Buying Guide: Key Purchase Considerations
- Active ingredient and weed targets: Prodiamine-based products provide broad pre-emergent control, while Dithiopyr-based formulations also offer early season protection. Choose based on the weed pressures common in your region and the timing you prefer (fall vs. spring).
- Coverage and application rates: Check coverage per bag and needed application rates for your lawn size. Opt for products that match your yard’s square footage and mowing frequency to minimize waste.
- Lawn type compatibility: Some pre-emergents are better suited for cool-season grasses, while others work with warm-season varieties. Verify compatibility with your grass type (Bermuda, Zoysia, Fescue, etc.).
- Soil and watering considerations: DG technology improves dissolution and soil penetration. Ensure you water after application as labeled to activate the product effectively.
- Seasonality: Fall applications target winter annuals; spring applications address early germination. Planning for both seasons can provide year-round protection but review local guidelines and product labels.
- Fertilizer integration: Some products include fertilizer, offering a combined benefit. Consider whether you need additional lawn nutrition or prefer a separate fertilizer program.
- Environmental and safety notes: Follow label directions for storage, handling, and safety to minimize exposure to people, pets, and beneficial organisms in the soil.
- Label completeness: Always read the product label for the complete pest list, allowable turf types, and site restrictions to ensure proper use and effective results.
