Abstract

Colletotrichum gloeosporioides species complex (CGSC) is the major pathogen causing strawberry anthracnose in Taiwan. Benzimidazoles and strobilurins are common fungicides used to control strawberry anthracnose. A total of 108 CGSC isolates were collected from five major strawberry-producing areas in Taiwan. The half-maximal effective concentration (EC50) values of most CGSC isolates for benomyl (59 isolates), carbendazim (70 isolates), and thiabendazole (63 isolates) were higher than 500 µg a.i./mL. Strobilurin tests showed that the EC50 values of most CGSC isolates for azoxystrobin (66 isolates), kresoxim-methyl (42 isolates), and trifloxystrobin (56 isolates) were higher than 500 µg a.i./mL. However, most CGSC isolates were sensitive to pyraclostrobin at 100 µg a.i./mL. Fungicide tests indicated that CGSC isolates show multi-resistance to benzimidazoles and strobilurins. Benzimidazole-resistant isolates were associated with a point mutation in codon 198 of the β-tubulin gene, and strobilurin-resistant isolates did not correspond with mutation in the cyt b gene or alternative oxidase activity.

台湾草莓炭疽菌菌种复合物对苯并咪唑和strobilurin的敏感性。
炭疽菌是台湾草莓炭疽病的主要病原菌。苯并咪唑和间苯脲是常用的杀真菌剂,用于控制草莓炭疽病。从台湾5个主要草莓产区共采集到108株CGSC分离株。大多数CGSC菌株对苯甲酰(59株)、多菌灵(70株)和噻苯达唑(63株)的半最大有效浓度(EC50)值均大于500µg a.i./mL。Strobilurin试验结果显示,大多数CGSC菌株对偶氮氧虫酯(66株)、甲基克雷索辛(42株)和三氯虫酯(56株)的EC50值均大于500µg a.i./mL。然而,大多数CGSC分离株对100 μ g a.i./mL pyraclostrobin敏感。杀菌剂试验表明,CGSC菌株对苯并咪唑类和异脲类具有多重抗性。苯并咪唑耐药菌株与β-微管蛋白基因密码子198的点突变有关,而strobilurin耐药菌株与cyt - b基因或替代氧化酶活性的突变无关。
