Learn more about Prodiamine WDG. I use it yearly to prevent Crabgrass and other weeds!
How much water per oz of prodiamine? It actually doesn’t matter. What matters is how much water it takes to evenly apply across your lawn. Some sprayers will apply more or less liquid so I’ll spray my entire lawn with just water, and then measure how much it took. I’ll then mix the prodiamine in to that amount of water to apply. After applying you need to water it in – about a half inch of water.
