Syngenta’s Ascernity fungicide registered for use on turf in California

Ascernity fungicide, designed to deliver control of diseases like anthracnose, large patch and gray leaf spot in warm- and cool-season turf, is now registered for use on golf courses in California. The fungicide launched in the United States in July 2020.

“It’s exciting to finally receive the registration of Ascernity in California after several years of testing on turf,” said Dean Mosdell, Ph.D., technical services manager for Syngenta. “Ascernity adds a powerful tool to our disease control programs for cool- and warm-season turf in California.”

Ascernity combines SDHI Solatenol technology (benzovindiflupyr) with difenoconazole, the cooling DMI, to bring broad-spectrum disease control into focus. 

Ascernity is also designed to provide superintendents control of diseases like summer patch, brown ring patch, microdochium patch and dollar spot among others, plus suppression of rapid blight under a 2(ee) label. There are no heat restrictions and is the cornerstone of the GreenTrust 365 Large Patch Assurance Program. 

“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.”
