Year: 2023
Type: article
Abstract: Six insecticides and untreated control were evaluated against sorghum spotted stem borer, Chilo partellus, among these, emamectin benzoate 5% SG @ 9.5 g a.i./ha recorded significantly lowest per cent dead hearts (15.8% DH) followed by thiamethoxam 25% WG @ 25 g a.i./ha (16.5%), flubendamide 20% WG @ 25 g a.i./ha (17.6% DH), rynaxypyr 0.4% G @ 30 g a.i./ha (18.0% DH) which were on par with each other as compared to other treatments. The highest percentage of dead hearts was found in untreated control (32.9% DH). Rynaxypyr 0.4% G @ 30 g a.i./ha and thiamethoxam 25% WG @ 25 g a.i./ha had significantly lower leaf injury damage ratings and lower per cent stem tunnelling than other treatments (DR: 1.8 and 18.9%, respectively), followed by emamectin benzoate 5% SG @ 9.5 g a.i./ha (DR: 2.0 and 26.3%). The highest damage rating and percentage of stem tunneling was observed in untreated control (DR: 4.0 and 50.1%). Thiamethoxam 25% WG @ 25 g a.i./ ha (15.2 q/ha) produced significantly the maximum sorghum grain as compared to other treatments.
