Glyphosate market drying up

I have also heard the theory that high rates and effective application will make resistance issues worse and faster. Since the only escapes are the most resistant plants. And they are free to propagate without competition. Whereas at low rates poor application, the escapes will be competing with each other.

Could chemical resistance be more about mineral imbalances then the actual chemicals used. The greater the imbalance the greater the chemical resistance

That's why we're walking and respraying with another chem if necessary. And switching to RR can.
Have some ground would get can every second year for a bit if landlord would allow.
Only a few fields, yet.

Our water a big factor I've learned.
AMS or similar in every tank now.

Since you posted it and thought it was worth repeating , explain in a little more detail what benefit this would have for the competing crop or the shape of the field in a couple of years.

Seriously.

This was something I read on Newagtalk a few years ago. You are welcome to look it up and take your feud up with the original author.
At higher rates, you would kill everything that is not resistant, and leave only the resistant weeds behind to procreate.
The random mutation which causes a naturally resistant weed might only be one in 100 million in nature. But if you do an effective enough job of killing all of the non-resistant weeds, then the only weeds left to spread their seeds are the resistant.

Or do you need an entire lesson in how evolution and survival of the fittest works?

Can't remember where or who- Was told reduced rates sped up resistance as only a partial kill and the plant "shook off' the effects and learned "how to deal with it".
Similar to getting an immunization.

Both sides can make convincing arguments. But how does an annual plant pass on the resistance to the next seasons weeds that had to grow back from seeds, if it just shook it off and survived?
Edit. On further consideration, the more we learn about genetics, the more it does sound plausible that organisms can pass on acquired immunity.

We do the same BP
money well spent , and she mixes it up one year to the next
those kangaroo sprayers at half chem rate probably caused lots

Back in the day our Ag shield sprayer worked pretty good and the idea was then to cut rates. It did work but I would agree that resistance comes easier. For me continually changing chem groups on fields works best. A diverse rotation really helps too.

A actually liked the coverage an air sprayer achieved. I never reduced rates beyond 75%. I know many who did. Regardless of sprayer. I remember seeing very stunted weeds, managing to push out one or two seeds before frost. That is definitely resistance selection.

I remember balking at the cost. But I focus on the oat escapes that really slapped you later. I now try to leverage that expense to it's fullest. They can only earn their keep if you put them to work, and work with them.
