Large crabgrass resembles smooth crabgrass but has hairs on its leaves and sheaths. Use pre- and postemergent herbicides with dithiopyr to control and kill this invasive lawn pest.

Smooth crabgrass is similar to large crabgrass but lacks hairs on the leaves and sheaths. Herbicides containing dithiopyr are exceptional at killing, preventing and controlling this weed species.

Southern crabgrass is a warm-season annual and grows laterally along the ground. It prefers open, sunny areas and can be eliminated with herbicides containing dithiopyr for pre- and postemergent control.

Crowfootgrass has seed heads that look like crow's feet. It produces 60,000 seeds during its lifetime. A pre-emergent herbicide labeled for this weed is an effective way to prevent an infestation.

Curly dock thrives in moist areas and has wavy leaves. It produces greenish flowers in clusters that turn reddish-brown as they mature. Two-, three- and four-way postemergents are best for weed control.
