Herbicides in South Africa play a crucial role in managing weeds across agricultural, urban, and industrial settings. Understanding the different types, applications, and benefits of herbicides can help landowners and farmers make informed decisions about weed control.
Types of Herbicides in South Africa
Herbicides are categorized based on their selectivity, mode of action, and application timing.
1. Selective vs. Non-Selective Herbicides
- Selective Herbicides: Target specific weed species without harming desired plants.
- Non-Selective Herbicides: Kill all vegetation in the treated area, ideal for industrial sites and pathways.
Read more about selective and non-selective herbicides.
2. Residual vs. Non-Residual Herbicides
- Residual Herbicides: Stay active in the soil for an extended period, preventing weed regrowth.
- Non-Residual Herbicides: Work immediately upon application but do not offer long-term soil protection.
Learn about residual vs. non-residual herbicides.
3. Systemic vs. Contact Herbicides
- Systemic Herbicides: Absorbed by weeds and move within the plant to kill it completely.
- Contact Herbicides: Destroy only the parts of the plant they touch, requiring thorough application.

Applications of Herbicides in South Africa
1. Agriculture
Farmers use herbicides to control weeds that compete with crops for nutrients, water, and sunlight.
Common options include:
- Lumberjack Systemic Herbicide – Effective against grassy weeds.
- Versus Herbicide – Targets broadleaf weeds.
2. Urban Weed Control
Weed management in public spaces, sidewalks, and roadsides requires non-selective or systemic herbicides such as:
- Two-Step Systemic Herbicide – Designed for urban environments.
- Scuba Contact Herbicide – Effective against aquatic weeds.
Discover more about the benefits of herbicides in urban areas.
3. Industrial and Non-Crop Areas
Non-crop herbicides ensure weed-free railway tracks, power lines, and industrial zones.
Long-lasting solutions include:
- Bundu Long-Residual Herbicide – Controls weeds for extended periods.
- Kilo Non-Selective Granular Herbicide – A granular option for industrial sites.

The Role of Adjuvants in Herbicide Performance
Adjuvants enhance the efficiency of herbicides by improving spray coverage, absorption, and rainfastness.
Popular adjuvants include:
- Silwet Non-Ionic Organosilicone Adjuvant – Boosts herbicide penetration.
- Sprayfilm 10 Sticker and Spreader – Improves adhesion to plant surfaces.

Environmental and Safety Considerations
Using herbicides responsibly ensures environmental protection and user safety.
Best practices include:
- Choosing the Right Herbicide: Match the product to the target weed and location.
- Proper Application: Follow recommended rates and avoid spraying on windy days to reduce spray drift.
- Protecting Water Sources: Avoid contamination of nearby rivers and dams.
