Four field experiments were conducted in 1992 in Arizona to evaluate cotton crop response to several treatment regimes of multiple applications of PIXTM (an anti - gibberellicacid plant growth regulator). Treatment regimes used in 1992 employed higher rates of PIX/acre /application and extended times of applications later into the fruiting cycle than earlier experiments in 1988 through 1991. Some treatments used exceeded currently labeled maximum use rates in an attempt to evaluate the possible need of increasing maximum rates. Similar to earlier experiments, results in 1992 demonstrated the ability of some PIX treatments to significantly reduce plant height, relative to the untreated check treatments. Excellent fruit retention levels were experienced in each experimental site in 1992, irrespective of PIX treatments. Lint yield results revealed significant differences (P ≤ 0.05) between several selected treatments at two of the locations in 1992.
