Field experiment carried out at ARS, Dharwad during 2013-14 to study the effect of seed treating chemical and spray formulations on morpho-physiological traits and their impact on sucking pests incidence in Bt cotton. Seed treatment with Imidacloprid 70WS registered higher seedling vigour index of 1089.00 as compared to 1053.00 in Thiamethoxam 35FS. Further, highest leaf specific weight of 0.043 g/cm2 was registered in Imidacloprid 70WS treated seeds were sown and sprayed with Imidacloprid 17.8SL. Similarly, Imidacloprid 17.80SL was sprayed as subsequent sprays registered higher relative water content of 88.87 per cent. Among the treatments, seed treatment with Imidacloprid 70WS followed by Imidacloprid 17.8SL spray recorded higher chlorophyll content (1.31 mg/g) followed by seed treatment with Thiamethoxam 35FS and Imidacloprid 17.80SL spraying (1.30 mg/g). Initially, population of thrips and leaf hopper was on lower side and there was gradual increase in the pest population after the subsequent sprays with Imidacloprid 17.80SL.
