Fall Armyworm
Fall Armyworm (FAW; Spodoptera frugiperda) is a destructive horticultural and field pest that was detected in Australia in 2020.
Detection and identification
FAW are known for their ability to devastate crops fast and reproduce several generations in a single season. Early detection is imperative in choosing an effective course of action to target egg and larval stages of the pest. The correct identification of FAW is critical to implementing control options to stop the pest, which can significantly damage plants and reduce crop yields.

Control measures
The timely implementation of control measures can successfully eradicate FAW, but it can be expensive. Consider whether the cost of using the amount of pesticides needed to stop the pest will be worth it financially. As there may be multiple infestations within a season, several treatments may be required. That cost could exceed the value of lost crop yield if no action is taken.
Consult with an experienced local agronomist familiar with FAW outbreaks before choosing biological or chemical control options.
