福建省番茄灰霉病菌对氟啶胺敏感基线建立及与不同杀菌剂的交互抗性
Baseline sensitivity ofBotrytis cinerea to fluazinam and cross-resistance to different fungicides in Fujian province
摘要
Abstract
To evaluate the sensitivity ofBotrytis cinerea to fluazinam and the existed cross-resistance between fluazinam and other fungicides, 106 single spore isolates ofB. cinerea were collected from tomato in Fujian province. The sensitivities ofB. cinerea isolates to fluazinam were determined by mycelial growth rate test. The results showed that EC50 values of 106 isolates to fluazinam followed a unimodal curve, ranging from 0.003 7 to 0.045 2 μg/mL with the mean EC50 value of (0.022 1 ± 0.009 8) μg/mL. Thus, the data could be employed as the baseline-sensitivity ofB. cinerea to fluazinam which could be used for the field resistance monitoring. And the sensitivities of 15 isolates ofB.cinerea, which exhibited different sensitivities to fluazinam, to pyrimethanil, iprodione, procymidone and picoxystrobin, were also tested with the mycelial growth rate method. The mycelial growth inhibition rates of the above mentioned 5 fungicides were fluazinam> iprodione> procymidone>picoxystrobin> pyrimethanil. No cross-resistance between fluazinam and other 4 fungicides was observed.关键词
