Tebuconazole-resistant Colletotrichum siamense isolates are defective in mycelial growth and conidiation. a Mycelial growth of the tebuconazole-sensitive and tebuconazole-resistant isolates of C. siamense on PDA medium after 5 days of incubation at 25 °C in the dark. b Column diagram showing colony diameters of the tebuconazole-sensitive and tebuconazole-resistant isolates of C. siamense on PDA medium after 5 days of incubation at 25 °C. Error bars denote the standard deviations from three repeats. Different letters indicate significant differences according to the Fisher’s LSD test at P = 0.05. c Conidial morphology of the tebuconazole-sensitive and tebuconazole-resistant isolates of C. siamense. Bar = 20 µm. d Conidiation capacity of the tebuconazole-sensitive and tebuconazole-resistant isolates of C. siamense. Conidial production was quantified after incubation in 30 mL PDB medium for 5 days at 25 °C. Error bars denote the standard deviations from three repeats. Different letters indicate significant differences according to the Fisher’s LSD test at P = 0.05
