Depending upon where you are located in the country and what type of turf you have, you are generally going to want to do a split application of Prodiamine 65 WDG twice a year to get a longer residual that will last year round. You can use anywhere from 0.5 lbs-0.75 lbs per application, once in the spring and once in the fall. If your 300 gallon tank covers 4 acres then you could use anywhere from 2-3 lbs per 300 gallons per application doing two applications per year.

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 0.185-.055 oz (1.1 tsp-3.3 tsp) of product with for each 1,000 sq ft area that needs to be treated.

Prodiamine 65 WDG is a great pre-emergent for prostrate spurge only, and there is a long list of tolerant ornamentals starting on page 15 of the product label. There are several types of Jasmine, Juniper, and sedum listed as tolerant. You may want to consider using Snapshot in your ornamental beds, instead, though. This pre-emergent label lists over 300 tolerant ornamental species and will prevent several types of spurge including both prostrate and spotted spurge. You can apply either of these products in Spring or Fall, although you definitely want to apply in Spring and possibly again in mid-summer for spurge prevention. Spurge also prefers high moisture areas, so be sure you address any drainage issues to help prevent this weed from thriving. Keep in mind that pre-emergents will only prevent new plants from germinating, not kill existing plants.
