Overview

Roundup Concentrate Poison Ivy Plus Tough Brush Killer is designed to tackle the most stubborn weeds with a dual-ingredient formula that penetrates waxy leaves and woody brush. It targets poison ivy, poison oak, poison sumac, invasive vines, and stubborn shrubs such as kudzu and wild blackberry, helping you reclaim space in your yard.

How it works

The two active ingredients work together to kill weeds down to the root, including ivy and tough brush. The product is formulated to move through the plant’s surface and reach the root system, which can reduce the chance of quick re-sprouts when applied to actively growing plants.

What you get and how to use

  • Mix 6 fluid ounces of concentrate with 1 gallon of water for spray applications.
  • Undiluted concentrate can be used for stump treatment, following label directions.

Application tips

  • Apply during warm, sunny weather when weeds are actively growing, ideally above 60 degrees Fahrenheit.
  • Spray until the target area is thoroughly wet, and avoid drift onto desirable plants by applying in calm conditions.
  • Rain or watering within 30 minutes of application will not wash away effectiveness.

Expected results and follow-up

Weeds typically begin to wilt within two to four days and may be completely killed within one to two weeks. If some weeds remain after four weeks, repeat the treatment as directed on the label.

Usage notes

Do not use near edible crops or for lawn renovation or flower bed and vegetable garden preparation. This product is available as Ready-To-Use and Concentrate to fit different project sizes. Always follow the label for mixing, timing, and safety instructions.
