weed feed seed for southern lawns

In fescue lawns, grassy weeds such as crabgrass, goosegrass, and dallisgrass can also be controlled with postemergence herbicides. Products containing fenoxaprop and quinclorac are recommended.

Preemergence herbicides are generally effective for six to 12 weeks, depending on the product. For season long control, make a second application nine weeks after the first. Before using, read the entire label and follow it precisely. See Table 1 for examples of herbicides and products.

Guidelines for Using Postemergence Herbicides

Most granular preemergence herbicides should be watered in with about ½ inch of irrigation water immediately following application. This activates the herbicide, which is absorbed by the young roots of weeds as they begin to grow.

Preemergence Herbicides: Preemergence herbicides are applied to the soil prior to weed seed germination. They provide good control for many annual grassy weeds and are the best weapon against crabgrass. They also control some broadleaf weeds. Most are in a granular formulation, but some are applied as a liquid spray.
