Crabgrass in New Bermuda Seed: Quinclorac Is the Answer

Mid-May Bermuda seeding. Crabgrass invading. Told not to treat—might hurt new grass. What's safe and effective?

Quinclorac: Selective for Crabgrass in Bermuda

Products with quinclorac (e.g., Drive XLR8, Quinclorac 75DF) control crabgrass in established and newly seeded Bermuda (check label for minimum leaf stage). Follow directions exactly—rate, timing, adjuvant.

Key Points

• Apply when crabgrass is 1–3 leaf (tiller stage less responsive).
• Bermuda should be at least 2–3 true leaves (usually 3–4 weeks post-emergence).
• Add methylated seed oil (MSO) surfactant for best uptake.
• Do not mow 2 days before/after application.

Don't wait. Early control prevents crabgrass from seeding and dominating.
