I recently received an email notification about a newly identified vineyard disease called grapevine redblotch.
Although this is not really a weed science issue, I thought the symptoms might be confused with other biotic and abiotic problems (such as herbicides). So, I thought I'd share the news brochure (attached below) that Drs. Sudarshana (USDA-ARS, Davis) and Wolpert (UC Davis) put together about the disease.
Here's a link to a related article on the disease in the trade publication Wines and Vines.
Take care,

Before I go out the door for the Thanksgiving holiday weekend, I wanted to share a link to the recent Western IPM Center newsletter, The Western Front.
The October 2012 edition had a really nice writeup about the glyphosate-resistant weed workshops and IPM publications that I mentioned in my October 29 post. The author did a great job summarizing the issues, objectives, and even the IPM publications so I'll encourage you to take a look for yourself.

I received a press release this week from the Weed Science Society of America (WSSA) that I thought would be interesting to repost here.
The statement entitled: Three Leading Scientific Societies Take and Objective Look at the Issues Associated with "Least Toxic Pesticides" Applied as a "Last Resort" was co-authored by the WSSA, The American Phytopathological Society (APS), and the Plant-Insect Ecosystems Section of the Entomological Society of America...

One of my research focus areas over the past few years has been related to soil fumigation issues, specifically focused on methyl bromide alternatives for the tree and vine nursery industry. I described some of this nursery work in a post late last year. Today I wanted to share a brief description and links containing a more overarching view of methyl bromide alternatives related research in California, Oregon, and Washington.
With the support of USDA-ARS, a five-year program was initiated in 2006 to support research, demonstration, and extension projects in western cropping systems heavily reliant on preplant soil fumigation with methyl...

A quick post today to share a link to the recently revised "UC IPM Pest Management Guidelines for Pear" (UC ANR Publication #3455). 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 pear pest management, as well as specific information on insects, mites, and diseases of pears, since this is the Weed Science blog, I'd better post a link directly to the Integrated Weed Management section authored...
