Sunflower OA 723

Technological potential of the OA 723 hybrid

The American breeding approach implemented by Winfield Solutions in the OA 723 sunflower hybrid is tailored for intensive farming conditions. The core technical feature is the genetic adaptation to the Clearfield (Euro-Lightning) protection system. Unlike conventional hybrids, OA 723 allows for the application of imidazolinone-based herbicides without causing phytotoxic stress to the plant, which is crucial for fields infested with broomrape and perennial weeds.

Agrotechnical characteristics and protection

• Metabolic resistance: The hybrid's genetic architecture ensures high selectivity to the herbicide’s active ingredients, blocking their negative impact on head development and seed formation.
• Immune status: Winfield Solutions' breeding program focuses on suppressing aggressive races of downy mildew, which reduces the need for heavy fungicide application during the growing season.
• Root system architecture: Deep root penetration ensures efficient nutrient and moisture uptake even under drought conditions, a hallmark of the climatic zones in the USA where the genetic material was developed.

The practical application of OA 723 is ideal for fields with high weed pressure where mechanical cultivation fails to provide effective control. Thanks to the predictable response to herbicide application, agronomists can utilize a stable application window, effectively minimizing risks of lodging or crop developmental issues.
