Penetrates knotweed stems easily. The only change i would make is to move the outlet hole closer to the end.

Can I buy just the Foaming Agent though?

We dealing with knotweed and not only are tye products fantastic but the information provided is just as valuable. A+

I carry a small batch with me when I mow and spray the small weeds as I go so I don’t miss any. Works great for me!

Delivery said almost 2 weeks, it was here in maybe 4 days. Will keep yall posted as I haven’t applied quite yet. Although hi-yield products are pretty good.

This applicator is a game changer for cut stump herbicide application. The foaming aspect ensures that the herbicides sits exactly where applied with zero over spray or unintended application.

I wanted a product that I could apply directly to the foliage of if the plant I'm trying to eradicate. I have a fully established biodiverse native garden and I really didn't want to spray poison. But I've tried EVERYTHING else to eradicate the invasive goutweed, and it has begun to take over entire beds and kill my natives by stealing nutrients from the soil. This product was recommended in a group that exists to eliminate goutweed so I decided to try it. I reached out to the distributor and they gave me directions for the concentration for my specific needs. I had to do several applications over the summer, choosing hot sunny days where there was no chance of rain for at least a few hours. The product is pulled into the roots and poisons the plant from there. Since goutweed spreads by root, this is the most effective way to kill it.After the first application, it took a few weeks before I could see the plant dying off. I had so much of it to treat that I took the project in sections, so I could see what was working. The last treatment I applied was at the end of fall when the plants were pulling their sugars back into the roots to store energy for next spring. I'm hoping that I'll see a huge reduction in goutweed in the spring, which will make it easier to spot treat and control. I've recommended this product many times.

It takes the guessing out of the equation.

Works great for precision kills.

It takes about 2 weeks for this to do it's thing. Works well.

I'm a fairly experienced gardener, having been doing it most of my life. I had been fighting the bindweed in my garden for 7 years. I followed all the online suggestions--dig deep, don't leave any roots behind. For several years I would dig a 2-3 foot trench and systematically move my way across my garden to pull up every single piece of bindweed I could find. Every year it would come back with a vengeance (if your neighbors aren't doing the same, it's going to come back). Finally, this year, I realized no amount of backbreaking work was going to get this under control, so I did my research and saw the foam-based Killzall was very effective in bindweed control. I bought some, tested it in part of my garden away from my desirable plants, and was so happy with the results. It only killed the bindweed that I applied it to, and nothing else around it.I know herbicide gets a bad rap, but people really need to do their due diligence, research the products and learn how to use them, and educate themselves on proper usage. The foam application makes this almost idiot-proof, and glyphosate becomes inert after 24-48 hours. Climate change is affecting my local ecology rapidly, and it's becoming harder and harder to control invasive species. I'll take all the help I can get.

This stuff was so easy to mix up and use. I spent the whole winter outside cutting down buckthorn and honeysuckle and painting the stumps. I have not seen any resprouting this spring of anything I have used this stuff on. “A little dab’ll do ya”. One bottle will last quite a long while. I had a question about the product before purchasing and sent the seller an email and he got right back to me with helpful information. I highly recommend this product.

This is the second kit I’ve ordered..Works for Japanese Knotweed and Thistle.Targeted for less potential of over spray, like using just a few drops versus breaking out a big spray bottle.
