Product Information

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. 

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 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.
