Australia’s diverse ecosystem is a point of pride for many, but it also makes the country a fertile ground for invasive species. These unwelcome guests can wreak havoc on local flora and fauna, and in some cases, they can become a significant nuisance for the average Australian homeowner.
When a pest infestation strikes, it can quickly turn a thriving lawn into a disaster zone. One gardener recently encountered a severe outbreak, with their garden overrun by relentless invaders. Determined to fight back, they discovered an effective way to protect their lawn and prevent further damage.
The invader in question is the fall armyworm, which has recently emerged as a formidable foe for gardeners and farmers alike.
The fall armyworm, a pest that has caused widespread agricultural destruction since its unwelcome arrival, has proven to be a resilient adversary. With its strong migratory capabilities, the moth can travel vast distances, and its voracious larvae have a broad diet that includes a variety of crops and weeds.
This adaptability has allowed the fall armyworm to establish itself as a major pest in the country, particularly in the warmer northern regions where it can reproduce year-round.
A Perth gardener’s battle with these pests highlights the challenges many Australians face in protecting their lawns and gardens. The woman recounted how her lawn was decimated within days by the fall armyworm, a plight she initially missed due to her busy work schedule.
Upon discovering the infestation, she turned to a surprisingly simple yet effective method to fight back: soapy water.
The soapy water trick, which involves spraying or dunking affected plants in a mild soap solution, disrupts the pests’ protective outer coating, leading to dehydration and death. This method, while seemingly unassuming, proved to be an eye-opener for the gardener as she witnessed the sheer number of grubs emerging from her lawn.
The Department of Primary Industries and Regional Development (DPIRD) in Western Australia has acknowledged the severity of the fall armyworm problem. The pest’s ability to survive harsh conditions and remain active across all seasons poses a continuous threat to agriculture and home gardens.
In response, DPIRD has been working with growers and researchers to develop sustainable and cost-effective solutions to mitigate the damage caused by these pests.
For those in the southern parts of Western Australia, there is a silver lining. The fall armyworm tends to die out during the winter months, providing a respite from its destructive activities. However, vigilance is key, as the pest is known to devastate crops by feeding on leaves, stems, and even the reproductive structures of plants.
DPIRD encourages residents to be proactive in identifying potential fall armyworm infestations.
‘Fall armyworm is easily confused with many other caterpillar pests so knowing your pest can help determine what approach will work best in your situation,’ said a DPIRD spokesperson.
The department has also made resources available, such as the MyPestGuide Reporter app and the Pest and Disease Information Service, to help homeowners and gardeners confirm the presence of the pest and determine the best course of action.
The fall armyworm’s success in the country is partly due to the absence of its natural predators, which are present in its native range. While some native predators do prey on the fall armyworm, they are not sufficient to control its population effectively.
While Australians cherish the country’s unique environment, it’s essential to remain aware of the threats posed by invasive species like the fall armyworm. By staying informed and taking proactive measures, you can protect your gardens and contribute to the health of your local ecosystems.
