Last week, Vegetable Crops Advisor Amber Vinchesi and I went out to quantify weed density in our winter cover crop research plots in Meridian, CA. The differences between the plots with a vetch cover crop and the fallow control plots were apparent!
Volunteer wheat is growing throughout the field, which isn't a problem because it is high in biomass, adds organic matter to our soil, and is not going to seed before cover crop termination. In the vetch planted plots we observed a mix of wheat and vetch with very minimal weed pressure. (Also, very little bare soil which reduces our risk of erosion or surface compaction by protecting our soil structure). In the fallow control plots however, winter weeds were more...

Have you listened to a Growing the Valley podcast? Here are a couple you might want to check out.
In this short episode, Phoebe Gordon chats with Dr. Brad Hanson, Weed Specialist with UC Davis. They talk about perennial weed management, as well as two species that have recently become problematic in orchard crops: alkaliweed and threespike goosegrass. We don't know a.../h4>

Arundo donax is devastating to riparian habitat and becoming increasingly widespread in the Sacramento – San Joaquin Delta. To counter this growing problem, the Sacramento-San Joaquin Delta Conservancy (Delta Conservancy) envisions a delta-wide, long-term Arundo Control and Restoration Program to treat Arundo infestations and restore native vegetation to improve habitat along Delta waterways.
Since 2014, the Delta Conservancy has led a pilot project controlling Arundo and restoring riparian forest habitat in the Cache Slough Complex, funded by the California Department of Water Resources (DWR), and partnered with the Solano Resource Conservation District (SRCD) and Sonoma Ecology Center (SEC). As part of the Delta...

Hands-on approach to Weed Science School 2019
Most of us learn best by doing, which is why Weed Science School 2019 promises to be better than ever this year.
The course offers more hands-on training and will include four rotations where participants can be involved in weed identification, spray nozzle demonstration, an adjuvant demonstration, and an herbicide symptomology lab. In addition, we provide several lectures on weed biology, ecology, organic weed management techniques, herbicides action and resistant management and prevention discussions, as well as various aspects on environmental fate of herbicides.

Sharing a plug for a weed science short course at Colorado State University for a colleague.
"A Short Course on Herbicide Mode of Action and Herbicide Resistance". This course has been traditionally held at the University of Tennessee Knoxville but will be moved to Fort Collins, Colorado for the 2019 version. See the attached flyer for more info and contact information.
Stay tuned also for the official announcement, agenda, and registration information for UC Weed Science School (Aug 20-22, 2019).
