Have some 2+ years old. Still good?

I have some that is closer to 5 years old and it still kills weeds.

Double up on the dose ?

Fk pesticides...
A mix of distilled vinegar, Epson salt ams liquid dish detergent kills just as well and doesn't cost but a 10th to make. Plus your not funding Monsanto.

RW:

Have you actually run the calculation of the cost of the vinegar concoction versus a 46% glysophate?

ringworm, I just read about vinegar weed killer the other day.
I'm gonna try that.

There are several other brands of glyphosphate besides Roundup - most of them less expensive and with the same exact ingredient. In fact Monsanto also makes another brand that is roughly half the price of their own Roundup.

Just make sure it is the 41% or better concentrate rather than the diluted grade sold at retail stores. It only takes 1+1/2 to 2 oz. per gallon of water. so I doubt there is that much savings using a vinegar mix.

As to shelf life, I have read that it is good for many years.

Yeah, but most of that stuff is edible. Doesn't matter that it works just as well.

Roundup is a herbicide.

That means it kills plants.

I'm glad someone pointed that out

Glyphosate will keep for many years, I buy it in 2.5 gal jugs & use it for years. Go to any co-op, farm supply, or tractor supply company & get the generic 41% stuff in 2.5 gal. It goes up & down in price but sometimes I've found it for around $30. Mix it at 2-4 oz. to the gallon & it'll go a long way.

We use something like 70-100 gallons in a season.

Also it goes into a 25 gal tank and a 40 gal tank on John Deere "Gators." Use it to spray ditches and in the pecan orchard. Got to be careful in the orchard,want little to no wind when spraying.

Weeds are a pest. The term "pesticide" is a catch all.

No,pesticide kills insects not plants.

Insecticide kills insects.

And that is a pesticide.

Si.

As are herbicides. And fungicides. And miticides. Yada yada yada.

Herbicides kills plants.

So,when it's time to kill spider mites I'm supposed to buy a herbicide like Roundup?

All insecticides are pesticides. Not all pesticides are insecticides.


Logic classes are fun. Carry on.

You'd better let the Fed and the State of Texas know about this. Seem they consider herbicides and insecticides BOTH a "pesticides".

At least that was what we were taught in "Pesticide Applicators" license school last year.

"What is a pesticide?
A pesticide is any substance or mixture of substances intended for:

preventing,
destroying,
repelling, or
mitigating any pest.

Though often misunderstood to refer only to insecticides, the term pesticide also applies to herbicides, fungicides, and various other substances used to control pests.

Under United States law, a pesticide is also any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant."


Prize goes to ringworm, higbean, and cheesy.

The ignominious recognition for getting his 2 cents in incorrectly once again goes to elkhunternm.

Not to worried about Texas,but the Feds.....

What I was taught in the same school was "read the label."

Without googling most people I know consider Roundup to be referred to as a herbicide.

Pesticide is for non-plant life.

It is a herbicide. It is a pesticide.

Back to the original question -- it lasts like gunpowder. Keep it cool but not froze, in original jug. And -- buy in bulk, the "glyphosate" stuff is what you want.
You want 40 plus percent, and mix it down to 2 percent gly to have the final mix. Helps to have a nice graduated measuring cup and a calculator.

Had about a third of a bottle of glyphosate in the shed over the winter before last and with our winters you know it froze quite thoroughly. Worked just fine last summer.

I mix glyphosate at the middle label rate with homeowner-type broadleaf weed killer (Trimec), again at label rate. Between the two all dies quite nicely, there is some resistance to glyphosate building up in some weeds around here.

I don't give a fk what you want to call it. I'm on a well and I have fruit bearing trees and a garden. I'm not putting poison In around or on my peppery.
Npow back to your tomato/tomato arguments.

Anti-business socialists are against companies like Monsanto. The risk for you is worth the reward for them.

Yep, it might not be so smart in your deal, don't you have like half an acre and probably a shallow well.

I'm not seeing glyphospate getting almost 550 feet down in one of our wells in enough concentration to be of an issue....

Glyphosate (the active ingredient) binds readily to soil particles. Guys who fill their sprayers from farm ponds often have problems with reduced effectiveness because of that fact. So unless you pour the stuff down your well, it won't get there through the soil.

Your fruit trees should be fine unless you drench them with spray. Generally in forestry, hack and squirt is the procedure, hack a big gash (or two) in the bark and spray with undiluted herbicide.

I'd stay away from the garden but IME, your fears are baseless.

I have stuff thats 20+ years old and it works as adverstised.

Better not eat any corn or corn products because most farmers spray with Roundup ,which is what it was initially created for.

Roundup is bio-degradeable. Strickly a contact herbicide. You can spray it on weeds and in4-6 weeks plant that field with no problems

You can spray Roundup and then plant in 4-6 MINUTES
I often see planters being run right behind the sprayers

Aaaaaaaand here is where we take the GMO twist with roundup ready seeds.....

I'll be 79 my next birthday and I'm still working.

ROUNDUP

I was at the Monsanto plant 20 years ago. I wanted it to have residual for a week or two and they said it was not possible because once it hit the ground it was done. We plant immediately after spraying the feild if necessary with no effect. ED K

For years I worked for a seed company doing research on watermelons & squash. We knew to the day when the new plants would start to emerge. We'd plant, wait until the day before emergence, then spray. The new plants would emerge through treated soil with no damage whatever.

Years ago I got the bright idea of using roundup on asparagus. I cut EVERY stalk below ground level and covered over the stump with dirt. Then I sprayed. That didn't work and I still don't know why but I had to replant. For asparagus, use a mix of 2-4-D for broadleafs and Sethoxidone (Poast) for grasses.

I dont.
I don't eat corn or wheat or any other grain or lejume.
Nor do I consume prossesed sugar or chemical sugar substitutes or products containing and derivatives of those.
That's why at 45 I'm a ripped up, bad azz MF and 90% of guys my age are slobs.

For the little bit of asparagus I have I spray early, putting an ice cream pail over the plant and spray away. Late season when its ferned out and the stalks are hard I've sprayed gingerly keeping the spray nozzle as low as possible. It worked but I would not recommend it. Glyphosate is absorbed typically through the leaves. Was betting the stalks had hardened enough to not absorb the stuff and I lucked out. Guessing in your case the cut ends absorbed enough before the glyphosate had time to bind with the soil.

Glyphosate isn't a poison either! The LD50 is too high for it to be labeled as a poison. Most pesticides that are poisons have a skull and crossbones on the label, like Gramoxone ( a herbicide) and Vydate (an inseciticide).

BTW, I do believe Monsanto makes most of the glyphosate, whether sold under their own label or another chemical company's label. Monsanto used to make a "generic glyphosate" for DuPont to sell under their own label.

This thread has reminded me I need to swing by the farm store on the way home and pick up a 2.5 gallon jug of the generic concentrate as well as a jug of 2,4-D for dandelion patrol. Rigged up a boom on my 4-wheeler and a 25 gallon sprayer tank, makes the yard weed free. Wife complains about wind drift of 2,4-D to her petunias though.....

Now you are sounding like squats to pee............

Ed is correct. EPA considers both herbicides and pesticides to be "pesticides" from a regulatory perspective. Their regulation goes to the issue of approval or denial for purposes of marketing.

Call it whatever you want.

It will be fine
