How Imazalil Works: Targeted Defense Against Green and Blue Mold

Imazalil is a systemic fungicide from the imidazole family that offers highly effective post-harvest disease control, especially against Penicillium digitatum (green mold) and Penicillium italicum (blue mold), two of the most damaging fungi found on stored citrus and soft fruits.

Mechanism of Action: Blocking Fungal Growth at the Cellular Level

Imazalil works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes.

Here’s how it works:

1. Fungal cells need ergosterol to maintain strong, functional membranes.
2. Imazalil interferes with ergosterol production, weakening the cell membrane structure.
3. As a result, fungal cells become leaky and unable to survive, leading to rapid die-off.
4. In fruit, this prevents the mold from establishing or spreading, even during long-distance cold-chain storage.

---

Is Imazalil Systemic?

Yes. Imazalil is a systemic fungicide:

• It penetrates the fruit peel during dipping or spraying.
• Moves into the upper cell layers, offering protection beyond the surface.
• Provides residual protection even after washing or waxing.

This systemic activity makes it more reliable than contact-only fungicides for long-term storage and export fruit handling.

---

Why It’s Ideal for Post-Harvest Use

• Targets the exact fungi that thrive after harvest, especially in warm, humid environments.
• Offers both preventive and curative action—controls active infections and protects against new ones.
• Absorbs quickly and does not damage fruit quality or appearance.

---

In summary, Imazalil stops mold at the source—inside the fruit skin—where surface treatments often fail. That’s why it’s trusted by citrus exporters and packing houses worldwide.

Target Fruits and Pathogens: Where Imazalil Delivers Its Full Potential

Imazalil fungicide is specially designed for post-harvest application in fruits that are vulnerable to storage mold and decay. It is particularly effective on citrus and tropical fruits, where Penicillium species can cause major economic loss during packaging, shipping, and retail.

Below is an overview of key crops and fungal targets:

---

1. Citrus Fruits (Oranges, Mandarins, Lemons)

Target Pathogens	Application Method	Notes
Penicillium digitatum (green mold)	Dip, spray, or wax mix	Main cause of citrus decay post-harvest
Penicillium italicum (blue mold)	Dip or wax coating	Affects stored citrus during long-haul export
Stem-end rot (various fungi)	Dip with 0.02%–0.05% EC	Apply within 24 hours of harvest

These are the most common molds found on oranges and mandarins, making imazalil on oranges a standard practice in many citrus packing houses.

---

2. Bananas

Target Pathogens	Application Method	Notes
Crown rot (Fusarium, Colletotrichum)	Crown dip or post-wash spray	Especially during packing and export
Anthracnose, cigar-end rot	Light surface spray	Can be combined with other post-harvest treatments

Bananas are often treated with imazalil at low doses after harvest to avoid stem discoloration and early ripening rot.

---

3. Grapes

Target Pathogen	Application	Notes
Botrytis cinerea (gray mold)	Quick spray or dip	Especially during cool storage and long-distance transport

Imazalil is not curative for deep infections in grapes, but works well to suppress surface contamination and extend freshness.

---

4. Apples (in fruit wax processing)

Though not as common as in citrus, imazalil may be added to apple wax coatings for added protection against:

• Storage mold
• Stem-end decay

Use concentration should follow wax formulation guidance to avoid visual residue.

---

Summary of Target Use Cases

Crop	Use Type	Treatment Goal
Oranges, citrus	Dip, spray, wax	Prevent green/blue mold during storage
Bananas	Crown dip/spray	Delay stem rot and transport-related decay
Grapes	Light dip/spray	Control gray mold in cold chain
Apples	Wax integration	Supplemental protection during distribution

Wherever fruit is stored, shipped, or waxed—Imazalil fungicide protects the value you harvest.

Recommended Application Methods and Dosage: How to Use Imazalil Effectively

Imazalil 500g/L EC is formulated for low-dose, high-efficiency post-harvest protection. Its emulsifiable nature makes it easy to mix with water or wax solutions, ensuring even distribution over the fruit surface or penetration into vulnerable crown and stem-end areas.

Here’s how to apply it effectively across different settings:

---

1. Fruit Dipping

Ideal for: Oranges, mandarins, bananas, grapes

Concentration	0.02% – 0.05% solution (200–500 ppm)
Mixing Rate	40–100 ml of Imazalil EC per 100 L of clean water
Dipping Time	30 seconds – 2 minutes, depending on fruit type
Tips	Ensure fruit is clean and dry before dipping. Agitate the tank regularly for even concentration. Avoid overly long soaking.

This method is the most effective way to deliver systemic protection directly into the peel of the fruit.

---

2. Post-Harvest Spray

Ideal for: Packing lines or semi-mechanized operations

Concentration	0.05% solution (500 ppm)
Equipment	High-volume mist sprayer or tunnel sprayer
Timing	After cleaning and grading, before packaging
Tips	Spray should cover crown, calyx, and stem-end. Use soft nozzles to avoid bruising. Allow drying before box packing.

This method offers quick, large-scale coverage with minimal residue buildup.

---

3. Wax Emulsion Integration

Ideal for: Oranges, apples, mandarins (export-grade)

Concentration	Add 0.02% – 0.05% of Imazalil EC to fruit wax
Example	20–50 ml per 100 L of wax formulation
Benefits	Dual function: gloss + mold protection during long-haul transport
Notes	Maintain constant stirring in wax tank to ensure suspension. Do not exceed max concentration to avoid wax film issues.

This technique is particularly useful in supermarket-preferred fruit lines, where shelf appeal and mold resistance are both critical.

---

4. Crown Dip for Bananas

Ideal for: Export or storage bananas

Concentration	0.05% (500 ppm) solution
Application	Dip only the crown (cut stem area) for 10–30 seconds
Goal	Prevent crown rot, reduce stem-end darkening
Notes	Combine with disinfectant (e.g., aluminum sulfate) if needed. Dry well before packing.

---

General Application Best Practices

• Water quality matters: Use clean, neutral pH water for mixing
• Apply soon after harvest: The earlier the better to prevent pathogen establishment
• Avoid sunlight exposure during application to prevent degradation
• Storage interval: Treated fruit can enter cold storage or transport immediately after drying

---

With correct dosage and method, Imazalil helps preserve fruit quality, reduce post-harvest losses, and meet export phytosanitary requirements.

Frequently Asked Questions (FAQ) & Buyer’s Guide

What is Imazalil used for?

Imazalil fungicide is mainly used for post-harvest treatment of fruits, especially citrus fruits like oranges and mandarins, to control fungal infections such as green mold and blue mold. It can also be used on bananas, grapes, and in fruit wax mixtures.

---

How does Imazalil work?

It inhibits ergosterol synthesis, a key component of fungal cell membranes. Without ergosterol, fungal cells cannot maintain structure, leading to cell damage and death. This makes Imazalil highly effective both as a preventive and curative treatment.

---

Is Imazalil systemic?

Yes. Imazalil penetrates the fruit peel, offering internal protection beyond just the surface. This systemic activity helps maintain fruit quality during long shipping and storage.

---

Can I use Imazalil on oranges?

Absolutely. Imazalil on oranges is one of the most common post-harvest treatments in the citrus industry. It protects the fruit from Penicillium decay, especially during export or prolonged storage.

---

What concentration should I use?

• Dipping or spraying: 0.02%–0.05% (200–500 ppm)
• Fruit wax integration: 0.02%–0.05% into wax coating
• Always follow label instructions and regional MRL standards.

---

What is the shelf life of Imazalil?

24 months from production date when stored in sealed original packaging under recommended conditions.

---

Is Imazalil approved for export fruit?

Yes. Imazalil is used globally and conforms to maximum residue limits (MRLs) in most major markets including the EU, Middle East, Africa, and Latin America, when applied correctly.

---

Can I buy Imazalil in bulk or request OEM production?

Yes. We offer:

• Bulk supply of 500g/L EC formulation
