黄瓜霜霉病的药剂防治研究

Study on Chemical Control of Downy Mildew of Cucumber

为筛选防治黄瓜霜霉病的有效药剂,本文采用喷雾法对三种药剂的不同处理防治黄瓜霜霉病的药效进行了对比试验。试验结果表明,25%的甲霜·霜霉威可湿性粉剂300倍具有更高的防治效果,且对黄瓜安全,所以可以作为防治黄瓜霜霉病的理想药剂在生产上进行推广。

In the paper, to screen fungicides to control cucumber downy mildew, three fungicides were tested to control cucumber downy mildew by spray. The results showed that, 25% metalaxyl-propamocarb hydrochloride which was diluted 300 times had higher efficiencies control of cucumber downy mildew. It was also safe for cucumber. So it could be used as ideal fungicides on controlling cucumber downy mildew and could be extended in practice.
