Development of diagnostic tools and host plant resistance to control the rapid spread of lettuce big vein and ring necrosis diseases in leafy vegetables

Ziel

Lettuce big-vein and leaf necrosis disease are the most serious of soil-burns fungus-transmitted viral diseases in leafy vegetables in Europe. They are extremely difficult to control because of the lack of major resistance genes in the current varieties and the persistence of resting spores of the fungal vectors, Ophidian brasslike. Direct economic losses in lettuce production alone run in excess of 50 million euro per year in Europe. To control the rapid spread, growers heavily depend on soil sterility (some are to banned) against the fungal vector. The deliverables of the proposed work allow a dramatic reduction in pesticide inputs and the development of a sustainable system for the production of lettuce and other leafy vegetables through the integration of several control measures, including identification and exploitation of natural host plant resistance and the development of a management system based on disease avoidance.
