Cabbage and Turnip Aphids

By Carl Wilson, horticulture agent, Colorado State University Cooperative Extension, Denver

Cabbage and turnip aphids feed on members of the cabbage family, including broccoli and kale. They often spend the winter as eggs on wild or cultivated cabbage and mustard family plants.

Pull and destroy mustard family weeds near your garden this spring. If winged forms do fly in and find your plants, allow natural insect predators and parasites to feed on them. As with any aphid, try to wash them off with a stream of water. Several insecticides available at garden centers also can be useful in combination with these other measures.
