Drive XLR8 should be applied when crabgrass is actively growing and temperatures are between 65 and 85 degrees. For best results, a methylated seed oil surfactant ike Duo Stick should be tank mixed for better coverage and faster burndown of weeds. The product label states for consistent results, make Drive XLR8 application to newly germinated, to 1-tiller crabgrass, and when crabgrass has matured to 5 tillers or greater. Repeat application may be needed 21 days following the initial application. 

We apologize you are having difficulty eradicating the mature crabgrass with Drive XLR. Are you using a surfactant with your mixture? Are you using the highest application ratio you can for your turf? For the best crabgrass control, you want to apply a pre emergent in the spring. Please visit our pre emergent crabgrass control page.

Drive XLR8 Herbicide Crabgrassiller is labeled to be safely applied to Zoysia if used as directed.

You should keep your dogs off the treated area for 2-3 hours following the application. After the product has dried there should not be any issues with your dogs using the treated areas. We do recommend that you take the time to read the Drive XLR8 product label and MSDS before you pruchase the product as customers have different perceptions of what they feel is or is not safe for use on their property.

Unfortunately their is not a selective product that will remove crabgrass from St. Augustine.  St. Augustine is a very fragile grass, and so most selective products that are labeled to remove crabgrass and not your real grass, will hurt the St. Augustine.  It is recommended to kill the crabgrass with a round up type product, like Ranger Pro, which will also kill just the St. Augustine around the crabgrass that it is sprayed on, and then a couple weeks later re-seed those areas with new St. Augustine. 

For long term control though, you should apply a pre-emergent in the late fall and early spring which will prevent new crabgrass from coming up next year.  If you apply pre-emergent every year, you should not have issues with crabgrass long term.  Dimension 2EW is one of our most popular pre-emergents for crabgrass.

Depending on the type of fescue you have, Drive XLR8 Herbicide can be used at the time of seeding.  If you are overseeding with fine fescue, it is recommended that you use Drive XLR8 at least 7 days before seeding or 28 days after emergence of the new seed. If you are overseeding with tall fescue, Drive XLR8 can be used at any time. We do recommend using an MSO surfactant with this product as well. Please check the label for complete application instructions.
