Buying Guide

  • Weed spectrum and target: Choose products that address both sandburs and common lawn weeds (nutsedges, broadleaf weeds, and crabgrass). Some formulations emphasize sedge control, while others are broadleaf focused.
  • Turf safety and labeled grasses: Look for safeners or labels that confirm compatibility with your lawn grass (St. Augustine, zoysia, bermudagrass, fescue, etc.).
  • Seeding and renovation: If you plan to overseed or establish new turf, select products compatible with seeding, such as Tenacity, which can be applied during seeding.
  • Application rate and frequency: Review recommended rates (per acre or per acre-equivalent) and the number of applications allowed per season to avoid turf stress.
  • Tank-mix compatibility: Some products perform best when used in combination with other herbicides for broader control, such as pairing with Turflon Ester Ultra for dollarweed control.
  • Non-target safety and environmental considerations: Consider impacts on nearby landscapes, water sources, and pets. Follow label directions to minimize risk.
  • Use site considerations: Residential lawns, airports, cemeteries, commercial properties, and public landscapes may have different label constraints; verify site-specific approvals on the label.
  • Cost and availability: Evaluate per-area cost and supplier reliability, especially for large-area projects or ongoing lawn care programs.
