Introduction

Weeds, Rates and Staging:
Tribenuron/Metsulfuron at 7 g per acre (one container treats 80 acres) plus glyphosate at a rate equivalent to 180 g ae
per acre (equivalent of 0.5 L per acre of a 360 g per L formulation):
• Weeds controlled by glyphosate products at these rates plus up to 3 inches (8 cm) unless otherwise indicated:
º Canada thistle
º Narrow-leaved
(rosettes)**
hawk’s-beard †
º Cleavers †
º Night-flowering
º Cow cockle*
catchfly**
º Dandelion *** †
†
Residual control
* Up to the 3 leaf stage
** Suppression only
*** Up to 6 inches
º Scentless
chamomile
º White cockle
(rosettes)
º Volunteer canola
(including
glyphosate
tolerant
varieties)*** †
Tribenuron/Metsulfuron may degrade if left in the sprayer for an extended period. Apply within 24 hours of mixing.
Maximum one application per year of Express Pro, Nuance Pro or other products containing tribenuron or metsulfuron.
Refer to the product label for complete mixing instructions. A general guide to mixing can be found on page 8.
Application Information:
• Water Volume: 22 to 45 L per acre.
• Nozzles and Pressure: Use a combination of nozzles and pressure designed to deliver thorough, even coverage with
ASABE medium droplets. Low drift nozzles may require higher pressures for proper performance.
• Screens: Use 50 mesh or larger screens in both nozzles and in-line filters.
How it Works:
Refer to Table 9 on page 48.
Effects of Growing Conditions:
Registered crops seeded following Tribenuron/Metsulfuron application become stressed by drought, low fertility, saline
soils, waterlogged soils (soils at or near field capacity), disease or insect damage may be injured. This injury may be
worse on light or low organic matter soils. Weeds hardened off by environmental stress such as those above may not be
adequately controlled.
Tank Mixes:
Herbicides:
• Must be mixed with glyphosate.
Fungicides: None registered.
Fertilizers: None registered.
Insecticides: None registered.
Note: The above mixes are those listed on the Tribenuron/Metsulfuron 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: No rainfast period is specified on the label; required interval may be up to 8 hours. Contact manufacturers for
more information.
• Re-entry Interval: Wait 12 hours before re-entering treated fields.
• Re-cropping Interval: Barley and wheat (spring, winter and durum) may be seeded a minimum of 24 hours after
application. Oats may be seeded the season following application. Canola, flax and peas may be planted 10 months
following application. Lentil may be seeded 22 months following application.
• Aerial Application: DO NOT apply by air.
