GF-1352

GENERAL INFORMATION
GF-1352 Herbicide is a selective herbicide for postemergent control of hard-to-kill annual broadleaf weeds such as chickweed, wild buckwheat, and cleavers in spring wheat (including durum), spring barley and winter wheat not underseeded with legumes.
GF-1352 Herbicide, alone or in tank-mix with glyphosate herbicides, controls weeds prior to seeding spring wheat (including durum), spring barley, winter wheat and oats. GF-1352 Herbicide can be applied in the fall or spring prior to planting or as an initial treatment in summerfallow.
GF-1352 Herbicide is a dispersible granule that is mixed with water and applied as a uniform broadcast spray. It is non-corrosive, nonflammable, and nonvolatile.
GF-1352 Herbicide must be applied early postemergence to the main flush of actively growing broadleaf weeds. Warm, moist growing conditions promote active weed growth and enhance the activity of
GF-1352 Herbicide by allowing maximum foliar uptake and contact activity. Weeds hardened off by cold weather or drought stress may not be adequately controlled or suppressed and re-growth may occur. For best results, ensure thorough spray coverage of target weeds. See DIRECTIONS FOR USE section of this label for complete use details.
GF-1352 Herbicide stops growth of susceptible weeds rapidly. However, typical symptoms (discolouration) of dying weeds may not be noticeable for 1 to 2 weeks after application, depending upon growing conditions and weed susceptibility. Degree of control and duration of effect are dependent on weed sensitivity, weed size, crop competition, growing conditions at and following treatment, and spray coverage.

MODE OF ACTION
GF-1352 Herbicide inhibits the production of the ALS enzyme in plants. This enzyme is essential for the production of certain amino acids which are essential for plant growth. GF-1352 Herbicide is a Group 2 mode of action herbicide.

GENERAL USE PRECAUTIONS
DO NOT APPLY BY AIR.
Do not use in successive years at the same site.
This product has potential to leach. Do not apply excessive irrigation.
Do not apply through any type of irrigation system.

Sensitive Plants
Do not apply GF-1352 Herbicide directly to, or otherwise permit it to come in direct contact with susceptible crops or desirable plants including alfalfa, edible beans, canola, flowers and ornamentals, lentils, lettuce, peas, potatoes, radishes, soybeans, sugar beets, sunflowers, tomatoes or tobacco.

Non-Target Sites
Do not apply where proximity of susceptible crops (e.g. canola and legumes) or other desirable plants is likely to result in exposure to spray or spray drift. See Environmental Hazards section of the label.

Crop Rotation
Fields previously treated with GF-1352 Herbicide can be seeded the following year to barley, canola, chickpeas, corn, field beans, flax, Juncea canola, lentils, mustard (brown, yellow and/or oriental), oats, peas, potatoes (except seed potatoes), soybeans, sunflower, wheat, or fields can be summerfallowed. Do not use in successive years at the same site.

Preharvest/Grazing Intervals
Livestock may be grazed on treated crops 7 days following application. Do not harvest the treated crop within 60 days after application.

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.

To Reduce Spray Drift
1. Use nozzles delivering higher volumes and coarser droplets.
2. Use low pressures (200 to 275 kPa).
3. Use 100 L/ha of spray solution.
4. Spray when the wind velocity is 15 km/hr or less.
5. Spot treatments should only be applied with a calibrated boom to prevent over-application.

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.

DIRECTIONS FOR USE

READ THE ENTIRE LABEL BEFORE USE. FAILURE TO FOLLOW LABEL INSTRUCTIONS MAY RESULT IN ERRATIC WEED CONTROL OR CROP DAMAGE. DO NOT APPLY TO CROPS UNDERSEEDED WITH LEGUMES.

IN-CROP USE - GF-1352 HERBICIDE ALONE

Crops Registered
spring wheat (including durum), winter wheat and spring barley

Application Directions
Apply 20 grams of GF-1352 Herbicide per hectare in a minimum of 100 L per hectare of water. Add Agral 90 at 0.2% v/v. See weeds species controlled under “Weeds Controlled or Suppressed by GF-1352 Herbicide Alone at 20 g/ha”. Apply to actively growing wheat and barley from the 2 to 6 leaf stage.

TANK-MIX COMBINATIONS OF GF-1352 HERBICIDE + GLYPHOSATE HERBICIDES
GF-1352 Herbicide + glyphosate herbicides (PRESENT AS ISOPROPYLAMINE SALT, DIAMMONIUM SALT, TRIMETHYLSULFONIUM SALT, POTASSIUM SALT OR DIMETHYLAMINE SALT) will control annual broadleaved weeds and grasses when applied in the fall or spring prior to planting spring wheat (including durum), winter wheat, barley and oats, or as an initial treatment in summerfallow.
GF-1352 Herbicide + glyphosate must be applied to emerged actively growing weeds. Warm, moist growing conditions promote active weed growth and enhance the activity of GF-1352 Herbicide + glyphosate herbicides by allowing maximum foliar uptake and contact activity. Weeds hardened off by cold weather or drought stress may not be adequately controlled or suppressed and re-growth may occur. For best results, ensure thorough spray coverage of target weeds.
GF-1352 Herbicide + glyphosate stops growth of susceptible weeds rapidly. However, typical symptoms (discolouration) of dying weeds may not be noticeable for 1 to 2 weeks after application, depending upon growing conditions and weed susceptibility. Degree of control and duration of effect are dependent on weed sensitivity, weed size, crop competition, growing conditions at and following treatment, and spray coverage.
Delay application until weeds have emerged to the stages described (see “Weeds Controlled or Suppressed by GF-1352 Herbicide + glyphosate”) to provide adequate leaf surface to receive the spray. Unemerged weeds or vegetation arising from underground rhizomes or root stocks of perennials will not be affected by the spray and will continue to grow. For this reason, best control of most perennial weeds is obtained when treatment is made at late growth stages approaching maturity.
Do not treat weeds under poor growing conditions such a drought stress, disease or insect damage, as reduced weed control may result. Reduced results may also occur when treating weeds heavily covered with dust.
This product does not provide long-term residual weed control. For subsequent residual weed control, follow a label approved herbicide program. Read and carefully observe the cautionary statement and all other information appearing on the labels of all herbicides used.
Heavy rainfall immediately after application may wash the chemical off the foliage and a repeat treatment may be required. Do not apply if rainfall is forecast for the time of application.
Do not mix with any surfactant, pesticide, herbicide oil or any other material other than water unless specified in this booklet. For best results, spray coverage should be uniform and complete. Do not spray weed foliage to the point of runoff.

Mode of Action
This herbicide tank-mix moves through the plant from the point of foliage contact to and into the root system. Visible effects on most annual weeds occur within 2 to 4 days but on most perennial weeds may not occur until 7 to 10 days. Extremely cool or cloudy weather at treatment time may slow down activity of this product and delay visual effects of control. Visible effects are a gradual wilting and yellowing of the plant which advances to complete browning of above ground growth and deterioration of underground plant parts.

ATTENTION: AVOID CONTACT WITH FOLIAGE, GREEN STEMS, OR FRUIT OF CROPS, DESIRABLE PLANTS AND TREES SINCE SEVERE INJURY OR DESTRUCTION MAY RESULT.

APPLY THESE SPRAY SOLUTIONS IN PROPERLY MAINTAINED AND CALIBRATED EQUIPMENT CAPABLE OF DELIVERING DESIRED VOLUMES.

AVOID DRIFT - EXTREME CARE MUST BE USED WHEN APPLYING THIS PRODUCT TO PREVENT INJURING DESIRABLE PLANTS AND CROPS. Do not allow spray mist to drift since even minute quantities of spray can cause severe damage or destruction to nearby crops, plants or other areas on which treatment is not intended, or may cause other unintended consequences. Do not apply when winds are gusty or in excess of 8 km/h or when other conditions, including lesser wind velocities, will allow drift to occur. When spraying, avoid combinations of pressure and nozzle type that will result in fine particles (mist) which are more likely to drift.
DO NOT USE IN GREENHOUSES. REDUCED RESULTS MAY OCCUR IF WATER CONTAINING SOIL IS USED, SUCH AS WATER FROM PONDS AND UNLINED DITCHES.

Application Directions
GF-1352 Herbicide can be tank mixed with glyphosate herbicides (present as isopropylamine salt, diammonium salt, trimethylsulfonium salt, potassium salt or dimethylamine salt) to broaden the spectrum of broadleaf weeds. These tank mixes will provide control of most grass and broadleaf species.

GF-1352 Herbicide + Glyphosate Herbicides
(present as isopropylamine salt, diammonium salt, trimethylsulfonium salt, potassium salt or dimethylamine salt)
Apply 450 - 2500 grams a.e. per hectare of glyphosate herbicide (present as isopropylamine salt, diammonium salt, trimethylsulfonium salt, potassium salt or dimethylamine salt) tank mixed with 20 g of GF-1352 Herbicide per hectare.
Always refer to the product label for the tank-mix partner for further information on weeds controlled, directions for use, restrictions and precautionary label statements. When applied as a tank-mix, consult the labels of the tank-mix partners and observe the most restrictive buffer zone of the products involved in the tank mixture.

Application Timing
Apply to actively growing weeds in the 2-4 leaf stage, except where noted above. Extreme growing conditions such as drought or near freezing temperature prior to, at or following time of application may reduce weed control. Only weeds which are emerged at the time of application will be affected. If foliage is wet at the time of application, control may be decreased. Under conditions of high weed density, control may be reduced.

Pre-Seed (spring or fall)
GF-1352 Herbicide + glyphosate may be applied prior to seeding and no longer than 48 hours after seeding prior to any crop emergence. Fields treated with GF-1352 Herbicide + glyphosate may be planted to barley, oats, spring wheat (including durum), winter wheat or summerfallowed.

Chem-Fallow
May 1 to July 31: GF-1352 Herbicide may be applied to summerfallow fields and seeded in the fall to winter wheat and in the following spring to barley, canola, oats, peas or wheat (including durum) or summerfallowed.

Fall Application
GF-1352 Herbicide plus glyphosate may be applied to stubble or summerfallow fields after August 1st and prior to freeze-up and may be seeded in the fall to winter wheat and in the following spring to barley, oats or spring wheat (including durum) or summerfallowed.

Heavy rainfall immediately after application may wash the chemical off the foliage and a repeat treatment may be required. Do not apply if rainfall is forecast for the time of application.
Do not mix with any surfactant, pesticide, herbicide oil or any other material other than water unless specified in this booklet. For best results, spray coverage should be uniform and complete. Do not spray weed foliage to the point of runoff.

Mode of Action
This herbicide tank-mix moves through the plant from the point of foliage contact to and into the root system. Visible effects on most annual weeds occur within 2 to 4 days but on most perennial weeds may not occur until 7 to 10 days. Extremely cool or cloudy weather at treatment time may slow down activity of this product and delay visual effects of control. Visible effects are a gradual wilting and yellowing of the plant which advances to complete browning of above ground growth and deterioration of underground plant parts.

ATTENTION: AVOID CONTACT WITH FOLIAGE, GREEN STEMS, OR FRUIT OF CROPS, DESIRABLE PLANTS AND TREES SINCE SEVERE INJURY OR DESTRUCTION MAY RESULT.

APPLY THESE SPRAY SOLUTIONS IN PROPERLY MAINTAINED AND CALIBRATED EQUIPMENT CAPABLE OF DELIVERING DESIRED VOLUMES.

AVOID DRIFT - EXTREME CARE MUST BE USED WHEN APPLYING THIS PRODUCT TO PREVENT INJURING DESIRABLE PLANTS AND CROPS. Do not allow spray mist to drift since even minute quantities of spray can cause severe damage or destruction to nearby crops, plants or other areas on which treatment is not intended, or may cause other unintended consequences. Do not apply when winds are gusty or in excess of 8 km/h or when other conditions, including lesser wind velocities, will allow drift to occur. When spraying, avoid combinations of pressure and nozzle type that will result in fine particles (mist) which are more likely to drift.
DO NOT USE IN GREENHOUSES. REDUCED RESULTS MAY OCCUR IF WATER CONTAINING SOIL IS USED, SUCH AS WATER FROM PONDS AND UNLINED DITCHES.

Application Directions
GF-1352 Herbicide combined with Dicamba and glyphosate herbicides (present as isopropylamine salt, diammonium salt, trimethylsulfonium salt, potassium salt or dimethylamine salt) can be tank mixed to broaden the spectrum of broadleaf weeds. These tank mixes will provide control of most grass and broadleaf species.

GF-1352 Herbicide + Dicamba + Glyphosate Herbicides
(present as isopropylamine salt, diammonium salt, trimethylsulfonium salt, potassium salt or dimethylamine salt)
Apply 450-2500 grams a.e. per hectare of glyphosate herbicide (present as isopropylamine salt, diammonium salt, trimethylsulfonium salt, potassium salt or dimethylamine salt) tank mixed with 20 g of GF-1352 Herbicide and 115-120 g a.e ha Dicamba herbicide per hectare.
Always refer to the product label of the tank-mix partner for further information on weeds controlled, directions for use, restrictions and precautionary label statements. When applied as a tank-mix, consult the labels of the tank-mix partners and observe the most restrictive buffer zone of the products involved in the tank mixture.

Mixing Instructions
1. Fill sprayer tank 1/2 full of water.
2. Start sprayer tank agitation.
3. Add the required amount of GF-1352 Herbicide, continue agitation.
4. Add the required amount of Dicamba, continue agitation.
5. Add the required amount of glyphosate, continue agitation.
6. Fill the sprayer tank with sufficient water to spray 50 - 100 L of spray mixture per hectare.

Application Timing
Apply to actively growing weeds in the 2-4 leaf stage, except where noted above. Extreme growing conditions such as drought or near freezing temperature prior to, at or following time of application may reduce weed control. Only weeds which are emerged at the time of application will be affected. If foliage is wet at the time of application, control may be decreased. Under conditions of high weed density, control may be reduced.

Pre-Seed (spring or fall)
GF-1352 Herbicide + dicamba + glyphosate may be applied prior to seeding and no longer than 48 hours after seeding prior to any crop emergence. Fields treated with GF-1352 Herbicide + dicamba + glyphosate may be planted to barley, oats, spring wheat (including durum), winter wheat or summerfallowed.

Chem-Fallow
May 1 to July 31: GF-1352 Herbicide + dicamba + glyphosate may be applied to summerfallow fields and seeded in the fall to winter wheat, and in the following spring to spring wheat (including durum), barley and oats.
Do not use in successive years at the same site.

RESISTANCE MANAGEMENT RECOMMENDATIONS
For resistance management, please note that GF-1352 Herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to GF-1352 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 GF-1352 Herbicide or other Group 2 herbicide 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.
