Glyphosate-resistant (GR) goosegrass has shown up in a couple cotton fields in Lake and Dyer counties (picture left).  In these fields, repeated applications of glyphosate failed to control the goosegrass. Unfortunately, by the time the grower realizes that the grass is glyphosate resistant it has 4 or more tillers and is too large for even an application of Select Max or Fusilade to control.  Back in the late 1980s, Select Max or Fusilade did not control large goosegrass.  This appears to not have changed. Part of the issue is that growers are so focused on controlling the GR Palmer that is also present in these fields that they just assume that glyphosate will control the grass.  One can no longer assume that and grassy weeds in fields need to be monitored for control after a glyphosate application.
