Buying Glyphosate

Your link looks reasonable.

I know at our local farm and fleet you can buy roundup in the garden section for about 20x what it costs in 2.5 gallon jugs!

I have a farmer friend that buys in bulk, I think I pay him about $8 a gallon.

Go to local ag chemical dealer and buy 2.5 gallon jug. I believe it is 41% gly. Various names. Mix your own. Easy.
 
I pay $9-$10/gal for a 30 gal drum of 41% gly at the local coop.
 
Is 32 oz. gly per acre correct?
 
Everything depends. If your doing a small area only you may be ok getting ready mixed but it is certainly cheaper to purchase a concentrate (most usually the 41%) and tank mix your own. When mixing your own make sure to follow the guidelines for the specific % you purchased.

I don't buy it by the brand name. As long as the label on the jug reads "Glyphosate" as the active ingredient - your in business. Read and follow the label as some come in different concentrations. Also keep in mind that the stuff in the lawn & garden section tends to be weaker stuff, while if you can get to a farm/ag type retail store and go back to the ag chemicals you can get stronger stuff in larger volumes for a better per unit price! Where I buy mine....I can buy it by the gallon, 2 1/2 gallon, 15 gallon and 55 gal drum if I want (I could possibly get it in the 275 gallon totes but that would be a lifetime supply for me). We habitat types toss "Round-up" around as a generic term most of the time..... When you store it do NOT let it freeze - it pretty much renders it useless. As long as you keep the cap on anything left in the jug it will last and keep on a shelf as well.

Rural King is almost as perfect a store for us habitat guys as I have found! I have 2 stores within 15 minutes drive!!! One of the perks to living in farming country.
 
Generic 41% glyphosate mixed at a rate of 2 quarts per acre will give you a Great burn down. Buy it wherever you can get the best price. 2 1/2 gallons will normally run about $35-40. Thiessens, Agri-supply and internet are some great places to start. Check late winter and early spring for the best prices.
 
Yes, the drexel has surfactant in it which is good, the other one doesn't list it.

It depends on what you are doing and what you are trying to kill. The nominal total kill rate is 2 quarts per acre of 41% gly. It is best to calibrate your sprayer.

The Drexel stuff is what I tend to get.....but I look for 41% glyphosate first...

How much you use will depend on different things. All those pages on the product label is where all that stuff is at. Spot spraying typically is roughly 2% (2.7oz/gallon), while boom type spraying can be as little as 8oz per acre to as much as 32 or 48 oz per acre, while stump treatment or basal spraying is even a higher concentration. It all depends on the weed, how mature it is and the application method.

Now, I will be honest. I cheat, because I am lazy. I use a 2%+ solution all the time and it seems to handle most of what I need. I mix 1 1/4 gallon of gly into my 55 gallon sprayer and spray away! I typically buy a 2.5 gallon jug of gly and I simply divide it in half between 2 tanks/trips. I am sure sometimes it's too hot and sometimes it's not as strong as it should be. It however tends to do what I need or at least a good enough job. There are several variables that come into play when spraying a large area (nozzle rates, number of nozzles, travel speed, spray width.....). The only time I figure it out down to pretty darn close is when I am dealing with a far more costly chemical. Gly is about the cheapest chemical I buy ($32 for 2.5 gallons is pretty cheap compared to some). Some will look down upon my methods, but I live on the property, the chemical is cheap and I can get more gly in a 30 minute drive and be back spraying if I need to.....shoot me.

Glyphosate is an example of a very stable herbicide. Although glyphosate freezes, after it thaws it goes back into solution. ... glyphosate has a long shelf life, and is not affected by freezing.

I've have let my leftover gly freeze every year for the last 10+ years, no problems. Temps here get down to -40 actual, not windchill.

I remember when I setup my herbicide locker finding a list of herbicides with minimum storage temperatures. I wish I still had it to post. I use a small oil filled heater in an old box from a reach-in cooler. It keeps the temps in the cooler well above freezing in the winter. While freezing doesn't seem to affect most glyphosate products, it does affect other herbicides. I say "most glyphosate products" because I recall coming across one manufacturer that recommended not letting it freeze. It may have to do with the particular surfactant they used or something rather than the gly itself.

Thanks,

I have had issues.....I refuse to let mine freeze. Maybe I got a bad batch or something, but I have had poor results with gly that has frozen and then been used before.
 
I buy it as 41% gly, generic name Buccaneer. I get it in 2.5 gallon jugs, two jugs to the case from a local ag chemical supplier. I have filled out the WI farm sales tax exempt form so I do not pay the 5.5% state sales tax. If I recall correctly, I paid $54 for a case last year. I have a 55 gallon Fimco pull behind PTO sprayer. A 2.5 gallon jug mixes exactly with 50 to 55 gallons of water to give me the concentration level I need. I believe in doing a job right the first time around. I try to use up what ever I buy the season I purchase it. If I have any left over I simply keep it in my basement over winter.
I did calibrate my sprayer before the first time I used it to spray large fields so that I know the exact RPM I need to be running for efficient spraying.
 
What do you guys buy?

Roundup is pretty expensive and only 1-2% glyphosate. Do you buy concentrated fly and mix it yourself?

How about this:

You're from Ontario, am I correct? You can not buy Roundup concentrate unless you are farmer or have a pesticide license.
 
I am from Ohio. I have a house in Ontario. I guess I will buy it here and take it up with me. Thanks for the heads up.
