黄瓜霜霉病是黄瓜生产中的主要病害之一,几年来,鞍山地区多采用代森锌、乙磷铝等药剂进行防治,虽然取得一定的效果,但仍不理想。为了筛选出高效、低毒、安全、杀菌广谱而又能兼治其它病害的新型杀菌剂,我们对瑞士汽巴公司进口的瑞毒霉和沈阳农药厂产的代森锌进行混用和单用的田间药效试验。供试的药剂种类有瑞锌1号、瑞锌2号、瑞锌3号、35%瑞毒霉、40%乙磷铝、80%代森锌,以喷清水为对照。7月1日黄瓜植株发病后第一
Cucumber downy mildew is one of the main diseases in cucumber production. Over the past few years, Anshan Zinc, Cefotaxime and other agents have been used in Anshan for prevention and treatment.
