小麦赤霉病是长江中下游冬麦区小麦生产上的一种重要病害。由于近几年特殊的气候条件,使得历史上很少在北方冬麦区大面积发生的小麦赤霉病,在河北省中南部麦田严重流行,已成为小麦生产上的重要病害。赤霉病不仅引起小麦直接减产,而且对麦粒的品质和利用价值影响严重。造成病麦出粉率低,面粉质量差,色泽灰暗,面筋含量减少,商品价值降低。病麦中含有致病的镰刀菌代谢产物,含有致呕毒素 Wheat scab is one of the most important diseases in wheat production in the winter wheat region of the middle and lower reaches of the Yangtze River. Due to the special climatic conditions in recent years, wheat head blight rarely occurs in the winter wheat area in the north and has become a serious disease in the wheat production in central and southern Hebei. Fusarium head blight not only causes the direct wheat yield but also has a serious impact on the quality and utilization value of the grain. Resulting in low yield of wheat flour, flour quality is poor, dark gray color, reduced gluten content, lower commodity value. Sick wheat contains pathogenic Fusarium metabolites, containing strychnine
