Selective Weed Killer For the selective control of Crab Grass, Paspalum, Mullumbimby Couch, Nutgrass, Clover and other weeds in domestic lawns.
 
Crabgrass is a summer annual that begins to germinate in early spring, and germination continues through summer. Because of this long germination period, obtaining full-season control can be difficult. 
 
DSMA controls emerged crabgrass in established turfgrass. Generally, multiple applications are required, especially for well-tillered crabgrass. The tratment can cause yellowing or burning of turf, such as in tall fescue. This injury is temporary and turfgrass will outgrow the damage in a week or two. 
MCPA controls broadleaf weeds, including thistle and dock, in cereal crops and pasture. It is selective for plants with broad leaves
 
DSMA does not provide residual crabgrass control, so you must either repeat applications for later-germinating plants or apply a pre-emergence herbicide. Follow label directions in regard to the addition of a nonionic surfactant.
