[方法]采用菌丝生长抑制法,测定8种杀菌剂对3个不同多重抗药性番茄灰霉病菌株的生物活性,筛选防治番茄灰霉病高效低毒的杀菌剂,缓解和治理其多重抗药性。[结果]8种药剂中氟啶胺、咯菌腈与啶酰菌胺的抑菌效果最好,其次是氟吡菌酰胺、多氧霉素与丙烷脒抑菌效果较好,生防制剂丁子香酚与武夷菌素对多重抗药性番茄灰霉病菌也有抑菌作用。[结论]在农业生产中可以组合或轮换应用上述8种杀菌剂对多重抗药性番茄灰霉病进行防治。
[Method] The mycelial growth inhibition method was used to determine the biological activity of 8 fungicides against 3 different Botrytis cinerea strains. The fungicide for controlling Botrytis cinerea, Medicinal properties. [Result] The fungicidal effects of fluazinam, fludioxonil and boscalid were the best among the 8 drugs, followed by fluopyram, polyoxins and propamidine. The antibacterial agents Dingzi Eicosanol and Wuyiycin on the multi-resistant Botrytis cinerea also has antibacterial activity. [Conclusion] The multi-drug resistant Botrytis cinerea could be prevented and controlled by using 8 fungicides in combination or rotation in agricultural production.
