UC Weed Science (weed control, management, ecology, and minutia)

Last entry I talked about the problems with artichoke thistle (Cynara cardunculus L.) in the Sacramento Delta and other coastal regions. Again, this thistle was introduced to California as the cultivated artichoke, but escaped to become a serious rangeland weed.

Part of my job as the Director/Farm Advisor at the Intermountain Research and Extension Center involves overseeing weed management programs for a variety of crops and non-cropland at the Center. Over the last month, Ive observed the outcome of these programs as many of the crops are nearing harvest.

Over the weekend, the Sacramento Bee published an article discussing the invasiveness and spread of yellow starthiste (Centaurea solstitialis) in California. http://www.sacbee.com/2011/08/21/3847369/invasive-yellow-star-thistle-aims.

Today I'm asking for input from folks who work in orchard and vineyard weed control (land owners, managers, pest control advisors, sprayer operators, etc.) on your take on herbicide resistant weeds.

I ran across a Weed Science Society of America (WSSA) press release from last summer that I found interesting.
