Abstract

Urdbean is one of the important grain legume crops grown in India mainly for protein and nutrition. However, the production and productivity were very little due losses caused by various viral diseases from seedling to harvesting stage. Guntur district being the major pulse region of the Andhra Pradesh annually suffers from incidence of various viral diseases in urdbean. A comprehensive and systematic survey was carried out with the main objective to determine the incidence and prevalence of Mungbean Yellow Mosaic Virus (MYMV) and other viral diseases of urdbean during kharif and rabi 2019-2020 in ten major urdbean growing mandals in Guntur district of Andhra Pradesh. The results revealed a huge variation in incidence of all the viral diseases among the surveyed mandals and also within the mandals. However, the study recorded the highest overall mean incidence and severity of MYMV (13.54% and 20.18% during kharif; 22.08% and 30.32% during rabi) followed by leaf crinkle incidence (17.86

Conclusion

diseases were observed in all the mandals surveyed in Guntur district of Andhra Pradesh in both kharif and rabi. Further, a huge variation in incidence of all the three diseases of urdbean was recorded. Highest overall mean incidence and severity of MYMV (22.08% and 30.32%) was observed in rabi rather than kharif, whereas the highest overall mean incidence of leaf curl (16.06%) and leaf crinkle (17.86%) was showed in kharif rather than rabi. Based on survey analysis, the study clearly showed that rabi season is more favorable for the incidence and severity of MYMV, whereas kharif season highly congenial for the incidence of leaf curl and leaf crinkle virus. The study concludes that management of viral diseases could be done depending upon the incidence level season based. To minimize the devasting effects of caused by various viruses in urdbean, sustainable vector and disease management options need to be established, tested and deployed including the use of resistant and/or tolerant v
