Abstract:
Mungbean (Vigna radiata (L.) Wilczek) is a very ancient annual crop in. Indian farming which is commonly known as greengram, green bean, moong, mash bean, golden gram and green soy. Mungbean originated.in India or the Indo- Burmese region. The standard yield of mungbean worldwide is very low (730 kg/ha) and the mungbean production has not increased yet to the potentials. The main reasons for the low yield do fungus, virus, bacterium, insect, weed etc. Out of all diseases of mungbean. MYMV disease is one of the most prevalent and destructive diseases. MYMV in the southern and northern states is currently causing serious concern to mungbean growers and to the industrialist in these regions. The most vulnerable stage is from 30 to 45 days. MYMV a member of Geminiviridae family, belong to genus Begomovirus that was identified in 1955 and it was observed that it is not transmitted mechanically but transmitted by whitefly (Bemisia tabaci Genn) in persistent manner. All the biorational approaches significantly reduced MYMV PDI and with increase in the yield as compared to control. Salicylic acid as seed priming and then foliar spray have maximum per cent disease control followed by sarpagandha leaves extract as seed priming which was statistically at par to that recorded for neem oil as seed treatment. The salicylic acid, sarpagandha leaves extract and neem oil were effective to increase yield and test weight.
