Evaluation of newer insecticides against spotted pod borer and its pod damage in summer green gram

Abstract

Green gram (Vigna radiata L. Wilczek) is a major pulse crop belongs to the family Leguminaceae (sub-family: Papilionaceae). The spotted pod borer (Maruca vitrata Fabricious) is one of the most important and destructive pest of green gram (Vigna radiata L. Wilczek). Thus, seven insecticides viz., indoxacarb 14.5 SC 0.012%, chlorantraniliprole 18.5 SC 0.0055%, emamectin benzoate 5 SG 0.0025%, flubendiamide 20 WG 0.012%, diafenthiuron 50 WP 0.060, imidacloprid 17.8 SL 0.0055%, flonicamid 50 WG 0.015% were evaluated against spotted pod borer larval population at Navsari Agricultural University, Navsari, Gujarat during summer season of 2021 and 2022. Among evaluated insecticides, chlorantraniliprole 18.5 SC and flubendiamide 20 WG were most effective against larval population as well as pod damage caused by spotted pod borer in green gram.
