稻曲病是危害水稻的一种重要病害,农民形象地称它为“灰包”。近20年来,该病有逐年加重的趋势,受稻曲病危害,受害谷粒颖壳张开露出淡黄带青色块状物,以后逐渐膨大包裹整个谷粒,使病粒比健粒大3~4倍,色泽变墨绿,表面呈粉状,最后表面龟裂,布满墨绿色粉末,所以农民把这种病害称作“灰包”、黑粉病。它不仅造成减收,且影响米质,危害人体健康,感染稻曲病的谷粒,在贮藏过程中一般不会继续危害,但若谷粒上带菌量多,遇到高温高湿环境时也能继续发展,对粮食安全贮藏构成一定的威胁。目前,防治 False smut is an important disease that endangers rice. Farmers vividly call it a “gray pack.” Over the past 20 years, the disease has been increasing year by year, affected by the disease caused by rice germ, damaged grain glume open yellowish green band with a block of light, after the gradual enlargement of the entire grain package, so that particles larger than the healthy grain ~ 4 times the color change dark green, the surface powder, the last surface cracked, covered with dark green powder, so farmers call this disease “gray package ”, smut. It not only reduces the grain yield but also affects the quality of rice and endanger human health. The grains that are infected with False Smut are not usually harmed during storage. However, if the grains are inoculated with more bacteria, they can also be exposed to high temperature and high humidity Continued development poses a certain threat to the storage of food security. At present, prevention and treatment
