Propi 250 k.e.

Systemic Activity and Mode of Action

The fungicide "Propi 250 k.e." relies on propiconazole, a systemic active ingredient belonging to the triazole chemical class. Its primary technical advantage is its ability to rapidly inhibit ergosterol biosynthesis in fungal cell membranes. This process disrupts the structural integrity of the pathogen, causing the growth of the fungus to cease almost immediately upon contact and systemic absorption.

Formulation Efficiency

The emulsifiable concentrate (EC) formulation is engineered for high penetration capacity. Once applied, the compound moves acropetally (upward) through the plant tissues. This systemic transport is critical for protecting new vegetative growth that appears after the application. The active ingredient quickly crosses the leaf cuticle, providing both preventive and curative benefits against infection cycles.

Targeted Disease Management

The product is formulated to manage a diverse range of fungal diseases across several critical field crops:

• Cereals (Wheat, Barley): Exceptional efficacy against various rust species (stem, brown, yellow), as well as septoria and net blotch.
• Oilseed Rape: Essential for combating phoma, a disease that compromises stem health and structural integrity.
• Fodder Beet: Reliable control of cercospora to maintain leaf surface area and photosynthesis efficiency.

With an application rate of 0.4–0.5 L/ha, the product is highly concentrated and effective. Users should adhere to a maximum of 1–2 applications per season and maintain a 30-day pre-harvest interval (PHI) to ensure optimal safety and residue compliance. This systemic solution offers a reliable balance of immediate efficacy and sustained crop protection.
