In the coffee shop, it is known as palmer pigweed. In university circles, it is referred to as Palmer amaranth. Whatever you want to call it, this weed is the No. 1 weed to watch.
It is important to know How to identify it and more importantly, how to manage it. Palmer amaranth is native to the Southwest U.S. but has been expanding into other regions for the past 50 years.
If ignored or otherwise not effectively managed, Palmer amaranth can reduce corn and soybean yields to nearly zero.
Palmer germinates from early spring until late in the growing season, growing up to 2.5 inches a day. The days of "one spray one day and done" are long gone.
Take control of the obnoxious weed before it takes control of your bottom line.

If pre-plant scouting reveals Palmer amaranth plants taller than 4 inches, consider using tillage instead of herbicides to control the plants.
