Buying Guide: Key Purchase Considerations

  • Active ingredient and mode of action: Choose products with proven turf-targeted fungicides or organic options for specific diseases like brown patch, dollar spot, or powdery mildew. Consider copper-based or OMRI-listed formulations for organic gardening needs.
  • Scope of coverage: Assess square footage coverage and whether the product is ready-to-use or requires mixing. For large lawns, products with hose-end sprayers or concentrated formulations may offer convenience and efficiency.
  • Safety and turf compatibility: Ensure the product is labeled for lawn use and does not harm ornamentals nearby. Organic options may appeal to families with pets and kids, but always follow label directions to prevent phytotoxicity.
  • Application timing: Disease pressure can vary by season and climate. Plan applications to coincide with optimal disease progression windows and avoid stressful weather conditions that could reduce effectiveness.
  • Environmental impact: If pollinator safety or soil health is a priority, favor products with lower residual impact and those approved for organic gardening where appropriate.
  • Integrated lawn care strategy: Fungicides work best when integrated with proper mowing, irrigation, and fertilization practices. Address thatch buildup, avoid overwatering, and monitor for recurring symptoms to adjust treatments as needed.
  • Label compliance and local regulations: Always follow label directions, including pre-harvest intervals for any edible crops grown nearby and any local restrictions on copper-based products or pesticides.
