Weeds Becoming Roundup Resistant

There's too many people that have only used roundup without mixing up modes of action and throwing different products at the weeds at times. When roundup is the only chemical used for 15 years on the same soil, a person is going to have problems.
We have a little bit of waterhemp that is resistent but nothing serious. You see a lot of other people with bigger problems around. Their agronomist wasn't giving them good advice.

I just want to point out that this is in no way Round Up's fault. People are using it too much and naturally selecting for weeds resistant to it.
That's not really true. The majority of agronomists would still prefer a pre emerge followed by roundup program and it has been like that for quite a few years. Just because the grower didn't do it doesn't mean the agronomist didn't recommend it. It was more expensive by a significant amount and people didn't want to spend it when they could go all roundup super cheap. I would also argue that a larger problem was misuse. If roundup was labeled at 22 oz. (which it shouldn't have been) then there were a lot of guys putting on 16 or 18 to save a couple pennies. Another issue was the idea that generic glyphosates were the same thing. They weren't. Those things should have been used much more liberally than they were.
My argument is that misuse of the product carries the same blame, if not more than the mixing of modes. Now we are to a point where we do have to mix up modes because there is resistance to many of the products in the market.
I think it should have been labeled more strictly and marketed more truthfully than it was. That is where I will end blaming the manufactures though.
It's really not a big deal in Iowa. Buy a mix, different modes of action, and you will be fine.
The chem companies will come up with the next big thing to replace generic glysophate too.

Keep repeating and hopefully people will listen again.

If Monsanto would have put their money into Dicamba resistant soybeans it wouldn't be a problem. Your mode of action would change with each crop rotation. Roundup Ready is amazing technology. It allows us to use a lot less dangerous chemicals. You think the hippies would be happy with that, but no...
So, people who don't like toxic chemicals in their food and water are somehow "hippies" now? I guess I don't understand what the heck you're complaining about with that comment. Who's complaining?

The Roundup system has kept farmers from using a lot of more toxic chemicals. That's a good thing?
Roundup has allowed there to be much less chemicals applied to farm ground. Old methods (before roundup) probably caused a lot more unsafe chemicals to be found in water.
I think the "hippies" comment was more related to the people that just make up conclusions without any evidence or knowledge of agriculture or how food production works. These people don't understand that farmers are growing much more food with less resources and pollution than ever before. If you want things to all be 100% organic with no chemicals ever used, MANY MANY more people in the world will starve.
Its not a big deal in Iowa YET. I have no doubt that at some point we will be battling the same resistance in Iowa that they have in the South right now.
Roundup was a great invention and allowed producers a cheap, easy way to reduce and eliminate the need to tank mix chemicals that were in most instances less successful controling weeds. However, continous use of the same chemical year after year no matter what the chemistry is naturally selecting for resistance. The argument of using a different MOA is valid however there are fewer and fewer chemicals on the market because Roundup was so easy.
There are ZERO new modes of action on the market, havent been since like the late 90's. Weed resistance is here to stay and will only continue to get worse. At some point there may very well be a new MOA but until then management of resistance is the best and only real tool that we have.
Exactly...
Its either feed everyone or go chemical free right now... You can't have both.
I work for a Monsanto competitor but from a business standpoint you cant argue with their success when it comes to Roundup. (Ethical issues aside).
Its not Monsanto's fault that they came up with one of the best inventions to hit ag since the synthetic fertilizer. Management of the product and monoculture crops (corn and soy only) is the culprit.

No you wouldn't. You already had that anyway. Corn is already Dicamba resistant so how would making beans also Dicamba resistant help the problem? Why do you think there is next to no Dicamba resistance?
1. Because the chemical is extremely volatile therefor people don't want to use it
2. Because it could only be used so much.
There were enough chemicals to control weeds just as well, if not better than ROundup before Roundup was around. The problem was that it wasn't convenient. In the end, the convenience of roundup is what hurt it.
There is also a difference between tolerance and resistance. My opinion is that everything isn't resistant in Iowa, moreso tolerant. That will lead to resistance.
Roundup will always have it's place as a grass killer in corn. In soybeans, however, it will lose it's place when you have to start spraying the Cobras and such as well as something for your volunteer corn.
Completely agree, Roundup was the cheapest, easiest way to control weeds. Roundup will become one of many chemicals available for a few target species and will be part of a tank mix instead of the one and only chem applied.
