Five replicated tests were conducted comparing four rates of Pix on 30" cotton in farmers' fields in the San Joaquin Valley. Treatments were: None, 0.5 pts., 0.75 pts. and 1.00 pts. Pix per acre. The plot design was Randomized Complete Block with treatments replicated four times. Acala SJ-2 cotton was planted to all tests and Pix was applied either by air or ground at or shortly after timing specified on the Pix label.

A reduction in plant height was measured at every location with an average of the five tests being about 5 inches. Every comparison of Pix vs. no Pix on cotton grown on 30" rows gave an increase in yield. There was no significant difference at the 5% level, but trends were always the same.
