Abstract: Potato dry rot by Fusarium solani is one of the most common and severe disease in storage. Laboratory toxicity of seven fungicides to this pathogen was tested with method of contained fungicide in medium and field control efficacy were determined by soaking inoculated potato with seven fungicides. In results, flusilazole and difenoconazole had the best inhibition effect with EC50 of 3.47 μg/m L、3.8 μg/m L. The second were Hymexazol, carbendazim and chlorothalonil with EC50 of 40.74 μg/m L, 70.79 μg/m L and 79.43 μg/m L. Thiophanate-methyl and iprodione had the lowest inhibition effect at EC50 of 436.5 μg/m L and 186.21 μg/m L. The field control efficacy of seven fungicides hymexazol, carbendazim,difenoconazole, flusilazole, chlorothalonil, thiophanate-methyl, and iprodione were 70%, 62.50%, 53.30%, 48.30%, 47.50%,43.70%, 12.50% respectively.
