Abstract:

The study aims to detect the species composition of Fusarium spp. in Jiangsu and the resistance severity to traditional fungicides. The ascospores of Fusarium spp. from Liyang, Tongzhou and Yancheng in Jiangsu Province were used as materials to identify its dominant species and detect the resistance to carbendazim, tebuconazole and prochloraz. The results showed that Fusarium asiaticum was detected in all Fusarium spp. strains in Jiangsu, it was the absolute dominant species; the proportion of Fusarium graminearum was the highest (14%) in Liyang, the lowest in Tongzhou (8%), the average proportion was 11.33%, significantly lower than the proportion of F. asiaticum; the resistance frequency of Fusarium spp. to carbendazim in Jiangsu was between 26.3% and 54.5%; no Fusarium spp. strain resistant to tebuconazole and prochloraz was detected. In summary, the dominant species of Fusarium spp. in Jiangsu is F. asiaticum, and it has developed strong resistance to single carbendazim, and no resistance to tebuconazole and prochloraz.
