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). If you are a license or certificate holder from the California Department of Pesticide Regulation (DPR), and your last name begins with the letters M through Z, you should be receiving your renewal packet in August.
We're excited to announce some changes.
- In January, we switched all of our online courses to a new learning system located at https://campus.extension.org/. This new system...

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. We collect plants each month and obtain the biomass for each part of the plant: shoots, roots, inflorescenses, and turions (asexual reproduction structures). Three locations are in Lake Berryessa, three in Putah Creek between Winters and Monticello Dam, and three in the Sacramento-San Joaquin Delta. At each location we take plant & sediment samples using a weighted dredge (Berryessa, Delta) or handheld dredge (Putah Creek, pictured below).
On one recent trip the rope broke on...

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. As part of the conclusion of the DRAAWP, a special session has been organized for the 2019 Joint Annual Meetings of the Aquatic Plant Management Society and the Western Aquatic Plant Management Society (http://www.apms.org/annual-meeting/2019-annual-meeting/). Six oral and nine poster presentations have been accepted for this upcoming event, to be held July 14-17, 2019 in San Diego, California. The DRAAWP executive committee have also planned on a...

Onions is a challenging crop in which to achieve good weed control. They are planted in high density configurations that preclude the effective use of cultivation. Cultural practices such as locating plantings in fields have low weed populations, as well as preirrigating up a flush of weeds followed by killing them with shallow cultivation can be effective in minimizing the population of weeds that emerge during the crop cycle. In general, excellent weed control for many of the common cool and warm season vegetables can be accomplished by a combination of the registered pre and post emergence herbicides. The weed control challenges in onions occurs with weeds that are not well controlled by currently registered herbicides. It is...
