General Instructions

 

Insecticide Resistance Warning

 

For insecticide resistance management, Cheminova Couraze Classic Insecticide is a Group 4A insecticide. Some naturally occurring insect biotypes resistant to Couraze Classic and other Group 4A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Couraze Classic and other Group 4A insecticides are used repeatedly. The effectiveness of Couraze Classic on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Cheminova accepts no liability for any losses that may result from the failure of Couraze Classic to control resistant insects. Couraze Classic may be subject to specific resistance management strategies. For further information contact your local supplier, Cheminova representative or local agricultural department agronomist.

 

Resistance Management

 

Resistance Management Strategy (vegetables)

Do not apply more than one soil application of Couraze Classic to each crop.

 

Do not use Couraze Classic or any Group 4A insecticide as a foliar spray after soil application of Couraze Classic in that crop. Refer to district advice for local silverleaf whitefly resistance management strategies.

 

Insecticide Resistance Management Strategy for cotton aphid in cotton: Contact your local supplier, Cheminova representative or local agricultural department agronomist.

 

Insecticide Resistance Management Strategy for other aphids, whitefly and melon thrips: Do not apply Cheminova Couraze Classic Insecticide (or other group 4A insecticides) in consecutive sprays within and between seasons. Rotate with registered insecticides from other groups.

 

Confined environments such as glasshouses.

Annuals: Do not apply more than one spray of Cheminova Couraze Classic Insecticide to any one crop.

 

Perennials: Rotate with registered insecticides from other groups. Use a maximum of three sprays in any 12 month period.

 

Application

 

Application (Apples)

During late summer or autumn, apple trees with woolly aphid colonies or damage should be identified and marked for treatment the following season. At green tip to petal fall, apply 1 litre of the prepared Cheminova Couraze Classic Insecticide mixture to moist soil immediately around the base of the tree trunk. Ensure the mixture infiltrates the soil around the trunk and does not run off the soil. Control weeds before application. Do not disturb or remove the soil around the trunk during the season.

 

Application (sugarcane)

Apply only as a subsurface soil application. Apply in no less than 1.5 litres of water per 100 metres of cane row (equivalent to no less than 100 L/ha of water for single row cane with 1.52 m spacing between rows).

 

Greyback canegrub

Twin coulter method: Apply subsurface behind twin coulters to a depth of 100-125 mm. Coulters should be spaced 220 mm to 500 mm apart, one either side of the centre of the stool. Coulter slits should be in the sides or top of the stool mound rather than at the base. Narrow spacings may not be possible with advanced ratoon growth. DO NOT apply using narrow spacings if ratoon growth is advanced such that excessive crop damage from equipment may result. Single coulter method ('stool split'): Apply subsurface behind a single coulter in the centre of the stool. DO NOT apply using this method if ratoon growth is advanced such that excessive crop damage from equipment may result. This method is not suitable for all areas. Before using this method, consult your local Cheminova representative.

 

Childers canegrub

Twin coulter method: Apply subsurface behind twin coulters to a depth of 100- 125 mm. Coulters should be spaced 220 to 350 mm apart, with one coulter on either side of the centre of the stool.

 

Application (vegetables)

Refer to instructions in Critical Comments for each application method.

 

Export Of Treated Produce

Growers should note that MRLs or import tolerances do not exist in all markets for produce treated with Couraze Classic. If you are growing produce for export, please check with Cheminova for the latest information on MRLs and import tolerances before using Couraze Classic.

 

Note on Ornamentals

Cheminova Couraze Classic Insecticide has been used on a wide range of ornamental plant species without damage. However, some species and varieties are particularly sensitive to chemical sprays and as this is often related to local conditions it is advisable to treat only a small number of plants fi rst, in order to ascertain their reaction before treating the whole crop.

 

Compatibility

Cheminova Couraze Classic Insecticide is compatible with Antracol, Baycor,and Nitfol. Do not mix concentrates together but add each to the spray tank separately. As formulations of other manufacturers' products are beyond the control of Cheminova, all mixtures should be tested prior to mixing commercial quantities. As changes in climatic conditions can alter the sensitivity of plants to mixtures of sprays, Cheminova cannot be responsible for the behaviour of such mixtures.

 

Note on Vegetable Crops

Note for Vegetable Crops: potential migration of silverleaf whitefly from neighbouring crops

Adult silverleaf whitefly (SLWF) is controlled when they ingest a lethal dose of active ingredient by feeding on a Couraze Classic treated crop. However, in some very susceptible crops and varieties, the migration of large populations of adults from adjacent fields may result in significant feeding damage to the crop, although further reproduction and development of the pest will be prevented. To help prevent such damage it is important to minimise the migration of adult SLWF into a treated crop, e.g. by applying a 'clean-up' fast-acting insecticide to recently harvested crops. Consideration of factors such as planting sequences and timing, wind direction, variety selection, and general crop hygiene should also be integral to SLWF management. Crops should also be monitored for SLWF adult numbers after application of Couraze Classic, and appropriate fast acting insecticides for control of adults should be applied if economic thresholds are reached or excessive adult feeding damage is observed.

 

Mixing

 

Prior to pouring, shake container vigorously, then add the required quantity of Couraze Classic to water in the tank while stirring or with agitators in motion. Couraze Classic requires constant agitation in the tank.

 

Dilute Spraying (stone fruit)

Use a sprayer designed to apply high volumes of water up to the point of run-off and matched to the crop being sprayed.

 

Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of run-off. Avoid excessive run-off.

 

The required water volume may be determined by applying different test volumes, using different settings on the sprayer, from industry guidelines or expert advice.

 

Add the amount of product specified in the Directions for Use table for each 100 L of water. Spray to the point of run-off.

 

The required dilute spray volume will change and the sprayer set up and operation may also need to be changed, as the crop grows.

 

Concentrate Spraying (stone fruit)

Use a sprayer designed and set up for concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of runoff) and matched to the crop being sprayed.

 

Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume.

 

Determine an appropriate dilute spray volume (See Dilute Spraying above) for the crop canopy. This is needed to calculate the concentrate mixing rate. The mixing rate for concentrate spraying can then be calculated in the following way:

 

EXAMPLE ONLY

 

1. Dilute spray volume as determined above: For example 1500 L/ha

 

2. Your chosen concentrate spray volume: For example 500 L/ha

 

3. The concentration factor in this example is: 3 X (ie 1500 L / 500 L = 3)

 

4. As the dilute label rate is 25 mL/100 L for stone fruit, then the concentrate rate becomes 3 x 25, which is 75 mL/100 L of concentrate spray.

 

The chosen spray volume, amount of product per 100 L of water, and the sprayer set up and operation may need to be changed as the crop grows.

 

Do not use a concentrate rate higher than that specifi ed in the Critical Comments.

 

For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

 

Restraints Foliar application

For aphid, whitefl y and melon thrips resistance strategies where repeat applications are necessary see General Instructions.

 

DO NOT use on crops produced hydroponically or in glasshouses and other covered situations.

 

Soil application

DO NOT apply Couraze Classic or any other Group 4A Insecticide as a foliar spray after soil application of Couraze Classic in that crop.

 

DO NOT apply more than one application of Couraze Classic per crop for vegetables, or per ratoon crop for sugarcane.

 

Protection of wildlife, fish, crustaceans and environment

DO NOT contaminate streams, rivers or waterways with the chemical or used containers.

 

Imidacloprid is toxic to certain aquatic species.

 

Application should be planned to avoid run-off within 48 hours of application.

 

Application should not be made to wet/waterlogged soils. Application is not to be performed if heavy rains are expected to occur within 48 hours. Irrigation run-off from treated areas should be prevented from entering drains and waterways.

 

Sugarcane: Irrigation should not occur within 48 hours of application.

 

Vegetables (furrow spray pre-plant and plant hole drench applications): Irrigation within 48 hours of application should be minimal, and sufficient to reduce seedling stress only.
