摘要

Achange in weed thinking is keeping David Nichols'farm profitable. "We've learned the hard way," says the Tennessee farmer, as he talks about weed management on his 3,500-acre family farm, which includes corn, wheat and soybeans.Nichols has faced glyphosate resistance in his fields over the past seven years. First he noticed mares-tail. Then came Palmer amaranth and waterhemp. He discovered these resistant weeds by taking notice of every field and the areas that had been sprayed. When weeds reappeared, he knew they were resistant.
