What Are The Pros And Cons Of Prodiamine Per emergent Hericide

Summary: Prodiamine is an effective pre-emergent herbicide that stops crabgrass and common weeds from appearing in lawns and landscaping. It can be used in granular form or sprayed, but spraying is considered more effective. While it may be initially expensive, it is more cost-effective in the long run. However, using a higher dose of Prodiamine can cause issues during fall overseeding. Professionals often recommend the Quali-Pro Prodiamine concentrate for weed control. Additionally, corn gluten meal is a natural, chemical-free option for preventing weeds. On the other hand, post-emergent herbicides like dithiopyr are used to kill weeds after they have emerged from the soil.
