Prodiamine is a pre-emergent used in spring and fall to stop problem grasses and weeds in lawns. It is best known as a crabgrass and poa annua pre emergent but is also stops other listed weeds including:
Barnyardgrass, Carpetweed-04, Chickweed (common), Chickweed (mousear), Crabgrass (large and smooth), Crowfootgrass, Cup grass (woolly), Foxtails (annual), Goosegrass, Henbit, Itchgrass, Johnsongrass (seedling), Junglerice, Knotweed, Kochia, Lambsquarters (common), Lovegrass, Panicum (browntop, fall and Texas), Pigweed, Purslane (common), Pusley (Florida), Rescuegrass, Shepherdspurse, Signalgrass Broadleaf, Speedwell (Persian), Sprangletop, Spurge (prostate), Witchgrass, Woodsorrel (yellow, from seed)
Since this is a professional formulation, there are several ways to parse the usage and rates. Our recommendation is to apply two applications in spring for crabgrass, known as “split applications” and each of those should be .183oz/1,000 sq ft (5.2g).
We recommend weighing product on a scale to be accurate and grams will be the easiest.
Mix 5.2 grams of prodiamine 65 WDG in 1 gallon of water and this spray mix can cover 1,000 sq ft.
For crabgrass apply in early spring as soil temps approach 50-55F
Apply a second application 35-45 days later as soil temps cross 65F
In fall, apply as soil temps fall to 70F coming out of summer. This is to prevent poa annua (annual bluegrass), henbit and chickweed.
