Weed Killer Recipes

[jeffinsgf]

I just want to add to this thread that when you use "homebrew" recipes, like salt and vinegar you are NOT being environmentally concious or minimizing your impact on your property or animals. Glysophate has far, far less residual effect than salt or vinegar or diesel fuel. In fact, you can replant within days of a glysophate treatment. Other than tracking muddy prints through the house, your animals would see no effect from walking through a sprayed area whatsoever.

The message in this thread that everyone needs to carry away with them is the fellow who plowed salt into his granny's drive and killed the grass another 10 feet either side of the drive. It will be years before that area will grow grass again.

Using glysophate to control active weeds in dormant stands works, but you have to be very careful. I have a fairly new zoysia lawn that had a lot of fescue clumps in it last winter. In early March, while the zoysia was still very brown, I mixed up a tank of glysophate to knock down the fescue. I started out using the gun, but noticed that I was going through a bunch of mix, so on the second half of the lawn, I used the boom. On the half where I used the gun, the zoysia was stunted for weeks -- brown circles everywhere I pulled the trigger. Where I used the boom the fescue and weeds died and the zoysia greened up nice and even and right on schedule.

Morals of the story are, "Dormant is a relative term" and "It takes a lot less glysophate to kill stuff than you think it does."

If you want to get rid of this stuff you have to get serious. I got some ag type round up from my uncle who is a farmer and the stuff is like a golden syrup. Basically the same color as the Lowes round-up but it looks very diluted. Funny if I double up on the Lowes version mix it works twice as fast and kills everything deader! IE sometimes I only get a half dead weed that will come back. With the Ag Round-up just a dab will do ya.

I asked our local COOP what was the strongest license free herbiside I can buy was. He said Remedy. Funny that mix is Triclopyr at 61.6%!!!!
It isn't cheap but I think the per-acre mix is something like 8 oz.

Listening to our local Garden Line show this weekend he mentioned two products. One containing Triclopyr. This is the active ingredient in several products. For fence lines and such he suggested a product called Pramitol. Pramitol kills for a year because it gets into the ground. It's NOT good around trees, shrubs, etc. Nasty stuff. Since he mentioned it on a local radis show I guess these are items you can buy without a license. He mentioned it could spread as much as 5 feet in the soil.

Good Luck,
Rob

I went ahead and did the work to get a pesticide license--the non commercial variety. 2 4d Amine for 2 1/2 gallons is just under 40 bucks at the Co-OP. I figure the license paid for itself just with that trip.

Good thread so far.... Here's a good read I found concerning the addition of Ammonium sulfate to glyphosate and/or Round up.

This is also interesting. I have hard water at the city house so my roundup isn't working well there I guess. At the weekend place, soft water, slippery stuff in the shower!!

Where/how do you buy Ammonium sulfate (AS)?

The local co-op has it for around $10 per 50lb bag IIRC.

At the moment I'm pretty satisfied with the Lowe's version, although I mixed it fairly potent. If the Ag stuff will kill it deader, I'm all about that. I'm probably going to be taking out many of the trees on this fence line anyway, so if I get some collateral damage I'm not too concerned. I don't want to destroy the soil permanently, but every cell that splits in that fence row is one more cell that I have to remove later.

All true, but sometimes, you want permanent control. I don't think I ever want weeds growing between the bricks on my patio or driveway.

I've heard that adding a smidgen of glyphosate to 2-4-D or a smidgen of 2-4-D to glyphosate adds to their effectiveness. I've tried it, but don't notice a difference so far. Anyone try it, and how did it work?

Boy I hope this is true. Down here in South Texas, the farmers spray the tops of grain stalks with a duster before harvest so they can kill the stalk and low the moisture content in the grain for a higher profit. Maybe there's a low-fat version of Round-Up?

I got tired of cutting down Mulberry trees and having the suckers sprout back out of the stumps. One day after cutting down some trees again, I took some pure concentrated glyphosate and brushed it on the stump with a small paint brush. I coated just the area at the edge of the stump, right where the bark meets the wood.

Boy, that killed them! No more suckers and sprouts coming up from those stumps! I have done that ever since when I cut down Mulberrys or any tree that tends to resprout again, and it solves that problem. And it doesn't even kill the grass right beside the stump.
