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

The Madsen lab is working on South American spongeplant (Limnobium laevigatum), a relatively new invader in the Sacramento-San Joaquin Delta (Photo 1).

Weeds are one of the biggest challenges to organic vegetable production and can be expensive to manage since herbicides are not an option.

Summer is here, and we're halfway through 2019 already! Why not get jump on finishing up your continuing education units by taking online courses from the UC Statewide IPM Program (UC IPM).

During summer 2019 the Madsen lab is sampling curlyleaf pondweed (Potamogeton crispus) at multiple locations to determine the effects of water temperature, air temperature, and water turbidity on plant growth and reproduction.

The Delta Region Areawide Aquatic Weed Program has been focusing science and the application of science onto the management of invasive aquatic weeds such as water hyacinth, Brazilian egeria, and water primrose in the Delta.
