Finalsan
Finalsan® contains the active substance pelargonic acid, a naturally occurring fatty acid. It is a fast acting contact herbicide which delivers rapid knockdown of young and actively growing weeds as well as mosses and algae. Treated plants will begin to collapse within hours of application with complete burndown of top growth often achieved within 24 hours.
Finalsan® is a contact herbicide with no residual activity. This makes it particularly useful for use as a directed spray for controlling annual weeds in places where systemic herbicides can cause unwanted damage.
For control of mosses it is important to achieve thorough coverage and to repeat applications if required.
This 10L bottle is sufficient to treat 588m2.
Target Species
Finalsan® gives post-emergence control of a wide range of broad-leaved and grass weeds including the following:
| Grasses | Annual Herbs | Perennial Herbs | Woody Plants |
|---|---|---|---|
| Annual meadow-grass (Poa annua) |
Red dead nettle (Lamium spp) Chickweed (Stellaria media) Knotgrasses (Polygonum spp) |
Dandelion (Taraxacum officinale) Greater plantain (Plantago major) Creeping thistle (Cirsium arvense) |
Established broadleaved perennial herbs may require repeat applications as Finalsan® does not work systemically within the plant and therefore may not prevent re-growth. Finalsan® also controls mosses and algae.

Additional Information
- Do not direct spray or allow spray drift onto cultivated plants.
- Use a spray shield to avoid contact with leaves or fruits of cultivated crops.
- Do not apply until weeds have established and ground cover has reached approximately 25%.
- The effect can be lessened at temperatures below 15°C.
- Rainfall within less than 12 hours after treatment may impair the effect of the product.
- Avoid applying within 5m of the field boundary to reduce effects on non-target insects or other arthropods.
- Repeated application may be required as Finalsan® does not have a long-term effect.
- Can be used under shrubs and trees because Finalsan® does not harm the woody parts of plants.
- Some transient scorch or bleaching and reduction in the growth of treated areas of turf is likely following applications to grass or turf.
- Do not apply to grass suffering from drought or during freezing conditions.
- Do not cut grass for one day after treatment.
Active Substances
Pelargonic acid
Bio-Chemical Mode of Action: Pelargonic acid belongs to the group of herbicides with an unknown mode of action. It is thought that pelargonic acid penetrates the waxy leaf cuticle destroying the cell membranes. This results in rapid desiccation of the cell contents.
Mobility: Pelargonic acid is a contact herbicide which means that only plant tissues that come into contact with the herbicide will be affected.
Application timing: Pelargonic acid is best applied when temperatures are greater than 15°C and weed cover is at least 25%.
Resistance: The risk of resistance development is considered to be low.
