California OK's Syngenta's Ascernity fungicide


Ascernity fungicide from Syngenta has been approved by the Department of Environmental Quality for use in California.

Launched in July 2020, Ascernity combines the advanced SDHI Solatenol technology (benzovindiflupyr) with a DMI (difenoconazole), the proven cooling DMI, to bring broad-spectrum disease control into focus. It is labeled for control of anthracnose, large patch, gray leaf spot and more in warm- and cool-season turf. Syngenta launched this dual-action fungicide in the United States in 2020.

Ascernity offers long-lasting control as the cornerstone of the GreenTrust 365 Large Patch Assurance Program and is safe to use on turf with no heat restrictions even in the summer when disease pressure is high.

For resistance management and broad-spectrum disease control, the Syngenta technical services team has developed agronomic programs that strategically rotate Ascernity with other trusted products. To find recommendations for incorporating Ascernity into an existing agronomic program, visit GreenCastOnline.com/Programs.

“We saw amazing results with Ascernity in our trials in Northern California,” said Jim Baird, Ph.D., turfgrass specialist, University of California, Riverside. “Ascernity was not only combative against anthracnose and rapid blight, but also restored overall turf health. We saw perfect turf in those plots surrounded by disease in the untreated areas.”

To help superintendents in California and across the country learn about Ascernity, Syngenta is launching the #Time4Ascernity Video Challenge. To qualify, participants must watch two of six videos at GreenCastOnline.com/AscernityChallenge from April 26 to May 26, 2021. Each video will feature customers and/or leading industry researchers discussing their experiences using Ascernity to control key turf diseases. Upon completion of an entry form, participants will be entered for a chance to win one of 50 randomly awarded KOOZIE Kamp hammocks.
