RoundUp Pro Max contains glyphosate, which is absorbed systemically into the treated plants only. It does not move through the soil to other plants, and it is not absorbed from the roots into neighboring plants. Since this product is not labeled expressly for us around edible plantings, it should be safe to plant vegetables after a year. You could also use Avenger Herbicide and replant as soon as 2 weeks after application. The delay is just to be sure the target plants have had time to be killed before you till any roots that may still be viable.

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.

There is not a recommended pre-emergent that should be used with Roundup Pro Max. However, a product like Hi-Yield Killzall Extended Control may be a better option. This product provides both pre- and post-emergent control of weeds on areas such as sidewalks, fences, driveways, landscape areas, and walkways for 3-6 months when used according to label directions. It should NOT be applied to lawns. If you are targeting weeds in your lawn, please provide your desired turf species (include approx. size area of the lawn) and the targeted weeds for herbicide options that will not kill your turf.

If you are looking for a product with both glyphosate and a soil sterilant to prevent plant growth for up to a year, then we recommend Eraser Max.
