that the most effective treatment was T4 (chickpea; Jatropha treated) + coriander (NPV treated) followed by T9 (chickpea; Jatropha treated alone). The pooled mean of lowest damage for 3 years (2011, 2012, and 2013) was in chickpea (Jatropha treated) + coriander (NPV treated) treatments followed by chickpea (Jatropha treated) treatment alone. The mean grain yield of 1292 kg/ha was recorded for T4 treatment in chickpea (Jatropha at 5 mL/L) + coriander (NPV at 0.5 mL/L). The maximum coriander yield of 1008 kg/ha was obtained in T2 treatment, i.e., chickpea (NSKE treated) + coriander (untreated). The present results suggest that Jatropha curcas seed oil either alone or in combination with other biopesticides could be used as botanical insecticide against chickpea pests under any integrated pest management strategy for insect pest control.Pest ManagementHelicoverpaChickpea2017Koul Research FoundationArticle
