Looking at the New Industry Opportunities Behind Pet Safe Weed Killer

Switchgrass (Panicum virgatum) has become a high-value crop in recent years due to its role in bioenergy production, forage systems, and conservation planting. However, successful stand establishment and long-term productivity heavily rely on early and effective weed management. Annual grasses like crabgrass, foxtails, and barnyardgrass can severely outcompete young switchgrass seedlings, limiting biomass yields.

Quinclorac, a selective post-emergent herbicide, is widely used in turf and rice systems for its ability to control problematic grassy weeds. Increasingly, it is being evaluated and applied as a targeted herbicide in switchgrass fields to suppress weed pressure during the early growth stages.


What Is Quinclorac and How Does It Work?
Quinclorac is a synthetic auxin herbicide (HRAC Group 4) that mimics plant hormones to disrupt cell elongation and growth. Its mode of action leads to abnormal growth, tissue distortion, and ultimately weed death, particularly in emerged annual grasses and some broadleaf weeds.

Key Features:


Chemical name: 3,7-Dichloro-8-quinolinecarboxylic acid



Formulations: 75% WDG, 20% SC, 25% WP



Weed targets: Crabgrass (Digitaria spp.), foxtail (Setaria spp.), barnyardgrass (Echinochloa spp.), clover, bindweed



Residual activity: Up to several weeks in soil, offering extended suppression



Rainfast: 6–8 hours after application




Is Quinclorac Safe for Switchgrass Fields?
Yes—Quinclorac can be used in switchgrass systems under certain conditions, especially as a post-emergent herbicide targeting grassy weeds without harming established switchgrass stands.

Crop Selectivity:


Switchgrass shows moderate to good tolerance to Quinclorac once it reaches 3+ tillers.



It is not recommended during seedling emergence or early establishment (within 2–4 weeks after seeding).



Registered Uses:


In some regions, Quinclorac is used off-label or under research permit in native grassland restoration and switchgrass biofuel programs.



Always check with local extension offices and label guidance before field application.




When and How to Apply Quinclorac in Switchgrass Fields
Best Timing:


Post-emergent: Apply when switchgrass is established and weeds are at 2–4 leaf stage.



Avoid applications during early emergence or drought stress to minimize crop injury.



Recommended Application Rates:




Formulation
Rate per Acre
Carrier Volume




75% WDG
0.67–1.0 lbs
15–40 GPA (ground)


20% SC
1.5–2.0 pints
10–40 GPA






Always add a methylated seed oil (MSO) or nonionic surfactant (NIS) for improved weed uptake.



Quinclorac is often tank-mixed with broadleaf herbicides (e.g., 2,4-D) for broader spectrum control.

Follow re-entry and harvest intervals as indicated on the product label.




Frequently Asked Questions (FAQ)
Q1: Can I use Quinclorac on new switchgrass seedlings?
A: No. Wait until switchgrass is well established (typically 4–6 weeks post-planting) before applying.

Q2: Will Quinclorac control perennial grasses?
A: No. It is effective on annual grassy weeds, not perennials like johnsongrass or brome.

Q3: Can I tank mix Quinclorac with 2,4-D?
A: Yes, in many cases, this is recommended to broaden control spectrum. Always conduct a jar test and read both labels for compatibility.

Q4: Is Quinclorac safe near waterways or sensitive plants?
A: Like most herbicides, avoid drift to non-target species and buffer zones near aquatic areas.

Why Woody Weed Control Matters
Woody weeds are more than just unsightly plants—they are aggressive, fast-spreading invaders that can seriously degrade pasture productivity, increase fire risk, and compromise land value. For growers, landowners, and pastoral managers, failing to control woody weeds early can result in costly infestations that are difficult and expensive to reverse.

What makes woody weeds particularly challenging is their resilience. These are not soft annuals you can pull by hand—they include hard-stemmed shrubs, vines, and small trees that regenerate from deep roots, woody crowns, or even stem fragments. Once established, they outcompete desirable forage species, restrict livestock access, and often provide cover for wild animals that damage infrastructure or native biodiversity.

In regions with variable rainfall or poor soil structure, woody weeds such as prickly acacia, lantana, blackberry, and willow often dominate the landscape if left unmanaged. Their spread is rapid, and many are now classified as noxious or invasive under national or regional weed control legislation, requiring active management by landowners and local authorities.

From a regulatory, economic, and environmental standpoint, it’s clear that controlling woody weeds is not optional—it’s essential. And among all control measures, herbicide-based strategies remain the most effective and scalable solution, especially when integrated into a planned weed management program.



What Are Woody Weeds?
Woody weeds are a diverse group of shrubs, vines, and small trees that share one common trait: they develop woody stems or branches that make them harder to control than typical broadleaf or grassy weeds. These species may be native or introduced, but in all cases, they have become aggressive competitors in pastures, rangelands, and natural ecosystems.

From a weed management perspective, woody weeds often fall under several formal classifications:



Invasive Species – plants introduced from other regions that spread rapidly and threaten local biodiversity



Noxious Weeds – legally regulated weeds that landowners are required to control



Weeds of National Significance (WoNS) – species ranked by governments for their high impact, such as lantana, bitou bush, and prickly acacia



Environmental Alert List Species – early-stage invaders with the potential to become major threats if left unmanaged



Common woody weeds across pastures and agricultural lands include:



Prickly Acacia (Vachellia nilotica)



Lantana (Lantana camara)



Blackberry (Rubus fruticosus complex)



Willow (Salix spp.)



Bracken Fern, Ragwort, Thistle



These plants are not only tough but persistent. They reproduce through seeds, root suckers, or stem fragments, thrive in both dry and humid climates, and often develop resistance to mechanical removal. Their dense canopies shade out grasses, and their thick stems resist mowing or grazing. Many also have defensive traits like thorns or toxins, which limit livestock access and make physical control hazardous or impractical.

This is precisely why herbicide use becomes a necessity—not just a convenience. Manual or grazing-based approaches are rarely enough to achieve long-term suppression. If you're managing large properties, roadways, or mixed-use areas, your choice of herbicide formulation and application method will determine your success in reclaiming infested land.

How to Identify Woody Weeds on Your Land
Accurate identification is the first step in any successful weed management program. With woody weeds, early detection is especially important—the younger the plant, the more effective herbicide treatment tends to be, and the lower the cost of control.

Woody weeds vary widely in appearance, but they typically share a few defining characteristics:

1. Wood-like Structure
Woody weeds, true to their name, develop rigid stems or branches that do not die back each year. Whether they appear as spreading shrubs, upright saplings, or thorny vines, their hardened structure enables them to persist through drought, fire, or grazing pressure.

2. Perennial Growth Habit
Most woody weeds are perennials—they live for several seasons, and some may take years to reach maturity. During this time, they establish deep root systems or woody crowns that allow regrowth even after slashing or partial removal.

3. Invasive Growth Pattern
Woody weeds often colonize disturbed or overgrazed areas, roadsides, fencelines, or waterways. They tend to grow rapidly and spread outward, forming dense thickets that choke out native grasses and reduce forage accessibility.

4. Reproduction by Seeds and Suckers
Many woody weeds produce high volumes of seed, which are spread by wind, animals, or water. Others propagate vegetatively through suckers, rhizomes, or root fragments, which makes mechanical removal less effective and favors chemical intervention.

5. Visual Indicators to Watch For





Feature
Clue to Woody Weed Presence




Thorny branches
Possible prickly acacia, blackberry, or thistle


Dense, low-growing mass
Indicative of lantana or bitou bush


Vine-like stems
Suggests scrambling woody weeds like wild rose


Unusual leaf texture
Waxy, hairy, or leathery leaves resist wetting




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. Your choice of active ingredient should reflect not only the target species but also the application method, site conditions, and whether residual control is needed.

How to Get Rid of Invasive Broadleaf Weeds Without Damaging Pastures
Weeds are more than just an eyesore—they represent a growing economic and ecological burden for landowners, especially in grazing and mixed farming systems. Among the most persistent and damaging are broadleaf weeds, a category of fast-growing, deep-rooted invaders that compete aggressively with desirable pasture species. If left unmanaged, they quickly spread across paddocks, reduce carrying capacity, and drive up the cost of land maintenance.

For livestock producers, the impact is even more severe. Broadleaf weeds can smother pasture in early spring, limit access to feed, and interfere with movement and grazing behavior. In severe cases, some species are toxic to livestock or contaminate hay and silage. As these weeds mature, they often become harder to kill, requiring more labor-intensive methods or repeated treatment.

The most effective way to stop this cycle is by combining early detection with the right herbicide strategy. At POMAIS, we help farmers, land managers, and agrochemical distributors select targeted broadleaf weed control solutions—backed by proven actives, multiple formulation options, and support for custom packaging and documentation. Whether you're managing 50 acres or 5,000, the earlier you act, the easier and more cost-effective control becomes.

What Are Broadleaf Weeds and Why Are They Hard to Control?
Broadleaf weeds are a diverse group of non-grass plants that grow in pastures, cropland, and disturbed areas. Unlike grasses, these weeds typically have wide leaves, branching stems, and deep root systems that allow them to survive harsh conditions and outcompete desired species. Common examples include thistles, docks, ragwort, chickweed, and capeweed—many of which are prolific seed producers and highly adaptable to different soil types.

What makes broadleaf weeds especially difficult to manage is their ability to regenerate from root fragments, produce thousands of seeds per plant, and grow rapidly during periods of seasonal rainfall. Some species can even remain dormant in the seedbank for years, waiting for the right conditions to emerge. Once established, they are resistant to mowing, grazing, and general cultivation, often requiring repeated or systemic intervention to achieve long-term suppression.

Manual removal may work for small infestations, but is impractical at scale. Slashing or grazing may reduce above-ground growth temporarily, but rarely eliminate the plant. That’s why, in agricultural settings, the use of selective herbicides becomes essential—allowing targeted control of broadleaf species while preserving productive pasture and crop species.

In the next section, we’ll look at the risks of ignoring broadleaf weeds, and how delayed action can significantly raise costs and reduce land productivity.

The Cost of Inaction: What Happens If You Don’t Control Them
Delaying action on broadleaf weeds might seem harmless in the short term—but it often results in higher long-term costs, reduced pasture value, and irreversible degradation of your land. Many broadleaf species grow aggressively during early spring, forming dense mats or rosettes that crowd out young pasture seedlings and create a competitive barrier for sunlight, moisture, and nutrients. If left untreated, they quickly dominate, leaving little room for productive forage species to recover.

In livestock systems, unchecked weeds reduce carrying capacity and limit access to grazing zones. Species like thistles or dock may even cause direct harm—either by injuring livestock, contaminating wool and hay, or introducing toxins when consumed in bulk. Over time, paddock management becomes more difficult as weeds interfere with fencing, rotation, and water point access.

There is also the financial impact to consider:



More herbicide is needed to control mature infestations



Mechanical removal may be required if chemical options are no longer sufficient



Pasture recovery efforts—like reseeding—become more expensive



Weed seed spread to neighboring properties can result in reputational or legal liability



In many cases, the economic losses from just one season of uncontrolled spread far outweigh the investment in early-stage herbicide treatment. That’s why experienced land managers and distributors turn to selective, systemic herbicides that stop weeds at the root—before they escalate into a costly problem.

In the next section, we’ll explore how to identify the most common broadleaf weeds on your property—so you can take action early and apply the right product at the right time.

How to Identify the Major Broadleaf Weeds on Your Property
Effective weed control begins with proper identification. While all broadleaf weeds share certain traits—such as wide, flat leaves and non-grass growth habits—each species behaves differently in terms of spread, resilience, and herbicide sensitivity. Recognizing which species dominate your pastures or cropping areas will help you select the most effective herbicide and application strategy.

Here are some of the most commonly encountered broadleaf weeds in pasture and non-crop zones:






Weed Name
Visual Characteristics
Growth Habit
Impact




Scotch Thistle
Large, spiny rosettes; woolly leaves; purple flower heads
Biennial, erect, up to 2 m tall
Smothers pastures, restricts livestock movement


Capeweed
Low-growing rosettes with yellow daisy flowers
Annual; spring-dominant
Outcompetes young pasture; seed contamination


Ragwort
Serrated leaves, yellow cluster flowers
Biennial or perennial
Toxic to livestock; invasive in cool zones


Dock (Curly or Broadleaf)
Broad leaves with wavy or smooth margins
Perennial with deep taproots
Resists slashing; regrows from root fragments


Spear Thistle
Upright with branched stems; purple flower at the top
Biennial
Spiny stems deter grazing; prolific seed producer


Chickweed
Small leaves, white flowers; sprawling ground cover
Annual; thrives in damp conditions
Competes with pasture during autumn/winter




Some weeds are easily confused during early growth stages—particularly those with rosette formations. That’s why early-stage field scouting and photographic comparisons are essential, especially during early spring or post-rainfall emergence.



If you're unsure which species are affecting your paddocks, we recommend consulting with your agronomist or requesting identification support from our team. At POMAIS, we provide technical assistance and herbicide pairing recommendations based on specific weed species and pasture systems.

In the next section, we’ll cover why herbicides remain the most effective long-term solution—and how to choose the right mode of action for maximum control with minimal pasture damage.

The Best Way to Eliminate Broadleaf Weeds: Herbicide Application
While mowing, grazing, and cultivation may offer short-term suppression, herbicide application remains the most reliable and scalable method for controlling broadleaf weeds—especially when infestations are widespread or deeply rooted. Modern herbicide technology allows you to target weeds at specific growth stages, with minimal impact on desirable pasture or crop species.

There are two key application strategies depending on weed development:

1. Post-Emergent Herbicide Treatment


Applied to actively growing weeds during vegetative or early flowering stages



Most effective when the weed is metabolically active (e.g., spring or after rainfall)



Systemic herbicides like MCPA, clopyralid, or dicamba move through the plant to kill roots and shoots



Best used for Scotch thistle, ragwort, docks, and chickweed



2. Pre-Emergent or Residual Control


Applied to soil before weed germination or during seedling emergence



Useful in rotation breaks or in paddocks with repeated infestations



Herbicides like prodiamine or metsulfuron-methyl provide lasting soil activity, preventing seedling establishment



Ideal for seed-dominant species like capeweed or variegated thistle



Application timing, weather conditions, and water volume also play a critical role. Herbicides should be applied on dry, wind-free days, with enough carrier volume to ensure full leaf coverage. Adding a penetrant or surfactant is essential for waxy or hairy-leaved species like docks or mature thistles.

At POMAIS, we support your weed control program with a wide range of selective herbicide formulations, all available in bulk, ready-to-label OEM formats, and tailored for use across pastures, paddocks, and non-crop areas.

In the next section, we’ll introduce the most effective active ingredients for broadleaf weed control—backed by field-proven results.

In the next section, we’ll explore how and when to apply herbicides to maximize effectiveness while minimizing risk to pastures and animals.

Timing & Technique: When and How to Apply Herbicides
Even the most effective herbicide can fail if applied at the wrong time or with poor technique. To achieve full-season control of broadleaf weeds—without compromising pasture health or wasting chemical—you need to understand how timing, coverage, and carrier volume work together to drive success.

Best Timing for Application


Early Spring (Pre-Flowering Stage): Ideal for thistles, ragwort, and capeweed. Weeds are actively growing and more susceptible to systemic herbicides.



Post-Harvest (Late Summer/Early Autumn): Useful for targeting regrowth or biennial rosettes before winter dormancy.



Pre-Emergence (Before Germination): Apply residual herbicides like metsulfuron-methyl or aminopyralid when rain is expected and seedbed is bare.



After Rainfall: Soil moisture supports active plant metabolism, improving uptake of systemic products.



Application Techniques


High-Volume Foliar Spray: Ensure full leaf coverage to the point of runoff. Recommended for dense infestations or hard-to-wet species like docks.



Boom Spraying: Suitable for large pastures or cropping areas. Use flat fan nozzles and overlap spray patterns for uniform coverage.



Spot Spraying: Ideal for isolated patches. Use low pressure to avoid drift and add a wetting agent for tough, waxy leaves.



Cut-Stump or Basal Bark Application: For woody invaders or mature broadleaf perennials with deep taproots. Combine with diesel or oil-based carriers for better bark penetration.



Tank Mixing: Compatible active ingredients (e.g., 2,4-D + dicamba) can improve spectrum and reduce resistance risk. Always test compatibility before large-scale mixing.



Adjuvants & Penetrants
Adding a premium penetrant or non-ionic surfactant ensures herbicides stick to and enter tough-leafed or hairy weeds. For example, docks, spear thistles, and some woody weeds may repel spray droplets without a penetrant.

At POMAIS, we not only supply broad-spectrum herbicide formulations—we also guide our clients on tank mix ratios, spray volumes, nozzle types, and coverage strategies. Our aim is to help you achieve maximum efficacy with every application, whether you're managing 50 hectares or thousands of acres.

Next, we’ll look at how to integrate land management practices alongside herbicide use for more sustainable and cost-effective weed control.

Supporting Land Management Strategies
Herbicides are powerful tools, but they work best as part of a broader weed management system. By combining chemical control with sound land management practices, you not only enhance herbicide effectiveness, but also reduce weed pressure year after year.

Here are key strategies you can implement alongside herbicide use:

1. Pasture Competition
Maintaining dense, vigorous pasture is one of the best ways to suppress broadleaf weeds naturally. Healthy grasses crowd out weed seedlings, limit light to the soil surface, and reduce the available nutrients weeds need to establish.



Fertilize pastures strategically to encourage rapid recovery after spraying



Avoid overgrazing, which creates bare patches where weeds can take hold



Reseed thin or bare areas with competitive forage species



2. Paddock Rotation and Stock Management
Rotating stock allows pastures to rest and regenerate, improving grass density and reducing weed re-establishment. Well-managed rotation also helps distribute nutrient load and reduce high-traffic weed zones near water troughs or gateways.

3. Machinery and Hay Hygiene
Weed seeds often spread through machinery, vehicles, and contaminated hay.



Clean spray equipment, tractors, and harvesters between properties or paddocks



Inspect and avoid using hay from weed-infested areas



Isolate new stock in quarantine paddocks to avoid introducing seeds via manure



4. Timely Intervention
Monitor weed growth across the seasons and apply herbicides early, before flowering and seed production begin. Targeting weeds while they are young and vulnerable reduces the need for repeat treatments and protects overall pasture integrity.

By integrating these agronomic practices into your weed control program, you can improve long-term suppression and reduce reliance on chemical inputs over time.

At POMAIS, we assist our clients not just with herbicide supply, but also with strategy development, ensuring your investment delivers the highest possible return—both agronomically and economically.

Capeweed (Arctotheca calendula) is a fast-spreading annual broadleaf weed that poses a serious threat to pastures, cropping systems, and animal health across Australia and similar climates. Recognised by its distinct yellow daisy-like flowers and low-growing rosette, capeweed competes aggressively with pasture species, reduces forage availability, and in some conditions, becomes toxic due to nitrate accumulation.

If you're a distributor, agronomist, or livestock producer, understanding how to identify and control capeweed is vital to ensuring pasture productivity and safeguarding livestock health. At POMAIS, we support clients across agricultural sectors with registered herbicide formulations, expert guidance, and scalable solutions for weed control. This guide outlines practical strategies to help you manage capeweed effectively and professionally.


Weed Profile: What Makes Capeweed a Problem?
Capeweed is a winter-growing annual that germinates in autumn and dominates in spring if left unchecked. Key characteristics include:



Flat rosette with soft, lobed, hairy leaves



Bright yellow flowers with black centres



Shallow fibrous root system



Prolific seed production, capable of forming dense mats



Capeweed prefers disturbed soils, overgrazed pastures, and areas with low ground cover. In addition to reducing the palatability of forage, it accumulates nitrates and oxalates under certain soil and climate conditions, posing risks of poisoning to grazing animals such as sheep, cattle, and horses.


Best Practices for Capeweed Control
1. Early Identification and Timing
Capeweed control is most effective when applied at the seedling to rosette stage, typically from autumn to early winter. Once flowering begins, chemical control becomes less effective, and seed bank replenishment becomes likely.

2. Cultural and Grazing Management


Maintain competitive pasture species (e.g., ryegrass, clover) through appropriate fertilisation and reseeding.



Avoid overgrazing, which creates bare patches and allows capeweed to establish.



Use rotational grazing to maintain sward density and improve weed suppression.



3. Herbicide Control: Selective Chemical Solutions
The following active ingredients are commonly recommended for capeweed control in pastures and cropping systems:




Application Stage
Active Ingredient(s)
Formulation Type
Notes


Early post-emergent
MCPA
Amine/ester (EC/SL)
Selective for broadleaf weeds, safe for grasses


Post-emergent
Bromoxynil
EC or SC
Contact herbicide, ideal for younger weeds


Broader spectrum
MCPA + Bromoxynil
Mix formulation
Synergistic activity for heavy infestations


Cereal crops
Diflufenican
SC
Provides residual control, often mixed with MCPA


Non-crop/renovation
Glyphosate
SL
For knockdown prior to reseeding



Always follow product labels and rotate actives where possible to prevent herbicide resistance.

4. Integrated Control Programs
For high-pressure infestations or regions with long capeweed histories, integrate:



Pre-emergent herbicides in cropping rotations



Mechanical mowing/slashing prior to flowering



Reseeding programs post-suppression to restore desirable cover




Safety and Livestock Considerations
Capeweed toxicity increases under:



High nitrogen fertilisation



Stressful growing conditions (drought or frost)



Heavy grazing of young plants in early spring



Animals may exhibit symptoms of nitrate poisoning such as weakness, labored breathing, or sudden death. If pastures are dominated by capeweed, restrict grazing and consult a veterinarian.
