Athough not specifically a weed science opportunity, I wanted to repost an announcement for the 2012 University of California Cooperative Extension Horticulture Almond Internship Program. This six-month internship opportunity, sponsored by UC Cooperative Extension and the Almond Board of California, would be a great opportunity for a graduate or undergraduate student interested in research and extension careers.
From the announcement:This paid internship offers the successful candidate an opportunity to learn about and assist with cutting edge research and education programs in tree crop production, sustainable agriculture, integrated pest management, soil and water...

The 2012 Western Society of Weed Science recently published its annual Research Progress Reports. The full set of progress reports are available online at: http://www.wsweedscience.org/Secure/editor/ResearchReports_Archive.asp
These reports generally present data on early-stage and may discuss unregistered herbicides so I should reprint the WSWS disclaimer that "The 2012 Research Progress Progress Report of the Western Society of Weed Science (WSWS) is a compilation of research investigations contributed by weed scientists in the western United States of America. The objective of the Research Progress Report is to provide an avenue for...

The development of improved cultivation technology for row crop production has been an active area of research, and has made significant progress in recent years. Currently, standard cultivation removes weeds from the majority of the bed using sweeps, knives, coulters and blades. Typically a 4-inch wide band is left around the seedline. Weeds in the uncultivated band are typically removed by hand, and the density of weeds that occur there, determines how laborious and costly subsequent hand weeding will be.
There is technology to remove weeds from the seedline and it generally falls into two categories: 1) blind cultivation and 2) computer assisted cultivators. Implements used for blind cultivation are not guided by a...
After writing an article about natural herbicides in the December issue of this newsletter, I was asked what I thought about the iron HEDTA (FeHEDTA) herbicides that recently came on the market. These are organically acceptable products believed to have minimal human health or environmental effects.
My first finding was it’s difficult to obtain herbicides with FeHEDTA in Southern California where I am based, but apparently products are easier to find in Northern California. Of the four nurseries I went to, I found only one that carried even a single product that contained FeHEDTA. The product I found was Whitney Farms Lawn Weed Killer (Scotts), although according to the California Department of Pesticide Regulation’s pesticide...
