DIRECTIONS FOR USE
GENERAL INFORMATION
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.

REGISTERED CROPS 
RIVAL 10G is a specially formulated herbicide for the control of certain annual grassy and broadleaf weeds in Rapeseed (Canola), Barley (Fall application only), Flax (except low linolenic acid varieties, Summer and Fall application only), Sunflowers, Mustard, Lentils (Fall and Summer application only), Peas (Field and Processing), Fababeans, and Triazine Tolerant Rapeseed (Canola). RIVAL 10G can also be used on summerfallow followed by Wheat in rotation providing weed control in both years; as well, it can be applied in the Fall on summerfallow or stubble for Green and Yellow Foxtail control the following year in Wheat. See the Special Section titled “DIRECTIONS FOR USE IN WHEAT”.

RIVAL 10G MUST NOT BE USED 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.

FALL APPLICATIONS OF PRE-EMERGENCE HERBICIDES 
For reasons of soil conservation Nufarm Agriculture Inc. does not recommend the Fall application of RIVAL 10G to soils which are subject to erosion by wind, water or other factors. Fall application to summerfallow under certain conditions such as low trash cover or light textured soils may predispose the field to wind and/or water erosion and is not recommended. Read all directions carefully before applying RIVAL 10G.

RESISTANCE MANAGEMENT RECOMMENDATIONS 
For resistance management, RIVAL 10G is a Group 3 herbicide. Any weed population may contain or develop plants naturally resistant to RIVAL 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 RIVAL 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 Nufarm Agriculture Inc. at 1-800-868-5444 or at www.nufarm.ca.

DIRECTIONS FOR USE IN ALL CROPS (INCLUDING WHEAT) 
Do not apply to soils which contain more than 15 per cent organic matter such as peat or muck soils (maximum 10 per cent organic matter on Barley).
Do not apply to wet soils that are subject to excessive flooding.
Do not apply to soils that are extremely lumpy, cloddy or in poor working condition.
For maximum weed control and crop tolerance, follow label directions at all times. Read all directions before applying RIVAL 10G.

CAUTION 
Application of RIVAL 10G 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 RIVAL 10G application and crop maturity (harvest). If these soils are flooded for a considerable period of time (3 weeks or more) the result may be no weed control at all. When used according to label directions, RIVAL 10G will not damage the treated crop. Emerging crop, weakened from factors such as deep planting, excessive moisture, cold temperatures, seedling disease, poor soil fertility, drought and saline soils may increase the risk of damage from RIVAL 10G resulting in a delay in crop maturity and/or reduced yields. Highly sensitive crops such as Tame Oats, Sugarbeets and small seeded annual grasses (Timothy, Canary Seed Grass and Creeping Red Fescue) should not be grown in rotation in the year following RIVAL 10G application.

SPECIAL INSTRUCTIONS FOR CROP ROTATIONS 
The rate of breakdown of RIVAL 10G, in the soil, is influenced by environmental factors which occur during the year of control, and those of the following spring, i.e., May 1stMay 1st. If precipitation during this period is below normal, the level of carryover into the following growing season will be increased.
Crop 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 RIVAL 10G application. To reduce injury to rotational crops, seed the crops shallowly into a warm, moist seedbed.

DIRECTIONS FOR USE IN OILSEED CROPS, SPECIAL CROPS AND BARLEY (For Use on Summerfallow-Wheat Rotations and for Green Foxtail Control in Wheat, see “DIRECTIONS FOR USE IN WHEAT” Section)

SUSCEPTIBLE WEEDS ANNUAL GRASSES: 
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. The above weeds will be controlled when RIVAL 10G is applied at recommended rates and used as directed. Ensure that all incorporation directions are followed. Some Wild Oats and Wild Buckwheat may escape the RIVAL 10G herbicidal action, however the crop competition will effectively suppress the escaped weeds so that little or no competition results with the crop. RIVAL 10G controls weeds as they germinate. This occurs as the soil warms and soil temperatures approach 6 C.

TIME OF APPLICATION 
RIVAL 10G is applied before the crop is planted and before weed emergence. It is incorporated thoroughly into the soil to provide herbicidal action that will control all susceptible weeds. RIVAL 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
Before applying RIVAL 10G, ensure that all emerged and existing weeds have been eliminated through discing, cultivation or by chemical control. RIVAL 10G can be applied to stubble or trashy soils; however, heavy trash soils should be thoroughly disced prior to RIVAL 10G application in order to allow product penetration into the soil surface. Ensure that all large soil clods are broken before RIVAL 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 RIVAL 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 RIVAL 10G application.
NOTE: DO NOT PLOW (MOLDBOARD) LAND PRIOR TO RIVAL 10G APPLICATION.

METHOD OF APPLICATION 
Apply RIVAL 10G uniformly to the soil surface using a properly calibrated granular applicator. Using the equipment guidelines provided in this label or by the equipment manufacturer adjust the applicator to provide the required rate of RIVAL 10G. These guidelines should only be used as starting points for equipment calibration and each applicator should be checked frequently to ensure that the correct rate of RIVAL 10G is being applied. Ensure that RIVAL 10G is applied uniformly to the entire soil surface and avoid concentration of granules in narrow bands, etc. Incorporate RIVAL 10G in the same direction as the application and within 24 hours of application. Ensure that all soil clods and lumps are broken during incorporation. Susceptible crops in rotation will not be damaged if RIVAL 10G is applied uniformly. Avoid over-application.
NOTE: DO NOT APPLY RIVAL 10G BY AIRCRAFT.

INCORPORATION
Incorporate with disc implements or cultivators only. Deep tillage cultivators are not recommended. A tandem disc is recommended for the first incorporation. Do not delay the first incorporation more than 24 hours after RIVAL 10G application. Both incorporations should be to the depth of 8-10 cm. The second incorporation must be at right angles to the first. Disc implements should be operated at 6-10 km/h and cultivators at 10-13 km/h. 

NOTE:
Incorporate RIVAL 10G to a depth of 8-10 cm only for maximum weed control and crop tolerance.
Use a disc implement when incorporating RIVAL 10G on stubble or trashy soils.
Cultivators should only be used for RIVAL 10G incorporation when soils are in good working condition.
To allow greater release of RIVAL 10G and more effective weed control, delay the second incorporation for at least 5 days.

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

INSTRUCTIONS FOR SUMMER APPLICATION 
For weed control in Flax, Rapeseed (Canola), Triazine Tolerant Rapeseed (Canola), Peas, Lentils, Mustard, Sunflowers and Fababeans the following year, apply RIVAL 10G to summerfallow between June 1 and September 1 using the summer rate and incorporate within 24 hours after application of RIVAL 10G. All subsequent incorporations may be done whenever resistant weed growth occurs for the remainder of the fallow season. Prior to planting the following spring, a shallow tillage once the soil has warmed is required. This is required for seedbed preparation and is best done with a Vibrashank cultivator or disc implement cutting to a depth of 5-8 cm. For summer application of RIVAL 10G to Lentils and Flax, refer to the Special Sections on these crops.

INSTRUCTIONS FOR FALL APPLICATION 
For weed control in the following year, apply RIVAL 10G in the fall between September 1 and soil freeze-up, using Fall rates and following incorporation instructions. Do not delay initial incorporation more than 24 hours after application. The second incorporation may be done in the spring at the time of seedbed preparation and to the recommended depth. If both incorporations are done in the fall, a shallow tillage in the following spring and prior to seeding is required. This shallow tillage is best done with a Vibrashank cultivator or disc implement cutting to a depth of 5-8 cm. It is preferred if both incorporations are done in the fall. For application of RIVAL 10G to Barley, Lentils and Flax refer to the Special Sections on these crops respectively.
NOTE: Following summer or fall application of RIVAL 10G and prior to seeding, ensure a spring tillage operation is completed to a depth of 5-8 cm with either a disc implement or a Vibrashank cultivator. 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 weed-free and well-prepared seedbed.

SPECIAL INSTRUCTIONS FOR FLAX (EXCEPT LOW LINOLENIC ACID VARIETIES) AND LENTILS 
Application of RIVAL 10G to Flax and Lentils may be made in summer or fall.
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 spring are recommended.
Seed with a drill to a depth of 2-4 cm into a moist and firm seedbed.
Seed Flax and Lentils when soil temperatures are warm and greater than 6 C. 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.

RIVAL 10G GRANULES FOR LENTILS AND FLAX (EXCEPT LOW LINOLENIC ACID VARIETIES)

SPECIAL INSTRUCTIONS FOR BARLEY 
Application of RIVAL 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 RIVAL 10G ON THESE CROPS RESPECTIVELY.
Initial incorporation must be within 24 hours of RIVAL 10G application and to a depth of 8-10 cm. 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 RIVAL 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 RIVAL 10G on all soils with 6-10 per cent organic matter except sand and sandy loam.
Do not apply RIVAL 10G for Barley on land treated with RIVAL, Treflan, Heritage or Triflurex since June 1 of the previous year.
Do not apply to soils containing less than 2 per cent organic matter.
Seeding should be done with drills and into 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 following chart for correct application of RIVAL 10G on Barley.

RIVAL 10G GRANULES FOR WHEAT
DIRECTIONS FOR USE IN WHEAT 
RIVAL 10G USE ON SUMMERFALLOW FOLLOWED BY WHEAT IN ROTATION.
RIVAL 10G can be mixed (incorporated) into the soil during the summerfallow year to control several weeds during both years of the summerfallow-Wheat rotation. RIVAL 10G will only control susceptible weeds as they germinate and will not control established weeds.

REGISTERED CROPS 
All Spring Wheat varieties including Semi-Dwarf, Hard Red Spring and Durum Wheat.

NOTE: The above weeds will be controlled when RIVAL 10G is applied at recommended rates and used as directed. Ensure that all incorporation directions are followed. During the fallow year, susceptible weeds will not be fully controlled until after the second incorporation when there has been a uniform layer of soil treated with RIVAL 10G established.

TIME OF APPLICATION 
RIVAL 10G can be applied to the summerfallow between May 1st and July 31st. Early application is recommended so that the greatest benefits of weed control during the fallow year can be achieved. If possible, apply RIVAL 10G just prior to the first summerfallow operation.

LAND PREPARATION 
RIVAL 10G can be applied to stubble or trashy soils as well as pre-worked stubble. Very heavy trash soils should be pre-worked prior to RIVAL 10G application in order to allow product penetration onto the soil surface. If green growth is heavy, destroy this growth before application of RIVAL 10G. This growth can be removed either by cultivation or by chemical control methods.

METHOD OF APPLICATION 
Apply RIVAL 10G uniformly to the soil surface using a properly calibrated granular applicator. Incorporate RIVAL 10G in the same direction as application and within 24 hours of application. Avoid over-application.

DO NOT APPLY RIVAL 10G BY AIRCRAFT.

INCORPORATION 
Incorporate with cultivators or disc implements only. Deep tillage cultivators do not provide the best mixing action, however may be needed for the first fallow operation (incorporation) if trash conditions warrant it. Do not delay the first incorporation more than 24 hours after RIVAL 10G application. Incorporate RIVAL 10G at a working speed of 8-13 km/hr. The second incorporation must not be done any sooner than 5 days after the first incorporation and can be delayed until new weed regrowth requires a cultivation or discing. The second incorporation must be at right angles to the first. Both incorporations must be to a depth of 5-8 cm. Subsequent workings must be no deeper than 8 cm. After the two incorporations, additional shallow tillage may be required to control resistant weed growth and provide more uniform mixing of RIVAL 10G into the soil especially if a deep tillage cultivator was used for the first incorporations. Do not apply and incorporate RIVAL 10G when the soil is in poor working condition (wet, lumpy, or cloddy).

SEEDBED PREPARATION 
Ensure there is a well-prepared seedbed by providing a spring tillage operation using either a disc implement or field cultivator. (This operation may not be necessary if seeding with an air-seeder or discer.) Seed into a moist, warm and firm seedbed in order to promote quick germination. Ensure weed seedlings are destroyed and not transplanted during the spring operations. Seeding implements must be set to place the Wheat at a 3-6 cm depth. SHALLOW SEEDING IS ESPECIALLY IMPORTANT FOR SEMI-DWARF WHEAT VARIETIES. The seedbed should be firmly packed or harrowed after seeding to promote good germination.

NOTE: TO AVOID WHEAT INJURY, USE GOOD QUALITY SEED AND FOLLOW SEEDING PRACTICES WHICH PROMOTE GOOD GROWING CONDITIONS. AVOID DEEP SEEDING, LOOSE SEEDBEDS, AND SEEDING INTO COLD SOILS.

CAUTION When applying RIVAL 10G for weed control in Wheat, drought conditions during the fallow year after RIVAL 10G application may result in higher than normal carry-over of RIVAL 10G into the crop year. To reduce the possibility of Wheat damage under these circumstances, seed the Wheat at a higher seeding rate, seed shallow, and seed into a moist warm, and well-prepared seedbed.

RIVAL 10G USE FOR FALL APPLICATION FOR CONTROL OF GREEN AND YELLOW FOXTAIL (WILD MILLET) IN WHEAT 
RIVAL 10G can be applied and mixed (incorporated) into the soil on summerfallow or stubble land between September 1st and freeze-up in order to control Green and Yellow Foxtail (Wild Millet) during the following crop year in Wheat. RIVAL 10G will only control Foxtail as it germinates and will not control established Foxtail plants. 

REGISTERED CROPS 
All Spring Wheat varieties including Semi-Dwarf, Hard Red Spring and Durum Wheat.

WEEDS CONTROLLED 
Green and Yellow Foxtail (Wild Millet).

TIME OF APPLICATION 
RIVAL 10G can be applied in the Fall between September 1 and soil freeze-up for Foxtail control the following year.

LAND PREPARATION 
RIVAL 10G can be applied to summerfallow or to stubble. The stubble may be standing or pre-worked, however very heavy trash soils should be pre-worked prior to RIVAL 10G application in order to allow product penetration onto the soil surface. If green growth is heavy, destroy this growth before application of RIVAL 10G. This growth can be removed either by cultivation or by chemical control methods. If the stubble has been burned, cultivate prior to RIVAL 10G application.

METHOD OF APPLICATION 
Apply RIVAL 10G uniformly to the soil surface using a properly calibrated granular applicator. Incorporate RIVAL 10G in the same direction as application and within 24 hours of application. Avoid over application. DO NOT APPLY RIVAL 10G BY AIRCRAFT.

NOTE: DO NOT APPLY RIVAL 10G IN THE FALL (FOR FOXTAIL CONTROL THE FOLLOWING YEAR IN WHEAT) ON LAND THAT WAS TREATED WITH RIVAL, TREFLAN, HERITAGE, OR TRIFLUREX IN EITHER THE CURRENT YEAR OR THE PREVIOUS CROP YEAR.

INCORPORATION 
Incorporate with cultivators or disc implements only. Deep tillage cultivators do not provide the best mixing action however may be needed for the first incorporation if trash conditions warrant it. Do not delay the first incorporation more than 24 hours after RIVAL 10G application. Incorporate RIVAL 10G at a working speed of 8-13 km/hr. The second incorporation must be delayed at least 5 days after the first and must be done at right angles to the first incorporation. The second incorporation may be done in the fall or in the spring prior to seeding the Wheat crop. Both incorporations must be to a depth of 5-8 cm. Subsequent workings must be no deeper than 8 cm. Do not apply and incorporate RIVAL 10G when the soil is in poor working condition (wet, lumpy, or cloddy). Do not incorporate with rodweeders, harrows, or hoe drills. 

RATE OF APPLICATION 

NOTE: DO NOT APPLY RIVAL 10G IN THE FALL FOR FOXTAIL CONTROL IN WHEAT WHERE SOIL ORGANIC MATTER IS LESS THAN 2 PER CENT OR GREATER THAN 8 PER CENT.

SEEDBED PREPARATION 
Ensure there is a well-prepared seedbed by providing a spring tillage operation using either a disc implement or field cultivator. (This operation may not be necessary in seeding with an air-seeder or discer.) Seed into a moist, warm and firm seedbed in order to promote quick germination. Ensure weed seedlings are destroyed and not transplanted during the spring operations. Seeding implements must be set to place the Wheat seed at a 3-6 cm depth. SHALLOW SEEDING IS ESPECIALLY IMPORTANT FOR SEMI-DWARF WHEAT VARIETIES. The seedbed should be firmly packed or harrowed after seeding to promote good germination.

NOTE: TO AVOID WHEAT INJURY, USE GOOD QUALITY SEED AND FOLLOW SEEDING PRACTICES WHICH PROMOTE GOOD GROWING CONDITIONS - AVOID DEEP SEEDING, LOOSE SEEDBEDS, AND SEEDING INTO COLD SOILS.

CAUTION APPLICATION OF RIVAL 10G TO SEVERELY ERODED HILLS FOR WEED CONTROL IN WHEAT MAY RESULT IN REDUCED CROP STAND. ALL PRECAUTIONS AND DIRECTIONS FOR USE UNDER GENERAL INFORMATION ON THE FIRST PART OF THIS LABEL APPLY TO THE USE OF RIVAL 10G IN WHEAT AS WELL AS OTHER CROPS.
