Palmer Amaranth Weed Killer

Amaranth palmeri Herbicide

Description of Amaranth, Palmer (amaranth palmeri):
Palmer amaranth is a common weed in the desert regions of the southwest United States. However, it was found to be introduced all the way northeast to Indiana. How, you ask? They believe that beef manure from the southwest is to blame.

It's a difficult weed to handle due to the fact that it:
  1. Adapts quickly.
  2. Spreads small seeds.
  3. Produces a lot of seeds (up to 100,000 each plant).
  4. Aggressively competes.
  5. Has a massive herbicide resistance, including resistance to Glyphosate.
Often mistaken for pigweed, it can be easily distinguished by the fact that there is no hair anywhere on Palmer amaranth.
According to the manufacturer approved labels: The following weed killer, applied at the listed application rates, will control Palmer Amaranth.
