This non-selective herbicide delivers what contractors need most: speed. Visible results in as fast as 3 hours and rainproof in 15 minutes — that’s performance you can schedule around in Montana’s unpredictable weather windows. 1 gallon covers approximately 300 sq. ft., making it efficient for targeted hardscape applications where grass and weeds have invaded patios, walkways, and driveways.
Skip this product if you’re treating established lawns. Not for use on established lawns — it’s a total vegetation killer that kills all green vegetation contacted. The formula targets everything from dandelions to crabgrass, entering through the leaves and working down to the roots.
Fast-Acting Performance in Real Conditions
The active ingredient blend does the heavy lifting: 0.12% Diquat Dibromide, 0.06% Fluazifop-p-butyl, 0.04% Dicamba. That 15-minute rainproof window matters when afternoon thunderstorms roll through the Flathead Valley or Mission Mountains. You’re not waiting hours hoping the product stays put.
Temperature matters with this formula. Apply in warm, sunny weather (> 60°F). In Montana’s shorter growing season, that limits your application window to late May through September in most valleys. Morning applications work best — you get the warmth without the afternoon wind that causes drift.

Application Strategy for Hardscapes
Ready-To-Use (RTU) liquid means no mixing math or concentrate measuring. The integrated trigger sprayer works adequately, though faulty trigger sprayer issues pop up in reviews. Keep a backup pump sprayer handy for larger jobs.
The product excels where it should: patios, walkways, driveways, around fences, around trees, flower beds, shrub borders, foundations. That’s your money-making territory — cleaning up hardscapes before seal coating, maintaining gravel driveways, and creating clean edges around structures.
Shake container well. Completely cover the leaves of target weeds. Avoid drift to desirable plants. That last point isn’t optional. This product doesn’t discriminate between weeds and your client’s prize petunias.
Post-Application Timing
The fast replant window sets this apart from longer-lasting herbicides. Replant after 1 day means you can spray Monday and plant Wednesday. Perfect for quick-turn landscape renovations where you’re clearing beds for new installations.
Do not mow for 7 days gives the product time to translocate fully through the plant system. Schedule accordingly — don’t promise a pristine lawn edge the day after treatment.
The Verdict
Worth it for contractors who need fast knockdown on small hardscape areas. The 3-hour visible results and 15-minute rainproof protection make it practical for Montana’s short season and unpredictable weather. At roughly 300 square feet per gallon, it’s not your solution for large-scale vegetation control.
The ready-to-use format trades convenience for coverage. You’re paying for pre-mixed product and immediate application. For bigger jobs or regular maintenance contracts, concentrates deliver better economics. But for spot treatments, quick cleanups, and jobs where mixing isn’t practical, this product delivers exactly what it promises: fast, visible results that stick through sudden weather changes.
Frequently Asked Questions
Q: Can I use this on my lawn to kill weeds? A: No. Not for use on established lawns. This is a non-selective herbicide that kills all green vegetation contacted. It will kill your grass along with the weeds. Use it only on hardscapes and areas where you want total vegetation control.
Q: How fast does it really work? A: Visible results in as fast as 3 hours for wilting and yellowing. Complete kill takes several days. The product becomes rainproof in 15 minutes, so you don’t lose effectiveness to unexpected showers.
Q: What’s the actual coverage per gallon? A: 1 gallon covers approximately 300 sq. ft. That’s for thorough coverage to completely wet the target vegetation. Light spot spraying might stretch further, but complete coverage ensures the kill.
Q: When can I replant after using this? A: Replant after 1 day. This quick turnaround makes it practical for bed renovation projects where you’re clearing old growth for new plantings.
Q: Does temperature affect how well it works? A: Yes. Apply in warm, sunny weather (> 60°F). Cold weather slows the product’s action significantly. In Montana, this limits effective use to late spring through early fall.
