In my presentation I threw out several challenges I see from my own little place in the weed world.

The first one was “can we truly overcome the loss of glyphosate in the U.S.?” While again it is a harsh statement, I believe it is too late to save glyphosate as a herbicide we can build programs around.

Another challenge is having all our weed control technology now tied up in the seed.

I do not believe we fully understand the implications of this one yet. This means our choices in weed management systems could now be determined by what seed companies decide to grow.

Also, you have to breed the seed, increase them, select for high yield and good agronomic characteristics for a broad range of locations and conditions — all while trying to outguess where the weeds will be five years from now.

Another challenge I presented was “can the companies work together to save the technologies we have now?” I believe this is crucial and I have my doubts that they can.

Another challenge is the fact we have pigweed resistance to essentially every current herbicide mode of action and our newest mode of action is 30 years old.

I believe a huge challenge is “can we save glufosinate or Liberty?” If we cannot build programs around glyphosate, we will have to build them around glufosinate. If we lose glufosinate, then we have no broad spectrum platform to carry the new technologies forward.

An even bigger problem may be “can we make enough glufosinate?” It seems as if a lot of folks are having a hard time believing in the potential for glufosinate since it struggled for so many years to find a place.

There were others related to herbicides, but the two largest challenges I presented were “can we overcome the farmer’s complacency toward herbicide resistance (and the belief that the next new trait will be a miracle) and can we change the farmer’s mentality from reactive to proactive weed management?”

If we can accomplish these two we can beat the resistance thing. If not, things will continue to get worse.

While I write a lot of things that may seem pessimistic, I am throwing out the challenge to the farmer to take charge of herbicide resistance on their farms and not depend upon anyone else to provide the magic bullet.
