abstract
Studies were conducted to evaluate the efficacy of different botanicals against the diamondback moth on cabbage at the Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during rabi season of years, 2015-16 and 2016-17 in variety “Golden Acre”. Among which its order of effectiveness during first spray was observed as Azadirachtin (1.52 larvae/plant) > Chilly+ Garlic solution (1.53 larvae/plant) > Neem seed powder extract (1.66 larvae/plant) > Karanj seed powder extract (1.70 larvae/plant) > Karanj oil solution (1.77 larvae/plant) > Neem oil solution (1.80 larvae/plant) > Neem cake petrol extract (1.89 larvae/plant)> Mahua oil solution (1.93 larvae/plant) and highest per cent reduction over control after first spray was recorded in Azadirachtin (36.66%). With similar trend during second spray, lowest population of DBM larvae was recorded in Azadirachtin (1.21 larvae/plant) followed by Chilly+ Garlic solution (1.41 larvae/plant) and Neem seed powder extract (1.49 larvae/plant) and their order of per cent reduction over control for second spray was found highest in Azadirachtin (56.93%). Effect of Azadirachtin on yield of cabbage heads (202.12 q/ha) was found superior over rest of the treatments.
