Precautions (For more information, see Chapter 4. Herbicides Used in Ontario, page 23 and Chapter 5. Notes on Adjuvants, page 69).

For actively growing weeds in the fall, or spring prior to emergence of any crop.
Allow 5-7 days translocation time after application before doing any tillage when conditions are good. If cool temperatures follow application, allow additional time for translocation to be completed before disturbing treated weeds.
Only weeds emerged at application time will be controlled. Additional weed control programs will be necessary to control weeds germinating later.
Repeat application to regrowth may be necessary for complete control.
For specific information on product rates and notes for annual and perennial weed control refer to Table 6-3 . Postharvest Weed control Ratings, page 83.

*See Table 4-1. Herbicides Used in Ontario, page 23, for formulations available. See label for specific uses and rates.
