Aatrex 480 (Corn only)
Dual II Magnium: 0.5 - 0.7 L/acre + Aatrex 480: 0.85 - 1.25 L/acre + non-ionic surfactant: 0.1% v/v
Application Information
How to Apply
:
Apply with ground equipment: band or overall spray.
Water volume
: 28 - 56
L/acre.
Incorporation
:
Incorporate to 5 cm. Do not exceed this depth since product dilution can occur. If using tandem discs,
set to cut to a depth of 10 cm operated at 6 - 9 km/h. If using vibrating shank cultivators with overlapping sweeps, set
10
cm deep and operate at 10 - 13 km/h. Spike tooth or diamond tooth harrows are good incorporation equipment.
Immediate incorporation is not necessary although desirable.
Application Tips
For band treatments, use a press wheel ahead of the nozzle to level the band.
How it Works
Inhibits germination, particularly grasses.
Expected Results
Annual grasses do not germinate or under dry conditions, may die back soon after emergence.
Restrictions
Rainfall
:
Moisture required to move chemical to area of germination but an excess may move it below this area.
Grazing
:
Do not graze treated immature crops or cut for hay. Sufficient data are not available to support such use. In
the case of corn, immature means before ear emergence.
Preharvest Interval
:
Do not harvest corn within 80 days, asparagus 16 days, sweet corn 50 days of making a post-
emergent application. Make only one application per season.
Recropping
:
Winter cereals may be seeded 4.5 months after treatment.
Environmental Precautions
Dual II Magnum is moderately to highly toxic to aquatic organisms. Avoid contamination of aquatic systems during
application. Leave a buffer zone of 29 m between the sprayed area and the edge of any sensitive habitats.
Runoff
:
Reduce the possibility of runoff from treated areas through the use of recommended buffer zones.
Toxicity
Ingestion: Slightly toxic. Acute oral LD
50
(
rat) = 2,149 mg/kg. Dermal: Slightly toxic.
Storage
Heated storage required.
