Buying Guide

  • Weed spectrum: Consider whether you need broadleaf and grassy weed prevention, or target specific weeds like crabgrass and Poa anna. Some products emphasize broad control, others focus on key grasses.
  • Coverage area: Bags range from small 5-pound containers to 45-pound bulk, with coverage suitable for small lots or large pastures. Measure your area to choose the right quantity.
  • Active ingredient compatibility: Prodiamine and Dithiopyr-based products are common choices; verify compatibility with your existing turf species and fertilizer program.
  • Application timing: Many pre-emergents require application before weed germination in spring or fall. Check your local climate and moss or dew patterns to optimize timing.
  • Safety and compatibility: Review label directions for carrier (water-based, micro-cap), tank-mix options, and any restrictions for irrigation or mowing post-application.
  • Target grass types: Some products advertise broad compatibility with common grasses (Bahiagrass, Bermudagrass, Zoysia, Tall Fescue). Ensure the product suits your pasture’s grass mix.
  • Long-term strategy: For large pastures, consider a mix of products with different coverage and rotation to prevent weed resistance over multiple seasons.
  • Environmental and storage considerations: Store in a cool, dry place and keep out of reach of children and pets. Use containers within their shelf life for best results.
