DIRECTIONS FOR USE

USE PRECAUTIONS

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/drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
Apply only when the potential for drift to areas of human habitation or areas of human activity such as houses, cottages, schools and recreational areas is minimal. Take into consideration wind speed, wind direction, temperature inversions, application equipment and sprayer settings.

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 than the American Society of Agricultural Engineers (ASAE) coarse classification. Boom height must be 60 cm or less above the crop or ground.

Restricted Entry Interval (REI)
For scouting in soybeans, do not enter or allow worker re-entry until 48 hours after treatment.
For all other activities, do not enter or allow worker re-entry until 12 hours after treatment.

Ground Application - Cropland
Apply 50 to 200 L of spray solution per hectare depending on the type of application equipment used. Use sufficient water for even distribution. Spray at low pressures (200 to 275 kPa) when the weeds are actively growing.
Droplet Size: Apply as a coarse to extremely coarse spray (ASABE S-572 Standard). Use drift reducing nozzle tips in accordance with manufacturer directions that produce a droplet classification of coarse to extremely coarse to significantly reduce the potential for drift.
Refer to the Product Use Guide for further information.

To Prepare a Spray

Add half the required amount of water to the spray tank, then the GF-2726 TSOY Herbicide with agitation, and finally the balance of the water with continued agitation.

Spot Treatment

For knapsack application of GF-2726 TSOY Herbicide for spot treatment of weeds such as thistles, mix 0.2 L of product in 10 L of water. Wet all foliage thoroughly. Maximum 2 applications per year.
Maximum Amount of product applied/day/person with handheld equipment: 14.5 L.

Tank Mixtures

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 Dow AgroSciences Canada Inc at 1-800-667-3852 or www.dowagro.ca 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 Dow AgroSciences Canada Inc.

FOR USE IN ENLIST SOYBEAN

GF-2726 TSOY Herbicide is a systemic herbicide with very limited soil residual activity and is intended for control of emerged annual and perennial weeds. GF-2726 TSOY Herbicide is selective to Enlist soybeans. Enlist soybeans contain an AAD-12 expressing event plus a glyphosate tolerance trait. These are patented genes that provide tolerance to GF-2726 TSOY Herbicide. For non-Enlist soybeans not containing an expressing event plus glyphosate tolerance traits, foliar application of GF-2726 TSOY
Herbicide will cause serious crop damage and yield loss.

Rates of application
Use 2.9 – 4.3 L/ha depending on the weeds present (see weed list below).

Sprayer Clean-Out Instructions
To avoid injury to desirable plants, thoroughly clean equipment used to apply this product before re-use or using it to apply other chemicals.
1. Immediately after spraying, completely drain the sprayer tank. Any contamination on the outside of the spraying equipment should be removed by washing with clean water.
2. First rinse:
Spray the inside of tank with clean water and fill the sprayer with at least one tenth of the spray tank volume.
Agitate and circulate for 15 minutes, and flush through booms and hoses.
Remove end caps or open ball valves on the ends of each boom section, and flush solution through the boom ends to ensure there is no spray solution trapped between the boom end and the nozzles.
Drain tank completely.
3. Second rinse:
Fill the tank with clean water.
Add All Clear Spray Tank Decontaminator, or Clean-Out Spray Tank Cleaner, or 1 L of household ammonia (containing a minimum of 3 % ammonia) per 100 L of water, or similar tank cleaning agent as per manufacturer’s recommendations while filling the tank with clean water.
Agitate and then flush the boom and hoses with the cleaning solution. Top up with water making
sure the tank is completely full. Allow to stand for 15 minutes with agitation. Flush the solution out of the spray tank through the spray booms. Remove end caps or open ball valves on the ends of each boom section, and flush solution through the boom ends to ensure there is no spray solution trapped between the boom end and the nozzles.
If possible, let the solution stand in the sprayer tank and booms for an extended period of time, overnight if possible.
After flushing the boom and hoses, drain tank completely.
Remove nozzles and screens and clean separately with a cleaning agent or an ammonia solution (100 mL in 10 L water).
4. Third rinse:
Rinse the tank with clean water and flush through the boom and hoses using at least one tenth of the spray tank volume.
Remove end caps or open ball valves on the ends of each boom section, and flush solution through the boom ends to ensure there is no spray solution trapped between the boom end and the nozzles.
Drain tank completely.
Do not use ammonia with chlorine bleach. Using ammonia with chlorine bleach will release a gas with a musty odour which may cause eye, nose, throat and lung irritation. Do not clean equipment in an enclosed area.

Drift Control Additives
GF-2726 TSOY Herbicide contains drift control technology. If desired, use only a Dow AgroSciencesapproved drift control additive. When a drift control additive is used, read and carefully observe the precautionary statements and all other information appearing on the additive label.

Timing of Application
Apply when weeds are small and soybean growth stage is no later than R2 (full flowering stage). Make one to two applications with a minimum of 12 days between applications. Do not apply GF-2654 TSOY Herbicide to soybeans later than the R2 stage.

Pre-Harvest Interval
Do not graze treated soybeans.
Do not harvest for forage or hay.

Restrictions
Do not apply more than two post emergent applications per use season.
Do not apply more than 8.6 L/ha of GF-2726 TSOY Herbicide (3.44 kg acid equivalent) per use season.
Read and follow the DAS Stewardship Program (http://www.traitstewardship.com) that accompanies the use of soybean seed containing the DAS-68416-4 gene.

Sensitive Plants
Vegetables, flowers, grapes, fruit trees and other desirable plants are sensitive to 2,4-D, even in minute quantities. Care should be taken to avoid spraying these types of plants or allowing spray mist to drift onto these plants during both their growing and dormant periods. Coarse sprays are less likely to drift. At higher temperatures, vaporization may cause injury to susceptible plants growing nearby. This product may cause damage to lawns or pastures if applied before the grass is well established. In addition, most legumes may be damaged or killed.

FOR USE PRIOR TO SEEDING OR AFTER SEEDING (BUT BEFORE CROP EMERGENCE) IN SPRING AND WINTER VARIETIES OF WHEAT (INCLUDING DURUM), BARLEY AND RYE

GF-2726 TSOY Herbicide may be applied to control both annual and perennial weed species prior to seeding or after seeding (BUT BEFORE CROP EMERGENCE) in spring and winter varieties of wheat (including durum), barley and rye.
Apply at a rate of 2.2 L per hectare in a water volume of 50 to 100 L of clean water per hectare as a broadcast spray for control of weeds (up to 8 cm in height) or at a rate of 3.3 L per hectare for control of weeds (up to 15 cm in height)

BUFFER ZONES TO PROTECT SENSITIVE HABITATS
Buffer zones are not required for applications with handheld equipment and for spot treatment.
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 freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.
Seasonal water bodies require buffer zones if there is water in them during application. Water bodies which do not fill on an annual basis need not be buffered.
When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.

RESISTANCE MANAGEMENT RECOMMENDATIONS
For resistance management, GF-2726 TSOY Herbicide is both a Group 4 and a Group 9 herbicide. Any weed population may contain or develop plants naturally resistant to GF-2726 TSOY Herbicide and other Group 4 and Group 9 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 GF-2726 TSOY Herbicide or other Group 4 and 9 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 resistancemanagement and/or integrated weed-management recommendations for specific crops and weed biotypes.
For further information or to report suspected resistance, contact Dow AgroSciences Canada Inc. at 1- 800-667-3852 or at www.dowagro.ca.
