Dithiopyr L Herbicide


Walt Cline - Pest Control Professional Pro Tip: "Dithiopyr L works as a pre-emergent for annual weeds and pre-emergent and early post-emergent on crabgrass, so if you are a little late applying it don't fret. Dithiopyr L will still kill the crabgrass. This makes it a perfect choice in areas where the weather is unpredictable. Compare the ingredients to Dimension 2EW It's just as effective and and costs a little less."

Quali-Pro Dithiopyr L Herbicide - 1 Gallon

Quali-Pro Dithiopyr L, with Dithiopyr 22 % is a generic of Dimension EW Herbicide. Dithiopyr L is a pyridine-based herbicide. It provides pre emergence and early post emergence control of crabgrass and other broadleaf weeds and annual grasses. It may be applied in non-cropland, established lawns, ornamental turf (including golf tees, fairways and roughs), commercial sod farms, industrial sites, container-grown ornamentals, field-grown ornamentals, and landscape ornamentals.

Dithiopyr L Herbicide & Crabgrass Control

As a pre-emergent and early post emergent herbicide, Dithiopyr L will control crabgrass that has emerged up to the tillering stage. The tillering stage is the start of crabgrass visibility with no more than 5 leaves per plant.

Applications of Dithiopyr L after the initiation of tillering would not result in suitable control. All other applications of this product for target weeds should be made preemergence (prior to germination of target weeds).

Quali-Pro Dithiopyr L is to be used before broadleaf weeds or grasses are established, (except for crabgrass prior to tillering stage of growth).

  • Pre-emergent and early post-emergent herbicide
  • low mix rate
  • non-staining formulation (excellent alternative to Surflan or Oryzalin)

Tank Mix

    • Dithiopyr L may be mixed with Quali-Pro Isoxaben 75 WG or Gallery 75 DF to control listed broad leaves in ornamental areas as a pre-emergent.
    • It may be tank mixed with glyphosate for undesirable vegetation in ornamental areas, providing post emergent control of vulnerable listed weeds. Since Glyphosate is a non-selective herbicide, do not use on desired vegetation.

The use of a nonionic surfactant may improve control.
