Evaluation of Botanicals for Management of Pulse Beetle, callosobruchus Maculatus in Stored Green Gram

Different plant powders and plant oils were evaluated for their grain protectant efficacy against C.maculatus in green gram (variety GM-4). Custard apple seed powder (25g /kg seed), orange peel powder (150g/kg seed), coconut oil (10 ml/kg seed) and clove oil (10 ml/kg seed) completely prevented oviposition, adult emergence and grain damage on number and weight base even after four months of storage and found most effective grain protectants, while clove flower bud powder (10 flower buds powder/kg seed) and red chilli fruit powder (5 g / kg seed) allowed cent per cent damage due to high oviposition and adult emergence after four months of storage and found ineffective as grain protectants, but significantly less than neem seed kernel powder, neem leaf powder (both, 25 g/kg seed), chrysanthemum flower powder and pomegranate peel powder (both, 25 g/kg seed) which were found least effective grain protectants against C. maculatus. Groundnut oil, olive oil and safflower oil (all at 10 ml/kg seed) were also found effective grain protectants. Rest of the treatments viz., neem seed kernel powder, neem leaf powder (both, 25g/ kg seed), chrysanthemum flower powder and pomegranate peel powder (both, 25g/ kg seed) which were found least effective grain protectants against C. maculatus
