American Midwestern wheat growers benefit from a wider application window with Syngenta’s Miravis® Ace fungicide

Date:05-04-2020

Growers looking for relief from Fusarium head blight can get a head start with Miravis^® Ace fungicide from Syngenta, according to performance results from 2019.

First available during the 2019 growing season, Miravis Ace widens the application window, allowing applications as early as 50% head emergence up to flowering. This flexibility, combined with proven disease control, helps maximize growers’ yield potential despite some of Mother Nature’s biggest threats.

“Miravis Ace definitely has an edge on any other product that's out there right now for Fusarium head scab control,” said Leslie Tanke, an agronomist in Miller, South Dakota. “With the issues we had in 2019, like weather and uneven emergence, Miravis Ace made it much simpler to feel confident in our head scab control. Our pollination window was so wide, and Miravis Ace covers that window much better than any other Fusarium control product out there.”

Miravis Ace is a convenient premix that combines propiconazole and Adepidyn^® technology – the first and only molecule with an SDHI mode of action available for head scab control. The fungicide enables growers to:
- Make on-time head scab applications and cover more acres
- Maximize yield by protecting the main heads and tillers
- Better preserve grain quality


“Head scab pressure can vary quite a bit region to region depending on the weather, so it can be difficult to predict,” said Nathan Popiel, Syngenta agronomy service representative in North Dakota. “Miravis Ace is a valuable tool for growers going into 2020 because it gives them more time to protect their crops and boost potential yield.”

Multiple years of Syngenta and third-party field trials have confirmed the ability of Miravis Ace to protect wheat yield and quality when applied early and at flowering. Data from 2018-2019 across the Midwest demonstrated that fields treated with Miravis Ace yielded an average of 12 bushels per acre (bu/A) more than untreated acres¹.

Additionally, 13 out of 15 field trials in 2018 that compared Miravis Ace to older fungicides showed improved disease control and yield results². Specifically:
- At 50% head-emergence timing³, Miravis Ace averaged 77.2 bu/A and a deoxynivalenol (DON) level of 3.1, compared to 71.6 bu/A and a DON level of 5 with a competitive fungicide
- At flowering timing, Miravis Ace averaged 78 bu/A and a DON level of 2, compared to 73.5 bu/A and a DON level of 2.4 with a competitive fungicide

“For the pressure we had, the disease control was very good,” Tanke said. “Miravis Ace exceeded my expectations, and it will be my go-to product if scab protection is needed.”

¹ Average of 22 trials in IL, MO, OH, SD, WI applied at Feekes 10.51, 2018-2019.
² FAD150A3-2018US. All trials resulted in statistically significant differences between treatments. Fifteen trials across 11 states.
³ Competitive products may not be labeled for use at 50% head emergence, and no recommendation or suggestion for use at this timing is being made. Data is intended solely for comparison at this application timing with Miravis Ace, which is labeled for use as early as 50% head emergence.
