Frequently Asked Questions

PAR III is for broadleaf weed control in lawns and maintained grass areas, while Roundup Transorb is for total vegetation control in non-lawn areas. Use PAR III when you want to treat lawn weeds while helping keep desirable grass intact when used as directed. Use Roundup Transorb where unwanted grass, weeds, brush, or invasive growth needs clearing.

Choose PAR III for broadleaf weed control for lawns. It is suited to common lawn weeds such as dandelions, clover, chickweed, thistle, plantain, and other broadleaf weeds when used as directed.
