DIRECTIONS FOR USE:
Do not re-enter treated fields until 12 hours after application DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes. Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty.
DO NOT apply with spray droplets smaller that the American Society of Agricultural Engineers (ASAE) medium classification. Boom height must be 60 cm or less above the crop or ground.

Buffer Zones: 
The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrublands), sensitive aquatic habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs, wetlands and estuarine/marine habitats).
When a tank mixture is used, consult the labels on the tank-mix partners and observe the largest (most restrictive buffer zone of the products involved in the tank mixture. 

WARNINGS:
DO NOT APPLY BY AIR. APPLY WITH GROUND EQUIPMENT ONLY. DO NOT make more than one application of AVERT Herbicide per growing season. DO NOT apply Avert Herbicide to the same field in two successive years. DO NOT spray AVERT Herbicide if rain is predicted within 6 hours. DO NOT spray AVERT Herbicide when freezing temperatures are forecast. 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 AVERT Herbicide can be fed to livestock.)

MIXING:
Fill the spray tank 3/4 full with clean water. Add 1 package of Spray Water pH Adjuster per jug of AVERT Herbicide to your tank water before adding AVERT Herbicide. Shake AVERT Herbicide well, then add required quantity of AVERT Herbicide while agitating. When AVERT Herbicide is thoroughly mixed fill remainder of tank with water while agitating. To ensure thorough mixing circulate the spray mixture in the tank for 5 minutes before spraying begins.

INSTRUCTIONS FOR TANK-MIXING: 
(2,4-D Ester, MCPA Ester, ATTAIN, CURTAIL M, ESTAPROP Plus, ESTAPROP XT, PRESTIGE, CORDON or PUMA 120 SUPER HERBICIDE, REFINE EXTRA, REFINE SG, TURBOPROP, DICHLORPROP-D, SPECTRUM, FRONTLINE, FRONTLINE XL, or TROPHY or INFINITY): Fill tank one-half to three-quarters full with clean water and start agitating. If mixing with, REFINE SG, or REFINE EXTRA, add the, REFINE SG, or REFINE EXTRA to tank water now and agitate, mixing thoroughly. Add 1 package of Spray Water pH Adjuster per jug of AVERT Herbicide to your tank water and agitate until dissolved. Add AVERT Herbicide first to the partially filled tank while agitating. If using CORDON or PUMA 120 SUPER, or one of the following: MCPA Ester, 2,4-D Ester, ATTAIN, ESTAPROP Plus, ESTAPROP XT, TURBOPROP, Dichlorprop-D, CURTAIL M, PRESTIGE, SPECTRUM, FRONTLINE, FRONTLINE XL or TROPHY or INFINITY in the tankmix, add now when tank is three-quarters filled while agitating. Fill tank and agitate, or, recycle for at least five minutes before spraying to ensure thorough mixing. 
Continue agitation until spraying is completed.

MIXING NOTE: 
AVERT Herbicide and the dry flowable herbicides, REFINE EXTRA, OR REFINE SG. When tank-mixing one of the above dry flowable herbicides with AVERT Herbicide, make sure the dry flowable is thoroughly dissolved in the water before adding AVERT Herbicide. On repeated tank-loads, if any tank-mix solution remains in the tank, prepare a dry flowable/water slurry and add it to the required water volume in the spray tank prior to adding AVERT Herbicide.

SPRAYER INFORMATION: 
Flat fan spray tips are recommended. Pressure at nozzle tips should be 275 kPa, lower pressures may result in poor control. Wash sprayer after spraying.

FOLLOW CROP RESTRICTIONS: 
The year following application of AVERT Herbicide, plant only these crops:
Brown and Dark Brown Soils: Spring Wheat, Durum Wheat, Barley, Sunflower, Canola – imazethapyr tolerant canola varieties only
Black and Grey Wooded Soils: Spring Wheat, Durum Wheat, Barley, Sunflower, Flax, Peas, Canola (all varieties) (1)
(1) If there has been below average rainfall in the year of the AVERT Herbicide treatment, and other imidazolinone herbicides (for example, Pursuit, Odyssey, Solo, etc) or soil residual sulfonylurea herbicides (for example, Ally) have been applied in the year preceding the AVERT Herbicide application, plant only imazethapyr tolerant canola (for example CLEARFIELD canola).
Two years following application of Avert Herbicide: Spring wheat,Durum wheat, Barley, Sunflowers, Peas, Flax, Oats, Canary grass, Canola
A field bioassay (a test strip grown to maturity) the year before planting any crop should be conducted for any crop not listed above. Lentils and sugarbeets have been observed to be particularly sensitive to AVERT Herbicide residues in the soil: The additive effect of soil residues from the use of AVERT Herbicide and other soil residual herbicides 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, particularly under conditions of below average rainfall. Wherever land will be treated with AVERT Herbicide and has been or will be treated with other imidazolinone herbicides (for example, Pursuit, Odyssey, Solo, etc) or soil residual sulfonylurea herbicides (for example, Ally) or Group 4 herbicides belonging to the pyridine carboxylic acid subgroup (for example, Curtail M, Prestige, etc.) plant only wheat (excluding durum) after both herbicides have been used until a bioassay demonstrates that other crops can be successfully grown. Consult the label of other imidazolinone herbicides (for example, Pursuit, Odyssey, Solo, etc) or soil residual sulfonylurea herbicides (for example, Ally) for additional information regarding bioassays.

DIRECTIONS FOR USE IN CEREALS: 
PRAIRIE PROVINCES and PEACE RIVER REGION OF BRITISH COLUMBIA ONLY
AVERT Herbicide, a selective postemergence herbicide for use in cereals, is absorbed through the foliage and roots of wild oat plants and other susceptible weeds. 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.

WILD OAT CONTROL 
AVERT Herbicide used alone and in combination should only be applied when the majority of WILD OAT plants are at the 1 - 4 leaf stage of growth.

BROADLEAF WEED CONTROL 
AVERT Herbicide used alone and applied at the cotyledon to six (6) leaf stage of weed growth will control: Wild mustard, Stinkweed
AVERT Herbicide used alone and applied at the cotyledon to four (4) leaf stage of weed growth provides partial control and reduces competition from: Wild buckwheat, Tartary buckwheat, Volunteer canola (EXCEPT imazethapyr tolerant varieties, i.e., varieties with the SMART trait.)

CROPS 
AVERT Herbicide may be used either alone or in tank-mix combinations on: Spring wheat, durum wheat. Spring barley. AVERT Herbicide may cause initial yellowing and temporary stunting on durum wheat but the crop will recover under normal growing conditions and yield will not be affected. Application can be made up to and including the 6-leaf stage of the crop (before the flag leaf).

RATES
GROUND APPLICATION:
Spring wheat, durum wheat and spring barley 1 to 4 leaf stage of wild oats: Apply 1.3 litres of AVERT Herbicide (400 g active) in 50 - 100 litres spray per hectare if majority of wild oats are in the 1-3 leaf stage. Use 1.6 litres of AVERT Herbicide (500 g active) if wild oats are in 4 leaf stage.

TANK-MIXES: 
Spring wheat, durum wheat and spring barley For fields which contain weeds other than those listed under AVERT Herbicide alone, tankmixing may be required to provide broad spectrum weed control. Use ONLY those broadleaf herbicides listed below. Tank mixes with chemical additives, pesticides or fertilizers not listed on this label may be physically incompatible, may cause unacceptable crop effects or may result in unacceptable weed or pest control. Contact Nufarm Agriculture Inc. at 1-800-868-5444 for more information. In order to ensure optimum herbicide broadleaf weed control, follow the label recommendations of the herbicide to be used with AVERT Herbicide. Follow the most restrictive precautions, directions, and recropping/rotation limitations that appear on both product labels. Select the proper AVERT Herbicide application rate given on this label.

DIRECTIONS FOR USE IN SUNFLOWERS: 
(PRAIRIE PROVINCES ONLY) AVERT Herbicide, a selective postemergence herbicide for use in sunflowers is absorbed through the foliage and roots of wild mustard and stinkweed 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.

WILD MUSTARD AND STINKWEED CONTROL 
Apply AVERT Herbicide alone at the cotyledon to 6 leaf stage of growth of wild mustard or stinkweed.

CROP 
AVERT Herbicide can be applied to sunflowers not under drought stress, from the 2 - 8 leaf stage of growth (sunflowers must be less than 38 cm high for regular varieties and less than 30 cm high for semi-dwarf varieties, and less than 10 cm for dwarf varieties). Crop injury in the form of head deformation and stunting can occur from applications made after the 8 leaf stage. RATES AVERT Herbicide should be applied at 0.85 litres of product (250 grams active) in 100 litres spray per hectare when the sunflowers are in the 2 - 8 leaf stage.
DIRECTIONS FOR USE IN ANNUAL RYEGRASS GROWN FOR SEED: 
AVERT Herbicide can be applied to annual ryegrass grown for seed, from the 4 to 6 leaf stage of the crop.

RATES 
AVERT Herbicide should be applied at 1.3 to 1.6 L/ha (390 to 480 g a.i./ha) in 100 litres of spray solution per hectare. Only one application of AVERT Herbicide to annual ryegrass grown for seed is permitted per year. Do not use the seed or hay for feed or forage.

RESISTANCE-MANAGEMENT RECOMMENDATIONS 
For resistance management, AVERT Herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to AVERT Herbicide and other Group 2 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance management strategies should be followed. To delay herbicide resistance:
Where possible, rotate the use of AVERT Herbicide or other Group 2 herbicides with different herbicide groups that control the same weeds in a field.
Use tank mixtures with herbicides from a different group when such use is permitted.
Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
Monitor treated weed populations for resistance development.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
