GENERAL INFORMATION

REGISTERED CROPS:
RESISTANCE-MANAGEMENT RECOMMENDATIONS
For resistance management, Trifluralin 10G is a Group 3 herbicide. Any weed population may contain or develop plants naturally resistant to Trifluralin 10G and other Group 3 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 Trifluralin 10G or other Group 3 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 resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
- For further information or to report suspected resistance, contact Makhteshim-Agan of North America Inc. at 1 919 256-9300.

TRIFLURALIN 10G is a selective herbicide for the control of certain annual grass and broadleaved weeds in Rapeseed (Canola),Barley (Fall Application Only), Flax (do not use on low linolenic acid varieties) (Summer and Fall Application Only), Sunflowers, Mustard, Peas (Field and Canning), Lentils (Fall Application Only), Fababeans and Triazine Tolerant Rapeseed (Canola).

DO NOT USE TRIFLURALIN 10G ON ANY CROP FOR WHICH IT IS NOT REGISTERED.
CAUTION: Do not graze the treated crops or cut for hay; there are not sufficient data available to support such use.
Carefully read all directions before applying TRIFLURALIN 10G.
FAILURE TO FOLLOW LABEL INSTRUCTIONS MAY RESULT IN ERRATIC WEED CONTROL OR CROP DAMAGE.

DIRECTIONS FOR USE IN ALL CROPS

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application.
Discard clothing or other absorbent materials that have been heavily contaminated with this product. DO NOT reuse them .
Users should remove clothing immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing.
DO NOT apply this product directly to freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs, ditches and wetlands), estuaries or marine habitats.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
To minimize the release of trifluralin into the environment due to volatilization, trifluralin should only be applied on cool mornings and evenings when air temperatures are 15°C or lower. To further reduce volatilization to the atmosphere, incorporation into
the soil should occur concurrently with application.
-Do not apply to soils which contain more than 15% organic matter such as peat or muck soils (maximum 10% organic matter on Barley).
-Do not apply to wet soils that are subject to flooding.
-Do not apply to soils that are extremely cloddy, lumpy or in poor working condition
-Follow label directions at all times for maximum weed control and crop tolerance. Read all directions before applying TRIFLURALIN 10G.

CAUTION
Populations of green foxtail tolerant to trifluralin have developed in a number of fields in Western Canada which have had a long history of repeated trifluralin use. Trifluralin- or ethalfluralin-containing products (i.e., HERITAGE, RIVAL, TREFLAN, TRIFLUREX, TRIFLURALIN, FORTRESS, and EDGE) will not control trifluralin tolerant green foxtail. To delay selection or reduce the spread of trifluralin tolerant green foxtail, avoid use of these products repeatedly in the same field, or use a separate herbicide application for control of trifluralin-tolerant green foxtail.
TRIFLURALIN 10G application to soils that are subject to flooding (standing water for more than 3-5 days) may result in reduced weed control. This reduction in weed control may occur if the soils are flooded between the time of application and crop maturity (harvest). No weed control at all may result if the soils are flooded for a considerable period of time (3 weeks or more).
TRIFLURALIN 10G will not damage the treated crop when used according to label directions. Factors such as deep planting, seedling disease, cold temperatures, excessive moisture, poor soil fertility, drought and saline soils may increase the risk of damage from TRIFLURALIN 10G resulting in delay in crop maturity and/or reduced yields.
The following highly sensitive crops should not be grown in rotation the year following TRIFLURALIN 10G application: tame oats, sugarbeets and small seeded annual grasses (Timothy, Canary Grass and Creeping Red Fescue).

SPECIAL INSTRUCTIONS FOR CROP ROTATIONS
-The breakdown rate of TRIFLURALIN 10G is influenced by environmental factors which occur during the year of control and those of the following spring; i.e., May 1-May 1. Below normal precipitation during this period will increase the level of carryover into the following growing season.
-Injury may result to rotational crops (e.g., wheat) if grown in the second year of a crop rotation following dry soil conditions during the first crop year after TRIFLURALIN 10G application. Seed the rotational crops shallowly into a warm, moist seedbed to reduce injury.

DIRECTIONS FOR USE IN OILSEED CROPS, BARLEY AND SPECIAL CROPS

SUSCEPTIBLE WEEDS:
ANNUAL GRASS WEEDS: Wild Oats, Green and Yellow Foxtail (Wild Millet), Barnyard Grass, Persian Darnel, Annual Bluegrass, Crabgrass, Stinkgrass, Bromegrass, Cheat and Goosegrass.
ANNUAL BROADLEAVED WEEDS: Pigweed, Russian Thistle, Lamb’s Quarters, Chickweed, Carpetweed, Knotweed, Purslane, Cow Cockle and Wild Buckwheat.
TRIFLURALIN 10G will control the above weeds when applied at recommended rates and used as directed. Ensure that all incorporation directions are followed. Crop competition will effectively suppress some wild oats and wild buckwheat which may escape the TRIFLURALIN 10G herbicidal action so that little or no competition results with the crop.

TIME OF APPLICATION
Apply TRIFLURALIN 10G before the crop is planted and before weed emergence. Thorough incorporation into the soil is needed to provide herbicidal action that will control all susceptible weeds.
TRIFLURALIN 10G does not control susceptible weeds that have already emerged through the soil at the time of application. It only controls susceptible weeds as they germinate.

LAND PREPARATION
Ensure that all emerged and existing weeds have been eliminated through discing, cultivation or by chemical control before applying TRIFLURALIN 10G. The granules can be applied to stubble or trashy soils. In order to allow product penetration into the soil surface, heavy trash soils should be thoroughly disced prior to TRIFLURALIN 10G application . All large soil clods should be broken up before TRIFLURALIN 10G application.

If manure has been applied to the field, ensure that it is thoroughly mixed into the soil with at least two tillage operations prior to TRIFLURALIN 10G application.
If the field has been burned in order to remove previous crop residue (straw, trash, etc.), ensure that the field is tilled at least once prior to TRIFLURALIN 10G application.

NOTE: DO NOT PLOW (MOLDBOARD) LAND PRIOR TO TRIFLURALIN 10G APPLICATION.

METHOD OF APPLICATION
Use a properly calibrated granular applicator to apply TRIFLURALIN 10G uniformly to the soil surface. Adjust the granular applicator to provide the required amount of TRIFLURALIN 10G. Each applicator should be checked frequently to ensure that the correct rate of TRIFLURALIN 10G is being applied. Ensure that the TRIFLURALIN 10G is applied uniformly to the entire soil surface. Avoid concentration of granules in narrow bands, etc. Incorporate TRIFLURALIN 10G within 24 hours of application and in the same direction as the application. Break all soil clods and lumps during incorporation. Susceptible crops in rotation will not be damaged if Trifluralin 10G is applied uniformly. Avoid over-lapping application.
NOTE: DO NOT APPLY TRIFLURALIN 10G BY AIRCRAFT.

INCORPORATION
Incorporate only with disc implements or cultivators. Deep tillage cultivators are not recommended. A tandem disc is recommended for the first incorporation. TRIFLURALIN 10G should be incorporated within 24 hours after application. Both incorporations should be to the depth of 8-10 cm (3-4 inches). The second incorporation must be at right angles to the first. Disc implements should be operated at 6-10 km/h (4-6 mph) and cultivators at 10-13 km/h (6-8 mph).
NOTE:
-For maximum weed control and crop tolerance incorporate TRIFLURALIN 10G to a depth of 8-10 cm (3-4 inches) only.
-Use a disc implement when incorporating TRIFLURALIN 10G on stubble or trashy soils.
-Cultivators should be used for TRIFLURALIN 10G incorporation when soils are in good working condition.
-Delay the second incorporation at least 5 days to allow greater release of TRIFLURALIN 10G and more effective weed control.

INSTRUCTIONS FOR SPRING APPLICATION
A TRIFLURALIN 10G spring pre-plant incorporated application for weed control during the crop year is recommended in Manitoba only. Apply Spring rates and follow incorporation instructions. Ensure good seedbed preparation through proper tillage. Do not apply TRIFLURALIN 10G to Barley, Flax or Lentils in the Spring.

INSTRUCTIONS FOR SUMMER APPLICATION
Apply TRIFLURALIN 10G to summerfallow between June 1 and September 1 using the summer rate for weed control in flax, rapeseed (canola), triazine tolerant rapeseed (canola) or fababeans in the following year. Incorporate TRIFLURALIN 10G within 24 hours after application. All subsequent incorporations may be done whenever resistant weed growth occurs for the remainder of the fallow season. A shallow tillage is required once the soil has warmed prior to planting the following Spring. This is best done with a vibrashank cultivator or disc implement cutting to a depth of 5-8 cm (2-3 inches) and is required for seedbed preparation.

INSTRUCTIONS FOR FALL APPLICATION
Apply TRIFLURALIN 10G in the Fall between September 1 and soil freeze-up for weed control in the following year. Use Fall rates and follow incorporation instructions. Do not delay initial incorporation more than 24 hours after application. The second incorporation to the recommended depth may be done in the Spring at the time of seedbed preparation. A shallow tillage prior to seeding is required the following Spring if both incorporations are done in the fall. This shallow tillage is best done with a vibrashank cultivator or disc implement cutting to a depth of 5-8 cm (2-3 inches). Both incorporations done in the Fall is preferred. For application of TRIFLURALIN 10G to Barley and to Lentils and Flax refer to the special sections on these crops.

NOTE:
Ensure a Spring tillage operation is completed to a depth of 5-8 cm (2-3 inches) with either a disc implement or vibrashank cultivator following Summer or Fall application of TRIFLURALIN 10G and prior to seeding. This should be done when the soil is warm enough to promote germination. Ensure weed seedlings are destroyed and not transplanted during the operation. Seed into a well prepared seedbed which is weed free.

SPECIAL INSTRUCTIONS FOR BARLEY
- Application of TRIFLURALIN 10G to barley is recommended as a fall treatment only.
- Barley is a fast-emerging, fast-growing cereal that has great natural competitive ability once established.
DO NOT USE BARLEY RATES OF APPLICATION IN OTHER REGISTERED CROPS. SEE THE RATE OF APPLICATION SECTIONS FOR OILSEED AND SPECIAL CROPS AND FOR LENTILS AND FLAX WHEN USING TRIFLURALIN 10G ON THESE CROPS RESPECTIVELY.
- Initial incorporation must be within 24 hours of TRIFLURALIN 10G application and to a depth of 8-10 cm (3-4 inches). The second incorporation should also be done in the fall at right angles to the first. For maximum effectiveness delay the second incorporation for 5 days.
- When using the lower rate of TRIFLURALIN 10G some wild oats and wild buckwheat may escape the herbicidal action. Lower areas of fields with high wild oat populations should be tilled prior to seeding the barley in order to reduce the wild oat density.
- Use the higher rate of TRIFLURALIN 10G on all soils with 6-10% organic matter except sand and sandy loam.
- Do not apply TRIFLURALIN 10G for barley on land treated with TRIFLUREX, TREFLAN, EDGE,
TRIFLURALIN, HERITAGE or RIVAL since June 1 of the previous year.
- Do not apply to soils containing less than 2% organic matter.
- Seeding should be done with drills and into a moist, warm seedbed. Do not seed when soil conditions are cold. If seeding with a discer or air seeder avoid variable seeding depth and ensure a firm seedbed by packing after seeding.
- Do not seed early when soil conditions are cold.
- Some early season effects may be noticed on the barley, however these effects are only temporary and the crop will recover to full yield potential.
- Application to severely eroded knolls may result in reduced crop stand.
- Application to fields with wide variances in soil organic matter or soil texture can result in reduced crop tolerance and variable weed control.
- See the above chart for correct application rates of TRIFLURALIN 10G on barley.

SPECIAL INSTRUCTIONS FOR FLAX (Do Not Use On Linolenic Acid Varieties) AND LENTILS

Application of Trifluralin 10G to flax may be made in summer or fall. Apply to lentils in fall only. Both incorporations should be done in the fall (summer) prior to seeding flax or lentils in the spring. To ensure a firm seedbed and maintain a constant depth of planting, a shallow tillage and a packed seedbed in the spring is recommended. Seed with a drill to a depth of 2-4 cm (¾ - 1½ inches) into a moist and firm seedbed. Seed flax and lentils when soil temperatures are warm and greater than 6o C (42o F) This is usually after mid-May. Environmental factors that are referred to in the "DIRECTIONS FOR USE IN ALL CROPS" section may cause crop injury and reduced yields.
