Mechanism of Action: Molecular Defense Strategy

At the core of "Syllit, SC" is dodine, a fungicide belonging to the guanidine class. Its efficacy against apple scab (Venturia inaequalis) stems from its unique ability to disrupt the permeability of pathogen cell membranes. Unlike many systemic agents, dodine acts as a potent contact fungicide with significant therapeutic properties during the early stages of infection.

The Significance of Suspension Concentrate

The SC formulation ensures optimal dispersion of the active ingredient particles. Upon application to the leaf surface, the dodine particles distribute evenly, creating a robust protective film. This is critical for preventing conidial germination: the fungicide "envelops" the potential infection site, denying the fungus the opportunity to establish itself within the plant tissues.

Practical Application Details

• Contact Protection: The product works directly on the surface, making it indispensable for resistance management programs.
• Dosage: A usage rate of 1.5–2.5 L/ha allows for flexible adjustments based on infection pressure and canopy density.
• Regulation: The limit of 2 applications per season and a 30-day pre-harvest interval require precise planning, focusing on critical scab development phases.

Manufactured by Arysta LifeScience S.A.S. (France), the product demonstrates stable performance even under cool spring conditions, when pathogens are most active and systemic fungicides may suffer from reduced efficacy due to slower plant metabolism.
