Suppression
**
Most effective control with early application. Most kochia in Alberta has been found to be Group 2 resistant. Without testing to confirm, assume
kochia in your field is resistant and will not be controlled by this product alone

Mixing Instructions

Application Tips
Higher spray volumes are required for dense crop canopy and/or large weeds. Weeds should be less than 10 cm tall or
across at application. Effectiveness of Harmony SG may be reduced if it remains in the tank for more than 24 hours.
Do not use flood type nozzles, controlled droplet application equipment, spray foils or hollow cone nozzles. Do not
apply to crop stressed by conditions such as frost, low fertility, drought, flooding, disease or insect damage as crop
injury may result.
How it Works
Harmony SG is absorbed by the foliage and rapidly translocated to the growing points. Inhibits cell elongation in
broadleaf weeds. Thorough coverage of the plants is essential for consistent control.
Expected Results
Broadleaf weed growth stops immediately. Discolouration of dying weeds may be noticeable for 1 - 3 weeks after
application, depending on growing conditions and weed species. Grassy weeds - depending on the species, growing
conditions and crop competition - leaves and growing points turn yellow within 1 - 3 weeks after application. Poor
results may be expected if there is improper mixing, timing or coverage, or when weeds are under drought stress.
Restrictions
Rainfall
:
Rainfall within 1 hour of application may reduce weed control with Harmony SG.
Grazing
:
Wheat may be grazed 7 days after the application of Harmony SG.
Pre-harvest Interval
:
Do not harvest forage or cut hay within 60 days after application.
Re-cropping
:
Do not treat wheat underseeded to forages. Do not plant to any crop until 2 months after application.
