Revus fungicide has been used by viticulturalists for over ten years to control downy mildew (Plasmopara viticola). In that time, it has been the go-to fungicide for reasons beyond exceptional efficacy, says Syngenta viticulture product lead Scott Mathew.
“Let’s take a look at why Revus fungicide is so good,” Mr Mathew said.
“Revus fungicide contains the active ingredient mandipropamid (Group 40). Upon application, Revus fungicide bonds quickly and strongly to the waxy layer of the leaf surface, locking to the leaf surface.
“It then has rapid translaminar movement through the plant to protect both sides of the leaf. This Lok + Flo action provides rapid rainfastness and is critical for effective disease control because downy mildew attacks the plant through the stomates on the undersides of the leaves.
“Revus fungicide specifically targets downy mildew by stopping spore germination and creates a barrier to prevent fungal penetration into the plant.
“Unlike traditional protectant fungicides like mancozeb and copper that can be washed off with rain, Revus fungicide is completely rainfast once the spray has dried,” Mr Mathew said. “Even under extreme weather conditions you can be reassured with the confidence of long-lasting protection of up to 21 days when used
at 60 mL/100L.
“Applied preventatively, Revus fungicide delivers excellent efficacy against downy mildew in high pressure situations, compared to other fungicides when applied at 21-day intervals.
“With downy mildew occurring in many viticultural regions last season, Revus fungicide delivered consistent and reliable disease control. Timely applications before a rain event offered growers long-lasting preventive protection against downy mildew, particularly when humid, wet conditions persisted during the growing season.”
To offer optimum protection of fruit, Mr Mathew said Revus fungicide should be applied at the critical period of flowering. It is important to follow the CropLife Resistance Management Strategy for downy mildew.
“Revus fungicide fits into a complete downy mildew program from Syngenta including, Bravo Weatherstik fungicide, Ridomil Gold Plus fungicide and Amistar 250 SC fungicide, delivering effective disease control and resistance management solutions.
“For a reliable, rainfast and long-lasting solution for both powdery and downy mildew protection, look no further than Miravis fungicide and Revus fungicide.”
Conveniently packaged in one box as Mildew Manager, this pack covers more than 30 hectares in one spray and provides a saving of over $6/ha when compared to buying the products separately (subject to the chosen water application volume).
“Not only does the Mildew Manager pack save money on the cost of the products, but it also saves time and the cost of an additional spray as these complementary products can be used together, which when applied prior to E-L19 can give you excellent downy and powdery mildew control through that critical flowering time period,” Mr Mathew said.
“Miravis and Revus fungicides represent the best-in-class management for downy and powdery mildew, providing protection for up to 21 days and with the Mildew Manager pack, it also represents exceptional value for money.”
