采用离体抑菌圈法测定了6种杀菌剂对当归水烂病的毒力，结果表明，77%氢氧化铜可湿性粉剂320 ug/mL、30%扫细（琥胶肥酸铜）悬浮剂200、400 ug/mL和85%三氯异氰尿酸可溶性粉剂20、40 ug/mL的抑菌圈直径均>2.0 cm，具有良好的抑菌效果。在试验浓度范围内，各药剂随着浓度的提高对病菌的抑制作用增强。田间防效试验结果显示，77%氢氧化铜可湿性粉剂2.50、3.00 g/L浸根处理的防治效果分别达到78%和88%，其它3种药剂处理防效较低。

In this paper, six kinds of fungicides on the Angelica water rot virulence was determined by using indoor vitro inhibition zone way. The results showed that it has a good antibacterial effect, the inhibition zone diameter was higher than 2.0 cm which 77%of copper hydroxide WP 320 ug/mL, 30%sweep fine(amber plastic fertilizer acid copper) SC 200、400 ug/mL, and 85%TCCA soluble powder 20、 40 ug/mL . In the experimental concentration range, the concentration of bacteria inhibition enhanced with various chemical treatments significantly increase. At the same time, the field efficiency test results showed that 77%copper hydroxide WP 2.50,3.00 g/L soaking seedling treatment control effect reached 78%and 88%, other three kinds of various concentrations of drug control effect were generally low.
