摘要
为探明江苏省小麦赤霉病病菌对多菌灵抗药性变化,2012-2018年采集江苏不同地区赤霉病病菌菌株,系统监测江苏各地小麦赤霉病病菌抗药性频率。结果表明,江苏省小麦赤霉病病菌对多菌灵的抗药性频率呈上升趋势,2016年小麦赤霉病病菌对多菌灵抗药性频率最高,达44.7%,随后缓慢下降。鉴于多菌灵及其复配剂对江苏小麦赤霉病防控效果下降的实际,建议通过优选推广种植抗(耐)品种、加强农业管理、开展赤霉病病菌抗药性监测、大力推广新型高效杀菌剂等措施,延缓多菌灵抗药性发展。
To explore resistance development of Fusarium graminearum to carbendazim in Jiangsu province,strains of F.graminearum across the province were collected from 2012 to 2018,and the resistance frequencies were monitored.The results showed that resistance frequency of F.graminearum to carbendazim increased year by year from 2012 and reached 44.7%in 2016.In view of the fact that the efficacy of carbendazim and its mixtures against wheat scab have declined,several measures should be taken to alleviate resistance against Carbendazim,including choosing resistant wheat varieties,strengthening agricultural management,monitoring resistance development of F.graminearum and introducing new efficient fungicides.
