Product Q&A

Answer:

The Quali-Pro Prodiamine 4L Pre-Emergent Herbicide rate used is not set per gallon as the amount of water used is not as important as making sure to apply the correct amount of product over an area. You would use 0.23 to 1.1 fl oz per 1000 sq ft, which is normally 1 gallon water, depending on your lawn type. Please refer to the product label for complete instructions.
