UC Weed Science (weed control, management, ecology, and minutia)

Dr. Mohsen Mesgaran, who joined the Weed Science Group this year as our weed ecophysiologist, found this plant growing on the research farm at UC Davis. African spiderflower is a summer annual broadleaf plant in the caper family (Cleomaceae), growing up to 3 ft tall and wide.

It may be widely understood that most aquatic and wetland weeds are spread by water currents, but the patchwork of colonizing exotic plants can be puzzling.

Why is weed identification important? Simply stated, because not all management strategies are equally effective against all weed species.

Invasive plants don't get much coverage in the news, especially at the state and national level.

We are doing a trial of eleven aquatic herbicides for their potential to control Brazilian waterweed (Egeria densa).
