Union Fungicide SC

Union Fungicide SC is a professional broad-spectrum turf fungicide combining 5.84% cyazofamid and 3.25% azoxystrobin for control of major diseases in cool- and warm-season turfgrass. Featuring FRAC Groups 21 and 11, Union provides two complementary fungicide modes of action for Pythium diseases, brown patch, anthracnose, fairy ring, gray leaf spot, summer patch, take-all patch, and numerous other difficult turf diseases.

Union combines QiI and QoI fungicide chemistry in a flowable suspension concentrate designed for preventive disease-management programs and selected early-curative applications. Its broad turfgrass tolerance, flexible 14- to 28-day application intervals, and strong activity against both foliar and root-infecting diseases make Union a valuable option for golf courses, sports turf, sod farms, residential and commercial lawns, parks, and institutional turf.

Application Notes

Apply Union Fungicide SC at 2.9 to 5.75 fl oz per 1,000 sq ft depending on the target disease and disease pressure. Most foliar diseases are treated on 14- to 28-day intervals, while Pythium root rot is generally treated on a 14- to 21-day interval and Pythium root dysfunction on a 21- to 28-day interval. Use the higher labeled rate and shorter interval where disease pressure is severe or prolonged.

Apply in 2 to 4 gal of water per 1,000 sq ft for most broadcast applications. For fairy ring, use 4 gal of water per 1,000 sq ft and irrigate immediately after application with 1/8 to 1/4 inch of water; adding a wetting agent to the final spray solution is also directed. Root-infecting diseases such as Pythium root rot, Pythium root dysfunction, necrotic ring spot, summer patch, and take-all patch require irrigation after application as specified on the label.

Do not exceed 5.75 fl oz per 1,000 sq ft per application or 17.3 fl oz per 1,000 sq ft per year. Do not make more than two consecutive Union applications before rotating to a fungicide with a different mode of action. Always read and follow the complete product label.
