针对白粉病再侵染频繁,流行强度较大的特点,在新疆于发病始期喷布无毒高脂膜,共施用2—3次,防病效果达80%以上,相当于常规农药防效。高脂膜防病增产效果较明显,一般为20%左右;高脂膜施用区,哈密瓜可溶性糖分提高1—2度。在新疆,利用高脂膜防治哈密瓜白粉病已达3万亩。 In view of the frequent re-infection of powdery mildew and the strong epidemic intensity, the non-toxic high-fat film was sprayed on the onset of Xinjiang in 2-3 times. The preventive effect was more than 80%, which was equivalent to that of conventional pesticide. High-fat film disease prevention and yield increase effect is more obvious, generally about 20%; high lipid membrane application area, melon soluble sugar increased 1-2 degrees. In Xinjiang, the use of high fat film control melon powdery mildew has reached 30,000 mu.
