| 中文摘要: |
| 采用菌丝生长速率法测定了14种生物杀菌剂对人参灰霉病菌的室内毒力, 并进行了7种生物杀菌剂对人参灰霉病的田间药效试验。室内毒力测定结果表明:0.3%丁子香酚SL和2%蛇床子素EC对人参灰霉病菌毒力最强, 其EC50分别为0.129、0.623 mg/L, 2%春雷霉素AS等5种生物杀菌剂对人参灰霉病菌也具有较好的抑制效果, 其EC50在12.857~127.012 mg/L之间。田间试验结果表明:0.3%丁子香酚SL在田间对人参灰霉病表现较高的防效, 2%春雷霉素AS 和3%中生菌素WP次之。初步筛选出了对人参灰霉病具有较好防效的生物杀菌剂, 为人参灰霉病的安全防控提供科学依据。 |
| 英文摘要: |
| Toxicities of 14 biofungicides against Botrytis cinerea were tested by mycelium growth rate method in laboratory, and field trials of 7 biofungicides against grey mold of panax were also conducted. Indoor bioassay showed that 0.3% eugenol SL and 2% osthole EC had the best toxicity against B.cinerea with EC50 values of 0.129 and 0.623 mg/L, respectively. 2% kasugamycin AS and other four biofungicides also had toxicity to B.cinerea with EC50 values ranged from 12.857 mg/L to 127.012 mg/L. Field trials demonstrated that 0.3% eugenol SL exhibited high control effect, 2% kasugamycin AS and 3% zhongshengmycin WP followed. Thus, the effective biofungicides were screened out for the disease control. |
