Abstract

During Khariff-2017 seven different IPM modules were evaluated against green semilooper, Thysanoplusia orichalcea Fab. and capitulum borer, Helicoverpa armigera Hub. infesting sunflower. of which spinosad based module (M5) (Seed treatment with imidacloprid 70 WS (5 g/kg) + metalaxyl 35 SD (5 g/kg) + hand picking & destruction of gregarious early instar larvae of defoliators (Spodoptera litura Fab. and Spilarctia obliqua Walker) + 2 sprays of spinosad (50 and 70 DAS) found superior against major defoliator T. orichalcea Fab. at 3, 5 and 10 days after second spray and capitulum borer, H. armigera Hub. at 3, 5 and 10 days after first spray, followed by IPM module (UAS-B) (Seed treatment with imidacloprid 70 WS (5 g/kg) + two sprays of 5 % NSKE and HaNPV (50 and 70 DAS). The present findings also revealed that spinosad based module and NSKE based modules were potential candidates for the suppression of green semilooper and capitulum borer among the different IPM modules that were evaluated.
