Abstract: To investigate the resistance of Gibberella fujikuroi collected from Jiangsu province to carbendazim, prochloraz and phenamacril as well as the cross-resistance of carbendazim and prochloraz to other fungicides, the resistance of 202 isolates of G.fujikuroi collected from 16 counties(cities) in Jiangsu province to carbendazim, prochloraz and phenamacril have been detected by using distinguishing dosage method, respectively, and then 10 isolates with different sensitivity to carbendazim and prochloraz were used for cross-resistance detection to tebuconazole,triticonazole, prothioconazole, metconazole,fludioxonil and fluazinam by using mycelium growth rate method,respectively. The results of resistance detection showed that the resistance frequency of G.fujikuroi collected from Jiangsu province to carbendazim, prochloraz and phenamacril were 77.72%, 67.33% and 0%, respectively. According to the resistance phenotypes of all isolates to 3 fungicides, 4 resistance types of G.fujikuroi have been identified.The isolates resistant to carbendazim and prochloraz and sensitive to phenamacril accounted for 58.42%, the isolates resistant to carbendazim and sensitive to prochloraz and phenamacril accounted for 20.30%, the isolates resistant to prochloraz and sensitive to carbendazim and phenamacril accounted for 9.90%, the isolates sensitive to carbendazim, prochloraz and phenamacril accounted for 11.39%. The results of sensitivity correlateon analysis showed that there were no positive-correlation across resistance between carbendazim and other fungicides as well as prochloraz and other fungicides. These results show that G.fujikuroi in Jiangsu province have relatively high resistance frequency to carbendazim and prochloraz, but were sensitive to phenamacril, and it’s need to select new fungicide to control rice bakanae disease.
