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

Indigo Echelon Duo is an Australian first in weed and insect control. 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 it is safer on bees than spray applications. Please feel free to check out our free weed ID chart and our black beetle ID guide.

In the USA, this technology is widespread, and companies such as Knox Fertilizers produce a range of products based on Acelepryn and Dimension herbicide.

Each granule of Echelon Duo contains:

  • Firstly, a 15-2-17 compound fertilizer;
  • Secondly, thiamethoxam is an active ingredient in Meridian® and a proven insecticide. This works against scarab larvae and billbugs and last but not least
  • Oxadiazon, the active ingredient in Oxafert® and Echelon®. This is a highly effective pre-emergent herbicide.

The label and MSDS are in the turf chemical section. Echelon Duo is ideal for use by councils, schools, sports turf managers, and landscape contractors. Being a granule it does not need a spray tank to apply.

  5. Avoid contact with flowers and shrub and lastly
  6. Do not apply when daytime temperatures are consistently above 32°C.
