abstract
Pooled analysis of two Rabi seasons (2016-17 and 2017-18) data on bioefficacy of spirotetramate 120 + imidacloprid 120 SC (W/V) on onion indicated that two rounds of foliar application of the insecticide @ 75 + 75 g a.i./ha starting from Economic Threshold Level (ETL) of thrips was significantly superior in reducing the nymphs and adults of Thrips tabaci and observed the survival population in the range (5.67-11.00 thrips/plant) as against (24.83-27.20 thrips/plant) in untreated control. However, the treatment with spirotetramate 120 + imidacloprid 120 SC (W/V) @ 60 + 60 g a.i./ha was found at par with this treatment and observed the population of thrips in the range (6.60 – 12.50 thrips/plant). Whereas, in respect of yield of onion bulbs also these two treatments viz; spirotetramate 120 + imidacloprid 120 SC (W/V) @ 75 + 75 and 60 + 60 g a.i./ha recorded maximum bulb of yield i.e. 257.40 and 249.90 q/ha respectively, as against 162.10 q/ha in untreated control.
