Good news for POST weed control in several tree crops.
With a recent label change, Rely 280 is now registered for use on citrus, stone fruits, pome fruit and olives.
This is also true for all the currently registered glufosinate herbicides which brings conformity among the products with that active ingredient (there was some oddities for a while in that the newer products has slightly broader registrations than the original product their labels were built upon).
Currently registered tree and vine crops include:

A quick post to share a really interesting website created by the USGS National National Water-Quality Assessment (NAWQA) Program. This site creates pesticide use maps showing geographic distribution of estimated (or actual use in California) of several dozen pesticides on agricultural lands for major crops.

The website introduction states:
The pesticide-use maps provided on this web site show the geographic distribution of estimated use on agricultural land in the conterminous United States for numerous...

Pop quiz.
Today's post is a) long, b) recycled from another use, c) of high interest due to current weather conditions, or d) all of the above? The correct answer, I think, is "D" all of the above.

Ok, this is actually an article I prepared for the meeting booklet for the Plant...

It's that time of the year when we're planning preemergence (aka "residual") herbicide programs for orchard and vineyard crops in California. Typically, these are the herbicides that are applied in the fall, winter, or early spring BEFORE weeds emerge (preemergence) and they usually affect weeds as they germinate or are just beginning to emerge from the soil. [often, people mistakenly think these herbicides kill seeds or sterilize the soil which is not actually the case].
As you're planning the specific program for the weed problems in your orchards and vineyards (or any site, really), I thought it would be a good time to review some of the...

I was forwarded this great article written by Barry Tickes, an Area Agricultural Agent with the Yuma Ag Center and part of the University of Arizona and Arizona Agricultural Experiment Station.
With Barry's permission, I've posted his explanation of "lift off" or "codistillation" of herbicides. The article and other is in that issue of Vegetable IPM Updates can be found
