摘　　要：室内生测结果表明，菜病清对低等病原菌具有显著杀灭作用，ＥＣ５０＜１００；最佳浓度４００～１２００倍；对高等病原菌具有抑制作用，是一种较广谱的防治蔬菜病害的药剂。田间药效试验表明，菜病清对黄瓜霜霉病、角斑病，番茄灰霉病，芹菜斑枯病等具有显著防治效果，稀释２００～４００倍，防病效果达８５％～９０％以上，综合防病增产效果优于目前常用的杀菌剂。The laboratory toxicity of Caibingqing was studied against 12 species of pathogens including tomato gray mold ( Botrytis cinerea ) etc. The results showed that the Caibingqing was a high efficiency fungicide with control humble pathogenic fungi. The results of the field tests showed that the Caibingqing has a superior function controlling for tomato gray mold, cucumber downy mildew and angular leaf spot, celery late blight etc. comparing with the fungicides utilized in controlling vegetable crops diseases.
