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...

Elise Gornish, Josh Davy, Travis Bean, and I are testing the use of sheep for management of late-season invasive annual grasses. This trial is taking place at five sites at the Hopland Research and Extension Center – two with barb goatgrass, two with medusahead, and one mixed.
Treatments include grazing at boot stage (32 sheep-days on 324 m2), revegetation with native spp vs forage spp, and treatment with low or high rates of glyphosate at tillering, boot stage, and heading. The main plots are 18 m x 36 m including an 18 x 18 grazing enclosure and are replicated three times at each site. All treatments are crossed, for a total of 48 subplots in each main plot.
Grazing was conducted from mid-April to...
