Abstract:
In the evaluation of different botanical insecticides, different botanicals and insecticides were applied at 25, 45 and 65 DAT under a treatment. The experiment was performed at Research cum Instructional farm of SGCARS, Jagdalpur. The results revealed that T₁ (Combination of Neemazal 1% EC @ 2 ml L^-1, Eucalyptus oil @ 2 ml L^-1 and Cartap hydrochloride 50% SC @ 2 g L^-1) was most effective combination with 40.74%, 63.09%, 54.29% and 56.44% ROC respectively for gall midge, stem borer, leaf folder and whorl maggot infestation. This treatment was superior to T₂ (Neemazal 1% EC @ 2 ml L^-1, Neemoil @ 10 ml L^-1 and Triflumezopyrim 10% SC @ 0.48 ml L^-1) having 36.69%, 59.32%, 52.16% and 47.99% ROC, respectively for gall midge, stem borer, leaf folder and whorl maggot infestation. The least effective combination was T₃ (Neemazal 1% EC @ 2 ml L^-1, Eucalyptus oil @ 2 ml L^-1 and Neemoil @ 10 ml L^-1) with 29.19%, 48.75%, 41.27% and 35.81% ROC for gall midge, stem borer, leaf folder and whorl maggot, respectively but it was superior to T₅ (untreated control). The check treatment T₄ (Chlorantraniliprole 0.4G @ 1 g/m², Cartap hydrochloride 50% SC @ 2 g L^-1 and Triflumezopyrim 10% SC @ 0.48 ml L^-1) had the highest ROC of 64.52%, 86.60%, 83.08% and 74.61% ROC for gall midge, stem borer, leaf folder and whorl maggot, respectively.
