Precautions

Glyphosate is a non-selective herbicide that will kill turf that is sprayed.
For actively growing weeds in the fall, or spring prior to planting (otherwise turf will be killed).
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 rate and notes for annual and perennial weed control, refer to Table 4-2.
