Introduction

300
Weeds Suppressed:
º Canada thistle**
º Lamb’s-quarters
(up to 3 in (8 cm))
º Russian thistle
º Sow-thistle
(annual, perennial)**
º Toadflax º Wild buckwheat
(up to 3 leaf)
* CLEARFIELD varieties will be controlled only with the addition of 2,4-D or MCPA.
** Apply when thistles are less than 6 inches (15 cm) tall.
Refer to the product label for complete mixing instructions. A general guide to mixing can be found on page 8.
Application Information:
• Water Volume: Minimum 40 L per acre.
• Nozzles and Pressure: No application pressures are recommended by the manufacturer. Typical application pressures
for standard flat fan nozzles are from 35 to 40 psi (240 to 275 kPa). Low drift nozzles may require higher pressures for
proper performance. Use nozzles and pressures designed to deliver proper coverage with ASABE medium droplets.
• Screens: Use a 50 mesh and filter system.
How it Works:
Refer to Table 9 on page 48.
Effects of Growing Conditions:
Metsulfuron may injure crops stressed by heavy rainfall, prolonged cool weather, frost conditions, wide fluctuations in day/
night temperatures, drought, or water-saturated soils, either before or after application. Weed control will be reduced under
dry, cold conditions.
Tank Mixes:
DO NOT mix the soluble bags with any substance containing boron which releases chlorine.
Herbicides:
• In wheat and barley:
º 2,4-D Amine or Ester (170 to 227 g ae per acre – refer to 2,4-D page), plus surfactant*.
º MCPA Amine or Ester (0.23 to 0.38 L per acre – 600 g/L formulation), plus surfactant.
• In creeping red fescue:
º Assure II (0.2 to 0.3 L per acre) plus Sure-Mix adjuvant*.
* Use with the 3 g per acre rate of metsulfuron only.
Consult tank mix partner labels for additional crop staging and variety restrictions.
Insecticides: None registered.
Fungicides: None registered.
Fertilizer: None registered. DO NOT mix the soluble bags with fertilizers.
Note: The above mixes are those listed on the Metsulfuron labels only.
E.I. duPont Canada also supports the following mixes that are not on the Ally label. Apply mixes according to the most
restrictive use limitations for either product:
Herbicides: Puma Advance, Horizon NG
Adding ingredients in the correct order is critical for optimum performance. Check labels of both products to be mixed for
directions. General guidelines can be found on page 8.
Restrictions:
• Rainfall: Rain within 4 hours of application of tank mixes with 2,4-D amine, 2 hours of application of tank mixes with
2,4-D ester, will reduce weed control.
• Re-entry Interval: DO NOT enter treated fields for 12 hours.
• Grazing Restrictions: No restrictions.
