Complete Guide to Woody Weed Control

Why Identification Matters for Herbicide Use:
Different woody weeds respond to different active ingredients and application methods. For example, glyphosate may control young seedlings via foliar spray but will be far less effective on established multi-stemmed shrubs unless injected or cut-stump treated. On the other hand, tebuthiuron granules are excellent for controlling deep-rooted trees but unsuitable for use near desirable species.

Why You Need to Eliminate Woody Weeds Promptly

Delaying woody weed control not only allows these plants to spread unchecked—it directly reduces the productivity, safety, and value of your land. Whether you manage grazing pastures, cropping zones, or conservation areas, early and decisive intervention with the right herbicides can save years of labor, reduce compliance risks, and protect your agricultural return on investment.

1. Reduced Pasture Productivity

Woody weeds compete aggressively for water, nutrients, and sunlight, displacing valuable pasture species. In heavily infested fields, carrying capacity for livestock can drop significantly—sometimes by more than 50%. Over time, this means:

• Lower livestock stocking rates

• Uneven grazing patterns and underutilized forage

• Soil degradation due to bare ground under dense thickets

By applying systemic or residual herbicides early in the season, you can suppress regrowth and allow pasture grasses to re-establish before the next grazing cycle.

2. Increased Fire Risk

During dry seasons, many woody weeds—especially lantana, prickly acacia, and bracken fern—become highly flammable, creating natural fuel loads. Their thick structure holds heat, spreads flames quickly, and may endanger fencing, sheds, and surrounding vegetation.

Chemical control methods, such as basal bark or tebuthiuron granule applications, are effective in reducing woody biomass before it becomes a fire hazard—without disturbing the soil like mechanical clearing does.

3. Harbor for Pests and Vermin

Woody weed thickets provide ideal shelter for feral pigs, rabbits, and foxes, which pose a threat not only to crops and livestock but also to native wildlife. These areas are also difficult to inspect or manage, increasing labor time for fencing, pest control, and mustering.

Eradicating woody weeds helps remove these pest refuges. Combining brushcutting with cut-stump herbicide treatment or glyphosate injection delivers lasting results even in rugged or remote terrain.

4. Legal and Compliance Obligations

In many regions, landowners are legally required to control noxious or declared weeds. Failure to comply with weed legislation may lead to fines or restrictions on property usage. Regulatory agencies increasingly recognize herbicide-based strategies as the most practical and scalable form of compliance.

If you're distributing crop protection products, this creates a key market opportunity. By offering registered, locally compliant herbicide products with proven woody weed efficacy, you help your clients not only protect their land—but also meet their legal responsibilities.

5. Economic ROI of Early Control

Investing in herbicide-based control at the early stages of infestation can reduce total treatment costs by 40–70% over the long term. Compared to repeated mowing, burning, or slashing—which often cause regrowth—herbicides provide season-spanning residual control, reducing labor and retreatment frequency.

In the next section, we’ll explore the most effective methods available to control woody weeds—and how different herbicide application techniques suit different species and landscapes.

Most Effective Ways to Control Woody Weeds

Woody weeds present a unique challenge—they’re resilient, persistent, and often grow in difficult terrain. While multiple management strategies exist, no single method is universally effective. The most successful control programs are integrated, combining physical, cultural, and chemical approaches. Among these, herbicide-based strategies remain the most reliable, scalable, and cost-effective solution, particularly in agricultural and pastoral settings.

1. Physical and Cultural Methods (Limited Effectiveness Alone)

These methods may provide short-term results or be useful as a supplement to herbicide application:

• Slashing or mechanical cutting helps reduce above-ground biomass but often stimulates regrowth from rootstocks or lignotubers.

• Grazing by livestock (particularly goats) may suppress seedlings, but established woody weeds are usually avoided.

• Burning can clear dense infestations temporarily, but some species—such as lantana—may regenerate vigorously after fire.

• Cultivation may damage root systems, but risks spreading weed fragments or disturbing desirable pasture species.

Ultimately, these methods are best used in combination with herbicide treatments, which can target underground structures and prevent regrowth.

2. Herbicide-Based Control: The Most Effective Long-Term Solution

Chemical control offers the most flexible and sustainable approach, especially when tailored to:

• Weed species

• Plant maturity

• Site conditions

• Application equipment available

Herbicides can be selective or non-selective, applied to foliage, stems, soil, or stumps, and formulated as liquids, granules, gels, or capsules. When applied at the right time and using the correct technique, herbicides translocate through the plant, killing it from the inside out—something mechanical methods cannot achieve.

At POMAIS, we supply a full range of professional-grade herbicides designed specifically for woody weed control, including:

• Systemic foliar sprays for active regrowth

• Basal bark and cut-stump treatments for established stems

• Soil-applied granules for residual control in grazing land

• Encapsulated formulations for stem injection in hard-to-reach areas

We also support our partners with guidance on optimal use timing, tank-mix compatibility, and resistance management, ensuring long-term efficacy across multiple seasons.

Herbicide Application Techniques for Woody Weeds

Choosing the right herbicide is only half the solution—how you apply it plays an equally critical role in achieving successful and lasting woody weed control. Different application methods are suitable for different plant sizes, species, terrain types, and operational scales. At POMAIS, we help you match the most effective technique to your conditions, ensuring optimal uptake and minimal environmental impact.

1. Stem Injection (Including Capsule-Based Systems)

Best for: Large, established trees with hard bark (e.g., prickly acacia, Chinese apple)

• Method: Cut horizontal notches into the trunk using an axe or drill. Immediately inject or pour glyphosate-based herbicide into the wound to reach the sap stream.

• For enhanced safety and efficiency, use encapsulated herbicides (e.g., glyphosate 700g/kg capsules) with an injection gun system.

• Advantage: Minimizes herbicide drift and soil contamination; effective even in sensitive ecosystems.

2. Basal Bark Treatment

Best for: Young trees and saplings (≤5 cm diameter), multi-stemmed shrubs

• Method: Mix triclopyr or picloram with a carrier (e.g., diesel) and apply to the lower 30 cm of the trunk, covering the entire circumference.

• Use during active growing periods for best results.

• Avoid treating wet or fire-charred bark, which impedes penetration.

3. Cut-Stump Application

Best for: Woody weeds that have been freshly cut, particularly in re-clearing operations

• Method: Immediately after cutting the plant close to ground level, apply a systemic herbicide (e.g., glyphosate, triclopyr, aminopyralid) directly to the exposed surface.

• Prevents suckering or regrowth from the stump.

• Effective when mechanical removal is necessary but long-term suppression is still required.

4. Foliar Spraying (High-Volume Hand Spray)

Best for: Actively growing leafy woody weeds such as lantana or blackberry

• Method: Use a hand sprayer or knapsack to fully coat the leaf surface to the point of runoff.

• Add a premium penetrant or surfactant for waxy or hairy leaves.

• Works best when plants are not drought-stressed and foliage is lush.

5. Boom Spraying

Best for: Broadacre application in pastures or open fields with uniform weed distribution

• Method: Use fan-nozzle boom sprayers with overlapping coverage and even pressure control.

• Target seedling-stage infestations or emerging regrowth before stem lignification.

6. Granular or Pelletized Application

Best for: Long-term suppression of deep-rooted or regrowing woody weeds in grazing zones

• Method: Apply tebuthiuron or metsulfuron granules by hand, spreader, or aerial equipment.

• Once rainfall activates the pellet, herbicide moves into the root zone and is absorbed systemically.

• Advantage: Residual effect persists for 1–3 seasons; minimal labor once applied.

7. Herbicide Gel Application

Best for: Environmentally sensitive areas (e.g., national parks, urban buffer zones)

• Method: Apply gel herbicide (e.g., aminopyralid-based) directly to freshly cut stumps.

• Offers a non-spray alternative, ideal for use around water sources or native vegetation.

Choosing the Right Herbicide: What Works Best

Woody weeds vary widely in their structure, growth cycle, and resistance to environmental stress—so no single herbicide fits all scenarios.
