| 摘 要： | 目的]人参是我国传统名贵中药材,锈腐病是人参主要根部病害,生产上缺乏防治该病的有效药剂。本文对长白山区人参锈腐病发生危害进行调查,并选用新型杀菌剂对人参锈腐病菌的毒力及田间防效进行了测试,以期为生产上安全高效防治该病提供理论依据。方法]采用菌丝生长速率法测定11种杀菌剂对人参锈腐病菌的毒力,并进行田间防效试验。结果]室内毒力测定结果表明10%世高WG、18.7%凯特WG和60%百泰WG对人参锈腐病菌毒力最强,其EC50值分别为1.19mg/L、20.56 mg/L和27.77 mg/L。田间试验结果表明10%世高WG、18.7%凯特WG和60%百泰WG对人参锈腐病防效达50%以上。结论]人参锈腐病发病盛期为6月上旬至7月下旬,10%世高WG、18.7%凯特WG和60%百泰WG是目前防治人参锈腐病的有效药剂。

Toxicity Test and Field Control Effects of 11 New Fungicides against Cylindrocarpon destructans |
| |
| Abstract: | Aims] Ginseng as a valuable Chinese herbal medicine, rust rot is one of the major root disease of ginseng, based on lack of effective fungicides to control ginseng rust rot caused by Cylindrocarpon destructans in ginseng production, the aim of this research is to provide a theoretical basis for controlling ginseng rust rot. Methods] Toxicities of 11 fungicides against C. destructans were tested by mycelium growth rate method in laboratory, and field trials against C. destructans were also conducted. Results] The results indicated in laboratory that 10%score WG, 18.7?brio team WG and 60?itai WG showed higher effective to the C. destructans, Their EC50 values were 1.19mg/L, 20.56 mg/L and 27.77 mg/L. The results of field trials indicated that 10%score WG, 18.7?brioteam WG and 60?itai WG exhibited high control effect. Conclusions] Currently 10%score WG, 18.7?brio team WG and 60?itai WG are effective fungicides on ginseng rust rot. |
