    Abstract

    Studies were conducted to identify the susceptible stage and symptomatology of urd bean leaf crinkle virus (ULCV) on urd bean. The incubation period was short and symtoms developed on second trifoliate leaf stage onwards when the plants were inculated at younger stage as compared to older plants. In the infected plants the increase in leaf size was evident from third trifoliate leaf stage onwards. Reduction in rachis length of terminal leaflet of infected trifoliate and thickening of stem and petiole were evident in infeceted plant. The size of stipules increased prior to the symptom development in lamina in all the infected plants These symptoms are of great use in eliminating infected plants in the early stages for effective management of the disease.
