Effects of PIX and PREP on Long and Short Staple Cotton, Safford Agricultural Center

Abstract

Effects of 5 rates of PREP and 2 application dates of PIX were evaluated on long staple (S-6) and short staple (DP 90) cotton. Generally, crop maturity increased linearly with increasing rates of PREP. Some yield trends were seen with PREP applications. Timing of PIX application is important. Too early applications shorten plants but may slightly decrease yields; too late applications have very little effect.
