A study consisting of three replicated, small plot field trials was initiated to examine the effects of three foliar applications of ProAct^TM mixed with glyphosate on cotton growth and yield in a Roundup Ready® Flex variety. Tests were established in Louisiana, Mississippi, and Tennessee, and independent agricultural scientists conducted each test. Treatments were applied three times at 2-4 leaf, 7-8 leaf, and 14-16 leaf stages. Plant growth and maturity measurements as well as yield were recorded.
