Some Principles of Fungicide Resistance (PPFS-MISC-02)

Fungicides are important tools in modern crop production. Unfortunately, one of the risks of using these products is that fungi sometimes develop resistance to them. 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.
