Introduction

Postemergence - Leaf stage of the weeds is critical for good weed control. Smaller weeds are generally easier to kill but there needs to be enough leaf surface to intercept the herbicide. Apply according to recommended leaf stages. Crop stage is important to optimize crop safety. Adjuvants will frequently improve the weed control when used as directed. Weather or other conditions may influence the optimum rate of adjuvant, see the product label for more details. Always use appropriate drift management technology.

Precautions

• 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 4-2.
