The label for Gordons Ornamec Over-The-Top mentions suppressing dallisgrass with a single Spring time application. I've also seen Fusilade II and Dismiss NXT recommended for dallisgrass suppression, but I don't find dallisgrass listed on those product labels. I know dallisgrass is difficult to control, but other than glyphosate, which herbicide is best for suppression in residential tall fescue yard?
Since dallisgrass is not listed on the product labels of the Fusilade or Dismiss NXT, we would not recommend using these products as results are not guaranteed. We strictly go by the product labels' information as the labels are law. Gordons Ornamec Over the Top Grass Herbicide has been discontinued. Gordons Ornamec 170 Grass Herbicide can be used as an alternative. You may view the product label here for more information and complete application instructions. The only other option that we carry other than non selective herbicides for a post emergent application would be a product called Pylex Herbicide which can be pretty expensive.
You could also consider doing a pre emergent application to prevent the dallisgrass from coming up in the first place. A product like Dimension 2EW would be a good option. You may view the product label here.
