This is the info I have. You will have to convert the amount.

Hydrogen peroxide

House plants: add 1 ounce of 3% hydrogen peroxide (or 16
drops of 35% solution) to every quart of water you give your
plants.

Insecticide. Spray your plants with 8 ounces of 3% peroxide
mixed with 8 ounces of white sugar and one gallon of water.)

Sprouting seeds: Add 1 oz. to a pint of water and soak the
seeds overnight. Add the same amount of hydrogen peroxide
each time yourinse the seeds.

House and garden plants: Put 1 oz. in 1 quart of water. Water or
mist plants with this solution.

Insecticide spray: Mix 8 ozs. white sugar, 4-8 ozs. hydrogen
peroxide in 1 gallon of water.

Hydrogen Peroxide
This is commonly available in a 3% solution. It may be used in
full strength for about 20 minute to disinfect seed and alter
the seed coat. The peroxide may then be diluted in half with
water and the seed soaked for up to 24 hours.
