PH random wisdom required re old lawn products

[DonkeyApple]

Working my way through a collection of various garden products that had been doubled up over the years at different places and times.

Anyway, I assumed that Google would tell me immediately how many ml per l in a sprayer for this but that doesn't appear to be the case:





The age of the product may be as much as 20 years.

Should anyone know If be very grateful before taking random guesses.

You could google the correct g/l dose rate for MCPA, mecoprop and dicamba on a lawn, then work out how much of your product to use per litre as you have the percentage of each ai. Remember it's the concentration of the diluted product that matters...!

You could find a bottle of similar stuff in your local shop with similar to '100m^2' coverage and adapt?

Some stuff with similar ingredients might have info online?

Not specific but

What is the dilution rate for weed and feed?
Dilute 300ml from the bottle into 9 litres of water (for watering can) or 150ml from the bottle into 4.5 litres of water (for a pressure sprayer). 3. Apply over 20 square metres using a watering can and sprinkle bar or apply over 10 square metres using a pressure sprayer.

100sqm would be 1.5 litre bottle ..but not far out ... and if it's that old it's probably lost a bit of omph
