Sunflower L 31

Stable Yields Through Intensive Farming

The “L 31” hybrid is the professional choice for agronomists operating in areas with high infectious pressure and complex phytosanitary conditions. Developed by originator Igor Viktorovich Marin, this hybrid focuses on adaptability and resistance to imidazolinone herbicides. Utilizing this hybrid within a crop rotation allows for effective weed control, including stubborn species, through the “Clearfield” (Euro-Lightning) technology.

Agronomic Advantages

• Phytosanitary Shield: Strong resistance to key sunflower pathogens (downy mildew, white rot, and charcoal rot) eliminates the need for excessive fungicide applications.
• Operational Efficiency: Tolerance to Euro-Lightning simplifies field management, enabling control of broomrape and a wide spectrum of broadleaf and grass weeds in a single pass.
• Morphology: A mid-height plant (160–170 cm) with a large, flattened head that withstands wind pressure well, minimizing lodging risks during maturation.

Field experience shows that “L 31” performs exceptionally well on plots where the soil is contaminated with phomopsis, phoma, and powdery mildew. This makes it a “safety” choice for farms that have previously struggled with widespread crop rotting. The medium-sized, black-colored seeds ensure excellent flowability during drilling and uniform emergence, provided that planting depth guidelines are followed.
