PBI-Gordon Corporation announces that the U.S. Environmental Protection Agency (EPA) recently approved Federal registration for Vexis® Herbicide Granular.

Based on a new proprietary active ingredient, Pyrimisulfan, Vexis is the result of an exclusive partnership between PBI-Gordon Corporation, Kumiai Chemical Industry Co., Ltd. and their US subsidiary K-I Chemical U.S.A Inc.

Vexis is formulated for use on residential and commercial sites, sports facilities, and golf course tees, fairways, and roughs. Primary features include:

  • Excellent post-emergent control of sedge and kyllinga species, including purple and yellow nutsedge, cockscomb, green kyllinga and false green kyllinga.
  • A low-rate, non-phenoxy product, Vexis has exhibited activity against weeds that have developed resistance to ALS-inhibiting herbicides.
  • The application rate is 4 lb. per 1,000 sq. ft. (174 lb. per acre). The maximum annual use rate is 8.26 lb. per 1,000 sq. ft. (360 lb. per acre). Retreatment after 30 days is allowed.
  • Vexis can be used on a wide variety of cool- and warm-season turfgrasses: Kentucky bluegrass, fine and tall fescues, perennial ryegrass, bentgrass, Bermudagrass, bahiagrass, buffalograss, kikuyugrass, seashore paspalum, St. Augustinegrass (including improved varieties, such as bitterblue and floratam), and zoysiagrass.
