With spring fast approaching and the spray season almost upon us, the AWRI encourages growers to review agrochemical stocks for use and safe disposal, based on the following:
- Agrochemical active ingredients recently reviewed by the APVMA for which “last use date” falls in the early part of the current 2025/26 growing season.
Diazinon – last permitted use date on grapevines is 10 September
Chlorpyrifos – last permitted use date on grapevines is 30 September - Highlighted changes to APVMA registration status for selected agrochemical products.
The products in the table below held active registration with the APVMA for use in Australian viticulture during the 2024/25 growing season, however ceased registration with the APVMA on 1 July 2025. These products now have a “last use date” of 30 June 2026.
