Section 9:      Application Instructions and Use Limitations

 

9.1                   general reminders for successful operation

 

·               DO NOT apply more than two applications of LAUDIS Herbicide to field corn and seed corn or more than one application to sweet corn, per growing season.

·               Do not apply LAUDIS Herbicide to corn that exhibits injury from previous herbicides applications.

·               For best results, apply to emerged, young, actively growing weeds.

·               LAUDIS Herbicide will have an effect on weeds that are larger than the recommended leaf stage, however the speed of activity and level of control may be reduced.

·               Weed control may be reduced if the application is made when weeds are dust covered or in the presence of heavy dew, fog, and mist/rain or when weeds are under stress and not actively growing due to drought, heat, lack of fertility, flooding, or prolonged cool temperatures.

·               Under cool and/or dry conditions activity may be reduced or delayed. 

·               If crop is under stress due to abnormal environmental conditions, delay application until stress passes and after both crop and weeds have resumed active growth.

·               Follow directions under Section 8 for the correct rate and timing of application.

·               DO NOT apply when wind causes drift to off-site vegetation as injury may occur.  LAUDIS Herbicide delivered via drift or tank contamination can cause severe damage to other crops. Careful management of spray drift and tank cleanout is required (refer to section 9.3- SPRAY DRIFT MANAGEMENT and section 12-SPRAYER CLEAN-UP).

 

 

9.2                   ground application

 

·               Apply with groundboom equipment only. DO NOT APPLY USING AERIAL APPLICATION EQUIPMENT.

·               LAUDIS Herbicide can be applied broadcast in a minimum of 100 litres of water per hectare. For weed control in dense weed populations or under adverse growing conditions, 150 to 200 litres of water per hectare is recommended. Good coverage is essential to achieve optimum weed control.

·               Uniform, thorough spray coverage is important to achieve consistent weed control. Select nozzles and pressure that deliver MEDIUM spray droplets as indicated in nozzle manufacturer’s catalogs and in accordance with ASAE Standard S-572. Nozzles that deliver COARSE spray droplets may be used to reduce spray drift provided spray volume per hectare (L of water/ha) is increased to maintain coverage of weeds.

·               Flat fan nozzles of 80° or 110° are recommended for optimum post emergence coverage. Do not use nozzles that produce FINE (e.g. - Cone) or EXTRA COARSE (e.g. - Flood jet) spray droplets.

·               Typically, flat-fan nozzles operated at 200-400 kPa will deliver MEDIUM spray droplets, providing optimum spray coverage and canopy penetration. Lower pressure operation and/or higher volume flat fan nozzles typically deliver COARSE sprays. Refer to nozzle manufacturer catalogs.

·               Boom height should be based on the height of the crop – at least 33 centimetres above the crop canopy.

·               Air induction nozzles should be used at or near 550 kPa to produce a medium droplet size.

·               Proper agitation should be maintained within the tank to keep the product dispersed.

 

 

9.3         spray drift management and SPRAY buffer zones

 

 

 

 

 

 

 

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 S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground.

                                                           

DO NOT apply by air.

 

 

Spray buffer zones:

A spray buffer zone is NOT required for:

·      uses with hand-held application equipment permitted on this label.

 

The spray 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.

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 (ASAE) 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 Pesticides portion of the Canada.ca website.

 

 

9.4             ROTATIONAL CROPS and field bioassay

 

Only the following crops have been field tested to indicate they may be safely planted at the prescribed interval after an application of LAUDIS Herbicide.  To avoid the possibility of injury to subsequent crops after an application of the recommended rate of LAUDIS 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.

** Use of seed corn as an immediate plant back crop and a rotational crop must be approved by the contracting Seed Corn companies and comply with the directions given by the contractor.

 

FIELD BIOASSAY:

Select a representative area or areas of the field previously treated with LAUDIS Herbicide to plant your bioassay crop(s).  Be sure to consider factors such as size of field, soil texture, drainage and turn-around areas when selecting the site(s) that are most representative of the conditions in the field.  On large fields, more than one site may be needed in order to obtain reliable results.  Plant the test strips perpendicular to the direction in which the field was sprayed.  The strips should be long enough to cross the width of several spray swaths.   Large test strip areas are more reliable than small ones.  Use standard tillage and seeding equipment to plant the bioassay.  Prepare a seed bed and plant the crops and varieties you want the option of growing the following year.  It is important to use the same planting time, conditions, techniques and cultural practices you normally use to plant and grow the bioassay crop(s).  Also, plant into an adjacent area not treated with LAUDIS Herbicide to use as a comparison.  As the crop(s) emerges and grows, examine these key points in LAUDIS Herbicide-treated and non-treated areas:

 

▪   crop stand                                           ▪   plant colour and vigour

▪   root development                               ▪   yield

▪   rate of growth

 

Allow the bioassay crop(s) to grow to maturity while making your observations.  Do not overspray the test strips with herbicides that may damage the bioassay crop(s).  If the bioassay indicates that LAUDIS Herbicide residues are still present, continue cropping only to those crops listed on the label, and do not rotate to other crops until bioassay results indicate that susceptible crops are growing normally.  DO NOT ROTATE TO OTHER CROPS UNTIL BIOASSAY INDICATES NORMAL GROWTH WITH NO YIELD REDUCTIONS.

Section 11:  Mixing Instructions

 

LAUDIS Herbicide must be applied with clean and properly calibrated equipment. Prior to adding LAUDIS Herbicide, ensure that the spray tank, filters and nozzles have been thoroughly cleaned and that agitation system is properly working.

 

1.              Fill spray tank with 50% of the required volume of water, and begin agitation.

2.              Add the appropriate amount of LAUDIS Herbicide slowly to the spray tank or mixing system and ensure complete dispersion. Maintain and ensure thorough dispersion and sufficient agitation during both mixing and spraying.

3.             If tank mixing LAUDIS Herbicide with other registered herbicides follow the WAMLEGS [Wettable powders/ flowable, Agitate Anti-foaming compounds/buffers, Microcapsule suspension, Liquid and soluble, Emulsifiable concentrates, High load Glyphosates, Surfactants] mixing order system:

•   Add water soluble bags first

•   Followed by dry formulations, flowables, emulsifiable concentrates and then solutions.

•   Prepare no more spray mixture than is required for the immediate spray operation.

4.              Add the adjuvant.

5.              Add nitrogen fertilizer.

6.              Fill the spray tank with balance of water needed.

 

Proper agitation should be maintained within the tank to keep the product dispersed.

Apply LAUDIS Herbicide spray mixtures within 24 hours of mixing to avoid product degradation.

 

 

 

Section 12:  Sprayer Cleanup

 

Cleaning Equipment After LAUDIS Herbicide Application

Special attention must be given to cleaning equipment before spraying a crop other than corn. Mix only as much cleaning solution as needed.

 

1.     Flush tank, hoses, boom and nozzles with clean water.

2.     Prepare a cleaning solution of 1 gal of household ammonia per 25 gallons of water. Many commercial spray tank cleaners may be used.

3.     Use a pressure washer to clean the inside of the spray tank with this solution. Take care to wash all parts of the tank, including the inside top surface. If a pressure washer is not available, completely fill the sprayer with the cleaning solution to ensure contact of the cleaning solution with all internal surfaces of the tank and plumbing. Start agitation in the sprayer and thoroughly recirculate the cleaning solution for at least 15 minutes. All visible deposits must be removed from the spraying system.

4.     Flush hoses, spray lines, and nozzles for at least 1 minute with the cleaning solution.

5.     Dispose of rinsate from steps 1-3 in an appropriate manner.

6.     Repeat steps 2-5.

7.     Remove nozzles, screens and strainers and clean separately in the ammonia solution after completing the above procedures.

8.     Rinse the complete spraying system with clean water.

 

 

Section 13:  Resistance Management Recommendations

 

For resistance management, LAUDIS Herbicide is a Group 27 herbicide. Any weed population may contain or develop plants naturally resistant to LAUDIS Herbicide and other Group 27 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 LAUDIS Herbicide or other Group 27 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 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.

4.         Monitor treated weed populations for 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 using 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.

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

6.         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.

7.         For further information or to report suspected resistance contact Bayer via internet at www.cropscience.bayer.ca or telephone at 1-888-283-6847.
