Ammoniated soap of fatty acids 220g/ℓ

Reg. no. L6959  Act 36 of 1947

Directions and Application

Best results are obtained with young, actively growing weeds, less than 12cm in height. Will also control algae and moss on driveways and patios. Effect on weeds, moss and algae will be visible from within a few hours to 2 days. Repeat application if necessary.

1 part Finalsan to 5 parts water

Application instructions
Spray target weeds thoroughly, using a coarse nozzle setting to reduce drift onto non-target plants. For spot treatment of indivual weeds, apply the mixed solution to the centre of the plant to the point of run-off. Repeat treatment every 2-3 weeks to control new weeds growing from seed, and re-growth from bi-annual and perennial weeds. Shake well before use.


All Crops


Finalsan has been found to be compatible with most commonly used herbicides. Physical compatibility should first be checked by using the current proportion of Finalsan and other products in a small test jar. Growers should then test tank mix combinations for phytotoxicity on a sample of plants or crops prior to use. Do not apply in temperatures above 30ºC.
