Main Functions

Imazalil 50% EC is mainly used to:

• Control post-harvest fungal decay
• Reduce storage rot pressure
• Protect fruit quality during handling and transport
• Support fruit preservation programs
• Maintain more stable shelf performance in registered fruit lines

Its main role is post-harvest disease management.

Mode of Action

Imazalil belongs to the DMI fungicides in FRAC Group 3. FRAC places imazalil under G1: DMI fungicides (SBI Class I), targeting C14-demethylase in sterol biosynthesis. JMPR describes imazalil as an imidazole fungicide with protective, curative, and anti-sporulation activity.

This gives Imazalil 50% EC a clear technical role in post-harvest fruit programs where decay organisms must be controlled on harvested fruit rather than in a broad field-disease program. Because the product is described as systemic, it is associated with more than simple surface-only protection.

Target Diseases

Imazalil 50% EC is mainly used for:

• Green mold
• Blue mold
• Stem-end rot
• Post-harvest storage decay

In citrus pathology references, green mold and blue mold are identified as major citrus post-harvest diseases caused by Penicillium digitatum and Penicillium italicum, and imazalil is widely used to control them.

Suitable Crops and Application Areas

Imazalil 50% EC is suitable for registered post-harvest fruit programs. Citrus crops are the recommended use, and application to other approved fruit crops is permitted, subject to local registration status. EPA also identifies bananas and citrus as post-harvest uses for imazalil.

This means the formulation fits fruit programs where the main concern is not field infection before harvest, but decay development during packing, storage, shipment, and market circulation. Final crop scope should always follow the approved local label in the destination market.

Application Guidance

Imazalil 50% EC should be used according to the approved local label. Its main use pattern is post-harvest fruit treatment, not general foliar field spraying. Imazalil is a post-harvest fungicide; it can be used in packing plants, during the storage phase, and for fruit preservation purposes.

In general, this formulation is suitable when:

• the fruit program needs post-harvest decay control
• the main disease risk is green mold, blue mold, stem-end rot, or related storage decay
• the product is being used in a registered fruit treatment program
• the objective is to protect fruit quality during storage and transport

Final dosage, treatment method, timing, and residue-management requirements should follow the local approved label.

Formulation Features

EC means emulsifiable concentrate. CIPAC lists EC as the standard code for emulsifiable concentrate. This is a liquid formulation type designed to form an emulsion after dilution in water.

The 50% EC specification gives Imazalil 50% EC a liquid post-harvest fungicide format suitable for standard fruit-treatment preparation where EC formulations are accepted under the local label.

Product Advantages

Imazalil 50% EC stands out for these reasons:

• Clear post-harvest fruit protection function
• Systemic fungicide activity
• Protective, curative, and anti-sporulation profile
• FRAC Group 3 DMI fungicide classification
• Strong fit for green mold, blue mold, and storage decay programs
• Liquid EC formulation

Its main technical strength is the combination of post-harvest fruit focus and a well-established imidazole fungicide mode of action for storage-decay management.

Safety and Use Precautions

Imazalil 50% EC should be handled carefully during mixing, treatment, storage, and transport. It should be used according to the approved local label and local residue, crop-use, and post-harvest compliance requirements. The label for imazalil must include specific post-harvest treatment instructions for the intended use of the treated fruit.

Important points include:

• follow the approved local label
• keep away from food, feed, and drinking water except for approved fruit-treatment use systems
• use proper protective clothing, gloves, and face protection
• manage the product within a registered post-harvest treatment program
• pay attention to crop scope, residue requirements, and destination-market rules

These points are especially important because post-harvest fruit products are closely tied to market access and residue compliance.

Storage and Transport

Store Imazalil 50% EC in the original sealed package in a cool, dry, and well-ventilated place. Keep it away from direct sunlight, heat sources, food, feed, and unauthorized access. As an EC liquid formulation, the product should be protected from leakage, package damage, and improper storage conditions that could affect formulation stability.

During transport, containers should be protected from rough handling, inversion, high heat, and moisture exposure so that package integrity and formulation quality remain stable before use.
