Adepidyn Overview

What is Adepidyn fungicide?

Adepidyn fungicide, the SDHI component in Miravis Ace, was designed for increased spectrum, power and stamina. This means that it provides highly potent, lasting disease control for greater protection from difficult diseases and improved application flexibility.

What sets Adepidyn fungicide apart from other fungicides currently on the market?

Adepidyn fungicide is a powerful active ingredient within the carboxamide class of chemistry with an SDHI mode of action. It is the only SDHI product available for Fusarium head scab control.

Adepidyn fungicide has excellent affinity for plant surfaces. It penetrates quickly and creates a reservoir of active ingredient within the plant for even distribution and improved stamina.

In addition, Adepidyn fungicide moves through the xylem within the plant to protect both the primary heads and tillers, which grow at varying rates.

Miravis Ace Overview

What is Miravis Ace fungicide?

Miravis Ace is a preventive and curative fungicide, containing Adepidyn fungicide and propiconazole.

The SDHI component within Miravis Ace is the first new mode of action introduced for Fusarium head scab control in several years. In addition to Fusarium head scab, Miravis Ace provides superior curative control of Septoria leaf spot.

With potent, long-lasting activity, Miravis Ace allows growers to experience less stress by allowing them to treat for head scab as early as 50% head emergence without sacrificing control or yield.

Application timing: 50% head emergence¹
Location: Lanexa, VA 2017
Disease shown: Fusarium head scab

¹ Prosaro is not labeled for use at 50 percent head emergence, and no recommendation or suggestion for use at this timing is being made. Photo is intended solely for comparison at this application timing with Miravis Ace, which is labeled for use as early as 50 percent head emergence.

Fusarium Head Blight Application Timing

Other Fusarium head scab control options leave no room for error, requiring applications to be made at flowering within a restrictive window that can be as short as 1 to 3 days. Missing this window, by applying too early or too late, decreases the efficacy of current fungicides to the point of near ineffectiveness.

Additionally, the restrictive application window required by other products forces growers to choose to protect either the primary heads or the tillers, resulting in sacrificed yield in one area or the other.

Miravis Ace Application Timing

Unlike competitive fungicides, Miravis Ace allows for application as early as 50% head emergence. This longer and more flexible application window enables growers and applicators to make Fusarium head scab applications on-time and maximize protection of the main head and tillers without sacrificing efficacy, yield or grain quality.

Superior residual provides greater flexibility and freedom from stress for growers and applicators who will be able to more accurately plan and manage disease.

Miravis Ace Application Timing

Performance at 50% Head Emergence and Flowering¹

Miravis Ace applications at 50% head emergence were just as effective as applications at flowering, resulting in decreased DON levels compared to existing market standards.

Increased Yields with Miravis Ace Applied at 50% Head Emergence and Flowering

In terms of yield, Miravis Ace applications at 50% head emergence were better than Prosaro^® applications at both 50% head emergence and flowering¹. On average, Miravis Ace improved yield an average of 10.8 bu/A over untreated².
