Proxy/Primo MAXX Tank Mix Registered

A tank mix of Proxy Plant Growth Regulator and Primo MAXX plant growth regulator recently received registration from the EPA, announces Bayer Environmental Science, makers of Proxy.

Registered for many years for use on cool-season golf course turf, Proxy slows turf growth, reducing frequency of mowing and volume of clippings. In addition, Proxy suppresses Poa annua and white clover seedhead development.

Primo MAXX, a plant growth regulator from Syngenta Corp., also slows growth of cool-season golf course turf, such as bentgrass, perennial ryegrass and Kentucky bluegrass. Together, the products improve turf quality.

“The new tank mix registration allows superintendents to control growth, suppress Poa annua seedhead development, and improve turf quality in a single application,” says George Raymond, business manager—herbicides for Bayer Environmental Science.

Raymond adds, “Proxy minimizes turf growth through regulation of cell division, shifting growth toward shorter leaves and more leaves per shoot."

The Proxy/Primo MAXX tank mix should be applied approximately 10 days before the expected Poa seedhead spring flush. Multiple applications may be required.
