Your first picture gives the dilution rates per litre, depending on which weeds you want to kill. It's a bit late though to be using it,usually recommends til sept.

It's nowhere near 1 in 10. When dealing with chemicals, ALWAYS take directions from the label rather than relying on other peoples guesses.

We can't say what the dilution rates are, even if we take the directions from the label, as we don't know what type of weeds you wish to use it for, or whether you're using a sprayer or watering can. As Snowdrops said, it's getting a bit late to use it anyway.
Did it really tell you to do THAT on the packet?

Your best bet is to wait until about April time, when the weeds start growing again.

(20ml in 1 litre is actually 1 in 50 -a fifth of the rate previously suggested).

You could try covering the grass & weeds over the winter to exclude light, at the least it will weaken them, then you can uncover in the spring or when you have time,weather conditions to deal with them,try to remove any seeds first. How big an area have you got to deal with?

This is what it says on the container

Watering can
add 50ml to 4 litres (1 gall) of water and stir. Apply evenly over 20 sq m (25 sq yards)
Sprayer
Add 50 ml to 1 litre (2 pints) of water and stir. Apply evenly over 20 sq m(25 sq yds)


That will kill tough established tough weeds such as dandelions, thistles, docks and grass.

A lower rate of 20 ml, litre can be used where only small soft weeds such as chickweed, fat hen and seedling grass are present. ( or cover twice the area with the  50 ml dilution)

A useful tool to apply Roundup (glyphosate) is a dribble bar. This fits on a watering can instead of the rose and helps to apply evenly. They are cheap from most garden centres.

A watering can/dribble bar is usually better than a sprayer, which is less easy to control and easily drifts on to other plants that you do not want to kill.

From my experience Roundup works even in cold conditions, although it is better when it is milder, obviously avoid frosty times.

The important rule is to apply it when there is likely to be at least 6 hours of dry weather after it is applied.

It may take some time before you see results. This usually is yellowing of the growing centres of the plants after about 2/3 weeks. Once the first symptoms show the chemical has reached the roots and the plant is effectively dead. At this point, and not before, you can cut the weeds off or dig them out.

I've found a glyphosate product called Pestshield Weedkiller, very cheap in poundshops. One spraying dispatched a bed of nettles on my allotment.

I was impressed.

Sorry to disagree,but on the mjludcans first picture the highest quantity of Roundup to add to 1 litre is 40ml for brambles etc

Which is why I said to take your directions from the label - and by that I mean the label that came with the product!

Quite correct DD.

Snowdrops has left the important bit of the instructions out.

40ml in a litre to cover how many square metres?
