摘要
通过对大棚黄瓜霜霉病和灰霉病的试验研究,分析比较不同药剂的药效,以确定恰当的防治方法。实验表明：使用20%嘧霉胺悬浮剂800-1000倍液、50%异菌脲可湿性粉剂750-1000倍液,在灰霉病发生初期使用效果极佳;使用58%甲霜锰锌可湿性粉剂、64%恶霜灵锰锌可湿性粉剂700倍液,在霜霉病发生初期和中期防治可达到理想效果。
Through a series of tests on greenhouse cucumber downy mildew and botrytis cinerea, analysis of comparative efficacy of different agents, and an appropriate control method was determined. Experimental result showed that： using 20% pyrimethanil SC 800-1000 times and 50% iprodione WP 750-1000 times, was better in the beginning of botrytis cinerea. Using 58% metalaxyl mancozeb WP and 64% iprodione WP 700 times liquid in disease early and mid treatment could achieve the desired effect.
