Talios 20

Technical breakdown of Talius 20: The Power of Proquinazid

The Talius 20 fungicide, developed by DuPont Ukraine, utilizes proquinazid as its primary active ingredient. Unlike conventional triazoles, proquinazid belongs to the quinoline class and employs a highly targeted mode of action. It prevents the development of powdery mildew (Erysiphe graminis) by disrupting the formation of appressoria — the specific infection structures fungi use to penetrate the host plant's epidermis. By neutralizing these structures before penetration occurs, the product effectively prevents the disease from establishing itself within the plant tissues of winter wheat and winter barley.

Dual-Action Protection Mechanism

Talius 20 stands out due to its unique physical and chemical characteristics:

• Gas-phase activity: A critical technical advantage where the fungicide redistributes itself in the vapor phase, allowing it to cover the entire canopy, including hard-to-reach areas and newly developed leaves that emerged post-application.
• Systemic & Contact synergy: The product provides a robust surface barrier (contact effect) while simultaneously entering the plant's cuticle to ensure long-term residual protection against secondary infections.

Application Standards and Field Performance

Designed for professional use, Talius 20 acts as a highly effective preventive tool. Its chemical formulation allows for excellent tank-mix compatibility with other crop protection products. Given its specific mechanism, it is best applied at the early stages of disease pressure.

Technical specifications: The application rate ranges from 0.15 to 0.25 L/ha. It is classified as a Hazard Class 3 product, requiring standard safety protocols. A maximum of 2 applications per season is permitted, with a mandatory 30-day pre-harvest interval to ensure compliance with quality and safety standards.
