How do i mix roundup??

[EGo_SmAsH]

Hi there, I'm planning to spray a section of my lawn to re-seed and I'd like to kill it all 1st with roundup. I have a jug of agricultural/industrial "roundup ultra 2" concentrate and my sprayer holds 200 liters. Not sure now much roundup to add assuming i mix a full 200 liters. Thanks for any help.

I mix my concentrated herbicide 4oz to a gallon of water..

Don't know much, about them liter things.

Down here in Alabama, we barely can do, pints,quarts and gallons:laughing::laughing:

Like loghouse511, I don't know anything about liters, but I mix 2 1/2 oz of Roundup Ultra to a gallon and it works for me. Using more won't hurt, but that stuff is expensive and we go through a lot.

The instructions are on the label. Read it and follow them.

These are really rough numbers, but 200 liters is about 53 gallons. That would be about 133 oz of round up or 1 gallon( 3.78 liters)

I think.

TripleR hit it, using too much (within reason) won't hurt, so I'd just use it all and keep going until the sprayer is empty.

Also, I always add some dish soap. This helps to spread the roundup more evenly on the leaves.:thumbsup:

Good to know, I usually add crop oil.

I like to add some dye to the mix. Then I know if I've missed something.

Actually, using too much can hurt. Although there is some leeway before you hit this point. The thing homeowners do too often with Roundup and similar herbicides is apply too high a concentration in hopes that it will kill the plant better or faster. The problem comes when the top of the plant is killed too soon and the plant vascular system does not carry the chemical to the root system. The tops die, but the plant recovers.

The trick is to mix the correct ratio and give it time to work. Too fast and you get to do it all over again.
