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 0.50 - 1.45 oz per 1,000 sq ft (please read the product label for the exact usage rate needed for your application) . 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 0.50 - 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. Please contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.

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.

When using Drive XLR8 Herbicide Crabgrass Killer the active ingredient quinclorac has dissipation values that can range from 60 to over 500 days. Because quinclorac does not bind well to soil, some dissipation noted in field testing could be due to chemical testing. The persistence hazard of qunclorac is rated high (likely to take over 60 days to degrade to half of the applied concentration). We would recommend waiting an entire season before any grazing took place on the area that was treated for this reason.
