R 11 ST 6 MI

Reliable Yields in Challenging Phytosanitary Conditions

The R 11 ST 6 MI sunflower hybrid from the French company Lidea is a strategic asset for agronomists managing fields with high pathogen risks. Developed by Rustica Semena and Semlima, this hybrid does more than deliver high oil content; it maintains yield potential in environments where conventional varieties succumb to disease pressure.

Protection and Field Strategy

The standout feature of this model is its compatibility with the Clearfield (Euro-Lightning) production system. This enables the integration of the hybrid into intensive weed control programs, targeting even the most persistent weed species without the risk of phytotoxicity. Post-emergence herbicide application ensures a clean crop, allowing the plant to dedicate its full biological resources to grain development.

• Phytosanitary Resistance: Strong tolerance to phomopsis and phoma makes R 11 ST 6 MI an excellent choice for humid regions, where rot diseases are the primary threat to seed quality.
• Operational Efficiency: Genetic resistance to the sunflower moth and white rot significantly reduces the need for mid-season fungicide applications, lowering overall production costs.

Practical application shows this hybrid excels under moderately intensive cultivation practices. With oil content reaching 50–55%, it is highly valued by both producers and processors seeking premium raw material. It is recommended for farms where crop hygiene and consistent performance are vital, even in challenging infectious environments.
