Question

When using Drive 75 DF herbicide, how many ounces of Drive should be used per 1 gallon of water when using a 2.5 gallon hand sprayer? Also, how many ounces of crop oil should be used per 1 gallon of water? The label tells me to totally wet the weeds -- is this correct?

Answer

Everyone has questions. And BASF Professional Turf has answers.

Use rates for Drive are determined by the amount of product per 1,000 sq ft. The standard use rate is .367 ounces per 1000 sq ft. In my experience when using a backpack or pump-up sprayer I have determined that the water volume applied is usually about 2 gallons per 1000 sq ft. This means you should add .367 ounces to 2 gallons of water and spray to wet. In order to really know how much water your sprayer delivers per 1000 sq ft, I suggest that you mark off an area (10 x 100 ft=1000 sq ft) on a driveway or parking lot and spray as you normally would. Determine how much water you used. This is your application volume per 1000 sq ft. You can now add the right amount of Drive to the tank. The methylated seed oil rate is .55 ounces per 1000 sq ft, so for each .367 ounces of Drive that you add, mix in .55 ounces of MSO. Thanks for your question.
