Synergistic control: how the fungicide "Источник" works

The systemic fungicide "Источник" (produced by Zhenjiang Agrin Company Ltd.) utilizes a precise blend of two triazoles: triadimefon and flutriafol. This formulation is engineered to address fungal pathogens by targeting the biosynthesis of ergosterol—a fundamental component of the fungal cell membrane. By inhibiting the 14-alpha-demethylase enzyme, the product effectively halts the growth of fungi, providing both curative and preventive control.

Key components and their physical advantages

The choice of active ingredients in the emulsion concentrate formulation provides distinct systemic benefits:

• Flutriafol: Known for its exceptional mobility within the plant, it moves systemically via the xylem. This movement is vital for protecting new growth that develops after application.
• Triadimefon: Provides excellent performance against powdery mildew and oidium. Its ability to act within the vapor phase allows it to reach pathogens hidden in dense foliage or complex canopy structures, where standard contact fungicides might fail.

Field application and target pathogens

The product is designed for versatility, covering a range of crops including winter and spring wheat, winter barley, fodder beet, apple trees, and grapes. It targets significant threats such as septoria, fusarium, cercospora, powdery mildew, oidium, and scab. Being a systemic fungicide, it is highly effective in integrated pest management programs where long-lasting protection is required. With a Hazard Class 3 rating, the product is optimized for professional use, ensuring a reliable balance between biological activity and operational safety in various farming environments.
