This product is a post-emergence, systemic herbicide with no soil residual activity. It gives broad-spectrum control of many annual weeds, perennial weeds, woody brush and trees. It is formulated as a water-soluble liquid containing surfactant and no additional surfactant is needed or recommended. 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 MIN.

The active ingredient in Roundup PROMAX, glyphosate, is absorbed into the green vegetation and is translocated throughout the plant, including the roots. Glyphosate works by inhibiting production of an enzyme that is essential to formation of essential amino acids in plants. Obvious signs of treatment may not be visible for one to four days in annual weeds and for up to seven days or more in perennials. Visible effects include gradual wilting or yellowing followed by complete browning and deterioration of plant tissue, and ultimate decomposition of the underground roots and rhizomes. Since Roundup PROMAX works only on plants that have emerged through the soil, it will not affect seeds in the soil that have not yet sprouted. When desirable vegetation is in close proximity to weeds, care must be exercised to keep Roundup PROMAX off of green plant tissues.
