Waterhemp and Palmer amaranth are two of the most loathed weeds locally.
Both are members of the pigweed (amaranth) family. Both can produce half a million seeds or more on a single female plant. Both species are able to quickly adapt when farmers use the same herbicides over and over again to combat them. Both weeds germinate over a long period of time and can be seen popping up through the canopy late in the season.
