Sicklepod, cocklebur, annual morningglory, yellow nutsedge and southern crabgrass were found in at least 33% of the cotton fields surveyed in northwest Florida during the fall of 1990. The average density observed in the fields infested with these species ranged from 74/100 row ft for yellow nutsedge to 5/100 row ft for cocklebur. Of the five species found most often in Florida cotton fields, the broadleaf species sicklepod, cocklebur and morningglory, along with wild poinsettia, would be considered the most difficult to control. The results of this survey demonstrated the need for an effective postemergence over-the-top herbicide for broadleaf weed control in cotton.
