Most cost efficient weedkiller?

[JDgreen227]

The premixed stuff sold in stores is basically so weak and watered down I never buy it, instead I go to TSC when they are having a sale on a gallon of 50% glyphosate (sp?) weed and brushkiller mix, then use an ounce or an ounce and a half of that per gallon of water. The gallon costs about $60 even on sale but I can get at least 80 gallons of spray out of that $60 gallon. If anybody knows of a more effective weedkiller that costs less please tell us what you use and where it can be obtained. Thanks.

You have the right idea, but better prices can be found on the internet...

Yes you are right, but I try to support local businesses when I can and TSC is one of my favorite local stores. Appreciate that information and will keep it for reference for when my gallon from TSC is gone.

That's a great deal jbar. TSC's store brand "Big-n-Tuff" is another excellent value. It has surfactant mixed in and it can't get anymore concentrated. I mix it 4gal at a time in a back pack sprayer and go through about one 2.5 gallon bottle (of concentrate) a year. My place would be a jungle with out it. OOPS late post.

I use the TSC 50% glysophate around my prop to keep the kudzu at bay, and it does the trick. I tried some other herbicides (fancier ones, 'tree-friendly' ones, etc) and the 'zu just laughed at them. It doesn't laugh any more...:thumbsup:

But, as you know, glysophate kills everything...'broad-spectrum' doesn't begin to cover it. Be careful where you spray and which way the wind is blowing.

EDIT: that HD link is a great deal! Thanks for posting it!

JD -Home Depot, on line only with free shipping sells a weed, grass and brush killer for $34.00 or so...It is called " Compare and Save..." that is for 2&1/2 gallon of concentrate and it is 41% glycophosphate

I have used it for 2 yrs. now...It kills everything for 1 whole year...I love it but it does take 2 or 3 wks to kill since it kills the roots not just he green leaves...

Thanks Brin...what amount of the HD stuff do you use per gallon?

JD - First let me correct the brand name ...it is ( Compare N Save ) so when you do your search on Home Depot it will be correct.

1&1/2 oz. per gallon of water..I followed that exact one and one half ounces to the gallon and I use a 15 gallon tank sprayer ...it really works great...On the label they claim 3 to 4 days to kill...It wilts in 3 to 4 days but I promise you after 2 or 3 weeks it is dead...dead and dead for one full year...that has been my experience...

Wow, the concentrated glyphosate containers are gettin' cheaper all the time. I bought the 2.5 gallon Big N' Tuf version at TSC for $50 or $55, & see that it's now ~$40. For HD to have it for $40, man it's really comin' down now.

I mixed mine in my 25-gal sprayer & traveled my 3,400' fenceline in my Mule spraying the entire way. Would be a little easier with someone else driving, but still worked very well. Prob took an hour. Took 3-4 weeks for everything to be really dead. Will have to look to see what mix I used.

Maybe the stuff is coming from China now...

I've got a 2.5 gal jug of the Home Depot stuff coming. Second order, as UPS damaged the first one in transit. Wish they carried this at the stores, had to order another additional item that I didn't really need to make up the free shipping minimum. Still, a tangible $8 item trumps $12 shipping.

I read up for a while on getting goats to love kudzu.....:licking:


...haven't screwed up the courage to take the plunge yet, though.

Here is a link to the stuff, but they put it on sale once and a while,GlyStar Original Herbicide Weed, Grass Killer

But, as you know, glysophate kills everything...'broad-spectrum' doesn't begin to cover it. Be careful where you spray and which way the wind is blowing.

For broadleaf control, 2,4-D is pretty cheap and effective, and it won't kill grasses. For woody plant control, triclopyr (Garlon) is pretty popular. Crossbow is a mix of Garlon and 2,4-D, but like any name brand herbicide is more expensive. You can mix your own, 50/50 triclopyr and 2,4-D and it will do a great job on blackberries and underbrush without killing grasses. Spring is the is the time to apply broadleaf herbicides. They don't work well in the fall. Glyphosate will give better results in the fall.

And yes, be careful with 2,4-D around sensitive plants like grapes. 2,4-D is volatile, and a hot day will cook a fresh application back into the air, where it will drift with the wind. I know a farmer who severely damaged a vineyard next to his barley field. That was a very expensive mistake.

 

[JDgreen227]

My main use for weedkiller/grasskiller is for areas around buildings, driveways, walks and fences, plus a few flowerbeds and a garden plot thrown in. I don't so much have a problem with weeds as I do with quickgrass and crabgrass. Even straight 50% glyphosate doesn't seem to kill the underground roots of those two grasses.

 

[DKCDKC]

My county and others have special multi-flora eradication programs in which they give away coupons for Crossbow at better than 50 percent off. I've got a half gallon left from two gallons I got three years ago. I wonder how long it remains effective? Anyway, it might be worth it to check with local and state agencies to see if they have any programs that would cut the cost of a weedkiller.

The most cost effective weed killer I know of and use is vinegar. Cheap white vinegar with a tablespoon of salt and a squirt of dish detergent for every gallon. Costs $2.50/gal. Less if you can buy it in bulk or on sale. Use it full strength.

Warning: This is non-selective and kills everything. I use it to clear garden plots, and you can plant 24 hours after spraying. Best thing is it's much safer than most of the other chemicals and I feel a whole lot less concern about it contaminating ground water.

If I want to kill poison ivy and keep the grass, then I use 2,4-D, but for total weed and grass annihilation, I use the vinegar.

Containers of glyphosate (aka RoundUp) concentrate mentioned in this thread can be readily obtained for significantly less than that.

By your figures, my 25 gallon sprayer full of weed killer would've cost me $62.50 (25 x $2.50), whereas I only paid $50 or $55 for the entire 2.5 gallons (320 ounces) of concentrate, & I only used somewhere between 10 & 20 ounces of the concentrate for my 25 gallon mix (can't remember exactly how much now).
