This study aimed to clarify the sensitivity and cross-resistance of Botrytis cinerea on strawberries to fluazinam (FAN), boscalid (BCI) and phenazine-1-carboxylic acid (PCA) to guide the rational use of these drugs. By measuring the mycelial growth rate, the sensitivity of 126 strains of B. cinerea on strawberries to FAN, BCI and PCA in 9 regions of Hunan Province was determined. The results showed that highest half maximal effective concentration (EC50) values for FAN, BCI and PCA against B. cinerea on strawberries were 0.9840 mu g/mL, 9.0564 mu g/mL and 11.2239 mu g/mL, respectively; the min...
