采用含毒介质法进行了13种杀菌剂对木薯细菌性枯萎病菌的室内毒力测定.结果表明,治农菌(2％三唑酮·30％乙蒜素EC),正萎舒(80％乙蒜素EC),农猎手(70％代森锰锌WP)和农用硫酸链霉素(72％硫酸链霉素SP)的最低有效浓度最小,抑菌效果最好.腈菌唑(12.5％腈菌唑SP),噻菌铜(20％噻菌铜SC)和抑阿(20％叶枯唑wP)的最低有效浓度最大,抑菌效果最差.2011年,在广东省湛江市进行了7种杀菌剂的田间试验,结果表明,中生菌素(3％中生菌素WP)、治农菌(2％三唑酮·30％乙蒜素EC)和正萎舒(80％乙蒜素EC)的防效较好,建议生产上使用.%13 bactericides were screened by toxic media method. 2% triadimefon 30% ethylicin EC, 80% ethylicin EC, 70% mancozeb WP and 72% strepolin SP were found to have the lowest effective concentration and best inhibitory effect. 12.5% myclobutanil SP, 20% thiodiazole-copper SC and 20% bismerthlazol WP were found to have the highest effective concentration but worst inhibitory effect. In 2011, several kinds of bactericides were evaluated in the cassava plantation of Zhanjiang, Guangdong. The results showed 3% zhongshengmycin W, 2% triadimefon 30% ethylicin EC and 80% ethylicin EC had good control effect and suggested to be used for field control.
