Abstract

Efficacy of insecticides against diamond back moth in cauliflower revealed that among all the treatments significantly lower larval population and higher yield was obtained with chlorantraniliprole 18.5 SC @ 0.006%. It was at par with spinosad 45 SC @ 0.009% followed by emamectin benzoate 5 WSG @ 0.002% and flubendiamide 39.35 SC @ 0.096%. Maximum avoidable loss of 45.24% and higher yield (19.98 t/ha) was obtained with chlorantraniliprole followed by spinosad. Maximum cost benefit in terms of ICBR was observed with spinosad 45 SC @ 0.009% (1: 9.93) followed by emamectin benzoate 5 WSG @ 0.002% (1: 8.64).
