摘要
为了鉴定金叶女贞叶斑病的致病菌,寻找有效的防治药剂,通过组织分离法和形态学方法对引起金叶女贞叶斑病的病原菌进行了分离、纯化和鉴定,采用平皿菌丝生长抑制法测定了3种杀菌剂对该病原菌的抑制效果。结果表明:引起衡阳地区金叶女贞叶斑病的病原菌为蔓荆子棒孢(Corynespora viticis),50%多菌灵和75%百菌清对该病菌的生长有较好的抑制效果,EC50分别为1.782和2.080g·L-1,可作为该病的有效防治药剂。
In order to identify leaf spot pathogenic of Ligustrum vicaryi and find out effective pesticide to con- trol it,leaf spot pathogen was isolated, purified and identified using organizing separation and morphological method,then the inhibiting effect of three kinds of fungicides on the pathogen were studied by AGAR mycelia growth inhibition method. The results showed that pathogen isolated from Hengyang city was identified as Corynespora viticis,50% carbendazim and 75% chlorothalonil had better inhibition effects on it,EC50 were 1. 782 and 2. 080 g· L-1 respectively, which could be used.
