Cotton fields in six south Georgia counties were surveyed in late season prior to or after harvest. A total of 15 fields was sampled. The survey technique consisted of counting mature weeds from an area two rows (36-38 inch row spacing) wide by 50 feet long at four locations in each field.

The most common weed was Cyperus spp. including yellow nutsedge and annual sedges. The most prevalent broadleaf weeds were cocklebur (Xanthium strumarium); Cassia spp., coffee senna, and sicklepod; and the most common grass was Texas panicum (Panicum texanum). With only two exceptions, the 18 genera counted occur in all counties of the southern cotton producing region of Georgia. Redweed (Melochia corcborifolia) appears to be limited to counties in southwest Georgia which are 60 miles or less from the Florida border, while cowpea (Vigna spp.) is more common in areas further north.
