Description The 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.
