What is the usage rate for Quali-Pro Prodiamine 4L Pre-Emergent Herbicide?

I'm trying to spray in the next week here in the Memphis TN area. I have an acre of land and a 35 gallon tank sprayer. Do I need 1once per square feet? I have about an acre to cover.


The rates for Prodiamine 4L Herbicide will vary depending on the type of turfgrass you are treating, desired length of weed control, and how many applications you plan to make per year. You can apply a maximum of 10 oz – 48 oz per year per Acre, depending on your turfgrass. You can view application charts beginning on page 5 of the product label here.
