  • Fastest working Roundup® brand concentrate product.

  • Concentrated and dilutes to cover big jobs.

How to Use

  • Use of a Roundup® branded tank sprayer is recommended to spray the weeds you want to kill until thoroughly wet. If a desirable plant is accidentally sprayed, rinse off immediately with water. People and pets may enter treated areas after spray has dried.

When to Apply

  • Apply when weeds are actively growing. For best results, apply during warm, sunny weather (above 60° F). Spray when air is calm to prevent drift to desirable plants. Weeds usually begin to wilt within 12 hours and complete kill in one to two weeks.

Where to Use

  • Use in and around fences, trees, driveways, and flower beds. May also be used for lawn renovation and vegetable garden bed preparation. All ornamental flowers, trees and shrubs may be planted one day after application. Lawn grasses, vegetables, herbs and fruits may be planted three days after application.

Coverage Area

  • One quart makes up to 10 gallons of spray at the 3 oz./gal. rate.

Kids and Pets

  • People and pets many enter treated area after product has dried. Glyphosate targets an enzyme found in plants but not people or pets.

Our Environment

  • To protect the environment, do not allow pesticide to enter or run off into storm drains, drainage ditches, gutters or surface waters. Applying this product when rain is not predicted for the next 24 hours will help to ensure that rain does not wash pesticide off the treatment area.
