Introducing RevyPro: The latest Revysol-containing fungicide

RevyPro builds on the proven strength of Revysol, bringing excellent efficacy on a broad spectrum of diseases, and boosting yields across both wheat and barley, BASF says. RevyPro joins Revystar XE as a Revysol-containing option in 2025. 

Formulation benefits

RevyPro contains 50g/litre Revysol (mefentrifluconazole), and 100g/litre prothioconazole. The active ingredients are uniquely formulated together as RevyPro and show a complementary interaction, producing performance beyond what would be expected. This has a positive impact on disease control and yield.

Rebecca Joynt, senior plant pathologist, ADAS said: “Our trials have shown that RevyPro can be used across the programme. It has good broad-spectrum activity and will certainly help disease control. 

“Over the last two years, ADAS has undertaken matrix design trials in wheat which has allowed us to compare RevyPro with its component straight actives, Myresa (97g/litre of Revysol) and Decoy (250g/litre). These trials are carried out at a single spray timing, putting the products under high levels of disease pressure.

“We found there appeared to be a slight formulation benefit, with the RevyPro formulation giving greater control of septoria, and higher yields than the equivalent tank mix.”

Jared Bonner, business development manager at BASF said: “RevyPro’s unique formulation enables fast foliar uptake meaning even with the increasingly variable weather conditions we are experiencing it can be relied upon. This will give growers greater confidence if the weather deteriorates after application. This rapid uptake gives good rainfastness and protection from UV light degradation.”

The fungicidal activity of prothioconazole occurs when it is activated, a process which only occurs inside the plant. Jared explained: “RevyPro’s fast uptake, quicker than comparable prothioconazole products, leads to higher levels of fungicidal activity, giving enhanced efficacy.”

Once inside the leaf, the Revysol component of RevyPro forms reservoirs allowing slow but consistent distribution of fungicide along the leaf length which helps with long term protection.

RevyPro is approved for use on all cereals except oats and offers growers flexibility with application timing, dose rate and mix partners when building their fungicide programmes.

RevyPro in wheat

ADAS carried out trials looking at RevyPro and different mix partners.

Rebecca Joynt commented: “The majority of our work with mixture partners was done using fenpicoxamid. When we compared 1-litre/ha fenpicoxamid + 1-litre/ha RevyPro to 1.25-litre/ha Univoq (fenpicoxamid + prothioconazole) we found that the fenpicoxamid + RevyPro treatment gave a reduction in septoria and in some places a yield response associated with that, compared to the Univoq treatment.”

Jared Bonner said: “RevyPro is a brilliant mix partner in wheat, providing excellent flexibility to the fungicide programme. When used in mixes RevyPro boosts the level of disease control and enhances the performance of the mix partner it is used with. This allows growers to be flexible with dose rates. RevyPro’s efficacy enables lower doses to be used of new innovative partner products whilst keeping performance levels the same or better.”

Different modes of action

When targeting septoria, RevyPro must be mixed with a fungicide from another mode of action in line with standard resistance management protocols.

Rebecca Joynt said: “Adding in the more active azole, Revysol, and including a range of products with different modes of action is the best strategy both in terms of disease control and for resistance management.”

Jared Bonner added: “The mixture of RevyPro helps reduce the selection of resistance to both azoles and because Revysol is a lower risk mode of action with high efficacy it is very good at protecting other actives. From a resistance management point of view you need to have Revysol somewhere within that programme to protect other higher risk modes of action.

“RevyPro enables growers to get good efficacy, good control and stewardship on the back of it.”

RevyPro in barley

RevyPro provides a new and flexible solution for barley, providing the ideal azole combination for this crop. RevyPro provides well balanced disease control covering all major barley diseases; net blotch, rhynchosporium, rust and ramularia.

David Leahy, business development manager at BASF said: “RevyPro is a fantastic new addition to our suite of barley fungicides. Its flexibility means it can be used either at T1 or T2 as a standalone product, with rates in the range of 0.75–1.0-litres/ha or it can be mixed with SDHIs or strobilurins if a grower is facing a particular disease situation. RevyPro can also be used on malting barley crops, up to and including flowering.

The unique formulation of RevyPro allows rapid uptake into the plant enabling excellent control on some of the key diseases in barley.”
