采用生长速率法对陕西省农业科学院新农药研究开发中心最新研制的高效、低毒防治蔬菜病害杀菌剂菜病清进行了室内毒力测定试验。结果表明，菜病清对辣椒疫霉病菌的增效系数为１７２．２１，明显大于１００，说明菜病清对辣椒疫霉病菌的毒效明显大于其有效成分单独使用时的毒效，增效作用显著。 The growth rate method was used to test the indoor virulence of the vegetable disease-killing and disinfecting agent with high efficiency and low toxicity developed by the New Pesticide Research and Development Center of Shaanxi Academy of Agricultural Sciences. The results showed that the synergistic coefficient of Lycopodium capsicum to Phytophthora capsici was 172.21, which was significantly higher than 100, indicating that the toxic effect of Lycoproctophthora capsici on Phytophthora capsici was significantly greater than that of its active ingredient alone Significant effect.
