Drive XLR8 is not labeled to treat for Sandburs. The best method of treatment for Sandburs is with a pre-emergent before the Sandburs germinate. A good option for a pre-emergent would be Surflan AS Herbicide but please refer to the product label to be sure it's safe for the type of grass you have. You can check Ferti-Lome Weed Out with Crabgrass Killer, it is labeled for Goathead which is another name for Sandbur, please refer to the product label to be sure it's safe for the type of grass you have.
With the type of grass you are seeding with (Kentucky Bluegrass) according to the chart on the label you may either apply Drive XLR8 7 days prior to seeding or 28 days post seeding.
Drive XLR8 Herbicide Crabgrass Killer is labeled to control bindweed, however it should only be applied in listed established turf. We currently do not offer a product that will selectively work as a post control for morning glory (bindweed) in junipers. You would need to hand pull or carefully spot treat with a non selective herbicide.
Drive XLR8 can be applied to Common Bermuda grass before seeding, at seeding, and 7-28 days after it emerges per the product label. Please refer to tables 1 & 4 on the label for more information.
Drive XLR8 Herbicide Crabgrass Killer is not labeled for crowfoot grass. For crowfoot, it is generally recommended to treat with a pre-emergent product. Something like Ferti-Lome Weed and Feed with Dimension would be an excellent option. This will be used either in early spring or in the fall.
For the weeds that are there now, we would recommend spot treating with a glyphosate product and reseed/sod the areas. This will kill whatever it comes in contact with.
When applying herbicides, including Drive XLR8 Herbicide Crabgrass Killer, it is not recommended to use a hose-end sprayer. It is better to use a hand pump or backpack sprayer to ensure the most accurate application.
How soon you can apply Drive XLR8 Herbicide Crabgrass Killer after seeding depends on the lawn species you planted. It appears Eco Lawn is a blend of fine fescues and the Drive XLR8 label states to not apply within 4 weeks after seedling emergence of this type of grass. You should wait until the grass is well established and has been mowed at least twice before applying Drive XLR8.
