Synergistic Action: The Science of 'Tselitel' Fungicide

The high efficacy of 'Tselitel' from Nanjing Essence Fine-Chemical Co. Ltd is rooted in the combination of two distinct active ingredients: metalaxyl and mancozeb. This dual-action approach—combining systemic and contact properties—is essential for controlling aggressive fungal pathogens such as late blight (Phytophthora) and downy mildew (Peronospora).

Core Components and Technical Utility

• Metalaxyl (Phenylamides): Provides systemic protection. Once absorbed, it moves acropetally (upward) through the plant's vascular system, protecting not only the existing foliage but also new growth emerging after the application.
• Mancozeb: Acts as a contact-based 'shield.' It forms a protective barrier on the leaf surface, inhibiting the enzymatic processes of fungal spores and preventing them from germinating and penetrating the host tissue.

Formulated as a wettable powder, 'Tselitel' ensures stable suspension in tank mixes, making it a reliable solution for treating potatoes, tomatoes, cucumbers, onions, and grapevines. The systemic component helps eradicate existing latent infections, while the contact component provides long-lasting preventive protection.

Application Guidelines

For optimal disease management, it is recommended to apply 2.5–3 kg/ha of the product, with a maximum limit of 3 applications per season. As a category 3 hazard product, safety protocols must be followed strictly. A pre-harvest interval (PHI) of 14–20 days is required after the final treatment to ensure safe agricultural practices. This product is an excellent tool for managing resistance and protecting yields in high-pressure disease environments.
