1. New active constituents
The following new active constituents are now registered by the Australian Pesticides and Veterinary Medicines Authority (APVMA) for use in winegrape production and are included in the ‘Dog book’ for the first time:
MANDIPROPAMID + OXATHIAPIPROLIN
APVMA product number 92989: Keybri Ultra fungicide is a Syngenta product registered for control of Downy Mildew in winegrapes. It is an activity group 40 + 49 fungicide.
Recommended export harvest interval (withholding period): Use no later than E-L 29, berries peppercorn size (not greater than 4mm diameter).
Note: Affinity Labs is working to include oxathiapiprolin in the agrochemical residue screen for vintage 2026.
ORANGE OIL
APVMA product number 89248: Prev-Am fungicide, miticide and insecticide is distributed by Rovensa ANZ and is registered in winegrapes for the control of bud mite and powdery mildew, and for the suppression of mealybug, scale and botrytis. It is an unclassified activity group product.
Recommended export harvest interval (withholding period): Use no later than 30 days before harvest.
2. Expanded Downy Mildew resistance management strategy
The CropLife Downy Mildew resistance management strategy has been expanded to include instructions for Group 40 + 49 given registration of this new activity group combination.
3. Correction
Trump Spray Oil was incorrectly listed under petroleum oil as a control for Powdery Mildew on page 8 and in the fungicide section of Table 2. This product has now been correctly listed in both places under paraffinic oil.
4. Change to winery restriction level
The winery restriction level for herbicide Katana 250 WG (flazasulfuron) in TABLE 2: Agrochemicals registered for use in Australian viticulture has been changed to ‘Restricted for use by some wineries. Contact your winery or grape purchaser prior to use.’ Note: this product has a 77-day withholding period for grapes.
5. Additional products added to existing active ingredients (see details below)
The following products have been added for existing active ingredients:
- Caribou insecticide (APVMA product number 96001, active methoxyfenozide) for control of Lightbrown Apple Moth on grapevines
- Chicane insecticide (APVMA product number 84630/148297, active emamectin) for control of Lightbrown Apple Moth and Grapevine Moth in grapes, except grapes grown for dried fruit production.
6. Removal of products

- Energise insecticide (APVMA product number 84630, active emamectin). Replaced by Chicane insecticide.
- Lepidex 500 insecticide (APVMA product number 33110, active trichlorfon). Product archived. Last use date was 30 June 2025, therefore existing stocks must be disposed of safely.
