近几年伊犁地区葡萄霜霉病发生较重,农民一般都是在霜霉病发生后,才采用内吸治疗性杀菌剂进行防治,往往打十几次药,效果不理想还为生产无公害产品带来隐患,伊犁州植保站从2002年开始在葡萄霜霉病发生前期采用保护性杀菌剂进行防治,取得了很好的效果。 Grape downy mildew occurred heavier in Yili region in recent years. The peasants generally used the therapeutic bactericides to prevent and cure them after the onset of downy mildew, which often hit a dozen times with unsatisfactory results. The product poses a hidden danger. The Yili Plant Protection Station has been using protective fungicides to prevent and cure grape downy mildew since 2002, and has achieved good results.
