SAVE THE DATE! – November 5, 2015

For the inaugural Do No Harm workshop: Considerations of pathogens, pests, and plant disease in restoration activities at the UC Palm Desert Campus.

Check out: http://donoharm.ucdavis.edu/ - registration is open! Discounted student registration is available.

We invite restoration practitioners, native plant nurseries, researchers and agencies to learn how to identify and address issues of unintentional pests, pathogens and disease spread through ecological restoration activities.

In addition to presentations and networking opportunities, this one-day workshop will host a poster session. We invite poster submissions focus on a restoration and pathogen/pest theme.

Sponsorship opportunities are available – for more information, check out the website or contact egornish@ucdavis.edu.

We look forward to seeing you in Palm Desert in November!

59th annual UC Davis Weed Day - July 16, 2015

The 59th annual Weed Day at UC Davis will be held next week on Thursday July 16th.   It's not too late to register but there are only a few spots left before we reach capacity.

CE Specialist Joe DiTomaso is the Weed Day chair this year and he has organized a great morning field tour where we'll look at on-going herbicide trials in tomato, melon, safflower, and nut orchards.  We'll also have a demonstration of a machine vision robotic cultivator in transplanted vegetables, a herbicide symptomology demonstration, and a visit to the USDA-ARS aquatic weed research facility.  Following tradition, we'll also have a weed ID quiz (with fabulous prizes) and then have a catered lunch on campus.  

After lunch, we'll be inside (ie. in air conditioning), for  a series of presentations on off campus weed research ranging from organic lettuce, to invasive trees, to herbicide resistance in rice and orchards, to invasive grasses and biocontrol programs.  Lots of good information from a wide range of weed researchers.

For more information on registration for Weed Day and to see the detailed agenda, go to the Weed Research and Information Center (WRIC) Weed Day 2015 Webpage


Other upcoming weed science programs on my radar include:

UC Davis Weed Science School - August 18-20th, 2015 in Davis.

California Weed Science Society annual meeting - January 13-15, 2016 in Sacramento.

Western Society of Weed Science annual meeting - March 7-10, 2016 in Albuquerque, NM

Hope to see you at Weed Day!

UC-IPM Avocado Pest Management Guide updated and republished

A quick post today to share a link to the recently revised "UC IPM Pest Management Guidelines for Avocado" (UC ANR Publication #3436).  You can download the whole document as a pdf here, or use it online at the above link

Although there are also well-written sections on general avocado pest management, as well as specific information on insects, mites, and diseases of avocado, since this is the Weed Science blog, I'd better post a link directly to the Integrated Weed Management section authored by:

  • B. A. Faber, UC Cooperative Extension, Santa Barbara and Ventura counties
  • C. A. Wilen, UC Statewide IPM Program, San Diego County 
  • B. D. Hanson, Plant Sciences, UC DavisR. Elkins, UC Cooperative Extension, Lake County
  • with contributions from W.T. Lanini, A. Shrestha, and P.A. Phillips

I think these PMGs are among the most useful sources of pest management information published by the UC Statewide Integrated Pest Management Program. These agricultural and home garden pest management guides are updated every year or so with extensive revisions every few years. The authors usually include University of California faculty, specialists, and farm advisors and the guides are produced and edited by UC Statewide IPM Program, University of California, Davis. 

Visit the UC IPM homepage for more pest management information.

Take care,

Life after weed science

From the Davis Enterprise | June 26, 2015


Clyde Elmore's nature photos to show at Buehler Alumni Center

Photojournalist Clyde Elmore will host a photographic exhibit from Monday, July 6, through Aug. 28 at the Buehler Alumni Center, off Mrak Hall Drive on the UC Davis campus. This will be the seventh annual exhibit of wildlife and landscape images. He will show animals and landscapes from Botswana, Kenya and Tanzania, as well as North America, including Alaska.

The theme of the exhibit is “In the Wild,” although five of the 24 images are of managed animals such as the critically endangered Amur Leopard from northeastern China and southeastern Siberia (only 300 remaining) and gray wolfs.

A reception will be from 4 to 7 p.m.  Friday, July 10, in the center's library.
As a young boy growing up on a farm outside Alva, Okla., Elmore spent a lot of time working with cattle, sheep and pigs, never thinking about art and photography. After completing bachelor's and master's degrees in agronomy at Oklahoma State University, he left Oklahoma to complete a doctorate degree as an agricultural botanist at UC Davis.

His specialty at UCD was working with weed management in horticultural crops throughout California. He conducted experiments on plant interactions and plant management and always took photographs (slides) of research to use in presentations and teaching. Many of his images were used in UC publications, text books, and various commercial publications such as Sunset books and magazines and Ortho Gardening books.

Before his retirement from UC, Elmore rekindled his interest in wild animals. He began with a safari in Tanzania, and was fascinated with the animals and scenery—it became his new passion. He returned to Africa (Botswana, Kenya, South Africa, Tanzania and Zimbabwe) multiple times.

Elmore has photographed in Brazil and Argentina in South America and India. In North America he spends much of his photographic time in the northern states and parks of the United States, Canada and, of course, Alaska.

As Elmore looks about his office, he sees images of bison from Yellowstone National Park, African leopard from Tanzania, American badger from Colorado, zebra from Kenya and silver fox from Montana. He has developed wildlife and landscape images as mounted and framed prints.

Elmore has had individual and joint shows at several galleries, fairs or at businesses. Prints have been sold through shows and exhibits. He also has a complete line of animal and landscape greeting cards.
