Syngenta launches two new fungicides

Posterity and Secure Action both target dollar spot, along with other turfgrass diseases.


Syngenta has launched two new fungicides for the turf market, Posterity and Secure Action, which the company says deliver proven, long-lasting control of dollar spot as well as other common turf diseases.

Posterity, which Syngenta calls the most-active SDHI in the turf market, provides long-lasting dollar spot control, holding strong for up to 28 days. Additionally, it delivers robust and consistent control of spring dead spot and fairy ring. It’s a solid rotation partner for agronomic programs to protect cool- and warm-season turf.

“Posterity was engineered to uniquely provide power and endurance, when controlling key diseases,” says Steve Dorer, fungicide brand manager for turf at Syngenta. “It was designed for greater affinity to binding sites in the pathogen, to provide more consistent control that superintendents need for these common but tough-to-control diseases.”

According to the company, Secure Action includes a boost of acibenzolar-S-methyl (ASM) to further improve golf’s leading multi-site contact fungicide, Secure. Secure Action helps condition turf, so it performs at its best during the season and quickly recovers from biotic stress, like dollar spot, and abiotic stress, like drought and heat. The enhanced formulation provides increased disease control — including a 21-day interval for dollar spot control and suppression of bacterial wilt.

“With the addition of ASM, Secure Action kick-starts the plant’s natural defenses for increased disease control and overall turf quality,” explains Mike Agnew, technical services manager for turf at Syngenta. “Research has shown that ASM works best when used throughout the entire season. Rotating Secure Action with Daconil Action or Heritage Action fungicides provides superintendents with a very powerful result in terms of drought mitigation, improved disease control and the ability to recover from abiotic stress for their entire course.”

Posterity will be available Aug. 1, and Syngenta anticipates Secure Action will be available in early September.
