Severe infestations of cabbage aphids can destroy a crop of Brussels sprouts, making them unmarketable. With NIFA funding, scientists from the University of New Hampshire discovered that organic pesticides can be effective in managing the pests.

Researchers compared two different methods of managing cabbage aphids: intercropping with flowers that host aphid predators, and using organic insecticides. They learned that weekly scouting and organic pesticide application were useful in controlling cabbage aphids.
