Fungicide Families or Groups

Latest revision:

March 2024

A grower should use fungicides with different modes of action. Tank-mix or rotate materials found in different fungicide families or groups to prevent or delay the development of resistant fungi. Groups below are not arranged in alphabetical order or in numerical order by group. In general, the first few groups are active on Botrytis and similar fungi (Groups 1, 2, 12, 9, 17 and 7). The next few groups are active on oomycetes (groups 4, P7, 40, 49, 22, 27, 28 and 43). Groups 3, 5, 11, U6, 50 and 13 are active on powdery mildews and many other fungi. The rest of the groups have multisite activity and make good mixing partners depending on the disease in question.

Use pesticides safely!

Wear protective clothing and safety devices as recommended on the label. Bathe or shower after each use.
Read the pesticide label—even if you’ve used the pesticide before. Follow closely the instructions on the label (and any other directions you have).
Be cautious when you apply pesticides. Know your legal responsibility as a pesticide applicator. You may be liable for injury or damage resulting from pesticide use.

Trade-name products and services are mentioned as illustrations only. This does not mean that the participating Extension Services endorse these products and services or that they intend to discriminate against products and services not mentioned.

H - Home garden packaging commonly available. O - Acceptable in organic production.
