Granular Herbicides

Granular Herbicides

Granular herbicides are an efficient, convenient way to control woody and noxious weeds, especially when applied using broadcast or spot treatment methods. They’re a popular formula because of their easy application and extended period of coverage, and unlike liquid options, they don’t carry a risk of drift onto desirable plants.

Why choose granular herbicides? 

Granular herbicides are used in Australian agricultural settings for several reasons. 

  • Targeted efficacy: Granular herbicides are selective, meaning they’re designed to specifically eradicate tough weeds whilst minimising impact on desirable plants (when applied correctly). 
  • Easy application: These formulations are easy to apply and spread, making them ideal for broadcast application in pastures or precise spot treatments. They don’t need to be mixed with water, and specialised spraying equipment is not required. 
  • Reduced risk of drift: Off-target drift can be problematic when using liquid herbicides, but this is minimised when using a granular alternative. 
  • Long-lasting action: Most granular herbicides offer residual control in the soil, slowly releasing active ingredients to prevent weed germination and growth over time.
  • Weather tolerance: These products are less susceptible to wash-off by rain immediately after application compared to foliar sprays, allowing for greater flexibility in application timing.
  • Compliance and safety: Specialist Sales’ granular herbicides meet Australian agricultural requirements. Refer to individual Product Labels for detailed safety instructions.

What are the key features of granular herbicides? 

There are a handful of characteristics that separate granular herbicides from other common herbicide formulations, such as foliar sprays and soil drenches. 

  • Active ingredients: Granular herbicides contain powerful active ingredients proven to disrupt the growth of woody and noxious weeds, resulting in plant death. 
  • Gradual release: Many products offer slow-release action to ensure long-term weed suppression and cut reapplication costs and labour. 
  • Selective action: Certain granular herbicides are selective, which allows for weed control without off-target damage. 
  • Good compatibility: Most granular herbicides are compatible with other products commonly used in an integrative weed management strategy. 

How are granular herbicides applied? 

There are three key ways to apply granular herbicides in agricultural settings: 

  • Aerial application: Application conducted using helicopters, drones, or planes in remote regions. 
  • Broadcast spreading: Distribution in larger areas like pastures with a hand-spreader or vehicle-mounted spreader. 
  • Spot treatment: Where granules are applied directly around the base of individual weeds or clumps of target plants. 

For detailed application instructions, refer to the Product Label. 

What are the best practices when using granular herbicides?

To ensure the efficacy of your chosen granular herbicide, follow these best practice tips: 

  • Timing: Apply during periods of active growth or when weeds are most susceptible – typically, before and after rain to allow for product activation and root uptake. 
  • Calibration: Ensure equipment is properly calibrated to ensure the correct dosage is delivered. 
  • Weather conditions: Only administer in calm conditions to avoid uneven distribution. Ensure that sufficient moisture (rainfall or irrigation) is received to activate the herbicide.
  • Environmental considerations: Be mindful of sensitive areas, waterways, and non-target plants. Select a product with low mobility in the soil if environmental impact is a concern. 
  • Monitoring: Regularly inspect treated areas to monitor efficacy and identify new growth.
