Syngenta Ascernity- Gain a New Perspective on Large Patch Control and More
Ascernity fungicide combines an advanced SDHI and the proven cooling DMI to bring broad-spectrum disease control into focus. This innovative solution will prevent and give you long-lasting control of disease in your golf course turf.
Ascernity Offers Exceptional Disease Control and Large Patch Assurance
Ascernity fungicide combines SOLATENOL® technology (benzovindiflupyr) – an advanced SDHI for golf course turf – and difenoconazole, the proven cooling DMI, to prevent and control several key diseases in cool and warm-season turf, including large patch, brown patch, and anthracnose with no heat restrictions.

Large Patch Assurance & GreenTrust 365
The key to protecting your turf from large patch is through preventive fungicide applications. When you follow our large patch assurance program, you are guaranteed 90% large patch control on your treated turf, or Syngenta will provide product for a rescue treatment at no cost.*
In turfgrass, large patch disease is most common in the fall and spring as warm-season grasses enter or leave dormancy. Large patch is caused by the fungus Rhizoctonia solani strain AG 2-2LP. This disease can affect zoysiagrass, seashore paspalum, and occasionally bermudagrass.
Rhizoctonia solani, while present year-round in the thatch, soil, roots, and rhizomes, initiates infection when day length shortens and soil temperatures drop. Conditions that favor this disease include extended wet periods, high nitrogen levels, heavy soils, and dense thatch—disease symptoms can become severe to the point of turfgrass loss in the spring following green-up.
Now with Ascernity® fungicide, the GreenTrust 365 large patch assurance program, along with Heritage® and Headway® fungicides, provide industry-leading protection of warm-season fairways from large patch disease.
- Ascernity delivers longer residual on large patch than current industry standards and is now the cornerstone of the Syngenta Large Patch Prevention Assurance.
- Heritage provides industry-leading control of Rhizoctonia diseases and more than 25 other turfgrass pathogens while enhancing turfgrass health.
- Headway combines the power of Heritage with long-lasting protection in the soil and turfgrass crown provided by a proven DMI (Demethylation Inhibitor of sterol biosynthesis).

Ascernity may be applied as a foliar spray and integrated into a resistance management program. Thorough coverage is necessary to provide good disease control. For control of foliar diseases, allow Ascernity to dry completely before irrigating. For control of soil-borne diseases, Syngenta Ascernity can be watered in after application. All applications must be made according to the use directions on this label.
For resistance management, please note that Ascernity fungicide contains a Group 3 (difenoconazole) and a Group 7 (benzovindiflupyr) fungicide. Any fungal population may contain individuals naturally resistant to Ascernity and other Group 3 or Group 7 fungicides. A gradual or total loss of pest control may occur over time if these fungicides are used repeatedly on the same turf. Appropriate resistance management strategies should be followed.
To delay fungicide resistance, take one or more of the following steps:
- Rotate the use of Ascernity or other Group 3 and Group 7 fungicides within a growing season sequence with different groups that control the same pathogens.
- DO NOT make more than three sequential applications of Ascernity for control of powdery mildew.
- Use tank mixtures with fungicides from a different group that are equally effective on the target pest when such use is permitted. Use at least the minimum application rate as labeled by the manufacturer.
- Adopt an integrated disease management program for fungicide use that includes scouting, uses historical information related to pesticide use, and considers host plant resistance, the impact of environmental conditions on disease development, disease thresholds, as well as cultural, biological, and other chemical control practices.
- Where possible, make use of predictive disease models to effectively time fungicide applications. Note that using predictive models alone is not sufficient to manage resistance.
- Monitor treated fungal populations for resistance development.
