LESCO offers a wide range of specialized weed control products designed to kill weeds without harming established turfgrass. 


What Are Post-Emergent Herbicides?

Post-emergent herbicides are designed to target weeds that are already actively growing. Unlike pre-emergent, which creates a chemical barrier in the soil to stop seed germination, post-emergent herbicides are applied directly to visible weeds to stop them from growing and spreading. These products are ideal for spot treatments and curative applications, helping turf managers respond quickly and precisely when weeds appear. 


Why Use Post-Emergent Herbicides

  1. Control Breakthrough Weeds
    Even the best pre-emergent program can’t catch everything. Post-emergent herbicides are your backup plan – and often your first line of defense when weeds emerge.
     
  2. Target Specific Weeds
    Post-emergent herbicides allow for selective treatment of a wide range of weed species, including broadleaf weeds, grassy weeds and sedges. LESCO’s portfolio includes options that target hard-to-control species like crabgrass, dandelion and clover without damaging turf. 
     
  3. Flexible Application Timing
    Post-emergent herbicides can be applied throughout the growing season, providing the flexibility to respond to weed pressure as it happens. Whether you’re treating cool-season or warm-season turf, there’s a LESCO solution that fits your timing, region and turf type. For more information, check out our Turf Calendars on application timing in your area.
     
  4. Enhance Turf Aesthetic and Health
    Weeds compete with turfgrass for light, water and nutrients. Using post-emergent herbicides can eliminate visible weeds to help improve both the visual appeal and the vigor of the turf.
