New fungicide offers wide fusarium head blight spray window

Syngenta recently rolled out Miravis, a brand new fungicide available for the 2020 growing season.

RealAgriculture’s Kara Oosterhuis caught up with Syngenta Canada’s Randy Retzlaff at the Crop Production Show at Saskatoon, Sask., to talk about Miravis Ace — a version of the fungicide that is targeted at spring wheat, winter wheat, and durum wheat.

Miravis Ace is aimed at protecting the crop from fusarium head blight (FHB), a devastating disease causing yield and quality losses.

“FHB can really affect the grower’s wheat crop in three different ways. It can reduce yield by producing a thin, shrivelled up kernel, so they have less grain to sell,” says Retzlaff. “Secondly, it can also reduce the grade of the grain by causing fusarium damage kernel percentage, and thirdly, depending on the severity it can cause a mycotoxin called DON, which can actually be harmful for human and animal use.”

The fungicide contains adepidyn molecule and propiconazol, which, according to Retzlaff, is what has managed the marketability of the product.

“Miravis Ace has been trialed over the past couple of years — over 85 trials in Western Canada — and we’re seeing on average a reduction of half of a per cent in fusarium damaged kernels and 15 per cent reduction in DON,” Retzlaff explains, adding “We all know that when you spray fusarium fungicide on wheat at anthesis it’s a very tight window. Miravis Ace can be sprayed from (bbch growth stage) 57 to 65, which is a wider window, and we’re seeing a consistent performance in the whole window.”
