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...

Happy Halloween!
Today I wanted to follow up on a previous post on the phenonena of enhanced microbial degradation of the residual herbicide simazine in orchards and vineyards. In that post, I described research that we did a few years ago to address faster-than-normal degradation of simazine in citrus orchards.
The results of concurrent study done in raisin vineyards near Parlier was published in the most recent issue of the journal Weed Science. Unfortunately, that journal is not open-access but academic folks can find the article under the citation Abit, Rainbolt, Krutz,...

Last winter, I particpated in a series of seven half-day workshops in California, Oregon, and Washington on herbicide-resistant weeds. These workshops were organized by Kassim Al-Khatib from the Univeristy of California Integrated Pest Management (IPM) Program and had a special focus on glyphosate-resistant weeds in tree and vine crops.
In preparation for these workshops, we wrote a series of extension publications that I wanted to share today. The publications and resulting presentations were prepared by weed scientists from various Universities, Cooperative Extension, and USDA-ARS and included various aspects of herbicide resistance in permanent crops. Even as somone who thinks about herbicide resistance...

Today I thought I'd share a recent research report on the the phenomenon of "enhanced" degradation of the herbicide simazine in citrus orchard soils. Click here for a link to the publication in the open-source journal, Air, Soil, and Water Research (Abit et al. 2012. Air Soil and Water Research 5:69-78). The lead author was a UC Davis post doctoral researcher and her coauthors include UC Davis, USDA-ARS, Fresno State, and UC Cooperative Extension folks.
This work was started several years ago in response to some questions from San Joaquin Valley orchard and vineyardists poor weed control with simazine. They suspected herbicide...

The Annual Bluegrass Pest Notes has been revised.
If you're not familiar with Pest Notes, they are the University of California’s official guidelines for pest monitoring techniques, pesticides, and non-pesticide alternatives for managing pests in homes and landscapes. Pest Notes are authored by UC folks and produced by the UC Statewide Integrated Pest Management Program. Best of all, they are FREE!
Here's the link to the weed-related Pest Notes: http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7464.html.
