Rice
The symptoms on leaves are round or oval brown spots with yellow halos. The disease can cause significant economic losses if not controlled. Eventually, it will manifest on glumes and seeds that lead to yield reduction.
Brown leaf spot is a fungal disease that affects rice fields all over the world. Brown leaf spot favors high humidity, but is capable of developing in a range of temperatures. The fungi is more common in unflooded fields and where soils suffer nutrient-deficiencies. Important sources of brown leaf spot outbreaks are infected seeds in which the fungi are able to survive for several years and the air through the aid of wind.
Cuanto antes, mejor: es más fácil y más rentable superar la infestación durante las etapas iniciales. Haga una rutina de monitoreo regular en el campo y mire las plantas para detectar la presencia de los síntomas anteriores.
El uso de semillas libres de enfermedades y de alta calidad es el primer paso que siempre se recomienda
Use variedades que sean resistentes a la enfermedad.
Mantenga un espacio adecuado entre plantas: evite la sobre densidad para permitir que la luz penetre.
Adequate fertilization: Overuse of nitrogen fertilizers can increase new infections of rice blast, but often fail to significantly increase yields
Saneamiento: Mantenga limpios los entornos y las condiciones ambientales de su cultivo eliminando las malezas y plantas cercanas que no están cultivadas o protegidas.
