The objective of this study was to evaluate the carryover effect of Cadre application on cotton growth and yields. Cadre was broadcast applied pre-emergence at rates ranging from 0.001 to 0.063 lb ai/A. Generally, cotton plant height decreased with increasing Cadre applications. The shortest plants were noticed with the highest application of Cadre in cotton (0.063 lb ai/A). The average boll and node numbers per cotton plant were generally high, except for the treatment with the Cadre DG application at 0.063 lb ai/A. The highest lint uniformity was obtained with applications of Cadre DG at 0.016, 0.063, 0.004, and 0.002 lb ai/A, and also from untreated control. Cadre application did not influence the plant index, leaf area index (LAI), percent lint, lint yield, and lint micronaire, length, staple, and strength.
