How it kills
EPSP synthase inhibitors
Blocks the shikimate pathway, which plants use to make essential amino acids.
Moves all through the plant, roots included. Slow but thorough.
Taken in by the leaf, then carried with sugars down to the roots and up to the growing points.
Where it fits
In the season.
Commonly used on
- Grassy weeds
- Broadleaf weeds
- Perennials
Good to know
- Hard water can tie it up. Check the label on water quality and additives.
- Pre-harvest use has crop stage and export-market considerations.
- Pair it with a second group against resistant kochia.
- Glyphosate-resistant kochia is widespread on the Prairies, so tank-mix partners from other groups matter.
