REVUS^®

Q: What is the Mode of Action (MOA) of REVUS®?

REVUS® is a highly effective preventative fungicide that primarily inhibits germination of Downy Mildew, preventing penetration into the plant tissue.REVUS® contains the active constituent mandipro-pamid, which is a carboxylic acid amide fungicide. REVUS® and dimethomorph (Acrobat*) inhibit the biosynthesis of phospholipids and cell wall deposition.

Q: What is the MOA group for REVUS®?

REVUS® and Acrobat* belong to the Carboxylic Acid Amides fungicide Group, FRAC Group 40 (CAA-fungicides.)

Q: What is the resistance risk of REVUS®?

Long-term experience with CAA fungicides (REVUS® and Acrobat*) demonstrates that the resistance risk of Plasmopara viticola to this fungicide group is considered to be moderate and can be managed through appropriate use strategies.

Q: How rainfast is REVUS®?

Once dried on the plant, REVUS® cannot be washed off the plant (REVUS® LOK+FLO™ action) - unlike traditional protectants. REVUS® will remain LOK’ed on and FLO in to treated plant tissue to offer control of Downy Mildew, regardless of rainfall.

Q: Is REVUS® a systemic fungicide?

No, REVUS® has translaminar movement meaning it will move through treated plant tissue in a direct line from the site of application to the direct opposite side of the treated plant tissue. This offers protection on the underside of the leaf or the inside of the developing grape berry.

Q: Does capfall reduce the protection offered by REVUS® over this growth period?

The translaminar movement of REVUS® provides effective protection across both plant surfaces, and even under extreme weather conditions or when caps fall off during the flowering period, you can be reassured that REVUS® will move through the cap to protect the berry underneath the cap even after the cap has fallen off.

Q: How compatible is REVUS® with other products?

REVUS® is compatible with the following: THIOVIT JET®, TOPAS®, PROCLAIM®, AGRAL®, SWITCH®, Mimic*, Success*, Avatar*, Delfin Df*, Dithane Rainshield*, Kocide Blue Xtra*, Legend*, Oxydul Df*, Prosper*, Scala*, Teldor*.

REVUS^® fungicide has been used by viticulturalists for over ten years to control downy mildew (Plasmopara viticola). It has been the go-to fungicide for reasons beyond exceptional efficacy, such as residual activity, rainfastness and value for money.

REVUS^® fungicide highlights

Provides long-lasting protection against downy mildew in grapes, lettuce, leafy vegetables and poppies.
Unique LOK+FLO action with the active locking tightly to the waxy layer of the plant and translaminar flow into the leaf to give residual protection.
Rainfast once dry to deliver consistent and reliable disease control.
Flexibility of application without adverse impacts on pollinators for safe use within an IPM program.
Purchase in the Mildew Manager pack with MIRAVIS^® fungicide for use in grapevines and save over $6/ha.

Should REVUS® be tank-mixed with another MOA Downy Mildew protectant fungicide?

New resistance management guidelines state that in ‘high pressure regions’ REVUS^® should be mixed with a protectant fungicide from a different fungicide group. In such high risk areas a maximum of 4 REVUS^® sprays can be applied in a season so long as they are part of such a tank mix. In other low to medium risk areas a maximum of 2 solo sprays of REVUS^® can be used, with no more than 2 consecutive REVUS^® sprays being applied. REVUS^® should not be the final downy mildew spray for the season and the number of REVUS^® sprays should comprise no more than 50% of the total number of downy mildew sprays for the season.

Why are there two different rates of REVUS® on the label?

The two rates are on the label to provide growers with the flexibility to choose the protection period that they want to achieve, and also to suit the conditions at the time of application.

The 40mL/100L, Dilute application rate is designed for periods where rapid leaf growth is occurring and suits application intervals of 10-14 day intervals as part of a Downy Mildew control program applied prior to a Downy Mildew infection event.

The 60mL/100L, Dilute application rate is designed for periods when conditions are more conducive to Downy Mildew infection and a longer period of control is desired (10-21 day intervals), however, spray intervals of more than 14 days should only be used once significant new growth has ceased.

How rainfast is REVUS®?

Once dried on the plant, REVUS^® cannot be washed off the plant (REVUS^® LOK+FLO™ action) - unlike traditional protectants. REVUS^® will remain LOK’ed on and FLO in to treated plant tissue to offer control of Downy Mildew, regardless of rainfall.

No, REVUS^® has translaminar movement meaning it will move through treated plant tissue in a direct line from the site of application to the direct opposite side of the treated plant tissue. This offers protection on the underside of the leaf or the inside of the developing grape berry.

Is the new growth that occurs after a REVUS® application protected against Downy Mildew?

No. There is only one group of fungicide - products which contain phosphorous acid - which will move out of treated leaf through the petiole and into new growth. Fungicides which are labelled as being systemic are generally only either translaminar or xylem mobile, meaning they move in an outwards direction from the point of application.

Does capfall reduce the protection offered by REVUS® over this growth period?

The translaminar movement of REVUS^® provides effective protection across both plant surfaces, and even under extreme weather conditions or when caps fall off during the flowering period, you can be reassured that REVUS^® will move through the cap to protect the berry underneath the cap even after the cap has fallen off.

Do you need to add an adjuvant with REVUS®?

REVUS^® does not require the addition of a nonionic surfactant. However, where necessary for other compatible products, a non ionic surfactant may be used.
