Although I am retired, I still am passionate about weeds and decided to continue my Labor Day Tour of the first known infestations of Palmer amaranth in Iowa. I started this ‘survey’ in 2014, links to earlier reports are found at the end of this article. My efforts do not involve a systematic sampling of Palmer amaranth infestations at these sites, but rather casual ‘hit and run’ observations. All but one of the sites involve less than 2 acres, so it is relatively easy to subjectively evaluate the prevalence of Palmer and observe changes in numbers from year to year.
