From whiteflies in southern Georgia to bollworms in North Carolina to plant bugs in Virginia, 2016 was a challenging insect year for cotton growers across the Southeast. Dominic Reisig is urging farmers to be prepared for another challenging year.
Reisig, North Carolina State University Extension entomologist, addressed “Emerging Insect Issues in the Southeast” at the annual meeting of the Southern Cotton Growers and Southeastern Cotton Ginners in Charlotte, N.C., Jan. 20, where he provided an insect situation, outlook report and control recommendations.
“Thrips are probably our biggest pest problem in the upper Southeast. When you think about the tough environment you have to plant cotton in early season, the conditions can be brutal,” Reisig said.
With the loss of Temik, North Carolina farmers thought they had a good replacement for thrips control with the use of an infurrow application of Admire Pro along with an insecticidal seed treatment.
Reisig called it a “one-and-done option,” but the challenge now is that resistance has been confirmed in this class of chemistry.
“One of the things we are preaching to our growers is to load up on active ingredients,” Reisig said. “We think seed treatments still have value even though we have this resistance situation. We’re recommending to our growers still use these insecticides but don’t expect them to perform as they have in the past.”
