摘　　要：采用生长速率法测定了纳他霉素对苹果轮纹病菌、苹果黑星病菌、苹果黑斑病菌、苹果腐烂病菌的室内毒力,结果表明,该制剂对各病菌的抑制有效中浓度EC50分别为18.44、49.43、32.08、29.87μg/mL,并用病原菌感染方法测定了制剂对贮运期苹果的实物防治效果。纳他霉素浓度为200μg/mL的制剂各处理组在10d、14d、18d的防效分别达到52.91%、55.02%、54.12%,显著高于多菌灵对照的防效。Toxicity of Natamycin to Botryosphaeria berengerianaf-sp. piricola, Venturia inaequalis （Cooke） Wint., Trictothecum roseum Link （Acremonium stictum Link）, Cytospora sp. was measured by growth rate test in laboratory, and the results showed that EC50 of the preparation to every disease fungi is 18.44, 49.43, 32.08 and 29.87μg/mL. And Natamycin preparation control effect on apple disease during transportation and store was mensurated by pathogeny infection method. Control effect of every treatment of 200μg/mL Natamycin after 10 d, 14 d and 18 d was 52.91%, 55.02% and 54.12% respectively, which is better than carbendazim significantly.
