Finalsan® is a contact herbicide for post-emergent application. It controls a broad spectrum of annual and perennial broad-leaved weeds and grasses, mosses and algae on amenity grassland, amenity vegetation, managed amenity turf, and natural surfaces not intended to bear vegetation. It can be applied up to eight times per year at a rate of 17 ml/m2.
|Active Substances||Fatty acids: pelargonic acid|
|Areas of Use||Amenity grassland, amenity vegetation, managed amenity turf, natural surfaces not intended to bear vegetation and various fruit and vegetable crops|
|Mode of Action Group||Unknown mode of action|
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 10 L bottle is sufficient to treat 588 m2.
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.

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.
