Chlorothalonil 37.5% + Dimethomorph 5% + Cymoxanil 5% SC is a broad-spectrum fungicide designed to offer superior protection against a range of fungal diseases in agriculture. This formulation combines three powerful active ingredients, each targeting different mechanisms of fungal growth, to provide preventive and curative action.

• Chlorothalonil is a multi-site contact fungicide that inhibits the germination and growth of fungal spores, ensuring long-lasting control over pathogens.
• Dimethomorph is a systemic fungicide that interferes with the fungal cell wall synthesis, providing internal protection to the plant tissues.
• Cymoxanil offers protective and curative control by inhibiting fungal development and sporulation, making it particularly effective against downy mildew and late blight.

Together, these active ingredients deliver comprehensive protection for crops, reducing the risk of disease outbreaks and promoting healthier growth.

How Does Chlorothalonil + Dimethomorph + Cymoxanil Work?

• Chlorothalonil: A multi-site contact fungicide that inhibits several enzyme systems necessary for fungal cell metabolism. It creates a chemical barrier on the plant surface, preventing spore germination and infection establishment.

• Dimethomorph: A locally systemic fungicide that penetrates plant tissues and disrupts fungal cell wall biosynthesis, offering internal protection. Especially effective against oomycetes like Phytophthora and Peronospora.

• Cymoxanil: A rapid-acting penetrant that inhibits protein synthesis and DNA replication in fungal pathogens. It offers strong curative and anti-sporulation effects against early-stage infections.

Triple Mode Advantage: This combination ensures simultaneous surface protection, internal systemic defense, and curative control, significantly lowering the risk of secondary infection and fungal adaptation.

Key Benefits:

• Triple Action Formula: Combines contact and systemic action for comprehensive disease control.
• Long-lasting Protection: Provides extended residual activity, preventing reinfection over time.
• Effective Against Multiple Diseases: Controls a variety of fungal pathogens, including late blight, downy mildew, and powdery mildew.
• Enhanced Crop Health: By preventing diseases, this fungicide helps promote stronger, healthier plants and improves yield quality.
• User-Friendly: The Suspension Concentrate (SC) formulation ensures easy mixing and application.

Onions	Downy Mildew, Fusarium	20-30 ml per 10 L of water per 100m²	14

• Application Rate: 2-3 liters per hectare.
• Spray Volume: 200-400 L per hectare depending on crop size.
• Application Interval: Apply at intervals of 7-14 days depending on disease pressure.

Extended Crop and Disease Spectrum

In addition to protecting tomatoes, potatoes, grapes, and cucumbers, this fungicide is highly effective for:

• Peppers – Phytophthora root rot, blight

• Melons (Cantaloupe, Watermelon) – Downy mildew

• Lettuce – Downy mildew, leaf spots

• Eggplant – Early blight

• Beans – Anthracnose, downy mildew

• Onions and Garlic – Fusarium basal rot, downy mildew

• Ornamentals (Roses, Geraniums) – Alternaria leaf spot, Botrytis

This broad-spectrum control makes it ideal for growers managing diverse cropping systems or mixed farms.

Usage Instructions:

1. Preventive Application: Apply the fungicide when disease symptoms first appear or as part of a regular preventive spraying program.
2. Spray Thoroughly: Ensure complete coverage of plant surfaces, especially the undersides of leaves where fungal spores often develop.
3. Intervals: Reapply every 7-14 days depending on weather conditions, crop type, and disease pressure.

Packaging Information:

• Packaging Type: Available in 1L, 5L, 10L plastic containers or bulk packaging for larger volumes.
• Design: The packaging features eye-catching graphics, clearly displaying the product name and active ingredients, with safety warnings and usage instructions.

Advantages:

• Broad-Spectrum Activity: The combination of Chlorothalonil, Dimethomorph, and Cymoxanil provides protection against multiple fungal diseases in various crops.
• Enhanced Efficacy: By combining contact and systemic modes of action, this product ensures thorough protection that reaches both the plant surface and internal tissues.
• Safe for Pollinators: Non-toxic to bees and beneficial insects, making it safer for the environment.
• Cost-effective: The low application rate ensures that this fungicide provides excellent value for money, especially for large-scale agricultural operations.

Resistance Management Best Practices

• Rotate with fungicides from different chemical groups such as QoIs (Strobilurins) or SDHIs to minimize resistance risk.

• Limit consecutive applications to two treatments before switching modes of action.

• Incorporate into an Integrated Disease Management (IDM) program alongside cultural and biological controls.

Tank Mixing Recommendations:

• Compatible with most contact insecticides (e.g., lambda-cyhalothrin, deltamethrin) and foliar nutrients.

• Always conduct a small-scale jar test before large batch mixing.

• Avoid mixing with highly alkaline products (e.g., Bordeaux mixture, strong bases).
