Weeds are important pests of California rice systems, and weed management can account for roughly 17 percent of total operating costs, according to a UC cost of production study. Integrated weed management uses cultural and chemical practices and considers the following:
- Prevention (e.g. using certified seed, equipment sanitation, maintaining roads and levees)
- Cultural practices (e.g. land leveling, crop rotation, tillage, winter flooding,...

Bloom is an important time in all crops, and pistachio is no exception. Some of the activities that are often performed around bloom is mowing or tilling row middles, as well as application of burndown herbicides. However, recently released results from a research project led by Lu Zhang (and also included Bob Beede, Gary Banuelos, Christopher Wallis, and Louise Ferguson), formerly a postdoctoral scholar at UC Davis and now a professor at Oklahoma State, may make you want to rethink the timing of those activities. While I'm writing about this, I was not involved in the research.

Winter grains like wheat and triticale are incredibly attractive to nesting ducks. Winter grains are seeded in the fall and grow throughout the winter; by nesting season, a dense stand of winter grains near a planted rice field looks like a great nesting location with brood-rearing habitat just a waddle away. Several studies have found ducks may favor winter planted grains over natural uplands when they're available, and winter grains in rice country can produce far higher mallard nest densities and nest survival than anything in the Prairie Pothole Region.
Unfortunately, some winter grains like wheat have been declining along with its poor market price, and the Sacramento Valley's once robust mallard population is declining...

Crane flies, Tipula oleracea, are once again present on Sonoma and Marin County's range, pasture and cultivated lands this season. Crane flies, sometimes referred to mosquito hawks, lay their eggs in grass; these eggs hatch into small, brown, wormlike larvae that have very tough skin. Larvae feed on the roots and crowns of clover and grass plant during the fall.
Larvae winter in the soil, and when the...
With generous donations from seed companies and support from the California Dry Bean Advisory Board, we're working on two research projects in garbanzo beans this year.
One is focusing on the herbicide Tough 5EC (pyridate) for broadleaf weed control in established garbanzo stands. Currently there are no herbicides registered for use in garbanzos after crop emergence except hooded sprays or directed sprays (not on the crop). Tough by Belchim Crop Protection, is currently being registered for use in garbanzos in other states.
We're conducting two trials with Tough in garbanzos; one at the UC West Side Research and Extension Center and the other at UC Davis. Hopefully this will lead to Tough being registered for use on...
