| 摘 要： | 选用12.5%戊唑醇可湿性粉剂、80%代森锰锌可湿性粉剂、75%百菌清可湿性粉剂、22.7%二氢蒽醌悬浮剂、70%甲基托布津可湿性粉剂和25%丙环唑乳油6种杀菌剂对桉树焦枯病菌进行毒力测定试验,并用80%代森锰锌可湿性粉剂、75%百菌清可湿性粉剂和25%丙环唑乳油进行林地病害防治试验。结果表明,6种杀菌剂对桉树焦枯病菌菌丝生长均有抑制作用。戊唑醇的毒力最高,其EC50值为4.123 7 mg/L,其次是丙环唑,EC50值为68.052 8 mg/L,毒力最弱的是甲基托布津,EC50值为16 390.51 mg/L。代森锰锌、百菌清和丙环唑在浓度为1、5 mg/mL时,均可以完全抑制焦枯病菌产孢。施用代森锰锌、百菌清和丙环唑防治后,桉树林地病情指数分别比防治前下降了7.22%、15.53%、33.33%,对照区病情指数比防治前升高了28.33%。在病害发生之前施用代森锰锌或百菌清,可有效预防病害的发生,一旦桉树苗圃或幼林发生病害,立即施用丙环唑,可起到有效防治作用。
