Spray CDA

We had great weed control with the Highways Weedmaster ATV. The overall weed control was the best we’ve known especially on the difficult cobbled streets, where we usually struggle using knapsacks.

Application Information

When to Spray?

Spray when weeds are actively growing and have adequate leaf area to absorb the spray. Perennial grasses are susceptible when tillering and new rhizome growth commences (normally 4-5 leaves). Perennial broad-leaved weeds are more susceptible if treated at or near flowering, but will be severely checked if treated at any time during active growth.

Application Rate

Area Treated Weeds CDA Vanquish Biactive
1 Hectare Perennials 15 Litres
1 Hectare Annuals 9 Litres
500m² Perennials 0.75 Litres
500m² Annuals 0.45 Litres

Optimising CDA Vanquish Biactive

  • Ideally treat perennial weeds before flowering
  • Symptoms on weeds take 7 to 21 days depending on species
  • To obtain optimum weed control, leave the weeds undisturbed.


CDA Vanquish Biactive leaves no harmful residues in the soil, so land can be used for re-planting 7-10 days after application. Grasses may be sown 14 days after treatment.
