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 results of indoor bioassay showed that Caenqing had a significant killing effect on lower pathogenic bacteria with an EC50 <100; the optimal concentration was 400 ~ 1200 times; it had an inhibitory effect on higher pathogenic bacteria and was a relatively broad-spectrum agent for controlling vegetable diseases . The results of field trials showed that Cui Qingqing had significant control effects on cucumber downy mildew, angular leaf spot, tomato gray mold and spot blotch of celery, diluted 200 ~ 400 times, with the preventive effect of over 85% ~ 90% , The comprehensive disease prevention and yield increase effect is better than the currently used fungicides.
