Revystar approved for use on New Zealand barley and wheat

◼ New Zealand’s Ministry for Primary Industries approves Revystar®, BASF’s latest fungicide
◼ Available in spring 2020, Revystar is a co-formulation of the latest generation Group 3 triazole fungicide and a Group 7 SDHI fungicide
◼ Unique mode of action provides market-leading, broad-spectrum control of key diseases in cereals, including Ramularia leaf spot in barley

Revystar, an innovative, co-formulated fungicide with two modes of action, has been registered for use on New Zealand barley and wheat crops by the Ministry for Primary Industries. Set to become the new industry benchmark for disease control in barley and wheat, Revystar allows growers to confidently pursue optimal yields every season.

For New Zealand barley growers who have experienced years of difficulty in managing Ramularia leaf spot, Revystar will offer a welcome alternative to other fungicides which have declined in efficacy.

“Local trial results show Revystar as a stand-out performer against Ramularia,” said Grant Hagerty, Technical Manager Agricultural Solutions at BASF. “Because Ramularia is such a tricky disease to control, we expect Revystar will catch growers’ attention, and they will find it a beneficial addition to the overall rotation in both barley and wheat.”

Revystar’s uniqueness lies in its dual modes of action. It is a co-formulation of two active ingredients: mefentrifluconazole, a Group 3 triazole fungicide, branded as Revysol®, and fluxapyroxad, a Group 7 SDHI fungicide branded as Xemium®.

Due to its strong performance, Revystar will play a crucial role in future resistance management, offering New Zealand growers a highly effective tool to help them better protect their crops, manage resistance, and increase yield in a sustainable way.

“For years, local growers have needed new fungicidal chemistry to manage changes in the prevalence and severity of diseases as well as sensitivity swings – a form of resistance – in these diseases,” explained Hagerty. “Revysol, as a new active for New Zealand agriculture, affords excellent control of the two most at risk cereal pathogens, namely Ramularia leaf spot and Speckled leaf blotch. Revysol can control pathogens that have developed tolerance to older Group 3 triazole fungicides. That gives grain growers a degree of assurance that they can stay on top of both disease and resistance problems.”

Revystar will be available to growers in spring 2020. It is the latest addition to a long-running series of BASF innovations that is set to continue with several further product launches over the next few years.
