今年麦收前夕,我们做田间调查时发现,湖北省中南部麦区有几十个县(市)不同程度地发生了小麦散黑穗病,部分高产示范地和繁种田也有零星发病,应引起重视。小麦散黑穗病是通过种子带菌传染和传播的,种子药剂处理是防治此病的关键,一旦出现“黑穗”症状,就已经无药可治了。 On the eve of the wheat harvest this year, when we conducted field surveys, we found that there were dozens of counties (cities) in central and southern Hubei Province that suffered from scattered smut to varying degrees and that some high-yielding demonstration plots and scattered farming fields also had sporadic occurrences that deserved serious attention . Wheat smut is transmitted and transmitted through seed carriers, seed treatment is the key to the prevention and treatment of the disease, once the “black ear” symptoms, it has no cure.
