General Instructions



If the crop or pasture is to be cut for stockfeed, do not sell any stock that have been fed cut material for export slaughter until the Export Slaughter Interval (ESI) set below has been observed. The ESI is the minimum period that must elapse between removal of grazing livestock to clean pasture or clean feed and slaughter.



Observe the grazing withholding periods as specified above before grazing treated pastures or fodder crops or cutting them for stockfeed.


If over-spraying of grazing livestock is unavoidable and does occur, withhold stock from slaughter until the Export Grazing Interval (EGI) or Export Slaughter Interval is met. The EGI is the minimum period that must elapse between the application of the chemical product and slaughter of the stock, where grazing has continued on the crop/pasture from the time that the chemical product was applied.



The label withholding period for grazing only applies to stock slaughtered for the domestic market. Some export markets apply different standards. To meet these standards, ensure that the Export Slaughter Interval or the Export Grazing Interval is observed before stock are sold or slaughtered.



Observe the grazing or cutting for stockfeed withholding period specified above before grazing lactating dairy stock on treated pastures or fodder crops, or before cutting treated crops as feed for lactating dairy stock.



Livestock that have been grazing on or fed treated crops and/or over-sprayed should be placed on clean feed for 42 days (6 weeks) prior to export slaughter.



Livestock that have been grazing on treated crops/pastures and/or over-sprayed should not be sold for export slaughter for 56 days (8 weeks) after application of the chemical product, unless the Export Slaughter Interval has been observed.



Trojan may persist on dry pasture (or in harvested and stored animal feed, e.g. hay) for long periods. Livestock fed on pastures that were treated when drying off or while dry, may have residues at levels unacceptable to our overseas markets. Similarly, feeds harvested from pastures or crops treated when drying off or while dry, may have unacceptable levels of residues. The pasture, or crop, must be regarded as contaminated until such time as there has been substantial regrowth (i.e. following good rains or the Autumn break).

Livestock grazing or receiving contaminated feed should be managed in accordance with the Export Intervals described above. If further advice is required, contact your local State Department of Agriculture or Primary Industries, or the Australian Pesticides and Veterinary Medicines Authority (APVMA).


Insecticide Resistance Warning


For insecticide resistance management Trojan Insecticide is a Group 3A insecticide. Some naturally occurring insect biotypes resistance to Trojan Insecticide and other Group 3A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Trojan Insecticide or other Group 3A insecticides are used repeatedly. The effectiveness of Trojan Insecticide on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, FMC accepts no liability for any losses that may result from the failure of Trojan Insecticide to control insects.


Trojan Insecticide may be subject to specific resistance management strategies. For further information contact your local supplier, FMC representative or local agricultural department agronomist.


To help contain pyrethroid resistance in Helicoverpa (Heliothis) armigera in northern New South Wales and Queensland the summer Crop Insecticide Resistance Strategy published by the Avcare Insect Resistance Action Committee and the Cotton Industry Resistance Management program published by the Australian Cotton Cooperative Research Centre should be adhered to. Failure to observe these strategies may result in widespread resistance affecting the future viability of summer cropping. This product should NOT be used to treat infestations that were not controlled by an earlier application of Trojan or another synthetic pyrethroid. Infestations not controlled by this product should be treated with an insecticide from another chemical group.




For ground or aircraft application with water: Add the required quantity of Trojan Insecticide to water whilst under agitation to ensure thorough mixing. Agitate while spraying. Do not allow the mixed solution to stand longer than 24 hours before use. If using highly alkaline water spray immediately after mixing.


For cotton only add Trojan Insecticide last if mixing with Predator* 300 Insecticide, or Rescue* Insecticide. For Ultra Low Volume (ULV) oil based applications: Add the required quantity of Trojan Insecticide to the mineral spraying oil.


For Cotton only add the mineral spraying oil, if any is required, if mixing with Predator* 300 Insecticide or Rescue* Insecticide whilst under agitation to ensure thorough mixing. Add the required quantity of Trojan Insecticide last whilst thoroughly agitating. Agitate ULV solutions while spraying. Do not allow the mixed ULV solutions to stand longer than 24 hours before use.




Good coverage is essential to ensure adequate control. Trojan Insecticide may be applied by ground rig or aircraft using a FINE to MEDIUM spray as defined by the British Crop Protection Council system or the American Society of Agricultural Engineers (S572). For ground rigs apply Trojan Insecticide in 50-100 litres of water per ha. For aerial application apply Trojan Insecticide in at least 20 litres of water per ha. Trojan Insecticide may also be applied as an oil based ULV spray in a total spray volume of at least 5L/ha. ULV spraying is not recommended in areas where drift may cause concern.



Do not apply if rain is expected within 30 minutes.



Acceptable "threshold" values for eggs and larval numbers may vary according to the stage of crop development and the pest management program undertaken. Alternative higher thresholds may be acceptable under certain circumstances.



Trojan Insecticide is a contact and residual insecticide. If spraying frequency is based on scouting, then for Helicoverpa spp. application at egg hatch will give optimum results.


Crop Checking

Frequent and thorough checking of whole plants, terminals, squares, flowers, bolls or fruiting bodies as required, should be made over a random sample of plants, representative of the whole crop area.


Inspect crops after spraying to ensure a thorough kill has been obtained, however, maximum kill may not be achieved until 48 hours after treatment, then check at frequent intervals, not more than 2 days apart when insect pressure is heavy. Apply the recommended treatment as soon as a crop check indicates spraying is necessary.



Trojan Insecticide when applied as a water-based spray is compatible in mixture with Predator* 300 Insecticide, Rescue* Insecticide, Lorsban* 500 EC Insecticide and piperonyl butoxide (PBO) synergist.


Trojan Insecticide when used in an ULV application is compatible in mixture with Predator* 300 Insecticide, Rescue* Insecticide, PBO synergist, DC-Tron Cotton spraying oil, or a similar mineral spraying oil.


Protection of wildlife, fish, crustaceans and environment

Dangerous to fish and aquatic invertebrates. DO NOT contaminate streams, rivers or waterways with Trojan Insecticide or the used container. Tail waters which flow from treated areas should be prevented from entering river systems.

In case of spillage on floor or paved surfaces, soak up with sand, earth or synthetic absorbent and dispose of waste in a suitably licensed local authority landfill. If no landfill is available, bury the waste below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways.


A strategy to minimise spray drift must be employed at all times when applying sprays near sensitive areas such as natural water-bodies.


Safety Directions


Harmful if inhaled or swallowed.
