Last Thursday (July 19th) was the 56th annual UC Weed Day at the Davis campus.
We had a really good turnout again this year with just under 150 participants including weed science researchers, students, farmers, land managers, pest consultants, and government agency people in attendance. Cooperative Extension Specialist Tom Lanini organized the morning field tour and afternoon presentation session and ordered up really great weather for the day.
We started out on campus for registration and signing up for various continuing educaton credits before heading out on two buses and a parade of trucks and vans to the...

Today I thought I'd share a recent research report on the the phenomenon of "enhanced" degradation of the herbicide simazine in citrus orchard soils. Click here for a link to the publication in the open-source journal, Air, Soil, and Water Research (Abit et al. 2012. Air Soil and Water Research 5:69-78). The lead author was a UC Davis post doctoral researcher and her coauthors include UC Davis, USDA-ARS, Fresno State, and UC Cooperative Extension folks.
This work was started several years ago in response to some questions from San Joaquin Valley orchard and vineyardists poor weed control with simazine. They suspected herbicide...

In conjunction with the USDA Range Management group out of Oregon and many Weed Scientists throughout the western US, a two day field school will focus on improving the management and threat of invasive plants, and especially cheatgrass and medusahead. The 2012 EBIPM (Ecologically-Based Invasive Plant Management) Field School and Learning Fair will be held on August 28th and 29th at the Rancho San Rafael Park in Reno, Nevada. The team of instructors will take participants into the field to learn-by-doing with hands-on activities at sites while demonstrating the principles of the EBIPM framework. You’ll gain the knowledge and experience to get out of the never-ending cycle of treating the symptoms...

A quick repost this morning on the upcoming meeting of the Aquatic Plant Management Society. Invasive aquatic weeds are a huge problem in some river, canal, and lake/pond systems in California and around the world. Management of aquatic weeds on a large scale is complicated by: complex ownership and management of water ways, limited mechanical and chemical control options, and aggressive plant biology.
The aquatic plant management society has an annual conference to discuss current research and the state of the art when it comes to manage these challenging plants. Click here for...

I think there's enough blame to go around on this one.

1. Employees should have asked the guy about what he needed to do
2. Employees should have some idea about the herbicides they are selling (or pesticides for that matter)
3. Customer should have read the label before using
4. Ferti-Loam should have put the information in a more visible place on the OUTER label. I'm sure other manufacturers don't do either. However, see #2 and 3 above.
Here are some tips so it doesn't happen to you:
