Lumisena

Reliable protection against downy mildew

When it comes to seed treatment, the cost of an error is sparse emergence and direct yield losses. In my experience, using Lumisena from Corteva has become a definitive solution for controlling downy mildew (Plasmopara halstedii) at the early stages of vegetation. Unlike older-generation fungicides, this product features oxathiapiprolin — a molecule that acts at the cellular level, effectively blocking pathogen development before it can damage the seedling.

Operational experience and process economics

As an operator, I prioritize predictability. This systemic fungicide comes as a flowable suspension concentrate, which is critical when working with seed treatment machinery. The product mixes easily, does not clog nozzles, and, importantly, provides uniform coverage on the seed coat without causing sticking in the seeder hopper. My practice shows that a dosage of 0.5–1.0 L/t is sufficient to cover the crop’s needs for protection against downy mildew at the start. A key point: a single application is enough to provide a long-lasting effect.

Practical nuances

• Processability: Due to its consistency, the product is easy to dose and ensures a steady flow in the treatment system.
• Systemic action: The active ingredient penetrates the seedling tissues, protecting the plant from within, which is a major advantage in cold or wet soil conditions.
• Safety: The product is classified as hazard class 3, which is standard for high-quality agrochemicals, but requires following basic safety measures when handling treatment equipment.

For an agronomist, this is a convenient tool: you treat the seeds before sowing and resolve the problem of the most dangerous seedling disease for weeks to come. Stable performance without the need for additional operations in the field is the primary indicator of Lumisena's efficiency.
