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.

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.

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

Amazing - Stop Scrolling and Buy This Pillow
Size: Queen (Pack of 1), Color: White
I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need. However, I researched pillows for longer than I care to admit, and decided on this one. I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day. I am a side sleeper, but flip flop all around through the night and it’s great in every position. Pros: Stays nice and cool, which is soothing regardless of the time of year. Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added. The fill is fully adjustable to your preference. I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect. It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later. There was no unpleasant scent sometimes associated with memory foam items. The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once. The affordability of this pillow compared to some of the others in this category can’t be overstated. Oh, and the packaging was very thoughtfully and securely done. If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing. I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

It's the perfect pillow!
Size: Queen (Pack of 1), Color: White
I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential. Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles. This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.
