通过室内防治效果测定研究几种生物药剂对黄瓜白粉病、灰霉病的防治效果,获得防治效果较好的生物药剂种类,从而为黄瓜田间防治应用提供依据。试验结果表明:针对黄瓜白粉病,使用常规药剂三唑酮已产生抗药性,各浓度翠贝、各浓度4%农抗120、高浓度世高、高浓度木醋液、高浓度多抗霉素均具有较好抑制效果。针对黄瓜灰霉病,扑海因对灰霉病菌的抑制效果最好,高浓度百菌清、高浓度益微菌剂(绿康微)防效次之。
To study the effect of several biological agents on the control of cucumber powdery mildew and gray mold disease and to find out the biological agents with better prevention and cure effects through the indoor prevention and control efficacy test so as to provide evidence for the cucumber field application. The results showed that: For the cucumber powdery mildew, the use of conventional drug triadimefon have been drug-resistant, the concentration of Triptolides, the concentration of 4% of agricultural anti-120, high concentrations of worldly high concentrations of wood vinegar, high concentrations of polyoxin All have better inhibitory effect. Botrytis cinerea against Botrytis cinerea for the best cucumber gray mold, high concentrations of chlorothalonil, high concentrations of micro-fungicide (Lvkang micro) control effect second.
