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...

I was forwarded a question recently about rotating herbicide mode of actions for resistance management in vineyards and realized that the information is not always particularly easy to find. We are planning to include site of action information in the next update of the Herbicide Susceptibility Chart; however, it is not available on the current version (http://info.ucanr.org/weed_sept/).
In the meantime, I updated the T&V herbicide registration chart from a few weeks ago with herbicide site of action groups according to the Herbicide Resistance Action Committee (letter/number) and Weed Science Society of America-WSSA (number) systems. There is still some debate about the...

Although many orchard weed managers are waiting for rain (or at least a chance of rain) before putting out their dormant-season herbicide applications, I thought I'd post a few results from three 2011 residual herbicide trials focused on hairy fleabane.

Field experiments were conducted in an almond and walnut orchard near Davis, CA and an almond orchard near Arbuckle, CA to evaluate premium residual herbicides plus burndown materials for dormant season application in tree nut crops. Several newer materials were compared to grower standards for their relative efficacy against hairy fleabane and a wide assortment of winter and summer...

One of my major areas of research the past few years has been related to alternatives to methyl bromide fumigation in perennial crop nurseries. A list of recent posts on soil fumigation research and issues is available. Some specific research areas have included reducing atmospheric emissions of methyl bromide alternatives and on alternative fumigants such as methyl iodide.
Today, I thought I'd share some basic information on the nursery cropping system as well as two recent...
