Iprodione is registered with the Australian Pesticides and Veterinary Medicines Authority for control of botrytis bunch rot in grapes.
On 14 November 2017, a European Union decision was taken to withdraw authorisations for plant protection products containing iprodione as an active constituent. This ruling will come into effect before 5 March 2018.
This decision has resulted in uncertainty about the future tolerance for iprodione residues in wine destined for the European Union. It is recommended that wine-grape growers planning to apply products containing iprodione this season should contact their winery or grape purchaser prior to its use. The ‘Dog book’ recommendation has been changed to reflect this.
The latest version of the ‘Dog book’ can be viewed in the online pdf or mobile app available from the agrochemicals page on the AWRI website. For more information, please contact Marcel Essling on 08 8313 6600 or email helpdesk@awri.com.au.
