Despite the fact that I am currently working in orchards and vineyards, I receive lots of requests to discuss Palmer amaranth (Amaranthus palmeri S. Wats.), a weed that I spent almost six years studying. It's the scourge of the Southeastern United States - and a weed that I think everyone should be (or at least become) very conscious of.
Considering that Palmer amaranth is starting to rear an ugly head in California cotton and perennial cropping systems, I thought that I might start a series of blogs revisiting some of the research that I was a partner to in Georgia.
First things first, though...what is Palmer amaranth?
Palmer amaranth, also commonly known as careless-weed (because it can get away...

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.
Take care,
Brad

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...

Today, instead of posting something about weed control and herbicide resistance in orchards and vineyards, I thought I'd go out on a limb and discuss weed management and herbicide resistance in... alfalfa! (Yes, it gets a little wild around the holidays at UC Weed Science...)
Anyway, while working on some articles for an upcoming volume of the California Weed Science Society Journal (CWSSJ), I was reminded of a really nice UCANR publication "Avoiding Weed Shifts and Weed Resistance in Roundup Ready Alfalfa Systems" by S....

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...
