Growth of 13 F. graminearum isolates, 6 F. avenaceum isolates and 6 F. verticillioides isolates was analysed on potato-dextrose agar amended with 0.1, 0.33, 1, 3.3 and 10 mg l-1 of carbendazim, tebuconazole, flutriafol, metconazole, and prochloraz. Average concentration which reduced mycelial growth by 50% comparing it to control (EC50) was calculated for each isolate. Among fungicides tested, prochloraz was shown to be the most effective in growth inhibition of all three species, while flutirafol was proven to be the least effective.Metocnazole was more efficient in comparison with carbendazim and tebuconazole. EC50 values of all isolates on prochloraz were lower than 0.1 mg l-1, while on flutirafol they ranged between 1.66 and 8.51 mg l-1 for 18 isolates, or were higher than 10 mg l-1 for 7 isolates. EC50 values on carbendazim were 0.39-1.41 mg l-1 for F. graminearum isolates, 0.91-1.35 mg l-1 forF. avenaceum, and 0.47-0.6 mg l-1 for F. verticillioides. EC50 values on tebuconazole were 0.85-2.57 mg l-1 for F. graminearum, 0.85-1.58 mg l-1 for F. avenaceum and 0.22-0.85 mg l-1 for F. verticillioides,while on metconazole EC50 values ranged between less than 0.1 mg l-1 to 1.66, 0.56,and 0.17 mg l-1 for F. graminearum, F. avenaceum and F. verticillioides, respectively. Average growth inhibitions of different Fusarium species and all Fusarium isolates together on different concentrations of fungicides tested were significantly different. Significant differences in growth were not determined among isolates of the same species on neither one of fungicides tested, indicating that no decreased sensitivity to the fungicides exists among isolates included in the study. |
