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...

Each of us have the entire blueprint for our bodies contained in every cell, and the same is true of plants. This information is stored in the form of an extremely long molecule known as DNA (in human cells its length is ~6 feet). Studying and understanding DNA in plants has led to many advances in weed science including; the development of herbicide- tolerant crop varieties, understanding the causes of herbicide resistance and understanding the origins and spread of weeds in our environment.
Here in California, the weed science group at UC Davis is utilizing this technology to investigate glyphosate resistance that has been detected in California populations of junglerice. Junglerice is a summer grass weed present in many...

We ran the robovator in twin row processing tomato yesterday in the Westside of the San Joaquin Valley (see photo). We conducted intra-row cultivation at up to 5 mph without damage to tomato. With high labor costs and only a trickle of new herbicides we need to take this technology very seriously because it has great potential in California vegetable crops and probably many others like cut flowers.

This is the abstract and a poster from a presentation that I made at the 2016 Weed Science Society of America meeting in San Juan, PR. The results were generated from one run of each of the experiments. At this time, all of the studies have been replicated, the data is being analyzed and the manuscripts are in preparation.
