Talium 20 g/l (Proquinazid, 20 g/l)

Mechanism of Proquinazid Action

The primary value of Talium 20 g/l lies in its active ingredient, Proquinazid. Unlike traditional fungicides that act on general fungal metabolism, Proquinazid serves as a signaling modifier. It specifically disrupts sporulation processes and suppresses the mycelial growth of powdery mildew at the cellular level, preventing the pathogen from invading leaf tissues.

Systemic Protection and Vapor Phase Action

This formulation provides systemic control complemented by a strong vapor phase effect. This property allows the active substance to redistribute itself within the crop canopy, ensuring coverage even where the spray solution has not been applied directly. This is crucial for managing powdery mildew in dense winter and spring cereal stands.

• Disease Suppression: 1–2 applications per season are typically sufficient to block the spread of the pathogen.
• Flexible Dosage: The application rate ranges from 0.15 to 0.25 l/ha, depending on the severity of the infection.
• Safety Profile: Classified as a class 3 hazard, requiring standard safety protocols for field application.

Applying Talium to winter wheat and barley not only arrests active outbreaks of powdery mildew but also establishes a long-lasting protective barrier (up to 20 days pre-harvest). The emulsifiable concentrate formulation ensures excellent adhesion and penetration, minimizing wash-off risks from precipitation.
