Evaluation of Bio-inoculants for Ecofriendly Management of Major Pests of Mung Bean (vigna Radiata l.)

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.
