(1) DUAL II MAGNUM Herbicide contains benoxacor which has been shown to enhance S-Metolachlor metabolism in corn. This enhanced metabolism can reduce the potential of S-Metolachlor injury to corn seedlings when grown under unfavourable weather conditions such as cool temperature or water stress. Use of DUAL II MAGNUM Herbicide will not provide improved crop safety on other labelled crops.

Weeds controlled:
American Nightshade (1)
Fall Panicum
Eastern Black Nightshade (1)
Foxtail (green, yellow, giant)
Crabgrass (smooth, hairy)
Old Witchgrass
Barnyard Grass
Yellow Nutsedge (2)
Redroot Pigweed (3) (suppression only)

(1) Pre-emergent treatments sometimes give better control than pre-plant surface, pre-plant incorporated or post-emergent treatments.
(2) Pre-plant incorporated treatment only. Extended periods of dry hot weather following application may result in reduced nutsedge control.
(3) Pre-plant incorporated and pre-emergent treatments only.

As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

TIMING OF APPLICATION:
Eastern Canada: Pre-plant Surface or Pre-plant Incorporated or Pre-emergent or Early Post-emergent;
Prairies and Interior B. C.: Pre-plant Incorporated or Pre-emergent if irrigated within 10 days;
Coastal B. C.: Pre-emergent.

APPLICATION INFORMATION
DO NOT APPLY BY AIR.

PRE-PLANT SURFACE APPLICATION:
For minimum tillage (reduced tillage), and no-till (zero-till) systems in corn and soybeans. Do not use for soybean, immature seed.
Applications may be made up to 30 days before planting.
To the extent possible, do not move treated soil out of the row or move untreated soil to the surface during planting, or weed control will be diminished.

PRE-PLANT INCORPORATION:
Immediate incorporation is not necessary.
Incorporation equipment should include rolling or western harrows.
On sandy soils, heavy rainfall following an incorporated treatment may cause leaching of the herbicide.

Incorporation instructions:
Type of equipment / Maximum working depth / Minimum speed
"S"-Tine (Danish) cultivator / 10 cm / 10 km/hr
"C"-Tine cultivator with overlapping sweeps / 10 cm / 10 km/hr
Tandem disc (maximum 18 cm spacing between discs) / 10 cm / 6 km/hr
Power driven cultivator / 5 cm / any
Mulch Master / 5 cm / 10 km/hr

DUAL II MAGNUM Herbicide may be applied as an overall spray or as a band treatment. For band treatment, a suitable press wheel mounted ahead of the nozzle should be used for levelling the band. For
band application, use proportionately less material.

PRE-EMERGENT APPLICATION:
Apply evenly to a firm, lump-free seed bed.
Rain is required within 10 days or a shallow cultivation or use of a rotary hoe is necessary.
Pre-emergent applications may also be made in reduced tillage, ridge tillage, and no-till systems in corn and soybeans.
Minimize exposure of untreated soil when cultivating or fertilizing.

POST-EMERGENT APPLICATION:
CORN ONLY.
Apply when corn is in the spike to 6-leaf stage and before weeds pass the 2-leaf stage.
Some leaf burn may occur but yield will not be affected.
DO NOT tank-mix DUAL II MAGNUM Herbicide with fluid fertilizers, oils, oil concentrates or surfactants when applying post-emergent.
Do not graze treated immature crops or cut for hay. Do not harvest sweet corn within 45 days of application. Do not harvest other corn within 80 days of making a post-emergent application.
CAUTION:
Do not apply to soils that contain less than 1% or more than 10% organic matter. Winter cereals may be planted 4 1/2 months following application. If drought conditions persist after either a pre-plant surface, pre-plant incorporated or pre-emergent application, annual grass control may not be adequate.

LIQUID FERTILIZERS:
Nitrogen solutions or complete liquid fertilizers may replace water as a carrier for pre-plant surface, pre-plant incorporated or pre-emergent application of DUAL II MAGNUM Herbicide alone or in tank mixes in corn. Do not use fertilizer solutions for post-emergent applications. Always predetermine the compatibility of DUAL II MAGNUM Herbicide or labelled DUAL II MAGNUM Herbicide tank mixes with your water or liquid fertilizer carrier by mixing small proportional quantities in advance. Always consult the label of the tank mix partner if tank mixtures are to use liquid fertilizer as the carrier.

DRY BULK GRANULAR FERTILIZERS:
Many dry bulk granular fertilizers may be impregnated with DUAL II MAGNUM Herbicide plus AATREXherbicide for pre-plant incorporated application to control weeds in corn. Prepare the herbicide/fertilizer mixtures by using any commonly used dry bulk fertilizer blender. Spray herbicide mixture uniformly onto fertilizer. If the herbicide/fertilizer mixture is too wet, the use of a highly absorptive powder (generally less than 2% by weight) such as Microcel E, diatomaceous earth or finely powdered clay is recommended.
For best results, apply DUAL II MAGNUM Herbicide/fertilizer mixtures or DUAL II MAGNUM Herbicide plus AATREX herbicide/fertilizer mixtures uniformly to the soil with properly calibrated equipment immediately after blending and incorporate according to label directions.
Note: Apply a minimum of 225 kg per hectare of dry granular fertilizer impregnated with recommended rates of DUAL II MAGNUM Herbicide alone or DUAL II MAGNUM Herbicide tank mixtures.
Do not impregnate DUAL II MAGNUM Herbicide alone or with AATREX herbicide onto nitrate fertilizers, superphosphates, or limestone.

MIXING AND SPRAYING INSTRUCTIONS:
Spray Pressure - 200 - 300 kPa
Spray Volume - minimum 150 litres per hectare. The use of higher water volumes and larger spray tip sizes will generally increase spray deposition and reduce drift.
Keep bypass line at bottom of tank to minimize foaming.
Use 16 mesh suction screens, 50 mesh line and tip screens.
1. Fill sprayer 1/2 full of carrier. Start gentle agitation.
2. Add wettable powder or wettable granule tank-mix partner, if applicable. Slurry with water first if using liquid fertilizers as the carrier.
3. Add liquid flowable tank-mix partner, if applicable, and agitate thoroughly.
4. Fill tank 9/10 full of carrier and add DUAL II MAGNUM Herbicide and other emulsifiable concentrate or solution tank-mix partners.
5. Top off tank with carrier, maintain agitation and spray.
6. Do not let stand without agitation.
7. Sprayer equipment should be thoroughly flushed with clean water and drained before and after use of DUAL II MAGNUM Herbicide and its tank mixes.
Note: If using Fieldstar herbicide ensure that the water soluble packets and the Fieldstar herbicide are completely dissolved before proceeding to the next step.

STRAWBERRIES
Strawberry cultivars may vary in their tolerance to herbicides, including DUAL II Magnum Herbicide. Since not all strawberry cultivars have been tested for tolerance to DUAL II Magnum Herbicide, first use of DUAL II Magnum Herbicide should be limited to a small area of each variety to confirm tolerance prior to adoption as a general field practice. Additionally, consult your supplier for information on the tolerance of specific cultivars of strawberry to DUAL II Magnum Herbicide. Do not apply to the cultivar Joliette.

Weeds controlled –Control of nightshade and annual grasses and suppression of redroot pigweed
Rate / Ha DUAL II MAGNUM Herbicide - Banded to row middles after plastic mulch has been laid: 1.15 L/ha – 1.56 L/ha. Broadcast: 1.15 L/ha
Remarks - Ground application; Banded to row middles or broadcast. Make only 1 application per year. PHI is 30 days. Apply in a minimum of 150 L water/ha. Application of DUAL II MAGNUM Herbicide may result in injury to the crop which may include stand loss, delayed maturity and even loss of yield. Risk of crop injury increases with cool and wet conditions. Care should be taken to minimize foliar contact with DUAL II MAGNUM Herbicide as this can increase potential to cause crop injury. Avoid overspray. Reduced control in heavy weed populations may occur.

ENVIRONMENTAL HAZARDS
To reduce runoff from treated areas into aquatic habitats avoid application to areas with a moderate to steep slope, compacted soil, or clay.
Avoid application when heavy rain is forecast.
Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip between the treated area and the edge of the water body. For the protection of aquatic plants, overspray or drift to important wildlife habitats such as wetlands, sloughs or dry slough borders and water bodies should be avoided. Leave a buffer zone of 29 metres between the last spray swath and the edge of any of these habitats. Drift to emerging vegetation or newly emerged vegetation in shelterbelts or woodlots should be avoided. For tank mixes, consult the label(s) of the tank mix partner(s), and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.
This product contains a petroleum distillate which is moderately to highly toxic to aquatic organisms. Avoid contamination of aquatic systems during application. Do not contaminate these systems through direct application, disposal of waste or cleaning equipment.
CAUTION: 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. Do not harvest sweet corn within 45 days of application. Do not harvest other corn within 80 days of application. Make only one application per season.
When applied as a tank mix combination, read and observe all label directions, including rates, restrictions, and grazing limitations for each product used in the tank mix. Follow the more stringent label precautionary measures for mixing, loading and applying stated on both product labels.
DO NOT APPLY BY AIR.

Resistance-Management Recommendations 
For resistance management, DUAL II MAGNUM Herbicide is a Group 15 herbicide. Any weed population may contain or develop plants naturally resistant to DUAL II MAGNUM Herbicide and other Group 15 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 DUAL II MAGNUM Herbicide or other Group 15 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.
