Veri-Green Southern Weed & Feed 5m Kills over 40 listed broadleaf weeds, as well as nutsedge and kyllinga. Contains Penoxsulam, not atrazine, for superior control of broadleaf weeds in St. Augustinegrass, Zoysiagrass, Bermudagrass, and Centipedegrass. Root absorption means that the particle doesn't have to stick to the leaves. Will not harm bentgrass, Kentucky bluegrass, perennial ryegrass or tall fescue lawns. Feeds lawns for up to three months. Not for use on bahiagrass, dichondra, or carpetgrass lawns.
