It is a total vegetation herbicide. You might google the Arsenal label and look at species controlled and rates to use. My guess would be that it will kill Palmettos, not sure of rate. Usually conifers are not affected by Imazapyr. Thus the large usage in pine production. If you have palmettos I would assume that you are in the Florida area. You might google palmetto control in pine production and you should get an idea of what herbicides to use for control. **Q: i spray with this product, several applications, does not seem to be working on roseau, how long does it take to start turning brown** A: It didn’t work for me even full strength on several types of plants **Q: Will this kill Cogon Grass** A: I do not know, but it will kill centipede, unlike what some other people have stated. It seems to kill any grass or weed it comes in contact with. **Q: I've read that a 1% solution of imazapyr can kill bamboo. How much of your product would I use for a 1 gallon solution? Thanks.** A: 1 1/3 oz per 1 gallon for 1% solution. Also include a surfactant. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by A***R on July 23, 2026* Very effective on invasive alligator weed, in or out of the water. ### ⭐⭐⭐⭐⭐ It works *by A***R on April 17, 2026* Kills bamboo but it does take a while so don’t expect instant results of your buying this specifically for bamboo. It also kills most brush and small trees. It will kill your grass dead so be careful when applying it. Also wear goggles and exam gloves. ### ⭐⭐⭐⭐⭐ The product and delivery were great. Now I need to see if it kills Tree Of Heaven. *by M***B on August 30, 2025* The shipping on this was fast and very safely packaged to avoid rupture and/or leakage. I purchased it after some research to find something that could kill Ailanthus, aka Tree Of Heaven. I have an Ailanthus that established itself among some blueberries in my backyard garden, and despite chopping it down and applying Roundup to the stump, it's regrown suckers every year for the last five years. I carefully read my state's guidelines and restrictions, as well as the label instructions and methods of application, and decided on an injection method. I used a hand-drill and 18-gauge syringes to inject the two current suckers (actually small trees at this point) during the late summer, early fall period recommended. After three days, there seems to be a pronounced wilt to the leaves, and am expecting that they will yellow within the week. Following the instructions, I will leave the suckers intact for a month, then cut and remove them. The benefit of this weed-killer is that it affects the roots with apparently 99% effectiveness, without affecting surrounding plants overmuch, so I'll keep on observing and report back later, but it seems to be working. ## Frequently Bought Together - Alligare Imazapyr 4 SL - 32oz - Triclopyr 3 (2.5 Gallon)-Compare to Garlon 3A - Liquid Harvest Lazer Blue Concentrated Spray Pattern Indicator 8 Ounces Perfect Weed Dye, Herbicide Fertilizer Marking Turf Mark and Marker --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/41449053-alligare-imazapyr-herbicide-4-sl-for-broad-spectrum-control-185](https://www.desertcart.co.za/products/41449053-alligare-imazapyr-herbicide-4-sl-for-broad-spectrum-control-185) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-07*
