The onset of colder than normal weather always brings up the question of how the cold will affect insect populations in the upcoming growing season. Though the answer to this question seems simple it is actually very complex.

A small weevil that lives inside corn kernels is costing Georgia growers millions of dollars each year. A University of Georgia scientist has teamed up with farmers and county Extension agents to put a stop to the maize weevil, the No. 1 insect pest of stored corn.
Capture 3RIVE 3D in-furrow corn insecticide from FMC has received EPA registration for use with the new 3RIVE 3D ultra-low volume, in-furrow delivery system. The 3RIVE 3D system allows growers to treat up to 500 acres in one fill, using less than one-tenth the liquid carrier volume typically required to treat the same acreage.
To help U.S. corn growers and consultants tackle growing insect resistance to Bt corn, university researchers have developed an online seminar series titled "Corn Rootworm Management in the Transgenic Era."
Since its commercialization in 2003, Bt corn has-and still is-proving to be an important technology for the control of insect pests, higher yield production, and higher quality grain. In recent years, however, the western corn rootworm's increasing resistance to Bt corn has caused some alarm.
To date, fall armyworms have not been a major crop pest in North Carolina, since they can’t survive a winter freeze. Studies have shown that these insects often migrate north from Florida, and this year they were found in North Carolina corn fields as early as May. The real fear is that these Bt-resistant armyworms will move from corn to cotton.
Over the past several years, farmers, academics, seed companies, and retailers have worked together to identify Best Management Practices (BMPs) to help manage corn rootworm, one of the most devastating pests for corn.
