STORAGE
Store product in original container in a secure, dry area away from food or feed. Not for use or storage in or around the home. Keep container tightly closed. Keep water soluble bags in original outer bag away from moisture.

DISPOSAL
1. Triple-or pressure-rinse the empty container. Add the rinsings to the spray mixture in the tank.
2. Follow provincial instruction for any required additional cleaning of the container prior to its disposal.
3. Make the empty container unsuitable for further use.
4. Dispose of the empty container in accordance with provincial requirements.
5. For information on the disposal of unused, unwanted product, contact the manufacturer or the provincial regulatory agency. Contact the manufacturer and the provincial regulatory agency in case of a spill, and for clean up of spills.

GENERAL INFORMATION
CLASSIC 25 DF Herbicide is recommended for selective postemergence control of broadleaf weeds in soybeans. CLASSIC 25 DF Herbicide can also be applied pre plant or post plant preemergence to soybeans, either conventional or glyphosate tolerant. CLASSIC 25 DF Herbicide is formulated as a dry flowable granule to be mixed in water and applied as a uniform broadcast spray. It is noncorrosive, nonflammable, nonvolatile, and does not freeze. CLASSIC 25 DF Herbicide is pre-packaged in water soluble bags; each 36 g water soluble bag treats 1 hectare. Use gloves when handling the water soluble bags. Reseal unused water soluble bags away from excess moisture or physical damage during storage and prior to mixing in the spray tank. Do not reuse outer bag.
CLASSIC 25 DF Herbicide can be applied with a recommended surfactant either as a pre plant or post plant preemergence application to soybeans, either conventional or glyphosate tolerant or early postemergence to the main flush of actively growing weeds. Warm, moist growing conditions promote active weed growth and enhance the activity of CLASSIC 25 DF Herbicide by allowing maximum foliar uptake and contact activity. Weeds hardened off by environmental stress may not be adequately controlled and regrowth may occur. CLASSIC 25 DF Herbicide may only be applied using ground equipment. For best results, ensure thorough spray coverage of target weeds.
CLASSIC 25 DF Herbicide rapidly stops growth of susceptible weeds. However, typical symptoms (discoloration) of dying weeds may not be noticeable for 1 to 3 weeks after application, depending on growing conditions and weed susceptibility. Favourable growing conditions following treatment promote the activity of CLASSIC 25 DF Herbicide while cold, dry conditions delay the activity.
Degree of control and duration of effect depend on weed sensitivity, weed size, crop competition, growing conditions and spray coverage.

DIRECTIONS FOR USE
RATES AND TIMING
PRE EMERGENT:
For the season long control of dandelion (up to bolting) apply 36 g/ha of CLASSIC 25 DF HERBICIDE, plus Agral 90 at 0.2%v/v, pre plant or post plant pre-emergence to soybeans, either in conventional or glyphosate tolerant.
POSTEMERGENT APPICATION:
Optimum timing of CLASSIC 25 DF Herbicide for annual broadleaf weed control is when soybeans are in the 1 to 3 trifoliate stage of growth. Do not apply CLASSIC 25 DF Herbicide before the first trifoliate has fully expanded or after the initiation of flowering. CLASSIC 25 DF Herbicide can be applied up to 60 days before harvest.
One water soluble bag treats 1 hectare.
Use 36 grams of CLASSIC 25 DF Herbicide per hectare. A non-ionic surfactant such as AGRAL 90, CITOWETT PLUS, or AG-SURF must also be used at 0.2% v/v. OPTIONAL: The addition of liquid fertilizer containing 28% nitrogen to the spray mixture at the rate of 2 litres per hectare may improve control of velvetleaf and should be added after the surfactant.
For best results, apply to young actively growing weeds before the soybean canopy closes. Weeds that emerge after treatment may not be controlled.
NOTE: Do not apply to soybeans that have been stressed by severe weather conditions such as frost or hot, humid weather as crop injury may result.
If rain occurs after application, control may be reduced. Two - four hours of dry weather are needed to allow CLASSIC 25 DF Herbicide to be absorbed by weed foliage.

CLASSIC 25 DF HERBICIDE TANK MIXES
Apply CLASSIC 25 DF HERBICIDE at 36 grams per hectare, tank mixed with glyphosate (present as potassium salt, isopropylamine salt, or di-ammonium salt) and adjuvant (where required).
Consult the respective glyphosate herbicide labels for specific instructions for 'Directions for Use', Precautions, and for other weeds controlled by glyphosate herbicide.
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 E.I du Pont Canada Company at 1-800-667-3925 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 E.I du Pont Canada Company.
If rain occurs after application, control may be reduced. Two - four hours of dry weather are needed to allow CLASSIC 25 DF Herbicide to be absorbed by weed foliage.

MIXING INSTRUCTIONS
1. Fill clean tank about 1/4 full with fresh water.
2. Turn on full agitation.
3. Add the proper amount of CLASSIC 25 DF Herbicide to the water in the spray tank with the agitator running. Maintain full agitation until water-soluble bags are completely dissolved and product is fully dispersed. Continuous agitation is required to keep the product in suspension.
4. After CLASSIC 25 DF Herbicide has been well mixed and is in suspension, add the tank mix partner, if applicable.
5. Add a recommended amount of spray adjuvant (if required).
6. Fill the remainder of the spray tank with clean water.
On repeat tank loads, ensure that the amount of spray solution left in the tank from the previous load is less than 10% of the volume about to be mixed.
Agitation is required for uniform mixing and application. The optimum water volume for CLASSIC 25 DF Herbicide application is 140-190 litres of water per hectare (minimum of 100 litres of water per hectare). Flat fan nozzles are recommended. Use 50 mesh filter screens or larger. Use spray preparation of CLASSIC 25 DF Herbicide within 24 hours or product degradation may occur resulting in a loss of weed control. Use vigorous agitation to thoroughly disperse spray mixtures that have been allowed to stand in the tank.
NOTE: CLASSIC 25 DF Herbicide will degrade in acidic or highly alkaline water. Mix no more than can be used in one day. If spraying is interrupted, thoroughly re-agitate the spray mixture before resuming spraying.
NOTE: Do not mix the soluble bags with liquid fertilizers, substances that contain boron or substances that release free chlorine. Mixing the water soluble bags with any of these compounds will result in an insoluble substance in the tank.
Do not mix or load where there is potential to contaminate wells or aquatic systems.

REPLANTING TO OTHER CROPS
CLASSIC 25 DF Herbicide is degraded by natural soil processes, and field tes ts have shown that the following crops may safely be planted at the prescribed interval following soybeans that have been treated with CLASSIC 25 DF Herbicide. The recropping intervals are dependent on the pH of the soil, as well as the sensitivity of the specific rotational crop.
