There are thousands of species of weeds and many different ways to control them. This weed control course is ideal for land managers, farmers, gardeners, orchardists, market gardeners, landscapers, spray contractors or anyone involved with controlling weeds.
The Certificate of Weed Control will give you insights into effectively and efficiently using best practice techniques to control weeds. In this weed killer course, you will learn about the different types of weeds, chemical herbicides, and safe practices to eliminate them.
In this weed control course, you will also discover non-chemical weed control methods, and study how to increase productivity and reduce environmental impacts with correct weed management in both agricultural and horticultural settings.

Weeds of National Significance (WoNS)
When undertaking our weed control course, you will become familiar with Weeds of National Significance that have been identified by the Australian government based on their potential for spread, invasiveness and social, environmental and economic impacts. Here are some of the most common.
Originally from South Africa, Lycium ferocissimum can rapidly form impenetrable spiny thickets, reducing stock movement and also the land available for pasture.
Originally from South Africa, Asparagus aethiopicus has become a serious environmental weed in temperate to tropical climates. It smothers other plants, excludes desirable species, and also impacts native animals.
Originally from South America, Alternanthera philoxeroides clogs waterways, impedes water flow, limits light and oxygen, and restricts access to water for people and animals. It grows year-round in tropical to sub-tropical areas.
Originally from North Africa, Arabian peninsula and India, Tamarix aphylla is a fast growing tree with serious impacts along waterways in arid and semi-arid Australia. It is a threat to the pastoral and tourism industry and the riparian biodiversity of central Australia.
Originally from South Africa, Chrysanthemoides monilifera subsp. rotundata is an aggressive environmental weed. It actively invades coastal dune vegetation where in many cases totally eliminates native flora.
The Rubus fruticosus aggregate is a long-living, fast growing shrub that impacts forestry, agriculture and natural ecosystems. Physical and chemical control over time can help control blackberries, however, care is needed so as not to impact the fruit industry or the native species, Rubus.
Originally from Africa, Asparagus asparagoides is a highly invasive scrambling herb/vine that is destroying large areas of native vegetation in southern Australia.
Cytisus scoparius is a native plant of western, southern and central Europe that is highly invasive, and is one of the major weed threats in the alpine and sub-alpine areas of Australia. In agricultural situations. it can form dense strands which reduce grazing and provide habitat for pest animals.
Cabomba caroliniana is an aquatic herb that grows quickly and produces vast amounts of submerged plant material. Its spread has been assisted by the deliberate ‘seeding’ of waterways to ensure a wild supply for the aquarium trade.
Cat’s Claw Creeper
Native to Central America, the Caribbean and tropical South America, Dolichandra unguis-cati develops an extensive network of underground tubers that are very difficult to remove. It has the ability to completely smother native vegetation, and is particularly aggressive in south-eastern Queensland and north-eastern New South Wales.
Chilean Needle Grass
Originally from South America, Nassella neesiana is a highly invasive plant with serious impacts on the environment, agriculture and the economy. If animals are present in summer when the sharp flowering seeds are produced, these can injure and damage animals and therefore downgrade produce.
Senecio madagascariensis is an introduced weed that is evident in both arable country and rangelands. It can dominate pastures and is responsible for the slow growth, illness and poor conditioning of cattle and can also result in death.
Andropogon gayanus was introduced from tropical Africa and is a serious weed in northern Australia from Western Australia to Queensland. It has profound impacts on the nutrient and water availability in the soil, and during bush fires creates very intense fires that can kill trees and present a potential danger to properties and people.
Originally from Western Europe, Ulex europaeus can form dense impenetrable thickets that exclude domestic and native animals, and provide cover for feral animals such as foxes and rabbits.
Hymenachne amplexicaulis is a semi-aquatic grass that forms dense stands that reduce plant diversity and available habitat for native animals. It invades tropical waterways and wetlands and threatens large areas of northern Australia.
Originally from the Americas, Lantana camara threatens forestry, agriculture and pastoral production and the biodiversity of conservation areas.
Originally from South America, Anredera cordifolia is an aggressive climbing vine that smothers other shrubs and trees. It climbs over other plants and due to its weight, causes structural damage or the collapse of the canopy in tropical, sub-tropical and in warm to cool temperate areas.
Prosopis is one of four species of prickle bushes that have infestations scattered throughout semi-arid Australia. It is a nuisance in rangelands where it forms dense impenetrable strands, particularly around waterways.
Giant Sensitive Plant is native to tropical America and in the Top End of northern Australia more than 80,000 hectares of native wetland vegetation has been replaced by this plant.
Parkinsonia aculeata is a native plant of the Americas and forms dense prickly thickets along watercourses and makes land inaccessible. It is a threat to wetlands and rangelands and flood prone country is particularly susceptible.
Originally from the Americas, Parthenium hysterophorus is a toxic aggressive herb and is currently widespread in Queensland. It is toxic to humans and can cause severe dermatitis and respiratory problems. In animals, it can cause skin lesions, mouth ulcers, dermatitis and taint milk and meat.
Annona glabra is an aggressive invader of freshwater and brackish wetlands, rainforests, waterways, and coastal habitats in northern Queensland. It forms dense thickets that reduce biodiversity and threaten some rare species of flora and fauna.
Vachellia nilotica subsp. indica is native to India and Pakistan and is now a weed of national significance in semi-arid Australia. It is a thorny shrub or small tree that now covers large tracts of Queensland’s grasslands and infests watercourses and woodlands.
Originally from South America, Nassella trichotoma severely reduces the carrying capacity of land, and if animals are fed only on Serrated Tussock, the leaves can form balls in the rumen causing their loss of condition and eventual death.
