Crop(s):          Strawberry runner production.
Disease(s):     Powdery mildew (Podosphaera aphanus)

Resistance management strategy for:
*Group U6:       thiazolidine;
*Group 8:           hydroxy-(2-amino-) pyrimidines; and
*Group 13:         azanaphthalenes.

  1. Strawberry runner growers should also refer to the resistance management strategy for strawberry – powdery mildew, as it applies equally to strawberry runner growers. This strategy is for the additional range of compounds available to strawberry runner producers under permit.
  2. Fungicides from Group U6, 8 and 13 are available for use on strawberry runner crops under individual permits from the APVMA.
  3. Each permit states “DO NOT apply to fruit producing strawberry plants”
  4. Apply a maximum of two (2) Group U6 sprays per season.
  5. Apply a maximum of four (4) Group 8 or 13 sprays per season.
  6. Refer to individual permits for information relating to spray interval etc.

*Note: currently only available under temporary permit. Always check that permits are valid prior to use.

CropLife Australia’s Resistance Management Strategies provide a guide for crop protection product rotation through product groups. The strategies are a useful tool that supports farmers’ adoption of resistance management. All crop protection products must be handled and applied strictly as specified on the product label or APVMA permits.

These Resistance Management Strategies do not replace product labels. They are a guide only and do not endorse particular products, groups of products or cultural methods in terms of their performance. It is important to check with the Australian regulator’s (APVMA) product database for contemporary information on products and active constituents. The database can be sourced through
