Available from the NPM Program! A new visual guide for identifying two of the pigweed species of special concern in Wisconsin: Waterhemp (Amaranthus tuberculatus) and Palmer Amaranth (Amaranthus palmeri). Waterhemp is common in Wisconsin and has documented resistance to some herbicides. Palmer is not common in Wisconsin but with increasing populations in neighboring states, it is of concern since there has been documented resistance to many herbicides.
This informative card has background information about these two species, as well as a visual guide for identifying what type of pigweed you might have. The printed publication is a folded card that is 4 inches wide by 7 inches tall.
