abstract
Studies were conducted to evaluate new formulation of seed dressing chemical like imidacloprid 60 FS (10 & 20 ml/kg seed) and thiamethoxam 35 FS (15 & 30 ml/kg seed) at MARS, Raichur and ARS, Bidar during 2015-16 to 2017-18. These two chemicals earlier available as 70 WS but now their formulation has changed to FS (Formulation of seed) hence in order to work out the effective dosage of new formulations of above chemicals were tested at different dosages among them imidacloprid 60 FS @ 20 ml/kg seed registered minimum thrips population of 4.42 and 2.87 per leaf from MARS, Raichur and ARS, Bidar respectively hence it could harvest highest fruit yield of 24.6 and 23.95 q/ha with a B:C ratio of 2.20 and 2.14 from former and later treatments respectively. However, this treatment showed non-significant difference with thiamethoxam at higher dosage of 30 ml/kg seed which registered 3.96 and 1.44 thrips per leaf from MARS, Raichur and ARS, Bidar respectively. The fruit yield obtained from these two treatments were 26.35 and 25.60 q/ha with a B:C ratio of 2.36 and 2.29.
