Apply post-emergence crabgrass herbicides. These herbicides kill the crabgrass and will completely eradicate any crabgrass populations when used in conjunction with a pre-emergency herbicide. Example herbicides include Fenoxaprop and Dithiopyr, and target crabgrass without harming lawn grass species.tep 3. Use pre-emergence herbicides. These chemicals prevent crabgrass seeds from sprouting, breaking its life cycle. They do not affect already-growing plants, thereby protecting your lawn.
1. Prevent crabgrass from growing in the first place with pre-emergent herbicides. Pre-emergent herbicides act by forming a chemical layer at the surface of the soil. As crabgrass seeds germinate, they take in the herbicide, which prevents them from sprouting and ultimately kills them.Ad.2. Apply pre-emergent herbicides in the late winter/early spring when soil temperatures stabilize at 55Â°F at a depth of 4.s crabgrass seeds germinate, they take in the herbicide, which prevents them from sprouting and ultimately kills them.
