In the job listing for my position, weed identification and management were never explicitly mentioned. “Natural resource efforts” in the listing only mentioned water, forage, soils and “the wide array of issues” relating to rangeland ecosystem services. Of course, pests are an issue relating to rangeland ecosystem services (healthy water, soil, and air; biodiversity; etc.), but when I first joined UCCE, I did not expect to spend a large amount of time on weeds.
Now I know, a year and a half in, an incoming phone call is more likely to relate to weed management than to any other topic. Ranch visits for any purpose will usually include a discussion of weedy species on the property. While weed management is...
Here is a short summary written by Theresa Becchetti, University of California Cooperative Extension (UCCE) Livestock and Natural Resource Advisor on the Effects of Medusahead on Beef Cattle Gains project.
Livestock and Natural Resource Advisors, Specialists, and faculty have been researching Medusahead (an invasive grass with lower grazing quality) for many years now. We know it reduces carrying capacity on rangelands, creates a thatch that can become a fire hazard, and reduces the diversity of plants on rangelands to the extreme...

Last year about this time, I posted a blog regarding an ongoing trial investigating various herbicides for Pre-emergent Control of Medusahead. I wanted to follow up on that trial which I “deemed” unsuccessful and share some of the data collected in 2017.
The main objective of the study was to test various herbicides for medusahead control. I was interested if some of the work conducted at Colorado State with Esplanade (indaziflam) could be replicated with medusahead. In Colorado field trials, single applications of Esplanade had offered three-year...

As you can tell by going through archived blogs on this site, medusahead (Taeniatherum caput-medusae) is an extremely popular grass. Well, an infamous one, perhaps. I am fairly certain that none of us actually like it. In this blog I will add to the plethora of medusahead posts; but first, a public service announcement.
On May 2, 2017, there will be a Medusahead Management Workshop at Lindcove REC, in Exeter. Online registration is available at ucanr.edu/medusahead. This workshop aims to inform attendees about medusahead biology, its economic impact on cattle operations, and a variety of tools available to...

The weather pattern this year in the Intermountain Region of Northern California has been radically different from what we have seen the previous 4 years. In most years, high pressure usually moves in periodically sending Pacific cold fronts farther north and giving us periods of warm dry weather. However, this winter and so far this spring high pressure has not dominated and we have been continually bombarded by cold fronts.
The frequent rains this winter and spring has resulted in changes in the weed spectrum. One weed we have seen a lot more of in this area is bur buttercup. Bur buttercup (Ranunculus testiculatus) has been widespread this spring and in some cases dense populations have been...
