A study consisting of four replicated, small plot field trials was initiated to examine the effects of foliar applications of ProAct^TM mixed with mepiquat chloride on cotton growth and yield. Tests were established in Arkansas, Louisiana, and Mississippi, and independent agricultural scientists conducted each test. ProAct and mepiquat chloride were applied as needed to the foliage of DP 555 BG/RR cotton. Plant growth and maturity measurements as well as yield were recorded.
