Herbicides used for weed control in cotton have not changed appreciably in the last 15 - 20 years. This paper will focus on cotton weed control as an important part of an Integrated Crop Management (ICM) program. Recent studies have shown that cotton is relatively competitive with weeds with the exception of the 4 to 12 week period following emergence of the cotton. To achieve maximum yield, cotton must be kept relatively weed free during this period. When observing cotton growth patterns, this weed free period corresponds with the effective squaring period of cotton. Other issues discussed deal with cultural practices and their effect on weed control.
