Talius 20

Advanced Mechanism for Powdery Mildew Control

The efficacy of Talius 20 is derived from its active ingredient, proquinazid, which belongs to the unique chemical class of quinazolinones. Unlike conventional triazoles or strobilurins, this molecule does not merely inhibit mycelial growth; it triggers the plant's natural defense mechanisms. At a molecular level, it suppresses the formation of pathogen appressoria and blocks spore germination, establishing the product as a critical component in anti-resistance management programs for cereals.

Technical Performance: Systemic and Vapor Action

Talius 20 exhibits a distinct translaminar effect and, crucially, a vapor phase activity. This is vital for dense wheat and barley stands where canopy penetration is often compromised. Proquinazid creates a protective 'cloud' around the treated leaf, which redistributes to untreated areas, significantly mitigating risks associated with sub-optimal spray coverage.

• Dual Action: Combines systemic and contact properties, providing both immediate curative effects and prolonged protection for 4–6 weeks.
• Vapor Activity: Enables control of pathogens in lower, hard-to-reach leaf tiers.
• Resistance Management: Zero cross-resistance risk due to the specific mode of action on the fungal metabolism.

Field Application Guidelines

To achieve maximum biological performance, apply Talius 20 at a rate of 0.15–0.25 L/ha. The product is most effective when used preventively or upon the first visual signs of infection. Given its strong prophylactic profile, Talius 20 reduces the disease pressure on the crop during the critical stages of tillering and stem elongation. The formulation allows for a maximum of two applications per season, with a pre-harvest interval of 30 days, ensuring full compliance with safety standards for grain production.
