The EPA recently approved PBI-Gordon's Union Fungicide SC. It will be available for sale in early 2020.

Testing has showed that Union is highly effective in the preventative and curative treatment of Pythium diseases — including blight, damping-off, root dysfunction and root rot — brown patch, anthracnose, cool-weather brown patch, yellow patch, fairy ring, gray leaf spot, red thread, summer patch and Rhizoctonia. It is approved for use on golf courses, residential and commercial properties, sod farms and sports fields.

A flowable liquid, Union is a formulation of the active ingredients azoxystrobin and cyazofamid. It includes dual modes of action and a proprietary combination of chemistry found in FRAC Groups 11 and 21.

Union is labeled for use on all cool-season and warm-season turfgrasses, including Kentucky bluegrass, fine fescues, tall fescue, perennial ryegrass, bentgrass, common or hybrid Bermudagrass, bahiagrass, buffalograss, centipedegrass, kikuyugrass, seashore paspalum, St. Augustinegrass and zoysiagrass. The labeled application rate range is 2.9 to 5.75 fluid ounces per 1,000 square feet and includes no temperature restrictions.
