Effects of Growing Conditions:
A moderate rainfall or equivalent irrigation (0.5 inches) is required within 10 days to activate pre-emergent surface
treatments. If rain does not occur, a shallow cultivation or use of a rotary hoe is necessary. Drought conditions that persist
after any application may reduce annual grass control. On sandy soils, heavy rainfall following application may cause
leaching of Dual II Magnum, resulting in reduced weed control.
Tank Mixes:
Herbicides:
• In Corn: AAtrex in both PPI and pre-emergent applications.
• In Soybeans: Sencor, and glyphosate, in both PPI and pre-emergent applications.
Fertilizers: May be applied with liquid fertilizer. May be impregnated onto dry bulk fertilizers (except nitrate fertilizers,
superphosphate fertilizers or limestone).
Insecticides: None registered.
Note: The above mixes are those listed on the Dual II Magnum label only.
Adding ingredients in the correct order is critical for optimum performance. Check labels of products to be mixed for
directions. General guidelines can be found on page 8.
Weed Control
Restrictions:
• Rainfall: When applying as a pre-emergent surface treatment, 0.5 inches (1.25 cm) of rain or irrigation is required after
application for proper activity.
• Re-entry Interval: DO NOT enter treated fields for at least 12 hours.
• Grazing Restrictions: DO NOT graze the treated immature crop or cut for hay. In corn, immature means before ear
emergence.
• Pre-harvest Interval: DO NOT harvest corn within 80 days of post-emergent application.
• Re-cropping Interval: In the year of treatment, seed only corn, soybeans, white beans, potatoes, snap beans, lima
beans, processing peas, sweet white lupins, or (a minimum of 4.5 months after application) winter cereals.
• Aerial Application: DO NOT apply by air.
• Storage: May be frozen.
• Buffer Zones: Leave a buffer zone of 29 metres between last spray swath and the edge of important wildlife habitats
such as wetlands, sloughs and water bodies.
Sprayer Cleaning:
No detailed cleaning procedures are indicated on the label. Use a commercial all purpose spray sprayer cleaning product for
adequate cleaning. Contact the manufacturer for more information.
Hazard Rating:
