How it kills
Glutamine synthetase inhibitors
Blocks the enzyme plants use to deal with ammonia, which then builds up to toxic levels.
A contact burn, visible within days.
Works where the droplet hits, with little or no movement through the plant. Coverage decides how well it works.
Where it fits
In the season.
Commonly used on
- Broadleaf weeds
- Grassy weeds
- Canola
Good to know
- Coverage is everything. Water volume and nozzle choice matter.
- Heat, humidity and sunlight generally help it work.
- Often paired with a Group 1 add-in for grassy weeds in canola.
- Water volume and coverage matter, because it does not move far in the plant.
