Dithane M 45 is a broad-spectrum fungicide that offers a strong contact mode of action against rust, anthracnose, scab, and other diseases. It works by creating a protective barrier on the plant and stopping fungal spores from germinating and penetrating the plant tissue. The Dithane M 45 fungicide is effective against a wide range of fungal diseases while improving crop health, making it a one-for-all fungal remedy.
Key Features and Benefits of Dithane M 45 Fungicide:
Multi-site Action: Dithane M 45 disrupts the fungus at multiple biological points at once, making it tough for pathogens to form resistance.
Broad-Spectrum: The Dithane M 45 fungicide controls Downy Mildew, Leaf Spot, Blast, Anthracnose, and other fungal diseases.
Supplies Micronutrients: This fungicide also provides essential nutrients like manganese and zinc, improving overall crop growth.
Versatile Application: UPL Dithane M 45 fungicide functions primarily as a preventive application, protecting crops before fungal pathogens infect plant tissues, making it highly versatile.
Safe to Use: Dithane M 45 fungicide is safe for natural predators and beneficial insects, ensuring environmental safety.

How To Use Dithane M 45 Fungicide:
Read the label carefully before measuring the dose of Dithane M 45.
Measure 2 gm of Dithane M 45 fungicide per litre of water — 600–800 gm per acre in 300 litres of water.
Add the required amount of Dithane M 45 directly into a partially filled spray tank with the agitation system running, ensuring it disperses completely into a uniform suspension.
Fill the tank with the remaining water and stir well to form a uniform suspension before spraying.
For best results, spray Dithane M 45 as a preventive application before disease symptoms appear — especially during periods of high humidity, rain, or cool weather that favours fungal infection.
Apply uniformly on all plant surfaces — cover the upper and lower leaf surfaces, stems, and fruit zones completely for maximum protective coverage.
Spray during early morning or late evening — avoid peak midday heat to prevent rapid drying before the product can form its protective layer.
Rinse the sprayer thoroughly with clean water after every use.
Best Time to Apply:
Apply Dithane M 45 fungicide in the early morning or late evening on a calm, dry day. Begin preventive sprays from the early vegetative stage of the crop when conditions favour fungal disease development — for Potato Late Blight, spray from the canopy-closing stage; for Paddy Blast, begin from the tillering stage during humid weather.
Frequency of Application and Re-Entry Period:
Frequency of Application: Apply every 10–14 days during active disease pressure. Dithane M 45 fungicide can be applied multiple times per season without resistance risk due to its multi-site mode of action. Always follow label guidance on maximum applications per season per crop.
Re-Entry Period: Do not enter treated fields for at least 24 hours after spraying without proper protective gear.
Tank-Mix Compatibility: Dithane M 45 is compatible with most systemic fungicides and insecticides — ideal for resistance management when rotated or combined with FRAC Group 3 or 11 fungicides. Always do a jar test before mixing with unfamiliar products.
State Restriction: Dithane M 45 fungicide is restricted in Kerala — do not purchase or use in this state.
Safety Precautions and Handling:
Wear gloves, a mask, and goggles before handling or spraying Dithane M 45 fungicide.
Do not eat, drink, or smoke while mixing or applying the product.
Avoid direct skin and eye contact — wash immediately with plenty of clean water if contact occurs.
