Abstract
Near isogenic strains of okra, super okra and normal leaf cotton ( Gossypium hirsutum L.) were grown in rows spaced 25, 50, and 100 cm apart and were sprayed with various combinations of trifluralin (α,α,α,trifluoro-2,6-dinitro- N,N -dipropyl- p -toluidine) and fluometuron [1,1-dimethyl-3-(α,α,α,-trifluoro- m -tolyl)urea]. Neither row spacing nor leaf type had any effect on early season weed control. Late season control was better with normal and okra leaf types than with the super okra leaf type. Weed control was significantly better with additional postemergence application of herbicides than with only preplant and preemergence applications. Although the cotton varied in opening date with herbicide programs there was no difference in total yield.
