Efficacy of some seed plant protectants against Caryedon serratus (Olivier) infesting Groundnut

The present research was aimed to study the efficacy of different plant powders and oils against Caryeon serratus (Olivier) on groundnut. The neem oil was the most effective treatment in reducing the adult emergence of Caryeon serratus (Olivier) on groundnut. The mean per cent adult emergence in different treatments ranged from 14.85 to 31.16, being minimum in neem oil, while maximum in annona leaf powder treatment. Pod damage and loss in weight were minimum in the pods treated with neem oil followed by castor oil, neem kernel powder, neem leaf powder, bakan leaf powder and annona leaf powder. The effect of some plant materials as powders and oils was found to be significantly more superior in reducing the pod damage and loss in weight in comparison to control.
