In a recent University of Arkansas System Division of Agriculture study, dicamba followed by glufosinate 14 days later was found to be the optimal timing for managing Palmer amaranth.
Research at University of Arkansas System Division of Agriculture explores optimal timing between sequential herbicide applications in XtendFlex technology.
Producers growing XtendFlex cotton have often relied on sequential applications of glufosinate to clean up Palmer amaranth escapes from the initial dicamba application. With the availability of XtendFlex soybeans in 2021, follow-up applications of glufosinate will likely become more common. Now researchers with the University of Arkansas System Division of Agriculture say the timing between sequential applications could help maximize weed control.
