水稻纹枯病与稻瘟病和稻白叶枯病同为本省水稻的三大病害,群众称之为“花秆”、“花脚膀”、“梅鹿秆”等。此病主要以散落在田间的菌核越冬传布。在水稻丛间温度达到23℃,相对湿度达97%以上时初次侵染为害;其后稻丛间温度在22℃以上,相对湿度超过90%即适合此病发展,并随湿度的增高而加速蔓延。病害的初发期与稻丛间温、湿度关系密切,
Rice sheath blight and blast and rice leaf blight are the three major rice diseases in the province, the masses call it “flower stalk”, “flower foot”, “Merlot stalks” and so on. The disease mainly scattered in the field sclerotium overwinter spread. When the temperature between rice clumps reaches 23 ℃ and the relative humidity reaches more than 97%, the first infestation will occur. Afterwards, the intercropping temperature is above 22 ℃ and the relative humidity above 90% is suitable for the development of the disease and will accelerate with the increase of humidity spread. The initial stage of disease and rice plexus temperature and humidity are closely related,
