Resumen de Recent progress in understanding the genetics of pest and disease resistance in grapevine
Grapevines are highly susceptible to a wide range of pests and microbial pathogens including insects, nematodes, fungi, oomycetes, bacteria, phytoplasmas, viruses and viroids. Historically, grape growers have relied heavily on the use of pesticides and fungicides, in combination with various management techniques, to minimise the impact of these pathogens. There is, however, increasing financial, regulatory and market pressure on grape growers to minimize the application of agro¬chemicals in the vineyard. For example, the European Commission recently proposed a ban on the use, by 2013, of a large number of agrochemicals, which are routinely used for the control of grapevine fungal diseases. In the face of these increasing pressures, the development of new grapevine cultivars with improved ?natural? genetic resistance to pathogens is a high priority.
