🧪 Product Overview:

Metiram is a non-systemic, contact fungicide with a broad spectrum of activity against a variety of fungal diseases affecting fruits, vegetables, and field crops. As a protective fungicide, it forms a barrier on plant surfaces that inhibits fungal spore germination and prevents infection.

What sets Metiram apart is its multi-site mode of action, which targets multiple biochemical pathways in fungi, making it highly effective and resistant to the development of resistance. Additionally, Metiram contains essential micronutrients like zinc and manganese, which contribute to overall plant health and vigor.

🌾 Key Benefits:

• ✅ Broad-spectrum efficacy against numerous fungal pathogens

• ✅ Multi-site action reduces resistance risk

• ✅ Provides added micronutrients (Zn and Mn) for improved plant growth

• ✅ Suitable for preventive spraying programs

• ✅ Compatible with systemic fungicides for integrated protection

• ✅ Effective in both humid and dry conditions when applied correctly

🌱 Crops Protected:

• Fruits: Grapes, apples, citrus, bananas, pears

• Vegetables: Potatoes, tomatoes, onions, cucurbits, carrots

• Field Crops: Sugar beet, peanuts, tobacco

• Ornamentals: Roses, chrysanthemums

🦠 Target Fungal Diseases:

• Downy Mildew (Plasmopara viticola, Peronospora spp.)

• Early and Late Blight (Alternaria solani, Phytophthora infestans)

• Scab (Venturia inaequalis)

• Rusts (Puccinia spp.)

• Anthracnose (Colletotrichum spp.)

• Leaf Spots (Cercospora, Alternaria, Septoria)

• Black Spot, Powdery Mildew (partial suppression when tank-mixed)

⚙️ Mode of Action:

Metiram works by interfering with essential enzyme systems in fungal spores, particularly those involving sulfhydryl groups, which are critical to respiration and metabolism. It prevents spore germination and fungal development on treated plant surfaces.

• Non-systemic: Does not penetrate plant tissue

• Protectant: Must be applied before infection occurs

• Contact Action: Requires thorough coverage for maximum effectiveness

📋 Application & Usage:

• Ensure uniform coverage of plant surfaces

• Do not apply during rain or high winds

• Can be tank-mixed with systemic fungicides for curative action

⚠️ Handling & Safety Information:

• Toxicity: Low to moderate for mammals; use PPE

• Environmental Impact:

  • Harmful to aquatic life – avoid runoff into water bodies

  • Not phytotoxic when used as directed

• Storage:

  • Keep in original, sealed packaging

  • Store in a dry, cool, well-ventilated area

• Re-entry Interval (REI): 12–24 hours

• Pre-Harvest Interval (PHI): 7–21 days (depending on crop)

🔄 Compatibility & Resistance Management:

• Metiram is highly compatible with many systemic fungicides like triazoles, strobilurins, and phenylamides

• Use in rotation or in combination with single-site fungicides to reduce resistance risk

• Ideal for use in IPM (Integrated Pest Management) programs

✅ Conclusion:

Metiram offers dependable, cost-effective disease control across a wide range of crops. Its broad-spectrum, protective action and low resistance risk make it a valuable choice for farmers and growers looking to secure high yields and healthy plants. With the added benefit of zinc and manganese, Metiram not only protects your crops—it helps them thrive.
