What is the recommended rate for Prodiamine 65 WDG (Generic Barricade) to treat 3585 sq ft of bermudagrass lawn for crabgrass and poa annua (annual bluegrass) weed control? I am located in Northern Texas and using a 2 gallon sprayer.

Answer:

On Bermudagrass you can use up to 2.3 lbs of Prodiamine 65 WDG per acre per year, which breaks down to 0.83 oz per 1000 sq ft. You can split up this amount into as many applications as needed. So if you are doing applications in Spring and in Fall, then your maximum rate at those times is 1.15 lbs/A (0.415 oz/1000 sq ft). For Poa Annua (annual bluegrass) prevention: Applications in late summer or early fall before just before soil temperatures reach 70 degrees. For Crabgrass prevention: Applications in late Winter/early Spring before soil temperatures reach 55 degrees to prevent crabgrass. In a warm place like Texas, you will probably want one application in late Feb or March and then a second application 6-8 weeks later. If you are doing this, then you would lower that Spring rate to 0.2 oz per 1000 sq ft.

You can use this online tool to check soil temperatures for your area at any time.
