## Description

Product description

Review: It works - 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.
Review: Works great - I have been using Imazapyr to keep weed out of my gravel drive way and along my fence post for years. I apply it in Feb/March while it is still cool and don't have to keep spraying. Also like that it is not harmful to amphibians as we live near water and have a pond. I can't find this in the local box store, so its a bonus that it is delivered to me!

## Questions & Answers

**Q: Has anyone tried to kill Palmettos with this?**
A: Hi W D,  I used to work for BASF who sells Arsenal.  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.

### ⭐⭐⭐⭐⭐ Serious long-term vegetation control—use with care
*by A***N on June 4, 2025*

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.
