Melodi Duo 66,8WP

Reliable protection for potatoes and grapes

When the harvest is at stake, there is no room for experiments with questionable plant protection products. In my practice, I rely on Melody Duo 66,8WР to fight late blight and downy mildew. I value this combined fungicide for its dual mechanism of action: iprovalicarb provides systemic protection by penetrating plant tissues, while propineb creates a contact barrier on the leaf surface. This synergy effectively stops fungal development at the germination stage.

Application and Dosage

The product is a wettable powder. When preparing the spray solution, it is crucial to ensure a uniform mixture to prevent nozzle clogging. Based on my experience, a rate of 2–2.5 kg/ha is optimal for achieving a dense protective coverage. I carry out no more than three applications per season, which is sufficient to cover the critical development phases of the crops. An important detail: ensure a 30-day pre-harvest interval; this is a safety standard that should not be overlooked.

Key points for the agronomist

• The combination of systemic and contact action minimizes the risk of pathogens developing resistance.
• Hazard class 3 requires standard protective measures when handling the powder.
• Excellent for both preventive use and at the first signs of downy mildew on vineyards.

Working with this product is straightforward if you follow the preparation protocols. The formulation adheres well to the vegetative mass, which is critical in wet weather when the risk of disease outbreaks is at its highest.
