Fall armyworm

Fall armyworm portal

Fall armyworm (FAW), Spodoptera frugiperda, arrived on mainland Australia in February 2020.

Since then, FAW has established populations in northern areas of Queensland, the Northern Territory and Western Australia. The movement of FAW is being monitored with movement into more southerly areas expected during warmer months through spring, summer and autumn.

Early indications are that maize and sorghum broadacre crops are a preferred food source for FAW, but it has also been found in some pulses. Potential impacts of FAW on crops grown in more southerly areas and its seasonal migratory range are not yet fully understood.

Growers and advisers should monitor industry updates on the migratory movement of FAW. Regular monitoring of crops to identify signs of early FAW infestation and implementing approved control measures is the best way of minimising economic losses caused by this pest.

This portal provides access to important information for Australian grain growers, including the national Fall Armyworm Continuity Plan – a reference document that consolidates information about FAW and its management in grain crops.

If you suspect FAW is present in your region, report it immediately to the Exotic Plant Pest Hotline on 1800 084 881.

The hotline will connect you to the responsible authority in your state or territory. Reporting the presence of FAW will assist in the response effort.

  • Permits

    Insecticides will remain an important part of an IPM program, together with biological control and good agronomic practices. Consult relevant thresholds following the FITE principles; Find, Identify, Thresholds, Enact.

    This table summarises APVMA permits for the control of Fall Armyworm (Spodoptera frugiperda) in grain crops. While this list will be updated when new permits are approved, permit approvals can and do change regularly. The current permit must be consulted and the approved use pattern followed. To access available permits consult the APVMA’s permit portal and search for ‘fall armyworm’ with the ‘pest/purpose’ button checked.

    Existing options are not covered on this page. Some insecticides may be registered in your crop for the control of other Armyworm, Lepidoptera or Helicoverpa species and may provide incidental control of fall armyworm. (read notes at the bottom of this page)

    Efficacy against Fall Armyworm in situations not addressed by the below permits has not been considered by the APVMA and may prove to be ineffective. For further information contact the product manufacturer or your local agronomic advisor.

    Whilst care has been exercised in the development of this guidance, users should ensure that they seek their own advice in relation to the use of insecticides, the effect of the relevant APVMA permit/s, and operation of the relevant State or Territory control of use legislation.

    Internationally developed action thresholds are likely to provide the best guidance until locally developed thresholds become available. Late season crops may experience higher pest pressure as the FAW population builds.

    If chemical intervention is required, other pests (e.g. Helicoverpa, mites, aphids) might be incidentally exposed and growers should consider the implications of insecticide resistance management and the impact on natural enemies.

    Read the Croplife resistance management guidance for fall armyworm.

    Natural enemies, including egg and larval parasitoids and predators, are likely to be important in suppressing FAW populations. FAW is in the same family (Noctuidae) as many other lepidopteran pests of field crops e.g. loopers, Helicoverpa, cutworm and other armyworms. All these pests are attacked by various egg, larval and pupal parasitoids, predators, and diseases.

    Pesticides and bee protection: In addition to following all the product label (and approved permit) directions, good communication between growers and beekeepers on a local level can assist greatly in managing potential risk to bees. The online tool BeeConnected helps to facilitate this communication by connecting registered beekeepers with registered farmers and contractors, enabling two-way communication on the location of hives and crop protection activities.

    Notes:
    At the time of developing this guidance, it is understood that:
    i) current State and Northern Territory control of use legislation permit use of a product in a specified crop or situation to deliberately target pests that are not listed for control in that crop or situation. However, this is subject to all label Directions for Use being followed including; crop, rate, timing, withholding periods to harvest and grazing along with all ‘DO NOT’ constraint statements. Control of non-listed pests may still be ineffective.
    ii) it is an offence in the Australian Capital Territory (ACT) to use any product for a pest that is not listed on the product label.
