From the UC Cooperative Extension Monterey County Crop Notes newsletter (March/April 2014)
Excellent weed control is essential for economically producing cilantro and parsley. Both crops have had various weed control challenges over the last few years. Cilantro and parsley are in the celery family and both are small acreage crops (cilantro 980 acres and parsley 533 acres in Monterey County in 2012) that are important to the local economy. In our modern production systems, both crops are planted in dense plantings (24-33 seedlines) on 80-inch wide beds. Parsley has been mechanically harvested for...

Today, May 8th, marks the 100th anniversary of the signing of the Smith-Lever Act that resulted in the creation of Cooperative Extension. The UC Division of Agriculture and Natural Resources (ANR) and the three land-grant campuses in the UC system (Davis, Berkeley, and Riverside) as well as most of the county-based UCCE offices are celebrating this milestone in various ways under the banner “A Celebration of Science and Service”.
I have been involved in applied research and extension for almost 20 years during career stops at Iowa State University, University of Idaho, Oregon State University, Colorado State University, USDA-ARS, and for the past five years on campus at UC Davis. I'm very proud...

From the Invasive Plants in Southern California blog ¦¦ May 3, 2014
The Apiaceae family is a large (300+ genera worldwide) and interesting group of native plants (water hemlock, wild carrot, sanicle), weeds (fennel, poison hemlock, queen ann's lace) and important crops (carrot, celery, dill, fennel and parsley). The family is often referred to as the umbel or the Umbelliferae, the old family name. Some genera are represented in California as native plants (Daucus pusillus, wild carrot), crops (D. carota, carrot) and weeds (D. carota, Queen Ann's lace, yes, the weed and the crop are the same...

A recent blog post titled–Plant growth and development and herbicide efficacy discussed herbicides like glyphosate and imazapyr that move through plants in the sugar conducting tissues (aka phloem or symplastic system).
There are some herbicides that move in the water conducting tissue (aka the xylem or apoplastic system). These herbicides, mostly in older classes of chemicals, enter plants through the roots and travel upward to the leaves where you see their effect. Many of these herbicides are only used in crops, so it is unusual that anyone working in a natural area will ever encounter them.
Others, such as diuron or bromacil are used to some in roadsides, under pavement, industrial areas, railroad beds, and...

Weed management research will take center stage at UC Davis on July 10th, when scientists, students, regulators and weed managers gather for the 58th annual Weed Day.
“Weed problems can vary from simply being a headache and annual management concern to being ecosystem-shifting challenges in crop and non-crop areas in California” said Cooperative Extension Specialist Brad Hanson, who is chairing this year's popular event. “Weed Day is an opportunity to see ongoing weed management research on the UC Davis campus and to discuss some of the weed research projects being done in other parts of the state.”
The morning field tour will include herbicide research in annual fruit and vegetable...
