Roundup Pro Max

Like the RoundUp Pro you've come to know and trust, Roundup Pro Max is a non-selective post-emergent that controls a broad spectrum of weeds with virtually no re-growth. With its more concentrated formula, one gallon of ProMax contains the glyphosate acid equivalent of 6 quarts of Roundup Pro. Roundup Pro Max has a unique surfactant system that's more concentrated and gets to the root faster, so you don't have to worry so much about the weather and rain washing the product away.


Active Ingredient: Glyphosate - 48.7%
Target pests: Annuals and Perennial weeds and Brush
For use in: Residential and Commercial areas, Parks and Recreational areas
Application: 2 oz. per gallon of water for most applications
5 - 9 oz. per gallon of water for Brush and Vines
* See label for complete application instructions
Formulation: Professional Product
Group 9 Herbicide
Manufactured By: Monsanto Company (UPC: 070183596096)


Product Information

Roundup QuikPRO is a postemergent, systemic herbicide with no residual soil activity. It is non-selective and gives broad-spectrum control of many annual weeds, perennial weeds, woody brush and trees. This product is formulated as a water-soluble granule containing surfactant and no additional surfactant is needed. Apply through most standard sprayers after dissolution and thorough mixing with water according to label instructions.

Time to Symptoms: 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. Extremely cool or cloudy weather following treatment may slow activity of this product and delay development of visual symptoms. Visible effects are a quick yellowing of the foliage which advances to complete browning of above-ground growth and deterioration of underground plant parts.

Mode of Action: One of the active ingredients in this product inhibits an enzyme found only in plants and microorganisms that is essential to formation of specific amino acids. A second active rapidly disrupts cell integrity of photosynthetically active tissues in the contacted foliage.

Cultural Considerations: Reduced control may result when application is made to annual or perennial weeds that have been mowed, grazed, or cut, and have not been allowed to regrow to the specified stage for treatment.

Rainfastness: Heavy rainfall soon after application may wash this product off of the foliage and a repeat application may be required for adequate weed control.

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

No Soil Activity: Weeds must be emerged at the time of application to be controlled by this product. Weeds germinating from seed after application will not be controlled. Plants growing from unattached underground rhizomes or root stocks of perennials that have not yet emerged at the time of application will not be affected by the herbicide and will continue to grow.

    5 of 5 stars  Leaking Container
    By Bruce in Naples, FL on 08/27/2015

    After receipt of my order and placing the box in the garage I returned a couple of days later only to find that the box was soaked with Round up. When I opened the container I found that almost one third of the contents were gone. After speaking with customer service via live chat they refunded me for the lost portion. Now that is what you call Great customer service. Just a little time from both parties and all is good. I look forward to ordering more from from your organization. Even with a leaky container I give your company a 5 star review, for caring about your customers.

    By Brian in San Antonio, TX on 04/15/2015
    Verified Purchase

    I like to use just slightly over the recommended strength to make sure it gets the job done, and this product definitely does just that. Weeds show the effects of being treated within just 2-3 days and they quickly degrade from there. The price per gallon of mixed solution cannot be beat.

    By Douglas in Wilmington Delaware on 08/29/2014
    Verified Purchase

    It killed all the weeds in a week. Then it killed all the grass. I followed the instructions to the tee. I thought a herbicide kills weeds only. I spent $1000+ reseeding after scraping all the dead grass down, many cubic yards of dirt and grass seed. Let alone many many hours. Be forewarned

    By Daniel in elgin texas on 04/07/2014
    Verified Purchase

    this stuff works better than regular roundup. it works slower which is actually better becuase you get a slower kill that goes all the way down to the roots. i spray somemesquite with it and some with regular roundup, the mesquite sprayed with promax died, the other burned off but then came back from the ground.not to mention how much cheaper this is than to buy the same amount in the smaller bottles at lowes. extremely cheaper!

QAre there any small animal safety precautions after spraying lawn with RoundUp?

ARoundUp Pro Max like most of our products is very safe to use around pets.  The general rule of thumb is to have your pets inside or in another part of the yard while you are applying the product.  Once the product has had adequate time to dry, usually 45 minutes to an hour, it is perfectly safe to have your pets back into the yard.

QIs it safe to use Roundup Promax on entire lawn? Would it kill the grass?

ARoundup Pro Max contains glyphosate which is a non-selective herbicide. Non-selective herbicides will kill just about any vegetation that they are sprayed on including grass. We do carry a full line of selective herbicides that can be safely sprayed on certain lawns and will only kill listed weeds. Try entering the name of the weed you are trying to eliminate in the search on our website. A selection of products should come up. You can click on each product and read the description and also the product label to see if the product will fit your needs. You can also contact your local cooperative extension office and request to speak to the master gardener on staff. The master gardener can make product recommendations for you based on the type of grass you have and the type of weeds you are trying to eliminate.

QWill Roundup Pro Max kill philodendron vines? Does it contain a surfactant?
Tried regular Roundup, and it had no effect. I need something stronger to clear out these tough to kill plants from my woods.

ARound Up Pro Max can be used to get rid of philodendron vines. You should cut back the vines and apply the product at the strongest usage rate to the freshly cut vines for best results. Round Up Pro Max does contain a surfactant so an additional surfactant is not needed.

QShelf life and temperature? How to use on tree stump after cut 1 year ago?
What is the shelf life and how to store? How to use after on tree stump from preventing newly Sprouts from a peach tree?

ARoundup Pro Max works best on actively growing vegetation. According to the product label "Apply a 50- to 100-percent solution of this product to the freshly cut surface immediately after cutting. Delays in application may result in reduced performance." Because of these label recommendations Roundup Pro Max may not be suitable for your needs. We do carry Fertilome Brush Killer and Stump Killer which is labeled to get rid of stumps and also to stop stumps from sprouting. This product will last for about 3 years from the date of purchase and should be stored out of extreme temperatures and kept away from direct sunlight.

QWill RoundUp Pro Max kill crabgrass and potato vines?
I have an undeveloped lot next to my home and the vines are growing rampant into my trees and bushes.

A

Yes, Roundup Pro Max will kill crabgrass and almost any weed, grass or vine it gets sprayed directly on. It will not prevent new growth of those items, rather it†will kill whatever you directly treat. Some vines, if well-established, may require a higher concentration or multiple applications to get full control.

QWill Roundup Promax kill the invasive chameleon plant?
manually removing the plants and as many of the roots and rhizomes as possible and disposing of them by incinerating them

A

Roundup Promax is not labeled to treat chameleon plant so we cannot confirm if it will work on it.  It appears this type of weed is best controled by manually removing the plants and as many of the roots and rhizomes as possible and disposing of them by incinerating them.  This will need to be done multiple times to get complete control.  It might also be helpful to contact your local cooperative extension office and speak with the master gardener on staff to see if they are away of methods that others have used to control this plant in your area.

QWe live in the woods & want to kill the brush/weeds but NOT the trees? Would this work for our application?

ARoundup works great as a spot treatment. Crossbow is known to be a great product to kill brush and other unwanted woody plants. You should not spray if it is windy and be careful that over spray does not get on the desirable trees.

QHow much Roundup Pro Max will i need to kill a 3.5 acre field filled with grasses and weeds?
Should i spray now or in spring before soybean planting?

AYou will need two 1.67 gallon jugs of Roundup Pro Max to kill all vegetation on 3.5 acres. Simply mix 2 oz of RoundUp Pro Max per gallon of water for most applications. Roundup Pro Max does not provide long term control so we would recommend treating two weeks prior to planting.
