7 Top-Rated Pre-Emergent Weed Killers of 2024

Weeds are more than just an eyesore, these invasive plants can wreak havoc on your lush lawn. By aggressively competing for nutrients, moisture, and space, weeds deprive your grass of essentials for healthy growth. Some aggressive varieties like crabgrass and nutsedge even release toxic compounds that prevent surrounding plants from growing. 

The best defense to get rid of weeds is by using a pre-emergent herbicide. These specialized weed preventers create an invisible barrier that stops seeds from germinating in the first place. 

In 2024, innovative new pre-emergent formulas offer longer residual control, lower environmental impact, and incredible convenience to help you get your lawn back. 

From ultra-low-dose granular solutions to plant-safe liquid options, this guide covers seven of the top pre-emergent weed killers to preserve your picture-perfect lawn all season long.

This has been rated as one of the best pre-emergent weed killers by numerous websites and customers alike for years. 

The primary active ingredient is 65% prodiamine, which means you can apply this product in either spring or fall for season-long crabgrass prevention.
