The risks of GMO herbicide-resistant crops as a source for resistance traits in weeds has garnered recent attention in discussions of so-called “superweeds”. [I've commented previously on my general disagreement with the term "superweed" when talking about herbicide resistance]. Some media reports and online sources have suggested that herbicide resistance can be caused by resistance “jumping” from the crops into weeds. In fact, at least one online dictionary defines the problem in these terms:

Intra Row Weeding Machine Demonstration
Wednesday, July 23, 2014
9:00 to 10:00 a.m.
USDA East Alisal Research Station
1636 East Alisal Road (follow signs)
The area of mechanical weed control is developing rapidly in Europe. This machine is designed to remove weeds in the seedline. This meeting is a good opportunity to view this technology and see if it fits your operation and weeding needs.
Topics:
- The Robovator (Poulsen Engineering, Denmark) intra row weeding machine will be demonstrated in a field of transplanted lettuce
- The machine uses a split...

Link today to the newest edition of an important reference book for herbicides - the Weed Science Society of America's "Herbicide Handbook". Dr. Dale Shaner took on the updating and revision of the 10th Edition (at over 500 pages of very dense information, this was no small task!).
This resource is fantastic and is the one reference book that I use nearly every day. Mine is always within arms reach in my office. Take a look if you routinely work with herbicide active ingredients - there is a tremendous amount of herbicide info...
