小麦白粉病是我省小麦主要病害之一,在川东地区为害尤为严重,给农业生产造成很大损失。在目前缺乏有效抗病品种的情况下,筛选高效、低毒、低残留的化学防病药剂与摸索简单的施药方法,是保证小麦高产稳产的当务之急。高脂膜(植物防病膜、单分子膜)是70年代中期开始试用的新型防病膜剂,无毒无害,喷在植物体表面后能形成肉眼看不见的膜,不影响植物体表正常的气体交换,但可以改变植物体表面的微气候,进而抑制病菌孢子萌发,阻止其对植物体表的侵染。韩金声等在1979～1981年试用高脂膜剂 Wheat powdery mildew is one of the major diseases of wheat in our province, especially in the eastern part of Sichuan Province, causing great losses to agricultural production. In the current lack of effective disease-resistant varieties, the screening of high efficiency, low toxicity, low residual chemical anti-pathogenic agents and explore simple application methods, is to ensure high-yield wheat top priority. High-fat film (plant disease prevention membrane, monolayer) is a new antifungal agent tested in the mid-1970s. It is non-toxic and harmless. It can form invisible membrane after spraying on plant surface without affecting plant surface Normal gas exchange, but can change the micro-climate on the surface of plants, thereby inhibiting the germination of germs spores, to prevent its on the plant surface infection.
