Learning the Basics
How Do Roundup® Weed & Grass Killer Products Work?
We reveal the technology behind our products’ weed-killing success.
Before you use a product around your landscape, it’s important to know how it works. That’s why we’re providing you with this handy info about the science behind many Roundup® Weed & Grass Killer products. Let’s get learning.
RIGHT ON TARGET
The main active ingredient in Roundup® Weed and Grass Killer products is glyphosate. It works by targeting an enzyme that is essential to plant growth.
BANISH THE BAD
After you apply Roundup® Weed & Grass Killer products to the leaves, glyphosate works its way through the plant, all the way down to the root. And just like that, R.I.P. weed.
GUARD THE GOOD
Word of warning — glyphosate doesn’t discriminate between unwanted weeds and wanted plants, so make sure that your Roundup® Weed & Grass Killer products don’t touch anything green that you want to keep.
To help you guard the good, we developed our unique Sure Shot® Wand for precision weed sharpshooting.
- This handy wand gives a full two feet of reach for less bending over.
- The battery-powered motor gives you a continuous spray without ever having to pump.
- The clear dome shield allows you to apply Roundup® Ready-To-Use Weed & Grass Killer III point-blank.
How long does it take?
After applying, people and pets can return to the treated area once it’s dry. Once the plant is dry, not even rain can stop Roundup® Weed & Grass Killer products from doing their job.
Most Roundup® Weed & Grass Killer products deliver visible results in a few hours, though some take a little bit longer. For Roundup® Max Control 365, it takes 12 hours to see visible results, but the trade-off is year-long hassle-free weed control.
