Drive XLR8 is not recommended to be used in a hose end sprayer.
Drive XLR8 is not recommended to be used in a hose end application. The first thing you need to know when using a herbicide such as Drive XLR8 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 your risk damaging your lawn, use too little and you will not get adequate results. You will need to use 1.45 fl oz per 1000 sq ft. To decide how much water to use, you should mark a 1000 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 1000 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 fl oz of Drive XLR8 with for each 1000 sq ft that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either rainfall or by sprinkler) following the application.
As you probably know, Centipedegrass is a very sensitive species of turf so many products that eliminate the crabgrass and other weeds can also cause damage to your lawn. Hi Yield Atrazine is safe to be used on Centipede and it will suppress Crabgrass but may not completely eliminate it. It will also control a large variety of other broadleaf weeds. Tenacity is a great pre and post emergent herbicide that will control crabgrass along with many other types of weeds without harming your centipede lawn. Make sure to read the Tenacity label very carefully and mix exactly what is recommended as this is a strong product and mis-using it can cause temporary turf injury. When applying tenacity it is highly recommended to use a temporary turf colorant like Turf Mark Blue to allow you to see where you are spraying. Overlapping your application of Tenacity can cause temporary whitening of the lawn as well, but the color will return in 3-4 weeks at most. Please let us know if you have any other questions.
