General Instructions

 

Insecticide Resistance Management Strategy

Insecticide Resistance Management Strategy for green peach aphid in various crops: Contact your local supplier, Cheminova representative or local agricultural department agronomist. Also available at website www.croplife.org.au.

 

Insecticide Resistance Management Strategy for other aphids, whitefly and melon thrips: Do not apply Couraze 200 SC Insecticide in consecutive sprays. Rotate with registered insecticides from other groups.

 

Confined environments such as glasshouses

Annuals: Do not apply more than one spray of Couraze 200 SC Insecticide to any one crop.

 

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

 

Mixing / Application

 

Prior to pouring, shake container vigorously, then add the required quantity of Couraze 200 SC Insecticide to water in the spray vat while stirring or with agitators in motion.

 

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 run-off) 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.

 

Application

 

APPLICATION (COTTON)

Thorough coverage of cotton plants is essential to achieve maximum performance from Couraze 200 SC Insecticide plus Pulse. Equipment should be calibrated to achieve a minimum of 60 droplets/cm2 on the target foliage. A droplet Volume Median Diameter (VMD) for optimum performance from Couraze 200 SC Insecticide plus Pulse is dependent on equipment and is defined below. Do not apply when unfavourable environmental conditions may reduce the quality of spray coverage.

 

Ground Application (Cotton)

Application using ground equipment should be made using hollow cone nozzles with a minimum spray volume of 100 L/ha. Hollow cone nozzles are recommended but if flat fan nozzles are used, higher water volumes will be required and nozzles should be configured to ensure thorough coverage. A droplet VMD of 150 - 180 microns must be used. Where multiple nozzles per row are used, they should be of the same specification to ensure that each nozzle contributes an equal proportion of the required dose. Where multiple nozzles per row are used (particularly for banded applications) ensure the correct nozzle overlap pattern is achieved on the target foliage. Banded applications less than 100% are not recommended beyond the 15 node crop stage.

 

Aerial Application (Cotton)

Apply in a minimum spray volume of 25 L/ha. A droplet VMD of 120 - 150 microns must be used. Do not exaggerate swath width or exceed a swath width of 20 to 22 m. Do not apply Couraze 200 SC Insecticide plus Pulse using Ultra Low Volume (ULV) methods. The use of large droplet placement equipment is not recommended.

 

Compatibility

Couraze 200 SC Insecticide is compatible with Antracol, Baycor, and Nitofol. 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 Ornamentals

Cheminova Couraze 200SC 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 first, in order to ascertain their reaction before treating the whole crop.

 

Export Of Treated Produce

Growers should note that suitable MRLs or import tolerances do not exist in all markets for edible produce treated with Couraze 200 SC Insecticide. If you are growing edible produce for export, please check with Cheminova for the latest information on MRLs and export tolerances before using Couraze 200 SC Insecticide.

 

Resistance Warning

 

For insecticide resistance management, Couraze 200 SC Insecticide is a Group 4A insecticide. Some naturally occurring insect biotypes resistant to Couraze 200 SC Insecticide 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 200 SC Insecticide and other Group 4A insecticides are used repeatedly. The effectiveness of Couraze 200 SC Insecticide 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 200 SC Insecticide to control resistant insects. Couraze 200 SC Insecticide may be subject to specific resistance management strategies. For further information contact your local supplier, Cheminova representative or local agricultural department agronomist.

 

Protection of wildlife, fish, crustaceans and environment

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

 

A spray drift minimisation strategy should be employed at all times when aerially applying sprays. The strategy envisaged is exemplified by the cotton industry's Best Management Practices Manual.

 

Safety Directions

 

Harmful if swallowed. May irritate the eyes and skin. Repeated exposure may cause allergic disorders. Avoid contact with eyes and skin. When preparing product for use, wear cotton overalls buttoned to the neck and wrist and a washable hat, elbow-length PVC gloves and goggles. Wash hands after use. After each day's use, wash gloves, goggles and contaminated clothing.

 

Storage

Store in the closed, original container in a cool, well ventilated area. Do not store for prolonged periods in direct sunlight.

 

Disposal

Triple or preferably pressure rinse container before disposal. Add rinsings to spray tank. Do not dispose of undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers and product should not be burnt.
