Echelon® Duo: fertilizer + pre-emergent herbicide + insecticide. 

Echelon Duo is an Australian first in weed and insect control manufactured by Indigo Specialty. It is a combination of an NPK fertilizer coated with oxadiazon and thiamethoxam so with one application you can feed your turf whilst also giving long-term control against turf insect pests and weeds. Also as it is a granular product there is no spray drift so is safer on bees than using spray applications. Please feel free to check out our free weed ID chart.

In each granule Echelon Duo comprises:

  • A 15-2-17 compound fertilizer;
  • Thiamethoxam, the active ingredient in Meridian® and a proven insecticide against scarab larvae and billbug and
  • Oxadiazon, the active ingredient in Oxafert® and Echelon®.

The label and MSDS are available in the turf protection section. Echelon Duo is ideal for use by councils, sports turf managers, and landscape contractors.
