dc.description.abstractThe present study was conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana (India). A total of 20 genotypes were taken for screening against M. vitrata (Geyer) on pigeonpea and its management. Total pod damage by M. vitrata ranged from 32.7 to 68.45 per cent. The genotypes AH10-17, UPAS-120, AL 201, AH 12-06 were found to be least susceptible (PSR-4) against M. vitrata . Maximum larval population and number of webs of M. vitrata were recorded in 41 st standardweek . Morphological characters i.e. Days to 50 per cent flowering, number of grains, pod wall thickness and days to maturity have no influence on M.vitrata susceptibility, however, pod length was found positively correlated and trichome density (type A and type C) negatively correlated with M. vitrata infestation . The biochemical characteristics of infested and healthy leaves and pods of different pigeonpea genotypes i.e. total sugars and proteins had positive effect on M. vitrata infestation, while phenols contributed negative effect. The efficacy of different management practices revealed that rynaxypyr18.5 SC, emamectin benzoate 5 SG and spinosad45 SC were found to be most effective against larval population and webs of M .vitrata where as intercropping with sorghum and Bacillus thuringiensis var. kurstaki were found to be least effective and maximum incremental benefit cost ratio was recorded on emamectin benzoate 5 SG (12.53) while, minimum on B. thuringiensis var. kurstaki(1.22).en_US
