小麦赤霉病也称镰刀菌穗枯病,是世界上湿润和半湿润小麦生长区的一种毁灭性病害。J.C.Arthur 曾纪录过1890年印第安纳州爆发小麦赤霉病的情况,观察到一块很有希望获得2350～2690kg/hm~2(35～40)蒲式耳/AC(英亩)产量的麦田,却因该病害而只获得538kg/hm~2(8蒲式耳/AC)的收成。那次赤霉病的发病率为25%～75%。近期在美国东部软红冬小麦生产区也有几次赤霉病爆发。1927～1980年间加拿大安大略西南部约9
Wheat head blight, also known as Fusarium head blight, is a devastating disease in the wet and sub-humid growth areas of the world. JCArthur documented the outbreak of wheat scab in Indiana in 1890 and observed a promising wheat field of 2350 to 2690 kg / hm 2 (35 to 40) bushels per acre yield, Only 538 kg / hm2 (8 bushels / AC) crop was obtained. The incidence of that scab is between 25% and 75%. Several recent blight outbreaks have also occurred in soft red winter wheat producing areas in the eastern United States. 1927 ~ 1980, about 9 in southwestern Ontario, Canada
