为了寻求防治甜瓜叶枯病、细菌性角斑病的有效药剂及使用浓度,给大面积防治提供依据,1985年我们进行了药剂防治试验。试验分温室和大田两部分。 一、代森锰锌防治温室甜瓜叶枯病试验 甜瓜叶枯病是我区甜瓜的重要病害,1984年大发生,不少单位终因缺少有效的防治药剂而损失严重。1985年我们从江苏南通第三化工厂引进新型高效杀菌剂 In order to seek effective prevention and cure of melon leaf blight, bacterial angular leaf spot and the use of effective concentration, to provide a basis for large-scale prevention and control, we conducted a chemical control test in 1985. Test sub-greenhouse and field two parts. First, the prevention and control of mancozeb in greenhouse greenhouse melon leaf blight test melon leaf blight is an important disease of melon in our district, occurred in 1984, many units eventually due to the lack of effective control agents and the loss of serious.
