Pro Tips
Pro Tips & Quick Tricks

Prodiamine 65 WDG is a pre-emergent. As a crabgrass and noxious weed killer, apply Prodiamine 65 WDG before crabgrass emerges. If you wait until after crabgrass emerges, it is too late because these weeds will drop seed pods that will lay dormant for the following year. Refer to the germination chart.
Also, if Pao annua (a grassy weed) is an issue in the winter, you will receive outstanding results if you tank mix it with Negate 37 WG. Use Negate on warm-season grass turf only.
