Precautions (For more information, see Chapter 4. Herbicides Used in Ontario, page 23 and Chapter 5. Notes on Adjuvants, page 69).
- Apply to actively growing grasses.
- For annual grass, use 0.32 L/ha. Apply at the 1-6 leaf stage.
- For volunteer grains, use 0.47 L/ha.
- For quackgrass, use 1.1 L/ha. Apply up to the 3 leaf stage. Thorough preplant tillage will ensure more uniform quackgrass emergence. Cultivate after 7 days in wide row crops. Use the high rate of MERGE for quackgrass.

- Do NOT apply closer than 50 days to harvest.
