MIXING NOTE: 
ASSERT 300 SC Herbicide and the dry flowable herbicides, REFINE EXTRA, REFINE SG, or EXPRESS PACK When tank-mixing one of the above dry flowable herbicides with ASSERT 300 SC Herbicide, make sure the dry flowable is thoroughly dissolved in the water before adding ASSERT 300 SC 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 ASSERT 300 SC 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.

DIRECTIONS FOR USE IN CEREALS: 
PRAIRIE PROVINCES and PEACE RIVER REGION OF BRITISH COLUMBIA ONLY 
ASSERT 300 SC 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 
ASSERT 300 SC 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 
ASSERT 300 SC Herbicide used alone and applied at the cotyledon to six (6) leaf stage of weed growth will control: Wild mustard Stinkweed ASSERT 300 SC Herbicide used alone and applied at the cotyledon to four (4) leaf stage of weed growth provides partial control of and reduces competition from: Wild buckwheat Tartary buckwheat Volunteer canola (EXCEPT imazethapyr tolerant varieties, i.e., varieties with the SMART trait.)
CROPS 
ASSERT 300 SC Herbicide may be used either alone or in tank-mix combinations on: Spring wheat, durum wheat. Spring barley. ASSERT 300 SC 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 ASSERT 300 SC Herbicide in 50 - 100 litres spray per hectare if majority of wild oats are in the 1-3 leaf stage. Use 1.6 litres of ASSERT 300 SC Herbicide if wild oats are in 4 leaf stage.
TANK-MIXES: 
In some cases, tank mixing a pest control product with another pest control product or a fertilizer can result in biological effects that could include, but are not limited to: reduced pest efficacy or increased host crop injury. The user should contact Nufarm Agriculture Inc. at 1-800-868-5444 for information before mixing any pesticide or fertilizer that is not specifically recommended on this label. The user assumes the risk of losses that result from the use of tank mixes that do not appear on this label or that are not specifically recommended by Nufarm Agriculture Inc. 
Spring wheat, durum wheat and spring barley
For fields which contain weeds other than those listed under ASSERT 300 SC 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 ASSERT 300 SC Herbicide. Follow the most restrictive precautions, directions, and recropping/rotation limitations that appear on both product labels.

DIRECTIONS FOR USE IN SUNFLOWERS: 
(PRAIRIE PROVINCES ONLY)
ASSERT 300 SC 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 ASSERT 300 SC Herbicide alone at the cotyledon to 6 leaf stage of growth of wild mustard or stinkweed.
CROP 
ASSERT 300 SC 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 
ASSERT 300 SC Herbicide should be applied at 0.85 litres of product 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: 
ASSERT 300 SC Herbicide can be applied to annual ryegrass grown for seed, from the 4 to 6 leaf stage of the crop.
RATES 
ASSERT 300 SC Herbicide should be applied at 1.3 to 1.6 L/ha in 100 litres of spray solution per hectare. Only one application of ASSERT 300 SC 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, please note that ASSERT 300 SC Herbicide is a Group 2 herbicide. Any weed population may contain plants naturally resistant to ASSERT 300 SC Herbicide and 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 ASSERT 300 SC Herbicide or other Group 2 herbicides within a growing season (sequence) or among growing seasons 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. To delay resistance, the less resistance-prone partner should control the target weed(s) as effectively as the more resistance-prone partner.
Herbicide use should be based on an integrated weed management program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical control methods), cultural (for example, higher crop seeding rates; precision fertilizer application method and timing to favour the crop and not the weeds), biological (weed-competitive crops or varieties) and other management practices.
Monitor weed populations after herbicide application for signs of resistance development (for example, only one weed species on the herbicide label not controlled). If resistance is suspected, prevent weed seed production in the affected area if possible by an alternative herbicide from a different group. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.
Have suspected resistant weed seeds tested by a qualified laboratory to confirm resistance and identify alternative herbicide options.
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.
