What Is Captan?

Captan is a fungicide active ingredient used for plant disease management.

Its main value is protective contact activity. It works mainly on treated plant surfaces and helps protect crops against listed fungal diseases where locally approved.

Captan should be positioned as a preventive fungicide. It is not a systemic fungicide and should not be described as a product that moves inside the plant for internal disease control.

For fruit, vegetable, ornamental, and approved crop disease programs, Captan can be used as part of a planned protection schedule according to local registration and label instructions.

How Captan Works

Captan works as a contact fungicide.

After application, it remains mainly on treated plant surfaces and helps protect the crop surface against fungal disease development. Because of this working pattern, Captan is usually positioned before infection pressure becomes severe.

This is important for product positioning.

Captan should be described as:

• a protectant fungicide
• a contact fungicide
• a multi-site active ingredient
• a preventive disease management tool

Captan should not be described as:

• a systemic fungicide
• a curative fungicide for severe infection
• an internal plant protection product
• a guaranteed disease control solution
• a product for all crops or all fungal diseases

Final use direction must follow the approved local label.

Captan Mode of Action

Captan belongs to FRAC M04.

It is classified as a multi-site contact fungicide. This means its activity is not based on one single biochemical target site in the pathogen.

For product positioning, this gives Captan strong value in preventive disease management programs and resistance management planning. However, it should not be described as resistance-proof.

Captan use should still follow local resistance management guidance, approved crop programs, label instructions, and integrated disease management principles.

Main Crop and Disease Positioning

Captan is commonly positioned for disease programs in fruit crops, vegetables, ornamentals, and other approved crop markets.

Crop / Market Direction	Disease Program Positioning
Apples and pears	Scab and fruit disease protection where locally approved
Grapes	Bunch rot, Botrytis, and downy mildew-related programs where approved
Strawberries	Botrytis / gray mold direction where locally approved
Stone fruits	Brown rot and leaf disease program positioning
Vegetables	Leaf spot, anthracnose, and downy mildew-related programs where approved
Ornamentals	Leaf spot and ornamental disease programs
Approved crop programs	Final crop and disease scope must follow local label instructions

Disease claims must be controlled carefully. Captan should not be presented as a universal fungicide for all crop diseases.

Final crop scope, disease spectrum, timing, dose, interval, and application method must follow local registration and approved label instructions.

Available Formulations: Captan 80% WDG and 50% WP

POMAIS supplies Captan in two main formulation options:

• Captan 80% WDG
• Captan 50% WP

Both products use Captan as the active ingredient. The main difference is formulation type, active ingredient concentration, market positioning, and packaging preference.

The right option depends on your target market, registration format, product line strategy, packaging plan, and local distribution channel.

Captan 80% WDG Formulation Features

Captan 80% WDG is a higher-loading water-dispersible granule formulation.

WDG means water-dispersible granule. This dry granule format is suitable for markets that prefer higher active ingredient content and granule-style dry formulation products.

Key formulation value:

• Higher active ingredient content
• Water-dispersible granule format
• Dry granule product positioning
• Lower-dust positioning compared with traditional powder formats
• Suitable for bags, sachets, cartons, and export packing
• Suitable for premium dry fungicide product lines
• Clear specification for registration and procurement comparison

Captan 80% WDG should not be described as automatically stronger or more effective than Captan 50% WP. Field performance depends on approved label use, formulation quality, disease pressure, crop condition, timing, and application program.

Captan 50% WP Formulation Features

Captan 50% WP is a traditional wettable powder formulation.

WP means wettable powder. This formulation is suitable for mature powder product channels and flexible private label packaging plans.

Key formulation value:

• Wettable powder formulation
• Mature dry formulation type
• Suitable for sachets, bags, cartons, and export cartons
• Practical for established powder fungicide markets
• Flexible for private label product lines
• Suitable for price-positioned or traditional distribution channels
• Clear specification for registration and procurement documents

Captan 50% WP should not be described as a lower-quality product. It is a different formulation option for markets that prefer wettable powder products.

Choosing the Right Captan Formulation for Your Market

Captan 80% WDG and Captan 50% WP should be selected according to market need, not by a simple “better or worse” judgment.

Market Need	Suitable Option
Higher active content dry formulation	Captan 80% WDG
Water-dispersible granule format	Captan 80% WDG
Traditional wettable powder channel	Captan 50% WP
Flexible sachet and bag supply	Captan 50% WP
Premium dry formulation positioning	Captan 80% WDG
Mature powder product line	Captan 50% WP
Private label fungicide supply	Both formulations
Export carton and bag packaging	Both formulations

For registration-oriented markets, the selected formulation should match the target label format, local crop direction, packaging size, and import requirements.

Application Guidance

Use Captan only where locally approved.

General use principles:

• Follow the approved local label.
• Use only on registered crops and approved diseases.
• Position Captan mainly as a protectant fungicide.
• Apply according to the approved timing and crop program.
• Do not claim systemic or curative activity.
• Do not use on crops or diseases not listed on the local label.
• Tank mix, oil compatibility, and application sequence must follow local label instructions.
• Use as part of an integrated disease management program.

No specific dose, dilution rate, spray interval, application frequency, crop stage operation, or tank mix advice should be used without an approved local label.

Crop Safety and Use Boundary

Crop safety depends on crop species, variety, growth stage, weather, disease pressure, tank mix, application timing, formulation type, and approved label use.

Captan should be positioned clearly.

It is:

• a protectant contact fungicide
• a multi-site active ingredient
• a preventive disease management product
• available in WDG and WP dry formulations

It is not:

• a systemic fungicide
• a curative disease treatment for severe infection
• a universal fungicide for all crops
• a product that can be used without label guidance
• a guarantee of complete disease control

Final crop scope and use boundary must follow local registration and approved label instructions.

Resistance Management

Captan belongs to FRAC M04 multi-site contact fungicides.

Multi-site fungicides are valuable in disease resistance management programs. They can support rotation and protection strategies when used correctly.

Recommended program principles:

• Avoid relying on one fungicide type throughout the season.
• Use registered rotation or combination programs where locally allowed.
• Follow local resistance management guidance.
• Combine fungicide use with crop hygiene and field management.
• Monitor disease development and control performance.
• Follow the approved local label.

Captan should not be described as resistance-proof or as a product that solves fungicide resistance alone.

Storage and Transport

Store Captan formulations in sealed original packaging.

General storage principles:

• Keep in a cool, dry, and ventilated place.
• Avoid moisture, direct sunlight, and high temperature.
• Keep away from food, feed, seed, and incompatible materials.
• Keep packages tightly closed before use.
• Protect bags, sachets, cartons, and outer packing from damage.
• Follow SDS and local transport requirements.

For Captan 80% WDG, quality attention should include granule appearance, dispersibility, moisture control, package sealing, and carton protection.

For Captan 50% WP, quality attention should include powder appearance, wetting performance, moisture control, dust awareness, package sealing, and carton protection.
