Herbicides
Herbicides are crucial agricultural tools that help farmers manage weed growth, ensuring crops have access to the water, nutrients, and sunlight they need to flourish without competition. In Australia, a variety of different herbicides are used in most agricultural enterprises, from intensive cropping systems to extensive broadacre farming.
At Specialist Sales, we offer a wide range of herbicides, including glyphosates and residual herbicides. Discover the most popular products from respected brands, including Roundup Herbicide, Amicide Advanced 700 Herbicide, Starane Advance Herbicide and Tussock Herbicide.

How herbicides are used in farming
Farmers in Australia use herbicides to ensure efficient, sustainable, and profitable operations. They’re essential for managing widespread weed problems in both intensive and broadacre farming systems.
Pre-emergent herbicides are often used before planting to provide early weed control, while selective post-emergent herbicides are applied to control specific weeds without damaging crops. Crop and herbicide rotation are standard practices used to reduce herbicide resistance risk.
Herbicides are also used in mixed farming operations that include livestock, or in livestock grazing-only operations.
Understanding the different types of herbicides
Herbicides are classified based on their mode of action, selectivity, residual nature in the soil, and application timing.
Some herbicides are selective, which means they target specific types of weeds whilst leaving crops unharmed. Others are non-selective and will kill most plant species they come into contact with. They can also be pre-emergent, applied before weeds germinate, or post-emergent, applied after weeds have sprouted.
The residual nature of a herbicide is also a key differentiator between products and active ingredients. Many herbicides have a residual effect in the soil, meaning they will remain active for an extended period after application to provide ongoing weed control. Unlike knockdown herbicides that kill existing weeds upon contact, residual herbicides work by forming a chemical barrier in the soil, targeting weed seeds as they germinate. Other herbicides do not offer any residual effects.
Herbicides may act through contact, affecting only the part of the plant they touch, or systemically, where they’re absorbed and move through the plant, effectively killing it from the inside.
What are the most common types of herbicides for farming?
While there are many different active ingredients found in herbicides, a few stand out as the most commonly used – and effective – solutions in farming settings. These include:
- Glyphosates: Found in common products like Roundup weedkiller, glyphosate is a non-selective herbicide that kills annual and perennial weeds. However, glyphosate can be used selectively in certain settings, like glyphosate-resistant crops.
- 2,4-D: 2,4-D is a selective herbicide that is particularly effective at controlling broadleaf weeds in crops and pastures.
- Metsulfuron methyl: This selective herbicide is another popular choice for eradicating broadleaf weeds, and works by impeding plant cell division.
- Dicamba: The active ingredient in products like Surefire, dicamba is used in agricultural settings to selectively address weeds (predominantly broadleaf weeds) in crops. It’s often paired with MCPA for better results.
- MCPA: MCPA (2-methyl-4-chlorophenoxyacetic acid) is another selective herbicide option, commonly used in conjunction with dicamba, to kill broadleaf weeds in crops and pastures.
Tips for using herbicides
When it comes to herbicides, responsible use is crucial. This includes following label directions and rotating herbicide modes of action. These strategies can help to mitigate resistance risk and protect environmental and soil health.
