Is is product safe to use on a white clover, Tall Fescue, & Annual Ryegrass lawn? I don't see Clover or ryegrass called out on the datasheet, so just want to double-check! Also is this effective on horseweed (Erigeron Canadensis) and/or Sandbur grass (Cenchrus Longispinus).
Prodiamine 65 WDG (Generic Barricade) does list perennial ryegrass and tall fescue as tolerable to applications on the label. This is a pre-emergent only that will not affect any actively growing weeds and only prevents the weeds listed on the label when applied before they germinate which does not include sandbur or horseweed. Something like Pendulum 2G would be more recommended for Sandbur. We are not able to find a pre-emergent labeled for horseweed.
