Previcur Energy 840 SL

Dual-action protection for your seedlings

In the fungicide market, Previcur Energy 840 SL by Bayer AG occupies a unique position. Its primary advantage over standard fungicides lies in the synergy of two active ingredients: propamocarb and fosetyl aluminum. While most fungicides either provide surface protection or move through the plant's vascular system, this product does both, simultaneously stimulating the crop’s natural immune response.

Why agronomists rely on this formulation

• Comprehensive action: Propamocarb hydrochloride effectively blocks fungal spore development, while fosetyl aluminum not only suppresses pathogens but also signals the plant to boost its natural defense mechanisms.
• Optimal for early stages: The fungicide is essential for greenhouse tomato and cucumber cultivation, providing robust defense against "damping-off" (root rot) during the most vulnerable early growth phases.
• Systemic reach: It is rapidly absorbed by the root system, ensuring protection even for parts of the plant not directly covered during application.

Application insights

To achieve maximum efficiency, it is crucial to follow the protocol: the maximum number of applications is limited to 2–3. Due to its high efficacy, the pre-harvest interval is minimal, ranging from 1 to 3 days. However, users should note that it is a Class 3 hazard substance, requiring proper safety measures during use in enclosed environments. A strong point is its stability in high-humidity conditions, which is critical for controlling downy mildew in cucumbers. A limitation is the need for precise dosage control (1.5–3 L/ha), as excessive concentrations can cause stress in young, sensitive seedlings.
