Documentation of Weed Infestations in Southwest Oklahoma Cotton

L.D. Smith


Cotton fields were surveyed in eleven counties in southwest Oklahoma in September and October, 1989, prior to cotton harvest. Weed counts began at least 100 feet out into the field and were counted on both sides to the middle of two rows for 50 feet.

Each location represents 10,000 acres or less of irrigated or dryland cotton as indicated, weeds were counted at four different sites in each field. Figures represent the number of times the weed was found and the average number of weeds per 100 feet of row when the weed was found.
