The super weed Palmer amaranth has been found in a seventh North Dakota county in a year's span and in south central North Dakota for a second time this summer....

Palmer amaranth can grow 2 to 3 inches a day, typically reaching 6 to 8 feet or more in height. Left uncontrolled, a single female Palmer amaranth plant typically produces 100,000 to 500,000 seeds. It is resistant to multiple herbicides, can cause substantial yield losses and greatly increase weed management costs in soybeans and corn.
