New fungicide well received by barley market last season

Miravis Flexi, a fourth-generation SDHI (Group 7) fungicide powered by the active ingredient Adepidyn technology, gained registration in New Zealand in March 2024 and was widely adopted in the barley market last season.

Ross McCallum, territory sales manager for Syngenta based in Ashburton, reports excellent feedback on this powerful and flexible formulation.

“The solo formulation of Miravis Flexi has been particularly appreciated,” he notes.
“It offers growers and field representatives the flexibility to choose the best fungicide mix partner for their specific conditions and needs.

“Growers understand that diseases such as Ramularia leaf spot and Scald can both cause significant yield losses if not properly controlled. The powerful, long-lasting and consistent control of these diseases was evident with Miravis Flexi this season.

Miravis Flexi has excellent compatibility with a range of other fungicides, herbicides, insecticides, and plant growth regulators tested in our comprehensive crop safety trials. This made my job easy to recommend different tank mix combinations, appropriate for any given situation, giving growers added peace of mind.”

Miravis Flexi can also be flexibly applied from GS32–49 depending on the disease risk present at the time. A minimum interval of 14 days must be observed if two consecutive applications are made.

Ross McCallum says it is also important that resistance management guidelines, designed to delay the onset of resistance, are strictly followed. Therefore, a maximum of two Miravis Flexi or any Group 7 SDHI fungicide applications should be made per season.

“Miravis Flexi should always be applied preventatively at a rate of 1.2 litres per hectare and in mixture with another approved, non-cross resistant fungicide recommended to control the same target diseases. The addition of an approved triazole fungicide is recommended,” he says.

Syngenta has a deep investment in the NZ cereal industry and provides excellent stewardship to the products registered in cereals. These include well-known brands Amistar, Elatus Plus, Moddus Evo and Twinax Xtra.

With continued industry support from growers and distributors, Syngenta looks forward to bringing new products to market in the future.

Growers are reminded that purchases of Miravis Flexi and other Syngenta products help them qualify for free nozzles.
