Results for the cotton defoliation study that was sprayed on July 28, 2017 in Wharton, Texas are listed below. A rating of the July 28th application (Application Timing A) of 13 different defoliation treatments was taken on August 2, 2017. The percentages given for % Defoliation, % Desiccation, % Green Leaf, and % Open Boll for the attached report is a measure of only Application A at 5 days after spraying. The attached report does not reflect the second application of defoliant (Application Timing B), as the treatments that called for a second spraying were not sprayed until August 4th. Approximate cost estimates reflect total cost of the treatment (e.g. Total cost of Treatment A and Treatment B). I will follow up later this week with the results of the defoliation study taken at 12 days after the initial defoliation. The second report will also reflect % regrowth for the 13 treatments.
