Cultural weed control practices must be included in weed management programs to optimize control and inhibit re-infestation. A healthy, dense turf cover is the best overall defense against weed invasion. Some common cultural weed control practices include planting the most adapted turfgrass species for your environment (i.e. shade, full sun, or hot, dry conditions), maintaining a mowing height of 2.5–3.5 inches, watering deeply but less frequently, and proper soil maintenance including fertilization and core aerification.

Grassy Weeds

Grassy weeds are a problem in all field crops. They must be identified at early stages of growth so they can be controlled before crop yields are seriously threatened. Control measures are not the same for all grassy weeds, so accurate seedling identification is important.

Sorghum Weed Control

Early competition, especially from grass, is critical for successfully controlling weeds in sorghum. There are preemergence as well as postemergence herbicides available for this crop. Early treatment provides the best control of broadleaved weeds with crop stage also being a critical factor for some postemergence treatments.
