AbstractField experiments were conducted during Kharif 2014, 2015, 2016 to validate IPM module for podborerÂ complex in pigeonpea (Cajanus cajan) and compared with Non IPM (farmersâ€™ practices). The IPM moduleÂ included, pigeonpea intercropped with mungbean at 4:2 ratio in a ridges and furrow system, sprayed neemÂ oil soap 1% concentration at the vegetative stage, installed Helicoverpa pheromone trap @ 12/ha, and twoÂ spray of new insecticide molecule Flubendiamide @ 125ml/ha at the time of 50 per cent flowering stageÂ and Chlorantraniliprole 18.5SC @ 30g ai/ha at 15 days later. The Non IPM practices included, spraying ofÂ Monocrotophos 36 WSC @ 1250ml/ha twice at peak flowering and pod initiation stages. The incidences ofÂ H. armigera eggs (p=0.02), larvae (p=0.003) and per cent damage (p=0.03), Maruca webbings (p=0.04)Â and pod fly infestation (p=001) were low in IPM plot and found statistically significant compared to NonÂ IPM plot. The cumulative yield of pigeonpea for three years was 800kg/ha whereas in Non IPM plot theÂ yield was 320kg/ha. The intercrop besides serving as host for natural enemies it gave an additional incomeÂ and it boosted the net return from IPM plot and average benefit cost over Non IPM practices was 1:3.7.
