The battle against herbicide-resistant Palmer amaranth continues unabated in North Carolina, writes John Hart at Southeast FarmPress. Charlie Cahoon, North Carolina State University Extension weed specialist for cotton and corn, says growers must integrate a broader system to better control troublesome weeds.
“Folks it’s time to circle the wagons. Herbicide resistance issues are not going away. We have to start thinking about resistance from a complete weed management standpoint. There has been a big push for integrated weed management in response to herbicide-resistant weeds and it’s high time we got on board,” said Cahoon.
Speaking at the Cotton Field Day at the Upper Coastal Plain Research Station in Rocky Mount in September, Cahoon emphasized cover crops as an important tool for North Carolina cotton farmers to battle Palmer amaranth, horseweed, and other herbicide-resistant weeds. He stressed that cover crops won’t replace herbicides for controlling problem weeds, but they will work in tandem with and take a lot of pressure off herbicides.
