Mixing Instructions
Use mixing instructions “b” on page 13. First add the tank mix partner then the pH adjuster, then the Assert/Avert.
Use one package of spray water pH adjuster per jug of Assert/Avert.
Application Information
How to Apply
:
Ground applications only.
Do not apply by air.
Water Volume
:
Cereals: 20 - 40 L/acre. Note: Use Assert with pH adjuster (one bag per 10.8 L jug) or poor weed
control may occur. For ground-driven pump systems, ensure spray water pH adjuster is dissolved before engaging
pump.
Application Tips
Do not apply Assert/Avert within 5 days of any herbicide that is not a registered tank mix. Do not make more than
one application of Assert per growing season. Do not apply Assert/Avert to the same field in two successive years.
Do not spray Assert when freezing temperatures are forecast.
Note
:
the additive effect of soil residues from the use
of Assert 300SC herbicide and Ally, Curtail M, Odyssey, Pursuit or Prestige herbicides on the same land has not been
determined.
How it Works
Absorbed by foliage and roots and translocated to the growing points in the plant. Disrupts plant metabolism, causing
growth to stop in susceptible plants. Works best at warm temperatures. Do not apply to drought-stressed sunflower.
Expected Results
Absorbed through the foliage and roots of wild oats, wild mustard and stinkweed, wild buckwheat, and tartary
buckwheat plants. Susceptible plants stop growing soon after spray application. Obvious signs of plant death may not
be seen in some plants until 2 weeks later but the competitive effect of these plants will have been removed. Death
may not occur for several weeks.
Restrictions
Effect of Rainfall
:
Do not apply if rain is predicted within 6 hours.
Grazing
:
Do not graze treated fields or cut treated forage for silage or hay; sufficient data are not available to
support such use. (Barley, wheat grain or straw from fields treated with Assert can be fed to livestock.)
Re-cropping
:
Rotation to the following crops can be made.
One-year after application:
Black and Grey Wooded soil zones
:
spring wheat, durum wheat, barley, sunflower, canola, flax, peas.
Brown and Dark Brown soil zones
:
spring wheat, durum wheat, barley, sunflower, and CLEARFIELD canola.
Two years after the application
:
Following crops can be grown in all soil zones: spring wheat, durum wheat, barley,
sunflower, peas, canola, flax, oats, canary grass. Conduct a field bioassay before planting lentils and sugar beets.
Note:
The additive effect of soil residues from the use of Assert and Ally, Curtail M and Prestige on the same land
has not been determined. Crop rotation guidelines and minimum rotation intervals are not known and injury to
rotational crops other than wheat (excluding durum) may occur. Where these herbicides have been used, plant only
wheat (excluding durum) until a bioassay demonstrates that other crops can be successfully grown.
