It is important to use multiple fungicide modes of action (MOAs) to effectively manage your fields to combat or prevent a fungicide resistance problem on your farm. This lookup tool helps you to quickly identify the MOA of popular fungicide brands you may be using or considering. Because it is important to use diverse MOAs, the tool will also provide a list of products with the same MOA that won’t provide the diversification recommended.
