| 摘 要： | 1.0 mg/L和5.0 mg/L多菌灵盐酸盐溶液处理灰霉病菌多菌灵敏感菌株和抗性菌丝体,用电导仪测定溶液电导率的动态变化,结果表明:在敏感菌株存在时,多菌灵盐酸盐溶液2 h后的电导率显著降低,而抗性菌株存在的溶液中电导率则未见下降。

| Abstract: | A carbendazim-susceptible isolate and a carbendazim-resistant isolate of Botrytis cinerea were compared with regard to mycelial growth and the extreme value of conductance upon treatment with the benzimidazole fungicide carbendazim hydrochloride. The result showed that the EC50 value of carbendazim-susceptible isolate was 0.062 0 mg/L, while the carbendazim-resistant isolate formed normal colony on PDA containing 1 000 mg/L carbendazim hydrochloride. Under the treatment of carbendazim hydrochloride with the concontration of 5 or 10 mg/L,the conductivity of carbendazim-sensitive isolate showed a decreasing tread,but that of carbendazim-resistant isolate only changed a little. |
