Sunflower VK 21 IMI

Clearfield Technology from the VNIIMK Breeding Center

The selection work of the VNIIMK Federal Scientific Center is focused on environmental adaptability, and VK 21 IMI is the market answer to the challenge of hard-to-control weeds. This hybrid is specifically engineered for the Clearfield system, providing farmers with a robust tool to manage broomrape and grass weeds without the risk of phytotoxicity to the crop itself.

Resistance to Pathogens

The primary strength of VK 21 IMI lies in its targeted resistance to rot diseases. In humid conditions, where white and gray rot can reduce yields by up to 30%, this hybrid maintains high tolerance, preserving the integrity of the seed head. Additional protection against rust makes it a reliable choice for regions with volatile temperature patterns.

Who Should Choose This Hybrid?

• Growers in regions with heavy weed pressure where standard herbicide programs fail.
• Farmers prioritizing yield stability in intensive farming systems.
• Operations that need to ensure clean fields while minimizing mechanical inter-row cultivation.

While the hybrid is highly effective, it requires strict crop rotation management due to the soil persistence of the imidazolinone-based herbicide. This is a choice for professional agronomists who plan their field operations with a long-term view of soil chemistry and health.
