How much Dithiopyr 40 WSB you use depends on the program you going to use but the amount is not easily measured out for smaller areas since it is in premeasured pouches. The max rate on the label states: Do not apply more than 0.5 lb ai/ acre per application or more than 1.5 lb ai/acre per year using split or sequential applications.
A better option if you have less than an acre to treat would be the liquid version Dimension 2EW. You will use .33 - .73 of an ounce of Dimension 2EW per 1,000 sq ft. The exact usage rate will depend on your location and the application program you choose. Please refer to pages 4-6 of the product label to find the exact usage rate for your needs.
