Abstract

Field trial was conducted during two Kharif consecutive seasons 2008 and 2009 for testing the bioefficacy of bio-inoculants against major pests of mung bean at research farm of Centre of Excellence for Research on Pulses, S. D. Agricultural University, Sardarkrushinagar. Based on pooled results, seed treatment of imidacloprid (5 g/kg seeds) and foliar spray of profenophos (2 ml/lit.) were found effective against leafhopper and Maruca vitrata. Use of microbial bioinoculants can substitute the conventional pesticide use in short duration crops like mungbean and it reduces the pesticidal hazards. However, significant effect was also observed in the bioinoculants applied plots on the sucking insects and pod damage by Maruca vitrata. Psuedomonas fluorescens (10 g/kg seeds) seed treated plots and spraying of profenophos (2 ml/lit.) at 50 per cent flowering was found effective against leafhopper and Maruca as well as in achieving higher yield of mung bean.

Abstract

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
