With hemp recently legalized for commercial production in the United States, growers are in need of integrated pest management (IPM) guidance. A new profile in the open-access Journal of Integrated Pest Management offers a current synopsis of existing research on insect and arthropod pests of hemp and notes where future research is needed.
Cotton and corn are threatened by growing resistance in the pest Helicoverpa zea (a.k.a. bollworm or corn earworm) to the insecticidal properties of Bt crops. Two researchers identify contributing factors and identify insecticide resistance management practices that could help slow the problem.
A new study of 40 years' worth of data from the mid-Atlantic region of the United States finds that widespread adoption of insect-resistant Bt corn has reduced pest damage and the need for insecticide applications in offsite, non-Bt crops such as pepper, green beans, and sweet corn, as well.
Should growers that use Bt crops plant a separate nearby refuge field of non-insecticidal crops, or use a blended mixture of seeds that produce both in the same field?
