Palmer amaranth

Overview

Palmer amaranth (Amaranthus palmeri) is an aggressive weed that can devastate a field of crops. A single plant can grow several inches in the course of a day and disperse up to one million seeds in its lifetime. Palmer has already developed resistance to popular herbicides, making it one of the most challenging noxious weeds in agriculture today.

Research Connection

MITPPC is funding studies to forecast the expansion of Palmer amaranth in changing environmental conditions so state agencies and land managers can stay ahead of the threat. MITPPC is also exploring new ways to keep Palmer amaranth seeds out of native seed mixtures for conservation plantings.
