探讨了５０％果病清悬浮剂的不同配比组合在室内条件下对苹果黑星病的毒力评价，以及果病清对苹果黑星病、炭疽病等１２种蔬菜、果树的病原菌的毒力和有效浓度。试验结果表明，以杀菌毒力和共毒系数来评价果病清的复配组合应以２∶３（多菌灵∶成膜剂）比例最佳，该配比组合共毒系数为２８８．１１，ＥＣ５０＝６７．３μｇ／ｇ，增效作用显著。果病清对供试的１２种病原菌均具有显著的抑制作用，有效浓度为５６０～２９００倍，ＥＣ５０为５．８～１７７．７μｇ／ｇ．
To investigate the toxicity of different combinations of 50% MRSA in indoor conditions on apple scab, and to evaluate the virulence of MRS on 12 kinds of vegetables such as apple scab and anthracnose and the pathogen of fruit trees Force and effective concentration. The test results showed that the ratio of 2: 3 (carbendazim: film former) should be the best combination of fungicidal toxin and co-toxicity coefficient to evaluate the combination of fruit and vegetable. The combination coefficient of co-toxicity was 288.11 , EC50 = 67.3μg / g, synergistic effect was significant. Fruit disease clear on the test of the 12 kinds of pathogens have a significant inhibitory effect, the effective concentration of 560 to 2900 times, EC50 of 5.8 ~ 177.7μg / g.
