Gray mold caused by Botrytis cinerea limits grape production in Chile

摘要: Gray mold (GM) caused by Botrytis cinerea is a major disease of grapes ( Vitis vinifera ) that substantially reduces the yield and quality grape production in temperate humid regions world. B. necrotrophic fungus attacks non-lignified aerial organs grapes; particular, berries are highly susceptible during ripening. The polycyclic nature exponential progress exhibited GM at beginning its epidemic, as well abundant inoculum production, high dissemination efficiency, wide host range genetic variability , explain difficulties encountered attempting to control GM. At present, integrated management, including cultural chemical control, main strategy. These measures can be used reduce initial or lower infection rate. However, rate most effective means controlling Important toward understanding complexity biology epidemiology this pathogen has occurred recent decades. This allowed improvement development more sustainable strategies against . review article provides update regarding GM, with special emphasis on Chilean conditions. La pudricion gris (PG) causada por cinerea, es una de las principales enfermedades la vid que limita produccion y los rendimientos calidad fruta en zonas templadas humedas nivel mundial. un hongo necrotrofo ataca organos aereos no lignificados vid, siendo bayas altamente susceptibles durante maduracion. naturaleza policiclica el desarrollo exponencial epidemias PG, junto con abundancia inoculo, eficiente dispersion mas amplio rango hospederos gran variabilidad genetica presenta explican dificultades para lograr satisfactorio. Ante lo cual se hace necesario realizar estrategia integrado incluya medias quimico. Estas medidas pueden estar orientadas reducir inoculo inicial o tasa progreso enfermedad, destinadas aporta al PG. En ultimas decadas han producido importantes progresos conocimiento compleja biologia este patogeno aspectos epidemiologicos Esto ha permitido mejorar estrategias logrando alternativas efectivas sustentables. articulo revisan aportes cientificos recientes realizados relacion PG teniendo especial enfasis situacion del vinedo chileno.
