I led a team to develop a weed identification wheel for use by people who don't have a lot of background in weed management. Since space was limited, I had to narrow down the list to the top 12 weeds in landscapes and gardens and to do this I presented a longer list to people who do work with weeds in San Diego. We came up with the following: yellow nutsedge, stinging nettle, annual sowthistle, bermudagrass, black nightshade, clovers/medics, crabgrass, oxalis (woodsorrel), dandelion, poison oak, purslane, and spurges.
Now before you start commenting that these are not your top 12, recognize that these are what many professionals and home gardeners in San Diego area do consider problematic. What I...

Greetings all. I'll get back to some serious posts, soon. However, I thought I would celebrate the turning of the seasons with song. Nerdy songs. Songs only a scientist could love.
FYI, some of these come with annoying commercials that you need to skip...Enjoy.
First, near and dear to a weed scientist's heart, "The Wild Radish Song". To the tune of "Somebody I Used to Know".

For the graduate students, a Lady Gaga parody "Bad Project".

It is not always easy to kill weeds with herbicides for several reasons, but if you apply the right material at the right time to susceptible weeds you expect control. But you should never assume it, because resistant weeds rely on this assumption.
Repeated use of herbicides with the same mode of action (usually the same target site within plant) selects for naturally occurring resistance traits in weed population. The few resistant weeds proliferate since there is no longer competition from susceptible types and if other control measures are not...

I'm at my desk today catching up (slightly) on things that accumulated during the past few months when it seemed like I was in meetings more than I was anywhere else. I thought I'd share a few thoughts on one upcoming meeting to put on your "I should think about attending" radar as well as three recent weed science meetings.
For your radar:
Weed Day 2014 at UC Davis will be held on July 10, 2014. I'm the chairperson for this year's Weed Day, the 58th annual Weed Day by the way. At this point, the program is a work-in-progress, but will have a similar format to previous years. We'll start off with a...

Project Background and Position Description:
We offer a post-doctoral position to work with the RES Rice Breeding Program in screening and evaluating tolerance of rice germplasm and available mutant populations to herbicides for weed control in rice. The successful candidate will be responsible for developing and testing screening protocols for different herbicides in the lab, greenhouse and rice field, as well as develop additional mutant populations using chemical or...
