Sorghum is, and will remain, an important crop in the USA, especially in marginal environments due to its low input requirements and high resilience. Weed management is a key production challenge for sorghum, and the herbicide tools available are very limited, particularly for post-emergence (POST) control of grass weeds. The weedy relatives such as shattercane and johnsongrass present challenges for selective control in sorghum due to genetic similarities. This chapter presents a number of weed management options and considerations for sorghum, and discusses the critical period for weed control, placing an emphasis on pre-emergence (PRE) control of grasses and other tough-to-control annual weeds. It is concluded that an integrated weed management approach, encompassing a strategic application of PRE and POST herbicides used in combination with non-chemical tactics, will be critical to achieving sustainable weed management in sorghum.
