Barley & wheat fungicide approved for use this spring

Published on 09/10/2020

Set to become the new industry benchmark for disease control in barley and wheat, Revystar allows growers to confidently pursue optimal yields every season, manufacturer BASF says. For NZ barley growers who have experienced years of difficulty in managing Ramularia leaf spot, it offers a welcome alternative to other fungicides which have declined in efficacy.

“Local trial results show Revystar as a stand-out performer against Ramularia,” says Grant Hagerty, technical manager agricultural solutions at BASF. “Because it 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, Hagerty says, offering NZ 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 resist-ance – in these diseases,” he explains. “Revysol, as a new active for NZ agriculture, affords excellent control of the two most at risk cereal pathogens, namely Ramularia leafspot and Speckled leaf blotch. It 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-runningseries of BASF innovations that is set to continue with several further product launches over the next few years.
