OMRI Listed

Finalsan® is a patented fast-acting weed, grass, algae, and moss killers that represent a new class of products for organic weed control that do not contain glyphosate or other toxic chemicals!  Utilizing concentrated and potent and non-staining fatty acids (soaps), Finalsan is a non-selective herbicides and the best new top-of-the-line technology for fast-acting and through killing or suppression of many common annual, biennial, and perennial weeds, algae and mosses. A great organic product for use when conventional herbicides are banned or not desired!

We are now excited to offer Finalsan in smaller, more home friendly sizes under the Captain Jack's Deadweed Brew label! Now you can treat your own lawn with professional-grade results!

Why is Finalsan the Best Natural Weed Killer?

Herbicidal soaps work by penetrating the waxy cuticle of plants, causing the plant to dehydrate and die. The active ingredients accumulate in plants and cause intracellular damage, leading to cell death. Activity is non-selective and will kill plants the soap comes into contact with, but will not translocate to underground portions of the plant or harm the bark of mature, woody plants.  Can be safely sprayed around the base of trees, shrubs, hops, grapes without worry.  

Use on weeds within vegetable and flower gardens, landscaped areas, lawns (for spot treatment only), in the vicinity of small fruits and fruit trees, around and on buildings, sidewalks, fences, bark mulch, driveways, patios and gravel.  Use on moss and algae, around and on buildings, roofs, decks, sidewalks, fences, bark mulch, driveways, patios and gravel. Finalsan can even be used in cool weather. Areas can be planted five days after treatment.

Finalsan reduces tree toxicity risks and leaves no harmful residue in the soil. It won’t stain bricks, concrete or asphalt and people and pets can re-enter areas once spray dries.

            Definitely recommend. My new rescue has chewed though I can’t even tell you how many “indestructible” toys in under 10 minutes. Not this! We’ve had it a few days and she loves it. Hasn’t chewed through it at all and it literally keeps her busy for an hour at the minimum. Would buy again. Great quality for the price and made to last. Perfect for aggressive chewers.

            Great for Slowing Down Snack Time
            Size: Large (Pack of 1), Product Packaging: Standard Packaging
            My dog, an English Lab, is a voracious chewer, and destroys most toys in a matter of seconds. He also swallows most snacks without even chewing, and finishes meals in record time. It takes him about 20 minutes to get everything out of the Kong, and since I hide it somewhere on our property, he also takes several minutes to find it. He seems to really love the challenge, and it’s nice to have him take more time with a snack. I tried the Kong Easy Treat to seal the toy, but I find peanut butter works just as well (especially when frozen after being filled and sealed), and it’s cheaper and easier to use.

            This is the only toy I've had which my dog hasn't destroyed in minutes. I have had a few others that will at least last a few months, but Kong extreme has held up over the years. I like the fact that I can stuff it with treats, bits of other "indestructible" toys and seal it up with peanut butter, then pop it in the freezer to give her an extra 15 minute challenge. I have a couple so I can clean one while she's busy with the other. This size seems to be the best for a ~90lb. dog, the large end being roughly the same size as a tennis ball, which she loves as well.

            Great product but choose a size or two up
            Size: Large (Pack of 1), Product Packaging: Standard Packaging
            Nice quality toy for long lasting and engaging play! One star docked for the sizing—I don't usually expect to need an xl anything for my 45lb border collie but he cant even fit his canine teeth into the large size to ease the jerky reward out in "hard" position but "easy" position he doesn't even tough the toy just grabs the jerky. Got an XL and it has been great for the jerky both easy and hard positioning. The larges I keep around for liquidy and frozen treats to keep the mess contained and they work very well for that.
