Much of the Palmer amaranth that is now 3 to 5” tall is flowering. Quite a few folks have asked what the reason is for this early flower. The Palmer amaranth has been triggered to flower by the short day length of March and now early April. Quite literally the Palmer amaranth that has emerged thinks it is late August or September.

There have been numerous reports of poor control of cover crop or volunteer wheat with glyphosate + dicamba or glyphosate + dicamba + Leadoff over the last ten days.
