Using Surlan around KBG & Ryegrass lawns

[LIBERTYLANDSCAPING]

Been looking for some answers on using Surflan as pre-emergant in beds around KBG/Ryegrass lawns:confused: Surflan is labeled for TTT Fescue, but not for KBG/Ryegrass... Nothing on label says if it is damaging to these grasses is they come into contact with Surflan? Anyone know for sure?

Thanks in advance:)

Keep the surflan off kbg/rye. If you use it in a bed, you'll be fine. It'll stay put and not migrate into the lawn.
