Revus has been granted registration by the Australian Pesticides and Veterinary Medicines Authority (APVMA) for control of Downy Mildew in grapevines.
Revus is a Syngenta Crop Protection Pty Ltd product. It contains the active constituent mandipropamid which is a Group 40 fungicide.
Resistance management strategy: DO NOT apply more than 3 sprays of Revus per season. DO NOT apply more than 2 sequential sprays of Revus alone before applying at least the same number of sprays from a different resistance group. DO NOT make Revus alone the last spray of the season.
Restriction on use for export grapes: Use no later than E-L growth stage 26 (cap-fall complete).
Mealybugs are not normally considered to be a significant pest in wine grapes. Conventional thinking is that numbers will be kept in check by a diverse range of natural enemies unless something (such as the use of a broad spectrum insecticide) disrupts these populations. If mealybugs are infesting wine grapes and causing significant damage, it is worth considering what may have interrupted the natural balance.
The table below provides a guide to all registered chemical options for mealybugs. Check the product label for appropriate use in your vineyard as registrations vary between states and between mealybug species.
It is recommended that you contact your winery or grape purchaser prior to any 1B insecticide application.
