Bio-efficacy of insecticide, Cyclaniliprole 100 DC against gram pod borer, Helicoverpa armigera Hubmer. Infesting chickpea

The present investigation was conducted at Ariculture Research Station, Hanumanamatti, University of Agricultural Sciences, Dharwad during rabi Season. Gram pod borer Helicoverpa armigera larval population was observed from vegetative stage of the crop. The peak population of gram pod borer were observed from flowering stage. The new insecticide molecule Cyclaniliprole 100 DC different dosages Viz., 30,35 and 40 g a.i./ha gave significantly highest in reduction of larval population compared to Chlorantraniliprole 18.5 SC @ 25 g a.i./ha and Novaluron 10% EC @ 75 g a.i./ha without causing any significant effect on natural enemies. The highest yield was obtained from Cyclaniliprole 10% DC @ 40 g a.i /ha treated plots (13.25 q/ha) which was statistically at par with the treatment of Cyclaniliprole 10% DC @ 35 g a.i/ha, Chlorantraniliprole 18.5 SC @ 25 g a.i./ha and Cyclaniliprole 10% DC @ 30 g a.i./ha (12.92, 12.80 and 11.71 q/ha, respectively).
