Before you use a product around your landscapes, it’s important to know how it works. That’s why we’re providing you with this handy info about the science behind Roundup® Weed & Grass Killer products. Let’s get learning.
RIGHT ON TARGET
All Roundup® Weed & Grass Killer products contain the same active ingredient*, glyphosate, which targets an enzyme found in plants but not in people or pets. (Unless your pet is a plant. Sorry, Seor Habanero.)
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.
How long does it take?
After applying, people and pets can return to the treated area once it’s dry. For most Roundup® Weed & Grass Killer products, this usually takes 10–30 minutes, depending on the product, climate, and weather. For Roundup Precision Gel®, it usually takes about 2 hours. 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.
