摘要 采用室内菌丝生长速率法测定了代森锰锌、百菌清、戊唑醇、甲基硫菌灵及咯菌腈5种杀菌剂对蓝莓枝枯病菌(Neofusicoccum parvum)的抑制作用,并对盆栽蓝莓和田间蓝莓植株进行了5种杀菌剂的药剂保护及治疗试验。室内毒力测定试验结果表明,代森锰锌、百菌清、戊唑醇、甲基硫菌灵及咯菌腈对蓝莓枝枯病菌菌丝生长均有一定的抑制作用,EC50值介于0.0515—4.1179mg/L,其中以咯菌腈的室内抑菌效果最佳。温室盆栽及田间药效试验结果表明,5种杀菌剂对蓝莓枝枯病均具有一定的预防效果,以百菌清及戊唑醇对枝条的保护效果较好,但对已经发病的枝条无治疗效果。因此,在田间生产中,应注重枝干伤口的保护,及时在修剪后喷施杀菌剂预防病原菌的侵染发生。
