In Southeast Queensland, agriculture is essential to the region’s economy and community, yet noxious weeds in Queensland threaten both crop yields and livestock productivity. Invasive species like lantana, fireweed, and giant rat’s tailgrass disrupt ecosystems, poison livestock, and drive up farm management costs.
According to the Queensland Government, weed management costs the state’s agricultural sector over $600 million annually, with a significant portion stemming from noxious weeds that dominate landscapes and reduce the quality of grazing land.
Precision agriculture and advanced drone technology offer modern solutions to these challenges, empowering farmers to tackle infestations with accuracy, reducing the need for excessive chemical use, and protecting Queensland’s agricultural heritage.
Lantana (Lantana camara)
Description
Lantana camara, a sprawling shrub originating from South America, has become one of the most troublesome noxious weeds in Queensland. Known for its vibrant flowers, lantana quickly spreads through natural and agricultural areas, creating dense thickets that outcompete native vegetation. These thickets restrict plant diversity and make land management increasingly challenging. In regions across Southeast Queensland, lantana dominates, reducing access to grazing land and creating physical barriers that disrupt farm operations.
Impact
- Environmental Impact:
Lantana poses a severe ecological threat as it invades bushland and pastures, forming dense mats that prevent sunlight from reaching native ground-cover plants. By creating a monoculture, lantana reduces biodiversity, eliminating habitats for native wildlife. The thick, tangled shrub is difficult for animals to navigate, and its aggressive spread is often detrimental to Queensland’s unique flora and fauna.
- Economic Impact:
Lantana is not just an environmental problem but also a significant concern among noxious weeds in Queensland due to its economic impact. Biosecurity Queensland estimates that lantana costs the agricultural sector millions of dollars annually, largely due to its impact on grazing land. The dense growth reduces the land available for livestock, limiting grazing options and choking out more beneficial plants. The costs associated with managing lantana infestations, including labour and herbicide expenses, add further financial strain on Queensland’s farmers. - Toxicity to Livestock:
Lantana contains toxic compounds, primarily affecting cattle and sometimes other livestock. Ingestion can lead to lantana poisoning, which causes photosensitivity, liver damage, and in severe cases, death. This toxicity poses a significant risk to cattle producers, where accidental ingestion can lead to substantial economic losses due to veterinary costs and decreased productivity in affected animals.
Control Methods
- Manual Removal:
While manually removing lantana can be effective for smaller infestations, it is highly labour-intensive. Cutting down and uprooting lantana may prevent regrowth, but the method requires significant manpower and time. For large infestations, manual control becomes impractical without supplementary strategies. - Chemical Control:
Herbicides can be applied to lantana to kill it effectively. However, chemical control requires careful application to avoid damage to surrounding native plants. Blanket spraying can impact non-target species, so precision is crucial. This method works best when combined with targeted application approaches, especially in environmentally sensitive areas. - Precision Drone Spraying:
Precision Ag Services offers an innovative solution for managing lantana infestations through drone technology. Our drones are equipped to apply herbicides with centimetre-level accuracy, targeting lantana thickets while leaving surrounding native vegetation untouched.

Fireweed (Senecio madagascariensis)
Description
Fireweed, a short, hardy plant with distinctive yellow flowers originally from Madagascar, has become one of the most problematic noxious weeds in Queensland. This invasive species thrives in grazing lands across Southeast Queensland, spreading aggressively and overtaking valuable pasture grasses. Due to its prolific seeding and resilience, fireweed can rapidly infest large areas, creating serious challenges for farmers and land managers. It is particularly concerning because it competes with grasses that livestock rely on, impacting both the quality and quantity of available grazing land.
Impact
- Threat to Livestock:
Fireweed contains toxic alkaloids that are harmful to livestock, especially cattle and horses. When ingested, these alkaloids can cause chronic liver damage, and in severe cases, even death. Fireweed poisoning in livestock can result in symptoms such as weight loss, lethargy, and photosensitivity. For farmers, this toxicity poses a substantial risk, leading to significant financial losses in both veterinary expenses and lost productivity. In Southeast Queensland, where cattle and other livestock are vital to the agricultural economy, fireweed’s toxicity represents an ongoing threat. - Costly to Manage:
Managing fireweed infestations is both challenging and costly. With the plant now affecting over 15,000 hectares in Southeast Queensland, controlling its spread requires persistent attention and resources. Without timely intervention, fireweed’s rapid growth and extensive seed dispersal can allow it to dominate pastures, reducing grazing capacity and forcing farmers to invest in control measures year after year. The reduction in grazing capacity can impact livestock health and farm profitability, as farmers may need to supplement feed or seek alternative pastures.
Control Methods
- Early Detection and Manual Removal:
Spotting and removing small patches of fireweed early in the season is one of the most effective ways to prevent its spread. By catching infestations in their early stages, farmers can avoid the need for larger-scale interventions. Manual removal, though labour-intensive, is feasible for smaller patches and can help reduce seed dispersal if completed before the plants flower and set seed. - Herbicide Application:
For larger infestations, targeted herbicide application can be an effective means of controlling fireweed. However, this method requires precision to ensure that herbicides do not impact non-invasive species or beneficial pasture grasses. Broad-spectrum spraying can cause collateral damage to the environment, so it’s essential that herbicides are applied with accuracy. - Drone Mapping and Spot-Spraying:
Precision Ag Services offers an innovative approach to fireweed management through drone mapping and spot-spraying. Our drones are equipped with advanced aerial mapping technology that accurately identifies areas infested with fireweed, allowing for highly targeted herbicide applications.
By focusing only on the affected areas, drone-assisted spraying reduces the need for large-scale chemical usage, minimises the environmental footprint, and protects surrounding native and pasture species. This approach ensures effective fireweed control while maintaining a balanced ecosystem, providing a sustainable solution for Southeast Queensland’s agriculture.
Effective fireweed management is crucial for protecting Southeast Queensland’s grazing lands and livestock. With the support of advanced technologies like those provided by Precision Ag Services, farmers can better manage fireweed infestations, reducing their costs and securing the health of their livestock and pastures.
Giant Rat’s Tailgrass (Sporobolus pyramidalis and Sporobolus natalensis)
Description
Giant rat’s tailgrass (GRT) is a highly invasive clumping grass species native to Africa, posing a severe threat to pastures across Southeast Queensland. Growing up to 1.5 metres in height, GRT forms dense, unpalatable patches that outcompete other pasture grasses, effectively rendering infested areas unusable for grazing. Its aggressive growth and dense structure make it particularly difficult to control, as it spreads rapidly and forms resilient root systems that are challenging to remove.
Impact
- Reduced Grazing Capacity:
GRT is unpalatable to livestock, meaning that cattle and other grazing animals avoid it, leading to decreased use of infested land. This grass dominates pastures, lowering the overall quality of grazing options. In fact, studies have shown that when GRT infests just 50% of a pasture, it can reduce grazing capacity by up to 80%. This reduction in usable land forces farmers to seek alternative grazing options, impacting farm operations and increasing the need for supplemental feeding. - Cost to Farmers:
The economic impact of GRT on Southeast Queensland’s agricultural sector is significant. It is estimated that GRT costs cattle producers over $60 million annually in lost productivity and additional management efforts. Farmers must invest time and resources in controlling GRT, and the reduction in usable grazing land means lower overall productivity. Additionally, GRT can spread to neighbouring properties if left unmanaged, increasing the need for coordinated control efforts across regions.
Control Methods
- Manual and Mechanical Removal:
For small infestations, manual or mechanical removal of GRT can be effective. However, due to its resilient root system, removing GRT requires consistent monitoring and effort to ensure that regrowth does not occur. While this method can be useful in localised areas, it is labour-intensive and impractical for larger infestations. - Chemical Control:
Herbicide treatment is a common method used to control GRT, but applying herbicides precisely to dense GRT patches is challenging. When herbicides are applied indiscriminately, they can affect non-target species, impacting overall pasture quality. Targeted application is essential to avoid damaging beneficial grasses, which is why precision in herbicide delivery is critical in managing GRT effectively. - Drone-Assisted Spot Treatment:
Precision Ag Services offers an advanced solution for controlling GRT through drone-assisted spot treatment. Our drones are equipped with high-resolution imaging and mapping capabilities, allowing us to identify and target GRT patches accurately.
