Drive XLR8 Herbicide Crabgrass Killer - Questions & Answers

Drive XLR8 Herbicide Crabgrass Killer is applied at 63 oz in 20 gallons of water to cover 1 acre. It is recommended to mix Drive XLR8 with either Dyneamic Surfactant or Prime Source Duo Stick. 

You want to make sure to use the diluted solution within 24 hours of mixing. The shelf life in the original bottle is 3 years.

In a 40 gallon tank you would add 64 oz of Drive XLR8 and 10 oz of methylated seed oil surfactant, and this should just about cover 1 acre. Keep in mind that it is most important to use the correct amount of product for the area you are treating, rather than an exact amount of water.

Drive XLR8 Herbicide Crabgrass Killer has a three year shelf life from the date of purchase if stored in a cool, dry place away from extreme temperatures. Once mixed with water and surfactant it should be used within 24 hours of mixing.

The first thing you need to know when using an herbicide such as Drive XLR8 Herbicide is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 1.45 oz per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 1.45 oz of product with for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application.

It is best to give Drive XLR8 at least 24 hours of dry time after application.  The product label recommends that if it has not rained within 2-7 days after application, you would then irrigate with at least 1/2 inch of water. 

The single application maximum rate for Drive XLR8 Herbicide is 1.45 oz per 1000 sq ft, or 64 oz per Acre. The product label gives instructions for split applications depending on the type of annual grass you are treating.  Otherwise the full rate would be used for most applications.

 Drive XLR8 is applied at 63 fl oz in 20 gallons of water to cover 1 acre (add a MSO or equivalent to the mix for more effective control-we offer Duo Stick or DyneAmic).

Please refer to the product label for full application instructions here. 

When using Drive XLR8 Herbicide Crabgrass Killer for crabgrass, it’s best to apply at either the very young stage or the most mature stage of the crabgrass.  When treating between the 2-4 tiller stage, repeat application may be required.  You should make your applications while temperatures are between 65 and 85 degrees for best results.  You can also use a pre-emergent like Dimension 2EW in the spring and the fall to help prevent it from coming up the following season.
