Aaron Hagar presented information about herbicide resistant weeds. This a subject I have discussed several times before on here. he showed a chart with a recent study that shows that some weeds have triple resistance to ALS, PPO and Glyphosate herbicides. Mechanical weed removal may need to return to the arsenal. It would also be a good idea to plant liberty link crops on your weediest fields. I think we can continue to use roundup if we rotate it with other herbicides and or use it in tandem, but I would try to set it up so that roundup is my rescue treatment and not the primary herbicide. Also, sharpen the hoe and go get those last weeds that you do not kill manually.
