Description Six plant extracts viz., Mirabilis jalapa, catharanthns roseus, Datura metal, Bougainvillea spectabilis, Boerhaavia diffusa and Azadirachta indica were recorded maximum reduction of urd bean leaf crinkle virus (ULCV) incidence in urd bean crops at field level. Among the antiphytoviral chemicals tested, DHT reduced the transmission to the maximum extent and increased the incubation period of virus in the urd bean plant. Fresh buttermilk was significantly superior to fermented buttermilk in reducing the disease spread and increasing the incubation period of the virus in the plant. Casein was found effective in reducing the per cent transmission and increased the incubation period of the virus. Raising barrier crops viz., maize, sorghum and pearl millet were equally effective in reducing the spread of the disease in field. Spraying of DHT at two intervals, 7 and 22 DAS was found effective in reducing the disease spread when compared with Thuja, buttermilk, M. jalapa and neem oil.
