New Crop Rotation Recommendations for Swede Midge
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program
New Cornell research has demonstrated that brassica crop rotations of 500 ft (down from 3000 ft) and 3 months (down from 3 years) could effectively "crash" a swede midge population when fields are secluded from each other, making crop rotation a much more feasible strategy for small farms. A new fact sheet details the new crop rotation recommendations and provides information on the pest's life cycle, biology, and crop preferences in addition to real-world examples of crop rotation. The crop rotation strategies were developed to serve the needs of small organic farmers, but have utility for conventional farmers as well.

IPM Field Day for Urban Growers
September 10, 2026
Buffalo, NY
Join us for a hands-on field day exploring integrated pest management and season extension tools for urban growing spaces and the opportunity to build community with local growers!
This event will focus on best practices for using row covers and rat mitigation. Check out our CCE demonstration trial using insect exclusion netting to manage swede midge, an invasive fly that causes damage to brassica crops. Explore how to identify rat activity, reduce attractants, and strengthen site management. Hear from local growers on how they manage pests with a focus on organic management and how they extend the season on their farms and gardens.
