North Carolina State University Extension Weed Specialist Wes Everman continues to urge North Carolina farmers to be on the lookout for resistant waterhemp, redroot pigweed and Palmer amaranth across the state. Speaking at the Blacklands Farm Managers Tour Aug. 4 at Turnpike Farms in Pantego, N.C., Everman said Palmer amaranth is now showing resistance in spots across North Carolina to glyphosate, ALS, HPPD and PPO technologies. He noted that testing is also underway to see if Palmer amarnath is resistant to atrazine. He also said resistant redroot pigweed is popping up in spots across the state.
