DIRECTIONS FOR USE:
WHEAT, BARLEY, RYE
Treatment Stage: For ground or aerial application. Treat from the 3-leaf expanded to the early flag leaf or between the milk stage and full maturity stage of the crop.

OATS AND MIXED GRAIN
Treatment Stage: For ground or aerial application. Spray from 1 leaf expanded to the early flag leaf stage of the crop.

FALL RYE, WINTER WHEAT
Treatment Stage: For ground application only. Spring application only between full tillering and the shot blade stage. Do not apply to seedling winter cereals in the fall or during and after the flag leaf stage.

FLAX (Excluding low-linolenic acid varieties)
Treatment Stage: For ground application ONLY. Spray after plant reaches 5 cm in height and before the bud stage. Caution: Early crop injury may be observed, but yield should not be affected.
Established Grasses and Forage Legumes (Alfalfa, Alsike and Red Clover)
Treatment Stage: For ground application only. Apply very early in the spring, before the growth of perennial forages has begun. In pure stands of grasses, applications may be made in the fall (for susceptible winter annual and perennial weeds).

WEEDS CONTROLLED AND RATES OF APPLICATION
Susceptible Weeds:
Burdock (before the 4-leafstage), Cocklebur, Common plantain, Common ragweed, False ragweed, Flixweed*, Giant ragweed, Lamb’s-quarters, Mustards (except Dog and Tansy mustard), Prickly lettuce, Russian pigweed**, Shepherd’s purse**, Stinkweed, Vetch, Wild radish, Wild (annual) sunflower.
*Flixweed susceptible only at seedling stage. Use higher rate for fall germinated seedlings.
**Use higher rate only, on these species.

Rates to Use on Susceptible Weeds:
Small seedlings, good growing conditions: 580 mL/ha
Weeds in bud, dry or cool weather or heavy infestations: 900 mL/ha
For best results apply at the 2 to 4 leaf stage of seedling weeds when weeds are actively growing. Weed resistance increases with age.

Harder-to-Control Weeds:
Annual sow-thistle, Biennial wormwood, Blue lettuce*,Bluebur, Canada thistle*, Corn spurry*,Curled dock, Dandelion, Dog mustard, Field bindweed*, Field Horsetail*, Field peppergrass, Goat’s-beard, Gumweed, Hairy galinsoga, Hedge bindweed*, Hemp-nettle (before 4 leaf stage), Hoary cress*, Kochia, Lady’s-thumb*, Leafy spurge*, Oak-leaved goosefoot, Perennial sow-thistle*, Purslane, Redroot pigweed, Russian knapweed*, Russian thistle, Smartweed*, Sweet clover (seedling), Tansy mustard, Tartary Buckwheat.
*Top Growth Control Only
Rates to Use on Harder- to-Control Weeds:
Small Seedlings growing rapidly, good growing conditions: 1.05 L/ha
Weeds in bud, dry or cool weather, or heavy infestations: 1.50 L/ha
For best results apply at the 2 to 4 leaf stage of seedling weeds when weeds are actively growing. Weed resistance increases with age.
Maximum Rates of Application (Do not exceed the rates given for each crop as identified below):
Cereals (including spring and winter wheat, barley, spring and fall rye): 1.05 L/ha
Oats: 900 mL/ha
Flax: 700 mL/ha
Established Grasses and Forage Legumes (Alfalfa, Alsike and Red Clover): 1.65 L/ha
Use the dose recommended to control the weeds present. Rates applied above those recommended can result in significant crop injury and should only be used when injury can be tolerated, such as heavy infestations of harder-tocontrol weeds. Apply in warm weather when the weeds and crop are growing actively and the weeds are at a susceptible stage. Avoid application during drought or during exceptionally hot weather.
For cereals, oats, and flax, do not apply more than once per year. For established grasses and forage legumes, pastures, and rangeland, do not apply more than twice per year, with a minimum retreatment interval of 90 days
