Glufosinate-Ammonium Herbicide

How POMAIS Glufosinate-Ammonium Works | Fast Action Through a Proven Biochemical Pathway

POMAIS Glufosinate-Ammonium Herbicide works by targeting a key enzyme in plant metabolism: glutamine synthetase. This enzyme is essential for two major plant processes—ammonia detoxification and glutamine synthesis. When this enzyme is blocked, toxic levels of ammonia quickly build up in the plant cells, leading to rapid cell damage, disruption of photosynthesis, and ultimately plant death.

Unlike systemic herbicides like glyphosate, glufosinate works through a contact-action mechanism. After foliar application, it is absorbed by the leaves and stems, moves locally through the plant tissue, and begins to act within hours.

Key Action Timeline:

• 2–6 hours after application: Photosynthesis begins to shut down
• Within 1 day: Plant growth stops entirely
• 2–3 days: Chlorosis (yellowing) and necrosis (browning) begin to show
• 7–14 days: Complete death of the treated weed
• 25–45 days: Residual control period, depending on weather and weed pressure

Glufosinate is rainfast within 4 hours of application, making it a reliable tool even in humid or unpredictable climates. Additionally, once glufosinate reaches the soil, it binds tightly and degrades quickly through microbial action—meaning it does not harm crop roots or leach into groundwater.

Why It Matters for Your Customers

• Rapid visible results: Users can see yellowing in 48 hours—confidence that it’s working
• Contact + residual effect: Eliminates existing weeds and prevents regrowth for weeks
• Environmental compatibility: Biodegradable in soil, low risk to water systems
• Low resistance risk: Targets a different site of action than glyphosate (Group 10 vs. Group 9), ideal for rotation

The fast-acting, contact-kill nature of POMAIS glufosinate herbicide makes it especially effective in orchards, vineyards, and post-emergence weed control programs where quick burndown is needed without soil carryover risk.

Fast and Visible Results | What to Expect After Using POMAIS Glufosinate-Ammonium

One of the key advantages of POMAIS Glufosinate-Ammonium Herbicide is its rapid effect on target weeds. Users can visually confirm that the product is working within days of application, which helps avoid unnecessary re-spraying and builds confidence in field performance.

What Happens After Application?

Time After Spraying	Visible Effects
2 to 6 hours	Photosynthesis slows down; energy production stops in weed tissues
1 day	Weeds stop growing completely
2 to 3 days	Leaves begin to turn yellow (chlorosis), edges curl or dry out
4 to 7 days	Tissue death begins (necrosis), browning spreads across leaves and stems
7 to 14 days	Full plant collapse and death, even in perennial weeds

The speed of these effects may vary depending on:

• Weather conditions (warm temperatures speed up the process)
• Weed type and size (young weeds respond faster)
• Spray coverage quality (uniform application gives better results)

Rainfastness: Is It Safe If It Rains?

Yes—POMAIS Glufosinate-Ammonium is rainfast within 4 hours under normal conditions.

This means:

• If it rains 4 hours or more after spraying, you can expect full herbicidal performance
• If rain occurs within 1–2 hours, some product may wash off, and partial re-treatment may be needed depending on coverage

Tips to Maximize Rainfastness:

• Apply during calm, dry weather with no rain forecast for 6–8 hours
• Use correct water volume (200–300 L/ha) for optimal leaf coverage
• Avoid spraying on heavily dew-covered plants early in the morning

Key User Benefits

• Confidence in visible results within 2–3 days
• Faster field turnaround for follow-up operations
• Stable control even with variable weather, thanks to rapid uptake into plant tissue
• Efficient use of product, reducing waste and re-spray costs

With POMAIS Glufosinate-Ammonium, farmers can rely on fast knockdown and predictable weed control performance—even under uncertain weather conditions.

Crop and Environmental Safety | Clean Results Without Long-Term Harm

POMAIS Glufosinate-Ammonium Herbicide is designed to deliver effective weed control while minimizing long-term impact on crops, people, and the environment. Our product is manufactured to meet both agronomic performance and regulatory safety standards, making it a reliable solution for integrated weed management programs.

Crop Safety

While Glufosinate-Ammonium is a non-selective herbicide, it is safe for use in:

• Glufosinate-tolerant crops (e.g., LibertyLink soybeans, cotton, and corn)
• Tree crops and vineyards when used as directed or shielded sprays
• Non-crop areas and field borders where weed competition needs to be eliminated

Important Note:
Glufosinate must not be sprayed on the foliage of non-tolerant crops, as it will cause visible leaf burn and growth inhibition. For orchard and vineyard use, apply between rows only, avoiding contact with leaves or stems of young trees or vines.

Soil and Groundwater Safety

Once applied, Glufosinate binds tightly to the soil surface and breaks down quickly through microbial activity. It has:

• Low mobility in most soil types
• No significant leaching to groundwater
• No long-term residue that could affect future planting or rotational crops

This makes it particularly well-suited for use in permanent cropping systems, drip-irrigated orchards, and environmentally sensitive zones.

Human and Animal Safety

POMAIS Glufosinate-Ammonium is classified as low in mammalian toxicity. When used according to label instructions, it is safe for farmers, workers, and nearby communities.

Safety measures during handling:

• Wear gloves, goggles, and protective clothing during mixing and application
• Avoid direct inhalation of spray mist
• Wash hands and exposed skin thoroughly after use

No re-entry interval is typically required once the spray has dried, but local safety standards should always be followed.

Bee, Fish, and Wildlife Safety

• Low risk to bees when applied in the early morning or late evening
• Not harmful to birds or beneficial insects
• Avoid direct application near surface water—as with all herbicides, spray buffer zones are recommended

With proper application, POMAIS Glufosinate-Ammonium ensures strong field performance while maintaining compliance with global environmental safety standards.

Resistance Management | Your Solution Against Glyphosate-Resistant Weeds

As herbicide resistance continues to challenge modern agriculture, POMAIS Glufosinate-Ammonium Herbicide plays a vital role in diversified weed control strategies. It is especially useful in fields where glyphosate-resistant weeds have become dominant, providing an alternative site of action that targets those difficult populations.

Why Resistance Management Matters

Overuse of a single herbicide—particularly glyphosate (Group 9)—has led to the rise of resistant weed species like:

• Amaranthus spp. (pigweed, Palmer amaranth, waterhemp)
• Conyza spp. (marestail, horseweed)
• Lolium spp. (annual ryegrass)
• Ambrosia spp. (ragweed)

These weeds can survive normal glyphosate treatments, spread quickly, and cause significant yield loss.

Glufosinate: A Different Mode of Action

Glufosinate belongs to HRAC Group 10 (inhibitors of glutamine synthetase). Its unique mode of action allows it to:

• Control weeds that glyphosate can no longer kill
• Delay resistance development when used in rotation or tank mixes
• Preserve the long-term value of other herbicides in your program

Because it works via contact action, it complements systemic herbicides (like glyphosate or dicamba) in sequential or combined applications.

How to Integrate Glufosinate into a Resistance Program

Strategy	Description
Rotation	Alternate Glufosinate with other herbicide classes (Group 2, 4, 14) season by season or crop by crop
Tank Mixing	Mix Glufosinate with other post-emergent herbicides to hit weeds with multiple modes of action
Sequential Spray	Use Glufosinate after pre-emergent herbicides to eliminate escapes
Use in GM Crops	Deploy Glufosinate-tolerant crops (e.g., LibertyLink soybeans) to widen post-emergent control options

POMAIS Combination Products for Resistance Programs

We also offer custom formulations designed to enhance spectrum and reduce resistance risks:

• Glufosinate-Ammonium + Glyphosate
• Glufosinate-Ammonium + Atrazine
• Glufosinate-Ammonium + Flumioxazin / Dicamba / MCPA

These ready-to-use blends allow distributors to offer complete resistance-fighting solutions, especially in no-till or conservation farming systems.

If you’re building a long-term herbicide rotation program, POMAIS Glufosinate-Ammonium is an essential component to maintain control, avoid yield loss, and support sustainable farming.

Usage Tips & Common Mistakes | Maximize Performance with POMAIS Glufosinate-Ammonium

To get the best results from POMAIS Glufosinate-Ammonium Herbicide, proper application is critical. While this product is powerful and reliable, its effectiveness can drop sharply if misused. Below are key recommendations and reminders based on field experience and feedback from large-scale users.

Best Practices for Application

1. Spray Coverage is Everything
   As a contact herbicide, Glufosinate must touch the green parts of the weed to work. Use fine to medium flat-fan nozzles to ensure complete leaf surface coverage.
2. Apply on Young, Actively Growing Weeds
   The ideal weed height is below 15 cm. Smaller weeds absorb more product and die faster. Large or hardened weeds may only be partially controlled.
3. Time Your Application Properly
   Spray when the weather is dry, sunny, and under 28°C. Avoid windy days to reduce drift and injury to nearby crops.
4. Use Clean Water and Mix Carefully
   Always pre-dilute the herbicide in a small amount of water before adding to the tank. Use clean water, free of mud or fertilizer residues.
5. Stick to the Recommended Dosage
   Overdosing increases risk of crop injury in directed-spray systems; underdosing may result in poor control and promote resistance.
6. Allow Rainfast Time
   Wait at least 4 hours before rain or irrigation. This ensures full leaf absorption.

Common Mistakes to Avoid

Mistake	Result
Spraying on wet weeds (dew, rain)	Product runs off, reducing control by 30–60%
Using it on mature, woody weeds	Only partial leaf damage; root survives
Spraying over non-tolerant crops	Leaf burn, crop stunting, or plant death
Mixing with highly alkaline products	Chemical breakdown or nozzle clogging
Ignoring sprayer calibration	Inconsistent coverage, overdose/underdose zones
Reapplying too soon	No added benefit; may stress the crop or soil

Pro Tip for Orchard and Vineyard Use

When using in orchards or vineyards, always use shielded sprayers or row-directed nozzles. Avoid any direct spray contact with young stems, shoots, or fruits to prevent injury.

Frequently Asked Questions (FAQ)

What is Glufosinate-Ammonium?

Glufosinate-Ammonium is a non-selective, contact herbicide that kills a wide range of annual and perennial weeds. It works by inhibiting glutamine synthetase, leading to a build-up of ammonia in the plant, which disrupts photosynthesis and causes the weed to die. It is widely used in post-emergent weed control, especially in glyphosate-resistant scenarios.

How fast does Glufosinate work?

Visible results appear within 2–3 days, and full weed death usually occurs within 7 to 14 days after application. The weed’s photosynthesis process stops within 2–6 hours, which immediately halts further growth.

How much Glufosinate-Ammonium per litre should I use?

Typical glufosinate ammonium dosage per litre in knapsack sprayers:

• For light infestation: 15–20 ml per litre of water
• For heavy infestation or perennial weeds: 25–30 ml per litre of water

Always follow label guidelines and adjust based on weed size, target crop, and local conditions.

Will Glufosinate kill grass?

Yes. Glufosinate is non-selective and will kill most green vegetation, including broadleaf weeds, sedges, and grasses like foxtail, crabgrass, barnyardgrass, and even bermudagrass or quackgrass if directly contacted.

Can I use Glufosinate in my orchard or vineyard?

Yes. Glufosinate-Ammonium is commonly used as a row-directed spray in orchards and vineyards. Avoid contact with leaves or green stems of trees and vines. It is ideal for controlling weeds between rows or along irrigation lines.

Is Glufosinate safe for the environment?

Yes. Once in the soil, Glufosinate breaks down quickly via microbial activity. It does not leach into groundwater and has low toxicity to birds, bees, and mammals when used properly. However, care should be taken not to spray near open water bodies.

What crops can tolerate Glufosinate?

Only genetically modified crops specifically bred for glufosinate tolerance—such as LibertyLink soybeans, corn, and cotton—can withstand direct application. All other crops should be protected from contact.

Can Glufosinate be mixed with other herbicides?

Yes. It can be safely mixed with glyphosate, atrazine, dicamba, flumioxazin, and many others. Always conduct a jar test before tank-mixing and follow compatibility and crop safety guidelines.

How long is Glufosinate rainfast?

It becomes rainfast within 4 hours after application. Try to spray during periods of stable, dry weather to ensure maximum efficacy.

Is Glufosinate better than glyphosate?

They are different tools:

• Glyphosate is systemic and moves throughout the plant
• Glufosinate is contact-based and kills what it touches

Glufosinate is especially effective on glyphosate-resistant weeds, and often used in rotation or in combination to delay resistance and improve spectrum.
