Abstract/Description: | Yellow leaf disease (YLD) caused by sugarcane yellow leaf virus is recorded in almost all the sugarcane growing countries in the world. The disease was observed during 1999 in the country for the first time and later its wide spread occurrence throughout country was found. In popular varieties, the disease intensity varied from 0 to 100 % and the disease incidence varied from 0 to 75.0% under field conditions. The expression of symptoms under field conditions was influenced to a limited extent by different biotic and abiotic factors. Severe infection of YLD was found to significantly affect cane yield and juice quality in certain cultivars. YLD infected sugarcane plants recorded lesser photosynthetic activity and reduced mobilization of photosynthates from the leaves to sink, thereby reducing the sucrose accumulation in the affected stalks. Planting of setts from virus infected canes has been found as the chief source of disease introduction in the field and secondary transmission of the disease through aphid vectors has been reported to varying extent. Detailed studies based on serological (ELISA) and molecular techniques (RT-PCR) conducted at the institute have confirmed the association of sugarcane yellow leaf virus (SCYLV) with the disease. Among the different management approaches, clean seed programme is found to be the most effective to control the disease. Elimination of the virus through meristem culture has been demonstrated to purify the virus infected planting material. Hence a healthy seed nursery programme is suggested to manage the disease for the sustainable sugarcane production |
