PBI-Gordon Corporation announced that the US EPA recently approved Federal registration for Vexis herbicide granular. It will be available for sale in mid-2019.
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 commercial sites and sports facilities. Primary features include:
- Excellent post-emergent control of sedges and kyllinga species, including purple and yellow nutsedge, cockscomb, and false green kyllinga.
- A low-rate, non-phenoxy product, Vexis has exhibited activity against weeds that have developed resistance to ALS-inhibiting herbicides. Application rate is .03 to .06 lbs. AI/Acre. Maximum annual use rate is .09 lbs. AI/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), and zoysiagrass.
The first registered products containing Vexis will be in a granular formulation, which will help reduce off-target drift and volatility compared to products currently available. It will be sold in a 2-lb. “shaker” can and in a 35-lb. bag. It will be available alone or in combination with other active ingredients.
