Abstract
Field experiments have been formulated to minimise the groundnut pod damage by seed treatments and soil drenching. The pooled data revealed that Seed treatment with clothionidin 50 WDG @ 2 g kg-1 recorded 12.24% pod damage during peg formation stage. During maturity stage, seed treatment with imidacloprid 600 FS @ 2 ml kg-1 + soil drenching with chlorpyriphos 20 EC @ 8 ml per 10 L of water at 60 DAS recorded 15.11% pod damage and the imidacloprid seed treatment with soil drenching of imidacloprid 17.8 SL, chlorpyriphos 20 EC and imidacloprid 40% + fipronil 40% (80 WG) were on par with each other. Highest pod yield (1,475 kg ha-1) and haulm (2,958 kg ha-1) with 17.22 ICBR was observed in imidacloprid seed treatment with soil drenching of imidacloprid 17.8 SL. Untreated control recorded 23.97% pod damage with 971 kg pod and 1,975 kg haulm.
