Swede midge (Contarinia nasturtii) is a serious invasive pest of Brassica crops, including broccoli, cabbage and kale. It was recently found for the first time in New Hampshire, and we expect that it will continue to move throughout the region. This pest is particularly troublesome for smaller-scale producers, particularly those that lack enough space for crop rotation.

A brand new fact sheet has been published that describes the latest knowledge about organic management of this pest. It’s a collaborative effort by the University of Vermont, Cornell Cooperative Extension, and the University of Guelph. Check it out here!
