Take all Fusarium suppression Not a stand alone product for these diseases Fungicide resistance Some fungicides are site specific in their mode of action This means that it takes very little genetic change on the part of a fungus for resistance to occur Resistance may result in poor disease control or control failure Resistance may develop suddenly or gradually depending on the chemical involved Once resistance has developed in a fungal population it may last for a long time or gradually disappear if the fungicide is no longer used depending on the chemical Resistance is common for some diseases but not observed for others Fungicide resistance has been documented for anthracnose dollar spot Fusarium patch and Pythium blight The best strategy is to try to prevent or at least delay resistance The penetrant fungicides are all at risk for resistance Contact protectant fungicides are unlikely to result in resistance because they have multi site
