Some Principles Of Fungicide Resistance

   Fungicides are important tools in modern crop production. 

   Unfortunately, one of the risks of using fungicides is that fungi sometimes develop resistance to these products. Resistance development is a concern because the products may become less effective – or even useless – for controlling resistant pathogens and pests. This is a concern for all pesticides, including fungicides, insecticides, and herbicides. This fact sheet is intended to help pesticide applicators better understand this process.

   Some Principles of Fungicide Resistance (PPFS-MISC-02) is available online.
