Sunflower SF 564

Reliable Weed and Broomrape Control Strategy

Choosing the SF 564 hybrid by Syngenta is a strategic move for farming operations utilizing the Clearfield production system. The application of imidazolinone-based herbicides (Euro-Lightning) provides exceptional control over a wide spectrum of weeds and all known races of broomrape (Orobanche). This makes SF 564 an indispensable asset for intensive crop management.

Agronomic Profile and Field Performance

With a vegetation period of 100-110 days, SF 564 falls into the mid-early maturity group. This flexibility is critical for logistics, as it allows for timely harvesting and optimal preparation of fields for subsequent winter crops. A stable oil content of 45-50% is a benchmark for this segment, ensuring high demand and attractive pricing from crushing facilities.

Disease Resistance and Stress Tolerance

The Swiss breeding program at Syngenta focuses on robust field health. SF 564 exhibits significant resistance levels to the most common sunflower pathogens, reducing the need for aggressive fungicide applications:

• Downy Mildew (Peronospora): reliable systemic protection.
• Phomopsis: improved stem integrity throughout the maturation phase.
• Phoma: reduced risk of stalk lodging and head decay.

These traits ensure that the yield potential is preserved, even under high disease pressure, providing farmers with peace of mind during the critical growth stages.

Why Growers Choose SF 564

As a simple hybrid, SF 564 offers excellent uniformity in growth and height. This uniformity is a major advantage for harvest operations, reducing header losses and simplifying grain cleaning. Its strong seedling vigor allows the crop to establish quickly and suppress weed competition effectively. For growers seeking a predictable and resilient hybrid, SF 564 is a proven solution that balances yield performance with management convenience.
