That is a study on an ingredient that's not in this product.

Before everyone jumps on this because the name Roundup. Roundup is a brand name not glysophate. Roundup no longer contains glysophate. I'm not advocating nor disparaging this product. As a licensed pesticide applicator I just hate to see all the irrelevant studies and misinformation people immediately post about glysophate when they see/hear the word Roundup.

Read the active ingredients of this then read the article. The article is irrevelant to Roundup as it contains no glysophate.

This is the FAKE REFORMULATED RoundUp that uses Triclopyr,Triethylamine Salt,Fluazifop-P-Butyl,Diquat Dibromid.
This IS NOT THE ORIGINAL RoundUp that uses Glyphosate!!!!!
The Fake version WILL NOT provide broad kill as sure as Original version!
Bad Deal!!

If you look back a dozen years, I have responded on SD many times to glyphosate and PFAS deals, and I explained why. I really don't like the looks of this "new" formulation, as several of those chemicals are ones I recognize as having very direct effects on human health. The problem with glyphosate is with the original EPA certification.

That was as a pre-seeding treatment in fields about to be planted. If you are drilling in the seeds, this means you will kill all the weeds germinating from seeds near the top of the soil, without tilling which reduces soil carbon and health, and pulls up weed seeds buried deeper. For that one application, there wasn't much of a problem.

But then they noticed some weeds developing resistance. They tracked down the gene and inserted it into the crop genome. Now you have "Roundup Ready" seeds, and those patents are what made this a hugely valuable chemical. But that use case is totally different. Most Roundup tolerant crops will be sprayed before, or just after, planting. Then there will be 2-4 applications.

But farmers are clever, and I think it was in the 1980's a Scottish farmer used it to kill all his barley or oats just before harvest. WTH. Well, you see the seeds dry out once the plants die. This occurs naturally, but there is variation. That way the plants can evolve to respond to changes in the seasons. But that means some seeds are always less or more ripe. But if you have a good weather forecast, spray your field at just the right time and all of the seeds are dry. You cannot wash them for this application, as washing grain whose plants you killed just to get them dried out in time means it would be pretty stupid to do that. Ergot is a NASTY fungus that can make grain toxic, as in a neurotoxin that effects the central nervous system.

As a last factor, most pesticides and herbicides contain adjuvants. Those are chemicals that make them work better. For example, many weeds have a waxy layer that makes it hardy for chemicals to get inside the cells. An adjuvant strips that layer off. Now realize something harsh enough chemically to do that is going to end up in your gut. Your entire intestinal system has it's own lining to keep you from digesting yourself. There are all kinds of fun chemicals used as adjuvants, and getting the info to evaluate those risks can be difficult.

So we've gone so far from the originally certified use of the chemical that we can no longer see the coastline. 90 plus percent of your groceries have at least trace levels of glyphosate. THAT was not part of that original EPA certification. Add in the issue of adjuvants, and glyphosate no longer seems quite so innocuous. Then add in the farm worker issues, because they can end up in those fields where they get exposed to levels not even imagined originally. Like PFAS chemicals, the more they are used, the risks accumulate.
