Below is a recent press release from the Weed Science Society of America (WSSA) announcing a new fact sheet addressing misconceptions about the so-called "superweeds".
I alluded to this few weeks ago in my post "Can herbicide resistance move from crops to weeds?" when I discussed the potential for gene flow from crops to weeds and how that might or might not affect the development of herbicide-resistant weeds. That earlier post was basically the working draft of background information provided to the WSSA committee that developed this new fact...

Methyl bromide fumigation kept the nutsedge in check for strawberry growers, and when methyl iodide came along it was an equally effective replacement, but both of these fumigants are now gone. There are no herbicides registered for strawberry that control nutsedge and in the absence of management tools this perennial weed is doing great in warm fertigated strawberry beds.
Alternative fumigants are partially effective. In fact, they do kill nutsedge very well when in direct contact with non-dormant, germinating tubers. However, they are applied via drip and the further from drip tape you go in the bed the greater is likelihood of weed survivorship. We saw this with VAPAM (MITC-generator, 50 Gal/acre) end-season application....

Sharing the results of two recent field trials conducted to evaluate several POST herbicides with and without the addition of pyraflufen (Venue). Please note that glufosinate is not a registered treatment for prunes - this site was not harvested. The other treatment combinations are registered in most California orchard crops.
Edit 9/24/14: An oversight was pointed out to me on this post from yesterday - I didn't put these results in the context of expected performance.
According to the Venue...
