The continued use of the cotton growth regulator, Pix, is key to continued high cotton production in California. A new dry, flowable (DF) formulation was tested to see if it was as effective as the original Pix liquid (4.2% ai) formulation. The new DF formulation will reduce transportation, storage, and container disposal costs. In four replicated experiments, the yields for the liquid and DF formulations were 1346 and 1348, respectively.
