The APVMA has issued an off-label permit enabling the use of a metalaxyl and mancozeb formulation on grapevines. It is essential that you read the conditions attached to the permit prior to use (View the full PDF).
NOTE: Chemical products applied to control Downy Mildew in viticulture must be registered by the APVMA and users must follow all label directions, unless a current off-label permit has been issued. Off-label use or the use of unregistered products have not undergone the relevant risk assessments and should not be used. Their use may be illegal, pose the risk of chemical residues in grapes, wine or have negative winemaking implications.
