Broad-leaved and grass weeds including:

Finalsan® is a contact herbicide for post-emergent application and 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. It can be applied up to eight times per year at a rate of 17ml/m2.


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
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.


Instructions For Use

Where to use

For use on

  • Amenity grassland - Areas of semi-natural or planted grassland subject to minimal or non-intensive management.

  • Managed amenity turf - Areas of frequently mown intensively managed turf, including fields used for turf production.
  • Natural surfaces not intended to bear vegetation - Areas of soil or natural outcroppings of rock that are not intended to bear vegetation.

  3. Top-up the spray tank with water to the required level
  4. Use immediately being sure to thoroughly cover target weeds, moss or 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.

I love it for my workspace! Hot tea all day
Color: Wood Grain
I love this item. The size is perfect, as I prefer something less bulky for my work desktop. It isn't as fancy as others that has the digital display screen, which is fine by me, because I don't necessarily need that. The knob and different colors that indicate the temperature range works fine. The temperature on this thing works fantastically well for me. Using it on the lowest setting keeps my drink nice and hot in a cold office. I use a heatproof glass teapot with this and its a good fit. It keeps my tea hot throughout the day, so I am able to pour smaller amounts of drink and take my time sipping it throughout the day without worrying that it will get cold. At point I almost forgot that it has an automatic shut-off safety feature when I noticed it was off. So that is a good feature to have. I highly recommend this.

Requires a very specific mug to be useful.
Color: Black
The hotplate itself gets hot enough on its highest setting where it would burn your finger if you left it one there for more then a couple seconds. However when it come to what mug you can use to transfer that heat to your drink, this WILL NOT work with just any old ceramic, metal or glass mugs. You absolutely need to have a perfectly flat bottom on it. If the center of the bottom of the mug does not make direct contact with the very center of the warmer, it will not transfer heat. So straight way plan of spending another $15 to $20. Amazon has some available with good reviews all be it not a very big selection. I'm giving this 4 stars because the description needs to be very clear about this and its not.

Great mug warmer with temp control
Color: Black
I replaced a cheap mug warmer with a couple of these for the house, and for almost the same price this is a lot more functional. I really like the temperature control and silicone surface protector. In combination with the carafe below, this has changed my life - no more microwaving coffee all morning. https://www.amazon.com/GiNT-Stainless-Thermal-Thermos-Retention/dp/B07MW5N7MS

Super Satisfied Customer Here!
Color: Gold, Color: Gold
I purchased the gold/black mug warmer. I always spend a good about of money for great coffee products and I take my time to perfect my coffee for my mornings at work. However, I get pulled into urgent meetings and just something urgent and I always leave more than half of my coffee behind. When I come back it’s cold and that’s very disappointing considering the money and time I spent to make it bc I then have to toss it. I don’t believe in microwaves and I refuse to use one. When I found this, I was super excited! It looks perfect at my desk and it works perfect! I would have liked it to be more on the brass gold like my pen holder, but it’s just as pretty! As you can see, my mug had a layer on the bottom and that made me think it may not work well, but it did the job. My coffee was super warm and it got even hotter as I left it there tearing it. I turned it one before making my coffee, so I’m not sure exactly how long it took to warm up but for me, by the time I got back, it was the peg temperature. I highly recommend this to anyone who has the same struggles. No more cold coffees! Thank you!!!

This jar is exactly what I was looking for. The 64oz size is great for making multiple servings and the wide mouth makes it easy to fill and clean. The glass feels sturdy, the lid is truly leakproof, and it’s perfect for cold brew. Simple, reliable, and well-made. Highly recommend!
