摘要:
以核桃黑斑病致病菌（Xanthomonas campestris pv.juglandis）为供试菌，采用分光光度计法，研究了8种杀菌剂及复配制剂对核桃黑斑病致病菌的药效，以期为园地核桃黑斑病的综合防治提供参考依据。结果表明：核桃黑斑病菌对不同供试杀菌剂的敏感性存在一定差异，其中对46.1%氢氧化铜SC，27.12%碱式硫酸铜SC和72%农用硫酸链霉素PX的敏感性最高，EC50值分别为0.492 2、0.704 0、0.764 3 μg?mL-1；对20%噻唑锌SC、20%噻菌铜 SC、47%春雷?王铜SC和保果灵复配及保果灵1号AS（白）的敏感性次之，EC50值介于1~4 μg?mL-1；对保果灵1号AS（褐）最不敏感，其EC50值为17.143 8 μg?mL-1。
Abstract:
Xanthomonas campestris pv.juglandis was used as test bacteria.The sensitivity of Xanthomonas campestris pv.juglandis to eight fungicides was tested by the spectrophotometer method in order to provide certain theoretical basis for the prevention and control of Xanthomonas campestris pv.juglandis in garden.The results showed that different fungicides displayed differences in the sensitivity on Xanthomonas campestris，while 46.1% copper hydroxide SC,27.12% copper carbonate SC and 72% streptomycin sulfate PX proved to be the most effective fungicide with EC50 values of 0.492 2，0.704 0,0.764 3 μg?mL-1 respectively.Followed by 20% Zn-thiodiazole SC,20% thifensulfuron-methyl SC,47% kasugamycin opperoxychloride SC，formulation Baoguoling No.1 AS and Baoguoling No.1 AS(white)，EC50 of which were 1-4 μg?mL-1.Baoguoling No.1 AS(brown) was the least sensitive with EC50 value of 17.143 8 μg?mL-1.
