小麦赤霉病是我省小麦生产上的主要病害。1985年在我省造成了严重的损失。1986和1987年发病面积一千万亩左右。小麦赤霉病为气候性病害。近年来,随着气候条件的变化和耕作制度的改革,已跨过长江,越过黄河,并逐渐向北扩展。目前,生产上推广的小麦品种还没有免疫品种,也缺乏抗病品种,化学农药乃是防治小麦赤霉病的主要手段。1986年我们选用15种杀菌剂、在全省多点试验,从中选出8种杀菌剂在1987年再次进行研究,以找出防治小麦赤霉病的最佳药剂和施药技术以指导大面积防治。
Wheat scab is the main disease in wheat production in our province. In 1985, it caused serious losses in our province. In 1986 and 1987, the disease area was about 10 million mu. Wheat scab is a climatic disease. In recent years, with the change of climatic conditions and the reform of farming system, it has crossed the Yangtze River, crossed the Yellow River, and gradually expanded northward. At present, there is no immune variety and no resistant variety in wheat varieties promoted in production. Chemical pesticides are the main means of preventing and curing wheat scab. In 1986 we selected 15 kinds of fungicides, more tests in the province, from which eight kinds of fungicides were selected in 1987 to conduct a further study to identify the best prevention and treatment of wheat scab and the application of pharmaceutical technology to guide the large area Prevention and treatment.
