Beating tungro virus disease in rice. Validated RNRRS Output.


This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Principally based on Projects R6519, R5243, R5244, R5245. A suite of new techniques to tackle the devastating rice losses caused by tungro is now helping small-scale farmers in Indonesia, the Philippines and India. Better understanding of the leafhopper insect that spreads the virus has led to better growing practices, especially late planting. New resistant rice varieties have been produced, as well as a spatial model which helps identify the best strategies to cut the incidence of disease. A simple, reliable and relatively low-cost diagnostic kit for the virus has also been developed to help rice breeders and extension services. Farmers in Bali (Indonesia) are already growing the improved varieties on over 40,000 hectares, while farmers in East Java and Lombok (Indonesia), and Mindanao and the Visayas (Philippines) are also benefiting. Training manuals are also available.
