Abstract
The field experiment, conducted at Agricultural Research Station, Faculty of Agricultural Sciences, SOADU, Binjhagiri, Khordha, during summer 2021, aimed to assess the efficacy of new insecticides against thrips in green gram and their impact on crop yield. Treatments applied at 20 and 40 days after sowing (DAS) demonstrated superiority over the control. Diafenthiuron 50 WP at 250 g a.i./ha exhibited the highest efficacy, resulting in more than a 80% reduction in thrips population. Other highly efficacious treatments included thiamethoxam 25 WG @ 25 g a.i./ha, spiromesifen 240 SC @ 150 g a.i./ha, fipronil 5 SC @ 50 g a.i./ ha, and imidacloprid 17.8 SL @ 25 g a.i./ha, each contributing to nearly 70% reduction in thrips population. Clothianidin 50 WDG @ 125 g a.i/ha was identified as the least effective, providing nearly 65% reduction in thrips population. All tested newer insecticides effectively reduced sucking insect pests in green gram.
