Alligare Imazapyr 4 SL - 32oz

If you’re looking for permanent solutions, this is it. Imazapyr doesn’t mess around—it kills everything down to the root and keeps it dead for the long haul. I used it on invasive blackberry and overgrown fence lines, and weeks later, not a single sprout has returned. Just be careful: it has soil activity, so don’t use near trees, gardens, or anything you want to keep alive.✅ Extremely effective for tough, woody, or invasive plants✅ Results visible in 1–2 weeks, lasting months✅ Great for fence lines, vacant lots, and gravel pads⛔ Not selective—kills everything, including grass⛔ Can linger in soil—be mindful near desirable vegetation🧪 Pro Tip: Mix at about 1–2 oz per gallon with a surfactant for best results. Use a marker dye if you’re covering large areas.If you’re managing land or need an aggressive herbicide, this is pro-grade and powerful. Just respect the label—this stuff is no joke.

Works great with roundup for killing weeds.

Excellent product, exactly as described, delivered next day at a very fair price. What’s not to like. I will do it again.

Product was received with a completely different bottle design, which is greatly improved and provides measuring and other options when using it, but an immediate and clear, simplified table of mixing ratios should've been upfront in the long-winded attached booklet. Will update if this products performs for my intended vegetative invasion (if not, it didn't).

I use this to mix with my regular weed killer - I usually mix a little on the heavy side - but by doing so it creates a true weed and “woody brush” killer - I usually spray twice per season along fence line and steep banks

This herbicide is completely useless! I spent over two hours spraying it in my backyard, but weeks later, the weeds are growing even thicker and healthier than before. It had zero effect. I want a refund.

This is undoubtedly effective. We have a large amount of rock covered areas in our landscaping. Keeping the weeds away is always an expensive challenge. We've used a combination of preen and an all ground clearer sold at Home Depot. Since this product has the longer term active ingredient found in the hardware store and much more concentrated, I gave it a try.I used this product to mix the lowest concentration on the label and then sprayed all the areas as I normally have in the past. It did a fantastic job of killing and keeping away weeds for 3+ months. The only problem is it killed one of our smaller bushes. Also, in one area there is a grassy area at a lower level than the rocks. All the grass within 4 feet of the rocks was killed. I've never had that problem before. I can't really blame the product for this. The next time around, I'm going to mix the concentration down lower so that it is about the same as that recommended by the hardware store product. That should give me a good balance of killing weeds, not killing grass or bushes and cost savings. This product is concentrated enough that I expect it will last me 4-5 years.

Good herbicide for treating stumps and sweetgum trees.
