摘要

Action~(R), formerly CGA-248757 (fluthiacet-methyl) is a herbicidal harvest aid for cotton being marketed by Syngenta Crop Protection, Inc. Action~(R) has been tested as a harvest-aid product since 1996 in West Central Texas. The information summarized in this report is from plots established in 1999 and 2000. Action~(R) was applied with a self-propelled ground sprayer to small replicated test plots of furrow irrigated cotton. In these small plots, Action~(R) was equal in its level of leaf defoliation to any currently labeled harvest aid (as of December, 2000). Leaf drop continued slowly even when night temperatures fell in the 50 to 60 deg F range. The defoliation of the cotton plant was slowed when night temperatures dropped below 60 deg F. WhenAction~(R) is used at rates above the 1.25 ounces per acre rate, leaf desiccation is significantly higher for seven to fourteen days, however, the percent of desiccation falls within an acceptable range of less than 20 percent by fourteen days after treatment. When Action~(R) is applied at the 0.60 to 0.63 ounce per acre rate, the level of leaf desiccation was no different by harvest time than harvest aids tested. Action~(R) applied at the 0.60 to 0.63 ounce per acre rate had an equal amount or more regrowth in the terminal and bottom portion of the plant, when compared to the check and all harvest aids tested.
