Roundup Promax has a smaller molecule size and higher concentration of glyphosate (48.7%) than Roundup Pro. Roundup Pro and it's generic equivalents that contain glyphosate are well known as systemic postemergence herbicides.
For those familar with Roundup Pro or it's generic Eraser (41% glyphosate), know they control a broad spectrum of weeds (annuals,perennials,woody brush and trees) with very little re-growth. However, Roundup Pro Max gets to the root faster, so if it rains in an hour you don't have to worry. Round up Promax is rainfast in just 30 minutes. See Monsanto's Rainfast Warranty.
Visible signs of treatment may not be visible for 1-4 days in annual weeds, and up to 7 or more days for perennials. Signs include a gradual wilting or yellowing followed by complete browning and deterioration of plant tissue, and ultimate decomposition of the underground roots
Roundup Pro Max only works for plants that have emerged from the soil, it will not effect the seeds.
