Liquid Harvest Mesotrione — 8oz
Liquid Harvest Mesotrione is a post- and pre-emergent herbicide designed to target several broadleaf and grassy weeds. The active ingredient mesotrione is rapidly absorbed and begins working on contact, with full weed death typically noticed over 2–3 weeks. Water activation is essential, and applications may require 0.15 inches of additional water if rainfall is insufficient within 10 days. It is suitable for common Bermuda grass varieties when used on dormant bermudagrass to eliminate weeds. The product concentrates on a wide weed spectrum, including carpetweed, chickweed, crabgrass, dandelion, and more.

Buying Guide: Key Purchase Considerations
- Weed spectrum: Choose a product that targets the most troublesome weeds in your area, such as crabgrass, foxtail, and other annuals common to Bermuda grass lawns.
- Formulation and application: Liquid pre-emergents offer quick mixing and uniform spray coverage. Granular options may require irrigation and are often easier to apply in larger areas.
- Grass compatibility: Ensure the product is labeled for Bermuda grass and compatible with dormant or actively growing bermudagrass to avoid phytotoxic effects.
- Pre- vs. post-emergent balance: Some products provide both pre- and post-emergent action, while others are strictly preventive. Understand your weed pressure before selecting.
- Water activation and rainfall: Many pre-emergents rely on rainfall or irrigation to move into the soil. Plan applications around weather forecasts and irrigation schedules.
- Environmental and safety considerations: Check for pet safety guidelines, runoff considerations, and label restrictions for landscapes, gardens, and turf areas.
- Re-entry intervals and frequency: Review label guidance on when it is safe to re-enter treated areas and how often applications can be made within a season.
- Site-specific needs: For large yards or complex landscapes, consider products with DG technology or rapid dissolution to ensure even soil distribution and adequate movement into the root zone.
- Label adherence: Always follow the product label for rates, application timing, and compatibility with fertilizers or other lawn care products.
Overall, selecting the right liquid pre-emergent for Bermuda grass involves aligning weed targets with turf compatibility and environmental conditions. For best, long-term results, pair pre-emergent programs with lawn maintenance practices such as proper mowing height, irrigation management, and timely fertilization to minimize weed establishment and promote dense, healthy Bermuda grass growth.
