Drive XLR8 Herbicide Crabgrass Killer - Questions & Answers

You can use 63 oz of Drive XLR8 Herbicide Crabgrass Killer in a minimum of  20 gallons of water to cover an acre (add MSO to mixture per label instructions). 
 

If you were wanting to use the drive for crabgrass and other broad leaf post emergent weed control across the entire 8-10 acres as a broadcast spray, you would need roughly 4 half gallons of the product. 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. 

Drive XLR8 Herbicide Crabgrass Killer states on the product label DO NOT irrigate the area for 24 hours after the application. If rainfall does not occur 2-7 days after the application, irrigation of at least 1/2 inch of water is desirable.

There is not a specific amount of time you need to wait to apply your fertilizer after applying Drive XLR8 Herbicide. Since Drive works best when it has at least 24 hours to dry after application, then waiting at least 1 day before watering or applying a liquid fertilizer would be advantageous.
