LOCKUP specialty herbicide from Dow AgroSciences is a formulated product to control dollarweed in the South. It offers postemergence weed control, and new granular formulations provide activity at low use rates (0.02 to 0.06 pound of active ingredient per acre). Efficacy is increased when applied to wet foliage, and activity can be seen when applied to dry foliage on warm or cool-season turf.
Penoxsulam, the active ingredient, was accepted for review and registration under the Reduced Risk Pesticide Initiative of the U.S. EPA. It is absorbed via leaves, shoots and roots, and begins to work immediately by translocating throughout the entire plant to achieve control.
LOCKUP controls a wide variety of other broadleaf weeds, including white clover, kyllinga, Florida betony, chickweed, lespedeza and dandelion.
