How many litres of water to dilute 1 litre of roundup

what does the size of the round up container say ?
it depends on what you want to get rid of. Weedy plants, vines , broad leaf plants need more round up guess 80 ml per litre.
Grass 20 - 35 ml per litre
However it really depends on the round up as some round up is a higher concentration and then you need less roundup to water

Depends on what kind of weeds, but for most broad leaf weeds 20mls of roundup per litre of water is normally plenty. i.e. 200mls for 10 lits.
If you have couch that you are trying to kill you should triple the amount and possibly spray it twice.

For general use I use 3 ounces of herbicide per gallon of water. For best results spray on a calm warm morning.

Using the standard 10ml of Roundup per litre of water you can kill the grass without harming your vegetables. I would spray only on a nice calm day and use a piece of cardboard to block any over spray from reaching your veggies. Roundup works through absorption by leaves so transfer by groundwater is not a concern. Also remember more is not better with Roundup, too much just kills the leaves before they can absorb the toxin and kill the root.

usauly about 15ml / ltr . hope that helps

for roundup weed & grass killer concentrate plus you would use 3 oz per gallon or 29.57 cm^3 per litre

The label on the back of the container has 5 pages of information. Pull the right hand side of the label and it opens out. One page of it says 125ml of rosate to 4.88 litres of water for a 5 litre sprayer. I hope this is helpful. J.D
