Designed for turfgrass applications, Avenue® South Broadleaf Herbicide for Turf contains 4 active ingredients: 1. Penoxsulam, is in the sulfonamide family and the acetolactate synthase (ALS) enzyme is inhibited in the weed causing the weed to slowly starve affected plants of these amino acids. Penoxsulam is absorbed via leaves, shoots and roots and begins to work immediately by translocating throughout the entire plant to achieve control. 2.Sulfentrazone is in the aryl triazolinone family and inhibits protoporphyrinogen oxidase (Protox), a pivotal enzyme in chlorophyll production. Without this key enzyme, a build-up of peroxide-like compounds occur, thus causing the plant cell membranes of weeds to rupture. 3. 2,4-D is an auxin-type herbicide. It is absorbed through the leaves and is translocated to the growing points of the plant, causing weed stems curling and twisting, leaf cupping and withering, and eventual plant death. ￼4. Dicamba is absorbed through the leaves and roots and has multiple modes of actions for hard- to-kill broadleaf weeds. These combined herbicides provide limited residual activity. Weeds are controlled by affecting multiple sites within the broadleaf weeds. The symptoms of susceptible broadleaf weeds include leaf and stem curl or twisting and weed yellowing. Avenue South offers these advantages: • Excellent postemergent activity with proven performance for broadleaf weed control in turfgrass. • High selectivity (turfgrass safety) in established warm-season turfgrass and cool-season turfgrass. • The combination of these 4 active ingredients provides effective weed control for common and troublesome weed species in turfgrass, such as dollarweed (pennywort). • Generally, the weed injury symptoms can be noticed within a few days of the application and weed death can occur within 14 to 28 days.
