Abstract
- We determined minimal inhibitory concentration (MIC) of single active substances (a.s) of fungicides, twelve mixtures of two a.s and four a.s mixture. Additionally fractional inhibitory concentration index (FICI) of combined a.s. was calculated. Fungal and oomycete pathogens included Fusarium culmorum, Colletotrichum coccodes, Penicillium verrucosum, Sclerotinia sclerotiorum, Botrytis cinerea, Altemaria alternata, Aspergillus candidus, Monilinia fructicola, Septoria tritici and oomycete Phytophthora infestans. MIC were ranged from 0.1 μg/ml for fluazinam to 4954.5 μg/ml for cymoxaniL MIC of combined a.s were ranged from 0.00004 μg/ml for picoxystrobin+fenamidone to 4955 μg/ml for cymoxanil+ carboxin. Dodine+picoxystrobin had shown the most effective inhibitory and synergistic action against seven fungal or oomycete species (0.001 μg/ml- 35.9 μg/ml). The highest decrease of MIC values of dodine+picoxystrobin compared to their separate application indicate that these compounds should be considered to create novel commercial formulations offungicides.
