Early Spring Pre-Emergent Control

Prodiamine is a pre-emergent herbicide that is economical, offers a low-dose application rate, and is highly effective against controlling over 30 grassy and broadleaf weeds including crabgrass, goosegrass and poa annua. Prodiamine is non-staining, and offers a wide range of application flexibility. A single application is all that is needed for season-long control, with many turfgrass professionals choosing to apply Prodiamine in the fall after soil temperatures retreat below 50°F. Prodiamine has the lowest water solubility and volatility and stays within the top one half inch of soil. For best results, apply Prodiamine at the minimum rate of .50-lb. A.I. per acre for control up to 12 weeks, 1.00-lb. A.I. per acre for up to 20 week control, and 1.50-lb. A.I. per acre for up to 32 week control.
The components of Prodiamine are not effective unless activated by a minimum .5 inch rainfall or overhead irrigation.
