General Instructions

 

Coragen insecticide has been specifically designed for use in Integrated Pest Management (IPM) schemes.  Coragen is an anthranilic diamide insecticide in the form of a suspension concentrate.  Coragen  is particularly active on Lepidopteran insect pests, primarily as a larvicide.  Before application monitor insect populations to determine whether or not there is a need for application of Coragen based on locally determined economic thresholds.  More than one treatment of Coragen insecticide may be required to control a population of pests.

 

Insect Resistance Warning

 

For insecticide resistance management Coragen insecticide is a Group 28 insecticide.

Some naturally occurring insect biotypes resistant to Coragen and other Group 28 insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Coragen and other Group 28 insecticides are used repeatedly. The effectiveness of Coragen on resistant individuals could be significantly reduced. Since the occurrence of resistant individuals is difficult to detect prior to use DuPont accepts no liability for any losses that may result from the failure of Coragen to control resistant insects.

Coragen may be subject to specific resistance management strategies. For further information refer to the Insecticide Resistance Management (IRM) section of this label, contact your farm chemical supplier, consultant, local Department of Agriculture or Primary Industries, or local FMC Representative.

 

Insecticide Resistance Management

 

Coragen insecticide contains chlorantraniliprole, a Group 28 Insecticide.

Unless directed otherwise in the specific crop/insect sections of the label, the following practices are recommended to prevent or delay the development of insecticide resistance to Coragen and to Group 28 insecticides:

  • Apply Coragen or other Group 28 insecticides using a “window” approach to avoid exposure of consecutive insect pest generations to the same mode of action. Multiple successive applications of Coragen or other Group 28 insecticides are acceptable if they are used to treat a single insect generation.

  • Following a “window” of Coragen or other Group 28 insecticides, rotate to a “window” of applications of effective insecticides with a different mode of action.

The total exposure period of all “Group 28-active windows” applied throughout the crop 

  • cycle (from seedling to harvest) should not exceed 50% of the crop cycle.

  • Incorporate IPM techniques into the overall pest management program.

  • Monitor insect populations for loss of field efficacy.

For additional information on insect resistance, modes of action and monitoring visit the Insecticide Resistance Action Committee (IRAC) on the web at http://www.irac-online.org

 

Mixing

 

Spray equipment must be clean and free of previous pesticide deposits before applying Coragen.  Fill spray tank to ¼ to ½ full of water.  Measure the amount of Coragen required for the area to be sprayed.  Add Coragen directly to the spray tank with the agitation engaged.  Mix thoroughly to disperse the insecticide.  Once dispersed, the material must be kept in suspension at all times by continuous agitation.  Use mechanical or hydraulic means, DO NOT use air agitation, premix or slurry.

If spray solution is left standing, ensure thorough re-agitation of the spray mix until fully resuspended.  DO NOT allow spray mix to sit overnight, as resuspension may be difficult.

 

The mixing sequence recommended is: water soluble bags, dry flowable or water dispersible granules, wettable powders, water based suspension concentrates (Coragen), water soluble concentrates, oil based suspension concentrates, emulsifiable concentrates, adjuvants and surfactants, soluble fertilisers and drift retardants.  Allow time for complete mixing and dispersion after addition of each product.

 

Compatibility

Since formulations may be changed and new ones introduced, it is recommended that users premix a small quantity of the desired tank mix and observe possible adverse changes (settling out, flocculation etc).  Avoid complex tank mixtures of several products or very concentrated spray mixtures.  Coragen is compatible with Captan, Dextrolac, Delan, Fulasin, mancozeb, Omite, Polyram and Systhane.

 

Surfactant/Wetting Agent

For Brassica vegetable, Brassica leafy vegetable, Stalk & Stem vegetables, Leafy vegetables, Lettuce, Fruiting vegetables (Cucurbits), Legume vegetables, Sweet corn use a non-ionic surfactant/wetting agent at 15 g active/100 L, (e.g. Agral 600 @ 25 mL/100 L).

 

DO NOT use BS1000 or Activator as it may cause crop phytotoxicity.

DO NOTadd a non-ionic surfactant/wetting agent if:

  • mixing with another product which already contains a surfactant and/or the product label advises not to add a surfactant.

  • mixing with a liquid fertiliser.

 

Application

 

Use enough water to ensure thorough coverage of the crop.  Adjust water volumes to crop stage.

A spray drift minimisation strategy should be employed at all times when applying this product.  The interaction of many equipment and weather-related factors determines the potential for spray drift.

Application equipment should be accurately calibrated to apply at least sixty (60) droplets per cm2 of target foliage.  Droplet VMD should be of MEDIUM spray quality according to ASAE S572 Standard or the BCPC guidelines.

 

APPLYING LARGER DROPLETS REDUCES DRIFT POTENTIAL, BUT WILL NOT PREVENT DRIFT IF APPLICATIONS ARE MADE IMPROPERLY OR UNDER UNFAVOURABLE ENVIRONMENTAL CONDITIONS.

Use high flow rate nozzles to apply the highest practical spray volume.  Nozzles with higher rated flows produce larger droplets.  Use the lower spray pressures recommended for the nozzle.  Higher pressure reduces droplet size, and DOES NOT improve canopy penetration.  WHEN HIGHER FLOW RATES ARE NEEDED, USE A HIGHER-CAPACITY NOZZLE INSTEAD OF INCREASING PRESSURE.  Use a nozzle type that is designed for the intended application.  With most nozzle types, narrower spray angles produce larger droplets.  Consider using low-drift nozzles.

 

Ground application

When applying Coragen by ground application apply in water volumes 200 – 1000 L/ha.

 

Aerial application (by fixed wing aircraft or helicopter)

Apply a minimum total spray volume of 40 L/ha with appropriate nozzles (e.g. Micronaire rotary atomisers, CP nozzles or conventional hydraulic nozzles).  DO NOT apply Coragen using Ultra Low Volume (ULV) methods.

 

Restraints

 

DO NOT apply if rainfall is expected within 2 hours of application.

DO NOT use on container or hydroponic grown crops.

 

SPRAY DRIFT RESTRAINTS

DO NOT apply with spray droplets smaller than a MEDIUM spray droplet size category according to nozzle manufacture specifications that refer to ASAE S572 Standard or the BCPC guidelines.

DO NOT apply when wind speed is less than 3 or more than 20 kilometres per hour at the application site.

DO NOT apply during surface temperature inversion conditions at the application site.

 

Users of this product MUST make an accurate written record of the details of each spray application within 24 hours following application and KEEP this record for a minimum of 2 years.
