LockUp available to control dollarweed

LockUp specialty herbicide is now available through distributors as a formulated product for superior control of dollarweed in the South. It offers postemergence weed control to lawn care professionals, golf course superintendents, sports turf managers and sod producers.

New granular formulations of LockUp on fertilizer are available from The Andersons, Harrell’s, Howard’s Fertilizer, Howard Johnson’s Enterprises, John Deere Landscapes, Lebanon and Regal Chemical Co. There will be formulations available from other distributors in the future. LockUp provides activity at extremely low use rates (0.02 to 0.06 pounds of active ingredient per acre) when compared tp current products, and shows increased efficacy compared to other herbicide options. Efficacy is increased when applied to wet foliage, and activity can be seen when applied to dry foliage on warm- or cool-season turf.

The active ingredient, penoxsulam, was accepted for review and registration under the Reduced Risk Pesticide Initiative of the U.S. Environmental Protection Agency. It is absorbed via leaves, shoots and roots, and begins to work immediately by translocating throughout the entire plant to achieve control.

LockUp specialty herbicide provides postemergence control for a wide variety of other broadleaf weeds, including white clover, kyllinga, Florida betony, chickweed, lespedeza and dandelion. LOCKUP will be available in combination with 2,4-D and dicamba in the near future for cool-season grasses.
