摘要:

本研究旨在阐明江苏省草莓主产区草莓灰霉病菌种群对常用杀菌剂的敏感性。采用区分剂量法测定了2019和2020年采集的236株草莓灰霉病菌(Botrytis cinerea)对13种杀菌剂的抗性,并对菌株抗性频率和多药剂抗性进行了分析。结果表明:所有灰霉菌株对咯菌腈(fludioxonil,Flu)表现敏感,而对多菌灵(carbendazim,Car)、吡唑醚菌酯(pyraclostrobin,Pyra)、扑海因(iprodione,Ipr)、腐霉利(procymidone,Pro)、嘧霉胺(pyrimethanil,Pyr)产生了较高的抗药性,其抗性频率分别为58.05%、55.01%、51.44%、45.80%、33.94%;灰霉病菌种群在地区间对不同药剂的抗药性水平不同,溧水、昆山、姜堰、铜山田间以抗性菌株为优势种群,无锡和常州新北地区以敏感菌株为主;本研究在区分计量浓度下,根据各药剂抑菌率分布状况,将供试药剂分为敏感药剂、敏感性下降药剂和抗性药剂3种类型;本研究共检测到9种抗药性类型:PyraR(7.32%)、CarR(6.50%)、PyrR(0.81%)、CarR PyrR(3.25%)、CarRPyraR(14.63%)、CarRBosR(1.63%)、CarRPyraRPyrR(23.58%)、CarRBosRPyraR(7.31%)、CarRBosRPyraRPyrR(34.15%)。江苏省草莓灰霉病菌种群对多菌灵和吡唑醚菌酯基本丧失了敏感性,对扑海因、腐霉利、啶酰菌胺、戊唑醇等敏感性下降,多药剂抗药性种群以CarRPyraRPyrR和CarRBosRPyraR PyrR为主,抗性治理措施中推荐使用不同类型药剂交替防治灰霉病。

Abstract:

The purpose is to clarify the resistance level of Botrytis cinerea to common fungicides in main strawberry producing areas of Jiangsu Province. The resistance of 236 strains of Botrytis cinerea collected in 2019 and 2020 to 13 fungicides were measured by discriminative dose method, and the resistant frequency and multidrug resistance of the strains were analyzed. The results showed that all strains of Botrytis cinerea were sensitive to fludioxonil (Flu), but resistant to carbendazim (Car), pyraclostrobin (Pyra), iprodione (Ipr), procymidone (Pro), pyrimethanil (Pyr), and their resistant frequencies were 58.05%, 55.01%, 51.44%, 45.80%, and 33.94%, respectively. Strains of Botrytis cinerea had different resistance levels to different fungicides in different regions, the resistant strains were the dominant species in Lishui, Kunshan, Jiangyan and Tongshan, and the sensitive strains were the main species in Wuxi and Changzhou. According to the distribution of inhibitive rate of each fungicide, the tested fungicides were divided into three types: sensitive, sensitive decrease and resistant. A total of 9 resistant types were detected in this study, including PyraR(7.32%), CarR(6.50%), PyrR(0.81%), CarR PyrR (3.25%), CarR PyraR(14.63%), CarR BosR(1.63%), CarR PyraRPyrR (23.58%), CarRBosRPyraR(7.31%), and CarRBosRPyraRPyrR (34.15%). The Botrytis cinerea strains of strawberry in Jiangsu Province basically have lost sensitivity to carbendazim and pyraclostrobin, and are sensitive decrease to iprodione, procymidone, pyramidamide and tebuconazole. CarRPyraRPyrR and CarRBosRPyraR PyrR are the dominant populations. It is recommended to use different types of fungicides to control Botrytis cinerea alternately in the resistance management measures.
