Glufosinate-Ammonium Herbicide

Glufosinate-Ammonium Herbicide is a fast-acting, non-selective post-emergence herbicide designed to control a broad spectrum of annual and perennial weeds—including glyphosate-resistant species. Engineered for commercial agriculture, plantation management, and vegetation control in non-cultivated areas, this contact herbicide delivers rapid weed burndown with lasting residual activity.

Key Highlights:

Kills tough weeds (including glyphosate-resistant pigweed, marestail, etc.)
Visible results in 1–2 days
Residual control for up to 45 days
Low resistance risk (Group 10 mode of action)
Rainfast within 4 hours

Active Ingredient: Glufosinate-ammonium (CAS No. 77182-82-2)
Molecular Formula: C₅H₁₅N₂O₄P
Mode of Action: Inhibits glutamine synthetase, causing toxic ammonia buildup in plant cells → disrupted photosynthesis → rapid cell death.
Formulations:
- 200g/L Soluble Concentrate (SL): Liquid for foliar spraying (standard for post-emergence use).
- 50% Soluble Granule (SG): Dust-free granules for soil or foliar application.
- Custom Blends:
  - Glufosinate + Glyphosate (broad-spectrum systemic + contact control).
  - Glufosinate + Dicamba/MCPA (enhanced broadleaf weed suppression).
  - Glufosinate + Flumioxazin (residual soil activity).

Key Benefits

Rapid Weed Control:
- Visible symptoms (chlorosis, necrosis) within 2–3 days.
- Full weed death in 7–14 days for annuals; 14–21 days for perennials.
- Rainfast within 4 hours of application, ensuring reliability in variable weather.
Broad-Spectrum Efficacy:
- Annual Weeds: Pigweed, crabgrass, foxtail, lambsquarters, marestail (including glyphosate-resistant biotypes).
- Perennial Weeds: Bermudagrass, quackgrass, Canada thistle, yellow nutsedge.
- Resistant Species: Effective on glyphosate-resistant Amaranthus, Conyza, and Lolium spp.
Crop & Environmental Safety:
- Tolerant Crops: Safe for use in glufosinate-tolerant GM crops (e.g., LibertyLink® soybeans, corn, cotton).
- Non-Crop Use: Ideal for directed sprays in orchards, vineyards, and non-cultivated areas (e.g., roadsides, plantations).
- Low Environmental Impact: Biodegradable in soil (half-life: 1–4 weeks), low leaching risk, and minimal toxicity to bees/birds when used as directed.
Flexible Application:
- Crop Systems: Post-emergence foliar spray for row crops, tree crops, and vegetables.
- Application Methods: Broadcast, directed, or shielded sprays (avoid contact with non-tolerant crop foliage).
- Dosage Range:
  - Annual weeds: 500–750 ml/ha (SL formulation).
  - Perennial weeds/heavy infestations: 1–1.5 L/ha.
  - Backpack sprayers: 15–30 ml/L water (adjust for weed size and density).

Target Applications

Crop/Area	Use Case	Key Benefits
GM Crops	Post-emergence weed control in glufosinate-tolerant soybeans, corn, cotton.	Safe for direct application; resistance management.
Orchards & Vineyards	Directed sprays between rows to control perennials (e.g., bermudagrass).	Reduces crop contact risk; maintains clean rows.
Potato Fields	Pre-harvest vine dry-down or post-harvest stubble kill.	Eases mechanical harvesting; controls annual weeds.
Non-Crop Areas	Roadside, industrial, and plantation weed control.	Long residual (25–45 days); low soil mobility.

Resistance Management

Mode of Action Group: HRAC Group 10 (unique site of action vs. glyphosate’s Group 9).
Strategies:
- Rotation: Alternate with Group 2 (ALS inhibitors), Group 4 (hormone herbicides), or Group 14 (PPO inhibitors).
- Tank Mixes: Combine with residual herbicides to target multiple growth stages.
- Sequential Application: Use after pre-emergent herbicides to control escapes.

Packaging & Custom Solutions

Standard Packaging:
- SL: 100ml, 500ml, 1L, 5L bottles; 20L/200L drums.
- SG: 250g, 1kg, 5kg bags; 25kg cartons.
Custom Services:
- Private labeling with multi-language artwork.

Safety & Compliance

Toxicity: Low mammalian toxicity (LD₅₀ > 2000 mg/kg); always wear PPE (gloves, goggles) during handling.
Regulatory Compliance: Meets ISO 9001, FAO, and regional standards (e.g., EPA, APVMA).
Storage: Store in cool, dry conditions; avoid direct sunlight and moisture.

Glufosinate-Ammonium Herbicide FAQ

1. What is Glufosinate-Ammonium?

Glufosinate-ammonium is a non-selective, contact herbicide that kills broadleaf weeds, grasses, and sedges by inhibiting the enzyme glutamine synthetase. This leads to toxic ammonia buildup in plant cells, disrupting photosynthesis and causing rapid cell death.

2. How does Glufosinate-Ammonium work?

Mode of Action: Blocks glutamine synthetase, halting ammonia detoxification and glutamine synthesis.
Speed: Photosynthesis stops within 2–6 hours; visible yellowing (chlorosis) appears in 2–3 days, with full weed death in 7–14 days.
Contact vs. Systemic: Acts locally on contacted tissues (non-systemic), making it ideal for spot or directed spraying.

3. What weeds does it control?

Annuals: Pigweed, crabgrass, foxtail, lambsquarters, marestail (including glyphosate-resistant strains).
Perennials: Bermudagrass, quackgrass, Canada thistle, nutsedges.
Resistant Biotypes: Effective on weeds immune to glyphosate (e.g., Palmer amaranth, marestail).

4. Where can it be applied?

Crops: Genetically modified glufosinate-tolerant soybeans, corn, and cotton.
Non-Crop Areas: Orchards, vineyards (between rows), potato fields, roadsides, and plantations.
Specialty Use: Pre-harvest vine dry-down in potatoes and directed sprays in orchards.

5. What are the common formulations?

200g/L Soluble Concentrate (SL): Liquid for foliar spraying (most common).
50% Soluble Granule (SG): Dust-free, long-shelf-life option for soil or foliar use.
Custom Blends: Mixed with glyphosate, dicamba, or flumioxazin for broader spectrum or residual control.

6. What is the dosage?

General Rate: 500–750 ml/ha (SL formulation) for annual weeds; 1–1.5 L/ha for perennials or heavy infestations.
Backpack Sprayers: 15–30 ml/L water (adjust for weed size: higher rates for tough weeds).

7. Is it rainfast?

Yes, it becomes rainfast within 4 hours of application. If rain occurs sooner, reapplication may be needed for full efficacy.

8. Can it be mixed with other herbicides?

Yes. Common tank mixes include:
- Glyphosate: Combines contact (glufosinate) and systemic (glyphosate) action.
- Dicamba/MCPA: Enhances broadleaf weed control.
- Flumioxazin: Adds residual soil activity to prevent re-growth.
Caution: Always test compatibility with a jar test and follow label guidelines.

9. Is Glufosinate-Ammonium safe for crops?

Tolerant Crops: Safe for genetically modified varieties (e.g., LibertyLink® crops).
Non-Tolerant Crops: Causes leaf burn if sprayed directly; use shield…
