Section 10: Application Instructions and Cautions

 

·      Apply only once per crop cycle (in the fall or spring).

·      For best results, apply to emerged, young, actively growing weeds. Weed control may be reduced when weeds are under stress due to severe weather conditions, drought, very cold temperatures, etc. Weed control may be reduced if herbicide application is made under dry, dusty conditions, especially in wheel track areas.

·      Under cool and/or dry conditions activity may be reduced or delayed. Weed control may also be reduced if application is made when weeds are dust covered or in the presence of heavy dew, fog, or mist/rain.

·      Follow directions under SECTIONS 8, 9 and 10 for the correct rate and timing of application.

·      Avoid contact with desirable plants or crops either from direct application or from spray drift as severe damage may occur.

·      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 or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

·      This product may be tank mixed with a fertilizer, a supplement, or with registered pest control products, whose labels also allow tank mixing, provided the entirety of both labels, including Directions For Use, Precautions, Restrictions, Environmental Precautions, and Spray Buffer Zones are followed for each product. In cases where these requirements differ between the tank mix partner labels, the most restrictive label must be followed. Do not tank mix products containing the same active ingredient unless specifically listed on this label.

·      In some cases, tank mixing pest control products can result in reduced pesticide efficacy or increased host crop injury. The user should contact Bayer CropScience Inc. at 1-888-283-6847 or www.cropscience.bayer.ca for information before applying any tank mix that is not specifically recommended on this label.

When tank mixes are permitted, consult the labels of the tank mix partners and observe the largest (most restrictive) spray buffer zone of the products involved in the tank mixture and apply using the coarsest spray (ASABE) category indicated on the labels for those tank mix partners.

 

The spray buffer zones for this product can be modified based on weather conditions and spray equipment configuration by accessing the Spray Buffer Zone Calculator on the Pest Management Regulatory Agency web site.

 

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 (ASABE) coarse classification. Boom height must be 60 cm or less above the crop or ground.

·      Application of OLYMPUS Herbicide should be made using a minimum of 46.8 litres of water per hectare, at a pressure of 275 kPa, or 310 kPa if using check valves, and at a ground speed of 6–8 kph.

·      When tank mixing OLYMPUS Herbicide with a tank mix partner, ensure you read the tank mix partner label for minimum water recommendations.

·      The use of 80° or 110° flat fan nozzles is recommended for optimum spray coverage.

·      Do not use flood jet nozzles, controlled droplet application equipment or SPRAFOIL equipment.

·      Uniform, thorough coverage is important to obtain consistent weed control. Higher water volumes should be used under dense crop and weed canopies to ensure thorough coverage of the target weeds.

·      Avoid overlapping; shut off spray boom while starting, turning, slowing or stopping to prevent crop injury from over-application.

 

AERIAL APPLICATION:

 

·      DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply when wind speed is greater than 16 km/h at flying height at the site of application. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASABE) coarse classification. To reduce drift caused by turbulent wingtip vortices, the nozzle distribution along the spray boom length MUST NOT exceed 65% of the wing- or rotorspan.

·      Apply OLYMPUS Herbicide (ONLY with the recommended tank mix partners that are registered for aerial use) in no less than 28.1 litres of water per hectare at a pressure no less than 300 kPa.

·      Apply only by fixed-wing or rotary aircraft equipment which has been functionally and operationally calibrated for the atmospheric conditions of the area and the application rates and conditions of this label.

·      Label rates, conditions and precautions are product specific. Read and understand the entire label before opening this product. Apply only at the rate recommended on this label.

·      Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate marking devices.

Aerial Use Precautions:

·      Read and understand the entire label before opening this product. If you have questions, call Bayer CropScience Inc. at 1-888-283-6847 or obtain technical advice from the distributor or your provincial agricultural representative.

·      Apply only when meteorological conditions at the treatment site allow for complete and even crop coverage. Apply only under conditions of good practice specific to aerial application as outlined in the National Aerial Pesticide Application Manual, developed by the Federal/Provincial/Territorial Committee on Pest Management and Pesticides.

·      Do not apply to terrain where there is a potential for surface run-off to enter aquatic systems.

·      Do not apply if rain is expected within 1 hour after spraying. If tank mixing, consult the tank mix partner label and respect the most restrictive interval.

 

Aerial Operator Precautions:

·      Do not allow the pilot to mix chemicals to be loaded onto the aircraft. Loading of premixed chemicals with a closed system is permitted.

·      It is desirable that the pilots have communication capabilities at each treatment site at the time of application.

·      The field crew and the mixer/loaders must wear chemical resistant gloves, coveralls and goggles or face shield during mixing/loading, cleanup and repair. Follow the more stringent label precautions in cases where the operator precautions exceed the generic label recommendations on the existing ground boom label.

·      All personnel on the job site must wash hands and face thoroughly before eating and drinking.

·      Protective clothing, aircraft cockpit and vehicle cabs must be decontaminated regularly.

 

Product Specific Precautions:

·      Read and understand the entire label before opening this product. If you have questions, call the manufacturer at 1-888-283-6847 or obtain technical advice from the distributor or your provincial agricultural representative.

 

     

Section 11: Livestock Feeding and Pre-harvest Intervals

 

DO NOT harvest Wheat for grain or straw within 71 days of application.

If tank mixing, always respect the maximum Pre-Harvest Interval stated on the labels of all the tank mix products.

 

 

Section 12: Rotational Crop Recommendations

 

OLYMPUS Herbicide breakdown in the soil is due mainly to microbial activity. It can be affected by soil temperature and moisture. Conditions that accelerate the breakdown of OLYMPUS Herbicide include adequate soil moisture and adequate soil temperatures to support microbial activity. Likewise, OLYMPUS Herbicide breakdown can be slowed under dry, cold conditions. When making rotational cropping decisions, soil moisture and soil temperature conditions since application should be considered.

 

Only the following crops have been field tested to indicate they may be safely planted at the prescribed interval after an application of OLYMPUS Herbicide. To avoid the possibility of injury to subsequent crops after an application of the recommended rate of OLYMPUS Herbicide, follow the crops and replanting interval which appear on this label, and if tank mixing on the label of the tank mix partner, and always observe the most restrictive replanting interval. A field bioassay must be conducted the year prior to growing any other crop of interest to confirm crop safety.

Section 13: Mixing Instructions

 

OLYMPUS Herbicide must be applied with properly calibrated and clean sprayer equipment.

Prior to adding OLYMPUS Herbicide to the spray tank, ensure that the spray tank is thoroughly clean (see SECTION 14 “Sprayer Cleanup”). In-line strainers and nozzle screens should be clean and 50 mesh or courser.

 

1.     Fill the spray tank ¼ to ½ full with clean water and begin agitation or bypass.

2.     Add the appropriate rate of OLYMPUS Herbicide, as specified under SECTION 8, directly to the spray tank. Maintain sufficient agitation during both mixing and application.

3.     Add tank mix partner.

4.     Fill the spray tank with balance of water required.

5.     Maintain sufficient agitation during both mixing and application of OLYMPUS Herbicide.

 

OLYMPUS Herbicide may settle if left standing without agitation. If the spray solution is allowed to stand for one hour or more, re-agitate the spray solution for a minimum of 10 minutes before application.

 

 

Section 14: Sprayer Cleanup

 

Before and after using OLYMPUS Herbicide always complete a thorough cleaning of the spray tank, lines and filters. The following procedures are recommended:

 

1.     Drain the tank completely, and then wash out tank, boom and hoses with clean water. Drain again.

2.     Half fill the tank with clean water and add ammonia (i.e., 3% domestic ammonia solution) at a dilution rate of 1% (i.e., 1 litre of domestic ammonia for every 100 litres of rinsate). Complete filling of the tank with water. Agitate/recirculate and flush through boom and hoses. Leave agitation on for 10 minutes. Drain tank completely.

3.     Repeat step 2.

4.     Remove nozzles and screens and soak them in a 1% ammonia solution. Inspect nozzles and screens and remove visible residues.

5.     Flush tank, boom, and hoses with clean water.

6.     Inspect tank for visible residues. If present, repeat step 2.

7.     Dispose of rinsings in accordance with provincial regulations.

 

 

Section 15: Herbicide Resistance Management

 

For resistance management, OLYMPUS Herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to OLYMPUS 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:

1.  Where possible, rotate the use of OLYMPUS Herbicide or other Group 2 herbicides within a growing season (sequence) or among growing seasons with different herbicide Groups that control the same weeds in a field.

2.  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.

3.  Herbicide use should be based on an integrated pest management program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), 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.

4.  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.

5.  Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.

6. Have suspected resistant weed seeds tested by a qualified laboratory to confirm resistance and identify alternative herbicide options.

7. 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.
