沈阳农业大学植物保护学院科研人员近期采用菌丝生长速率法测定了14种生物杀菌剂对人参灰霉病菌的室内毒力,并进行了7种生物杀菌剂对人参灰霉病的田间药效试验。室内毒力测定结果表明:0.3%丁子香酚可溶液剂和2%蛇床子素乳油对人参灰霉病菌毒力最强,其EC50分别为0.129、0.623mg/L,2%春雷霉素水剂、10%多抗霉素可湿性粉剂、3%中生菌素 Plant Protection College, Shenyang Agricultural University, researchers recently using mycelial growth rate method to determine the 14 kinds of biological fungicides Botrytis cinerea indoor toxicity, and 7 kinds of biocides on the gingivosa Botrytis in the field of efficacy trials . The results of indoor toxicity test showed that 0.3% eugenol solution and 2% osthole cream had the strongest virulence against Botrytis cinerea, with EC50 of 0.129,0.623mg / L, 2% of kasugamycin solution , 10% polyoxin anti-wettable powder, 3% mesotoxin
