CDC study finds glyphosate, controversial ingredient found in weedkillers including popular Roundup brand, present in samples

Probably not being used much on lawns since it is most effective at killing grass. In the Ag world, it's use is becoming less and less, it has become a chemical that you use to kill grasses and that's about it. Became expensive this year and was not used by many people.

If you use that to spray a lawn, you will no longer have a lawn, but ok…

Also big scary "linked to cancer" is all about exposure levels.

If you're bathing yourself in any chemical, you're gonna have a bad time. So it's definitely a concern for farmers who may be around the concentrated chemicals frequently. Lower levels however are much less likely to have issues.

Sounds PERFECT!

Until humans develop an EPSPS pathway, I think we're good.

Insecticides on the other hand - Those should be taken seriously.

I would tend to agree. If one knows any agronomists or those experienced with commercial ag sprayers, herbicides and pesticides are diluted with water to crazy small concentrations. I think most laymen would be shocked at how little herbicide/pesticide etc goes into each acre.

It's true, farming is not rocket science, but these days those in the industry do work very hard at getting the volumes exactly right to maximize absorption and minimize runoff. Now I can see why the chemicals could be dangerous in their bulk form because they are generally highly concentrated in their commercial form.

Improper handling and disposal (you try not to "dispose" any, instead using your entire inventory as it is intended and directed in the field over time) would definitely be where I would look. Improper handling and disposal is a very serious crime, but it is relatively hard to police in a preventative or timely manner. There are tests that can be done after the fact, of course, but obviously that is problematic.

I (not in the industry) also didn't know before this article that glyphosate is often sprayed on wheat before harvest. It appears, from looking into it further, that that is likely one of the biggest sources of glyphosate residue entering the food supply (it looks like corn is considerably less because that mostly ends up on the husk, and I'm guessing the application is earlier in the season giving more time for it to break down).

So if any changes were made it would probably be to change\end that practice.

Oats are another cereal crop where this practice is very common. It helps with uniform drydown across the field. In many areas, a second crop is planted immediately after cereal harvest (usually soybeans) as well so they can gain a few days by speeding up that process to allow for earlier planting.

All chemicals have a pre-harvest interval which is a set amount of time that must be observed between application and harvest of the crop. This varies depending on the chemical - Wheat is 7 days when used for dessication and some insecticides are as much as 60. In a perfect world everyone follows those regulations and we have no issues. In reality, like most things, there are people that do and people that don't.

I really don't like using insecticides or fungicides. Last resort.

Most homeowners have little limited use for glyphosate. It's used for driveway weeds and if you want to kill off an entire area for some reason.

It's from our food supply.

You are correct on corn it's only sprayed when the plants are so small there isn't even an ear. If you are spraying it later than that it's not effective at all. Any weed that's taller than the corn that quickly will be so resistant to glyphosate they'd laugh at you while you are spraying them.

You point out what is a growing problem from routine herbicide use, in that we've created highly resistant weeds.

Perhaps the future is AI robot overlords with lasers zapping weeds.

You say that as a joke but it's been in the works for a long time now. The systems are starting to get really good at identifying weeds vs crops.

Negative all you have to do is switch modes of action. You are an idiot.

 

[AgronAlum]

Negative all you have to do is switch modes of action. You are an idiot.

Until you have weeds like water hemp and Palmer that are resistant to 4 or 5 modes now in areas of the US. I’ve lost count how many were up to.

I was a seed corn guy by trade and I had a lot of high production acres get pulled from production to get weed pressure under control because of resistance to herbicides. The scary part about that is you have to use conventional methods on seed corn because it’s rare both parents are resistant to the most conventional herbicides.

We haven’t come up with new modes of action in a long time. We’re just incorporating new modes of resistance in conventional crops. Eventually we’re going to run out of modes to incorporate resistance into beans and corn.

I agree with you on lawns though. Herbicides generally haven’t been applied enough to form resistance in town.

 

[nocsious3]

You sure about that? Responsible applicators rotate modes of action, yet we still have a growing problem.

Unless you're a farmer or a golf course superintendent, the chances you've applied more applications of herbicides, fungicides, insecticides, plant growth regulators, biostimulants, soil conditioners, or wetting agents is zero.

Agree on weeds in town, but we definitely see resistance with fungus in lawns.

Yup. The tech is getting pretty darn good.

Here’s a question for the lawn care gurus……


With my lawn going somewhat dormant (NC Iowa, was dry, but have gotten a fair amount of rain recently), I noticed a variety of weeds that have sprung up.

Would I be doing more harm than good dropping some 2-4D, probably with some crab grass killer, or would it be better to wait until the weather cools off?
