abstract
Studies were conducted to evaluate the effect of new formulations of seed dressing chemicals viz., Thiamethoxam 35 FS and Imidacloprid 60 FS at different concentrations against the sucking insect pests of okra viz., thrips and leafhopper using the most popular Arka Anamika variety during 2015, 2016 and 2017 at different regions of north eastern zones of Karnataka like Main Agricultural Research Station, Raichur (Zone-2) and Agricultural Research Station, Bidar (zone-1). Earlier these two chemicals formulation were available as 70 WS, but now these chemicals formulation has changed to FS (Formulation of seed). Hence studies were conducted to evaluate the effective dosage of these two chemicals. Among them imidacloprid at 10 ml per kg seed recorded minimum number of 3.39 and 2.50 thrips per leaf and 1.18 and 1.49 leafhopper population per leaf from MARS, Raichur and ARS, Bidar respectively. However, this treatment found to be on par with thiamethoxam 35 FS @ 15 ml/kg seed. Further, the fruit yields obtained from these two treatments were 122.53 and 125.30 q/ha with a B: C ratio of 3.40 and 3.48 respectively.
