It’s been less than two years since University of Idaho Extension weed scientist Albert Adjesiwor’s fears were realized and a pair of problematic pigweeds — Palmer amaranth and waterhemp — were first found in Idaho. Yet it’s already clear to Adjesiwor that the weeds have established a firm foothold throughout the Magic and Treasure valleys. He acknowledges the window to eradicate the two invaders has closed, and his focus must shift toward educating farmers about how to manage them. And managing Palmer amaranth and waterhemp is no easy task.
