A quick post today to share a link to the recently revised "UC IPM Pest Management Guidelines for Kiwifruit" (UC ANR Publication #3449). 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 kiwi pest management, as well as specific information on insects, mites, and diseases of kiwifruit, since this is the Weed Science blog, I'd better post a link directly to the Integrated Weed Management section...

Glyphosate resistant ryegrass has been a persistent problem since appearing in almond orchards in the Sacramento Valley in the late 1990’s. It is a winter annual weed, but under irrigation it can germinate any time of the year. This year round germination pattern wasn’t noticeable in the Sacramento Valley when it was effectively controlled by glyphosate. Summer and early fall germinating ryegrass plants are particularly difficult to control at the typical November to December herbicide timings because they are larger established plants at the time of application.
Pre-emergence herbicides are a good way to deal with this extended germination period. June/July pre-emergence herbicide treatments...
Happy New Year!
A quick post today to share an article I wrote last fall for Western Fruit Grower (Nov/Dec 2012) It was in a section called "California Nut Report" which is about California nuts, not by them.. I think). The online, and professionally edited version of the article can be found here.
Nut harvest is over and, barring another dry.../span>
A couple years ago, I posted some statistics on the tree, vine, and berry acreage in California because I find that kind of thing interesting and thought others might too. The bad news is that the book chapter revision that I originally compiled those data for is still not done; however the good news (?) is that I updated those T&V acreage data and I still find them interesting (my two-year revision of that book chapter, somewhat less interesting...).
In the 2011 crop season, the two largest acreage crop groups were tree nuts and grapes. Tree nuts included about 760,000 acres of almond, 245,000 acres of walnut, and 153,000 acres of...
Following up on my post last week about T&V herbicide changes, today I want to focus on hot-off-the-presses information about Alion (active ingredient = indaziflam) manufactured by Bayer CropScience.
Alion herbicide, which was labeled in California tree nuts, citrus, stone fruit and pome fruit was just received a supplemental label for use in grapes. For grapes there is not a range of use rates like in orchards - only 5 fl oz of product per acre (0.065 lb ai/A) is registered and only one application per 12...
