摘要
室内采用离体叶段法检测了采自辽宁省7个市的53个稻瘟菌株对三环唑的敏感性。结果表明,该7个市的稻瘟病菌对三环唑未产生抗药性;初步确定所有菌株EC50的平均值0.4259mg/L为辽宁省稻瘟病菌对三环唑的敏感基线;最敏感的是丹东菌株和大连菌株,其EC50平均值分别为0.3412、0.3461mg/L,最不敏感的是本溪菌株和沈阳菌株,其EC50平均值分别为0.5171、0.4938mg/L。
The sensitivities of 53 Magnaporthe grisea isolates collected from 7 cities of Liaoning Province to tricyclazole were examined in vitro. The results indicated that there were no resistant isolates to tricyclazole in the 7 cities. The average EC500.4259 mg/L was the baseline-sensitivity of Magnaporthe grisea to tricyclazole. The most sensitive isolates were from Dandong and Dalian with ECs0 0.3412 and 0.3461 mg/L, the least sensitive ones were from Shenyang and Benxi with EC500.5171 and 0.493 8 mg/L respectively.
