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. 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. For this product to be effective, make sure that weeds have emerged at the time of application. This product comes in a 1.67-gallon jug with a 6 ½ fluid oz measuring cup.
Roundup Pro Max is a post-emergent, 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. Roundup Pro Max is formulated as a water-soluble 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:
Roundup Pro Max 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:
Tthe active ingredient in Pro Max inhibits an enzyme found only in plants and microorganisms that is essential to formation of specific amino acids.
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.
Heavy rainfall soon after application may wash this product off of the foliage and a repeat application may be required for adequate weed control.
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 Roundup Pro Max. 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.
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
Is it safe to use Roundup Promax on entire lawn? Would it kill the grass?
Roundup 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.
Are there any small animal safety precautions after spraying lawn with RoundUp?
RoundUp 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.
Will 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.
Round 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.
