Tattu

Synergy of Action: Technical Analysis of Tattu

Tattu by Bayer is a specialized fungicide designed to protect solanaceous crops by combining systemic and contact efficacy. The formulation relies on a precise balance of propamocarb hydrochloride (375 g/l) and mancozeb (250 g/l). This dual-action approach is critical for managing yield-threatening pathogens in potatoes and tomatoes.

Inside the Formulation: How It Protects

• Propamocarb Hydrochloride (Carbamates): A systemic agent that is absorbed into the plant's vascular tissues. It acts by disrupting the development of fungal mycelium, while also promoting plant physiological activity, which strengthens the crop’s natural defenses. Because it is systemic, it continues to protect new foliage even after application.
• Mancozeb: Acts as a contact shield. It forms a protective layer on the leaf surface, effectively blocking spore germination and preventing primary infections.

This technical composition creates a robust defense against Alternaria and ensures long-term resistance against Phytophthora (Late Blight). By utilizing a systemic path, Tattu provides coverage that remains active even as the plant continues to grow.

Field Application and Handling

Tattu comes as a suspension concentrate, ensuring excellent tank stability and dispersion. To maximize efficacy and adhere to safety standards, note the following parameters:

• Application Rate: 2.0 to 3.0 liters per hectare, adjusted for pathogen pressure.
• Frequency: A maximum of 3 applications per season.
• Pre-harvest Interval (PHI): The final application must be made at least 20 days prior to harvest.

Classified under Hazard Class 3, standard safety protocols are required for application. Integrating Tattu into a crop protection strategy provides growers with a reliable, proven tool to mitigate losses caused by fungal outbreaks, particularly in high-humidity climates where disease development is most rapid.
