Roundup ProMax

Free Shipping on All Orders

Roundup Pro MAX is a herbicide that penetrates the leaves and moves to the roots of weeds faster so that in can provide weed control, with virtually no regrowth. When you spray Roundup on a weed, it is absorbed by the plant, where it then prevents the plant from making its own food and gathering nutrients to sustain itself. Roundup is then transported throughout the weed to kill the entire weed, roots and all.

Target Pests

Annuals and Perennial weeds and Brush

For Use In

Roundup PROMAX® herbicide is used to control weeds and brush in professional vegetation management situations such as turf management landscaping roadsides and utility rights of way.


Use 2 oz. of concentrate per gallon of water for most applications. Brush and Vines will require 5-9 oz. of solution per gallon of water. Please see the label for complete use instructions.

Coverage Area

Uniform and complete spray coverage will provide best results. Do not spray weed foliage to the point of runoff.

Time to Kill

This product moves through the plant from the point of foliage contact and into the root system. Visible effects on most annual weeds occur within 1 day, and on most perennial weeds in 2 days. -

RoundUp Pro Max Herbicide Performance

Roundup ProMax boasts of faster visual symptoms, improved performance and consistent weed control for those pesky invasive plant species you find on your lawn.

Roundup PROMAX is formulated as a potassium (K+) salt. The smaller K+ – salt molecule allows a 33% higher concentration of glyphosate in every gallon.

• Roundup PROMAX contains 4.5 lbs. acid equivalent (a.e.) per gallon vs. only 3.0 lbs a.e. per gallon in older 41% IPA Salt Formulations.

• The new 1.67 gallon jug of Roundup PROMAX makes up to 142 gallons of spray solution at
the annual weed use rate of 1.5 oz, per gallon or 106 gallons at the 2.0 oz per gallon rate
recommended for perennial weeds, brush and vines.

• Additional surfactant is not required or recommended.


RoundUp Promax 30 Minute Rainfast Warranty

• The unique surfactant system used in Roundup PROMAX allows faster leaf penetration and gets the
weed killing power you need into the plant in as little as 30 minutes. That’s half the time of the old
Roundup PRO. So Monsanto offers a 30 minute rainfast warranty to back you up. Performance the
imitators are still trying to match.


Faster leaf penetration also means the maximum amount of weed killing power gets down into the
roots in as little as 24 hrs. You’ll see faster visual symptoms and the consistent weed control you’ve
come to know and trust with Roundup. Choose Roundup PROMAX and worry less about the weather,
poor results and costly callbacks.



Red Spray Pattern Indicator (Brandt Mark-It) - Keep track of your spraying and avoid overspraying with this spray.

Will this kill weed only? No damage to st. Augustine grass?
Lala on Mar 6, 2017
BEST ANSWER: The Roundup ProMax is a non-selective post-emergent that is used to control a broad selection of weeds. With it being a non-selective herbicide it will cause damage to your St. Augustine grass. You can spot treat the weeds that you are wanting to eliminate and allow the St. Augustine to take over that patch on the lawn.
What is the mixing ratio , how many ounces per gallon?
A shopper on Jul 13, 2018

Will this product kill Staghorn Sumac plant (bush) ?
Patrick M on Jun 18, 2018
BEST ANSWER: One of the best is triclopyr (Garlon).There are two chemical forms: Garlon 3A is the water-soluble form and is recommended for foliar spraying (used at 3% concentration) whereas Garlon 4 Ultra is the oil-soluble form and is recommended for cut stem and basal bark treatments (used at 20% in bark oil). (There are “generic” versions of triclopyr that are less expensive and but are equally effective.)

Will it harm horses or pets?
A shopper on Mar 29, 2018
BEST ANSWER: The label says to let the spray dry for an hour prior to allowing pets on it. Since horses are herbivores I probably wouldn't allow a horse on it until the sprayed area shows visible death.
Will this product damage trees?
A shopper on Jun 21, 2018
BEST ANSWER: No, Roundup Pro Max will not damage trees as long as you do not spray it directly on the leaves.

Will this product kill bamboo ?
Ra D on Apr 2, 2018
BEST ANSWER: Yes, Roundup would definitely kill Bamboo but we recommend apply a fertilizer at the same time, kind of tricks the bamboo. Allow it to completely draw the mixture in and do not cut the bamboo down.

It will take some time, but eventually the plant will fall over and you can simply pull it out.

Response from Solutions Stores
This is pretty typical of a herbicide, and it does depend on what you are applying it to also. If you want a quick burn the Quick Pro is a good option because of Diquat creates a distinctive burn.

Very Effective.
You have to be careful to not get into the mist of this product when spraying but it is very effective and will kill other things if the wind takes it.

I haven't used the product yet...however, if it is every bit as good as the regular Round up, this is a phenomenal price break! The service was good from epest and it was delivered in a very timely fashion.
