General Instructions


Insecticide Resistance Warning


For insecticide resistance management, Orthene Xtra is a Group 1B insecticide. Some naturally occurring insect biotypes resistant to Orthene Xtra and other Group 1B insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Orthene Xtra or other Group 1B insecticides are used repeatedly. The effectiveness of Orthene Xtra on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Arvesta Corporation accepts no liability for any losses that may result from the failure of Orthene Xtra to control resistant insects.


The user should seek advice, and monitor the performance, and if the results are not in accordance with expectations, contact the manufacturer immediately. Apparent resistance however, should not be confused with poor application, coverage or timing techniques.

Orthene Xtra may be subject to specific resistance management strategies. For further information contact your local supplier, Arvesta Corporation representative or local agricultural department agronomist.


Export Of Treated Produce

Growers should note that MRLs or import tolerances do not exist in all markets for edible produce treated with Orthene Xtra Insecticide. If you are growing edible produce for export, please check with Arvesta Corporation for the latest information on MRLs and import tolerances BEFORE using Orthene Xtra Insecticide.




Add the required amount of Orthene Xtra Insecticide to the full volume of water in the spray or mixing tank with the agitator in operation. Ensure that the granules are completely dissolved before spraying.




Good pest control requires even, thorough coverage of the target area. Application should be made using appropriate spray equipment and sufficient water to provide adequate penetration and coverage. Equipment settings and water volume may need to vary, depending on the growth stage of the crop. Application Instructions for all crops excluding Macadamias and Bananas By Ground Where spray volume equals or exceeds 1000 L/ha use the appropriate Rate per 100 L water, as specified in the 'High Volume' column of the Directions for Use table. Where spray volume is less than 1000 L/ha use Rate per hectare, as specified in the 'Low Volume' column of the Directions for Use table.


Aerial application Apply in a minimum of 20 L of water per hectare, using the appropriate rate per hectare, as specified in the 'Low Volume' column of the Directions for Use table.


Application Instructions for Bananas

Refer to Critical Comments section of Directions for Use Table for full details on method of application.


Special Instructions for Macadamias


Dilute spraying

  • 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 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 100L 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

  • 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.


This mixing rate for concentrate spraying can then be calculated in the following way:




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 (i.e. 1500 L / 500 L = 3)


4. If the dilute label rate is 50g/100L, then the concentrate rate becomes 3 x 50, that is 150 g/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.


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



Orthene Xtra Insecticide may be mixed in the spray vat with Oxydul®. A mixture of Orthene Xtra Insecticide with other products may be ineffective or may cause serious damage and hence is not recommended.


Drift Warning


DO NOT apply in weather conditions, or from spraying equipment, which could be expected to cause spray to drift onto adjacent crops, crop lands, pasture or livestock.


Protection of wildlife, fish, crustaceans and environment

DO NOT contaminate streams, rivers or waterways with this product or the used container.


Protection of crop, native and other non-target plants

Bananas: Use as a bell injection or bunch spray during the wet season may result in some damage to banana hands.


Ornamentals: Orthene Xtra Insecticide may cause foliage damage to certain shrubs and trees, eg. crab apple, cotton wood, Lombardy poplar and American elm. DO NOT spray more than once every 28 days on carnations and chrysanthemums. Certain chrysanthemum varieties, eg. Showoff, Iceberg, Albatross, Bonnie Jean and Statesman have, on occasions, been damaged by Orthene Xtra Insecticide.


Safety Directions


Poisonous if absorbed by skin contact, inhaled or swallowed. Repeated minor exposure may have a cumulative poisoning effect. Will irritate the eyes. Avoid contact with eyes. Do not inhale dust or spray mist. Obtain an emergency supply of atropine tablets 0.6 mg. When opening the container, preparing spray and using the prepared spray, wear cotton overalls buttoned to the neck and wrist and washable hat, elbow-length PVC gloves and face shield. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each day's use, wash gloves, face shield, and contaminated clothing.



Store in the closed, original container in a dry, cool, well-ventilated area, out of direct sunlight.



Single rinse before disposal. Add rinsings to spray tank. Do not dispose of undiluted chemicals on site. 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.




Re-entry Period

Do not allow entry into, or perform agronomic practices in, treated areas until the spray deposits have dried. When prior entry is necessary, wear cotton overalls buttoned to the neck and wrist and elbow-length PVC gloves. Clothing must be laundered after each day's use. For glasshouses and other confined areas, do not re-enter until spray deposits have dried and area has been thoroughly ventilated.
