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. ## 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.gr/products/41449053-alligare-imazapyr-herbicide-4-sl-for-broad-spectrum-control-185](https://www.desertcart.gr/products/41449053-alligare-imazapyr-herbicide-4-sl-for-broad-spectrum-control-185) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-10*
