Sunflower GONZALO SH

Why "Gonzalo ST" is a strategic choice for your farm

In the face of climate instability and high field disease pressure, selecting a hybrid from German breeder Strube is more than just a purchase—it's a strategic decision. "Gonzalo ST" is a classic simple sunflower hybrid that prioritizes biological resilience over marketing claims.

Crop health as the foundation for yield

The key differentiator of this hybrid compared to its peers is its robust phytosanitary profile. Strube breeders have focused heavily on complex resistance to critical diseases that can strip away up to 30% of a harvest annually. By choosing "Gonzalo ST," you effectively mitigate risks associated with:

• Verticillium wilt and Sclerotinia;
• Downy mildew;
• Phomopsis and Phoma.

This natural "shield" allows the plant to channel all its energy into head development rather than fighting off infections.

Biological performance

With a vegetation period of 110-120 days, this hybrid falls into the medium-early category. It hits the "sweet spot": it accumulates solid oil content (45-50%) while remaining plastic enough to mature before heavy autumn rains, ensuring a high-quality, dry harvest. The large seed size, combined with high germination energy, guarantees uniform stands even in suboptimal sowing conditions.

Who is this hybrid for?

"Gonzalo ST" is a perfect match for farms employing conventional tillage looking for predictable performance. It is an excellent choice for regions with high infection pressure where soil and climate conditions typically provoke root and stem rot. For growers who value German breeding quality and seek a balance between stability and oil yield, Strube provides this robust tool.
