Tank Mixes:
Herbicides:
• Prior to seeding registered crops (all products):
º Must be mixed with glyphosate.
• Fallow: All products
º Must be mixed with either glyphosate or 2,4-D ester.
• In spring wheat (including durum) and barley (Nuance, Inferno WDG, MPower X and Spike only):
º Assert (0.53 to 0.65 L per acre);
º Fenoxaprop (Cougar and Cordon only - 155 mL/ acre).
• In spring wheat (NOT durum) and barley (Nuance, Inferno WDG, MPower X and Spike only):
º Banvel II (44.5 mL/acre)
• Tribenuron Tolerant Sunflowers (Express SG only):
º Assure II (label rates) plus Merge or Suremix adjuvants.
Note: The above mixes are those listed on the tribenuron labels only.
Adding ingredients in the correct order is critical for optimum performance. Check product labels for directions. General
guidelines can be found on page 8.
Restrictions:
• Rainfall: Within 6 hours will reduce control.
• Re-entry Interval: DO NOT enter treated fields for 12 hours.
• Grazing Restrictions:
º 75% WDG formulations: DO NOT graze treated crops within 30 days of application.
º Express SG: Forage may be grazed immediately following application.
• Pre-harvest Interval:
º 75% WDG formulations: Leave 60 days between spraying and harvest of cereals.
º Express SG: Leave 70 days between spraying and harvest of sunflower.
• Re-cropping Interval: There are no restrictions one year after treatment.
º 75% WDG formulations: Canola, flax, lentil and alfalfa may be planted 2 months after application.

Application method
Buffer Zones (metres † ) Required for the Protection of:
Aquatic Habitats of Depths
Terrestrial habitat
Less than 1 m
Greater than 1 m
Fallow, preseed, range and pasture 1 0 4
Tribenuron tolerant sunflowers 0 0 3
See page 35 for an explanation of the different habitats.
* Buffer zones can be reduced by 70% when using shrouds and by 30% when using cones mounted less than
12 inches from the crop canopy.
†
Distance is measured from the downwind edge of the boom to sensitive areas.
Sprayer Cleaning:
Tribenuron can cause severe injury to sensitive crops at very low concentrations. Sprayers used to spray Tribenuron should
be flushed out immediately after use. Refer to ‘Method A’ in the general section on sprayer cleaning on page 9 and 10.
This ammonia rinse process should be done twice for the WDG formulations. See the labels of the various products for
specific instructions. The addition of detergent may improve cleanout, especially when mixing with other products.
