Sequential low-rates of Pix were tested on cotton in 34 trials over a four year period in cotton growing areas of California. Five treatments common to all tests were: 0.13 pints Pix per acre applied at first square, first bloom, and 10 days later; 0.25 pints Pix per acre applied at the same three timings; 0.25 pints and 0.50 pints Pix per acre applied at first square and first bloom, respectively; 0.50 pints Pix per acre applied at first bloom; and an untreated control. A completely randomized block design and four replications were were used in each of the field tests.

There was a slightly larger, yield response when multiple low rates of Pix were applied to cotton grown on 30 inch rows as compared to 38 or 40 inch rows. The label rate of 0.50 pints Pix per acre performed best on 38 or 40 inch rows.
