Sunflower cultivation always involves the risk of disease, which can significantly reduce yields and profitability. The most common diseases include white rot, phomopsis, and their impact is particularly noticeable in regions with high humidity or when agricultural techniques are not followed.
White rot (Sclerotinia sclerotiorum) is a fungal disease that affects sunflower stems and baskets, leading to plant death and reduced yields. Phomopsis manifests itself in the form of spots on leaves and stems, reducing photosynthesis and weakening the plant.
Eurosem hybrids are developed with resistance to these major threats in mind. They demonstrate:
- Resistance to white rot and phomopsis, which reduces yield losses in regions with high humidity: Ajax, Sumo 007, Stark 7+ Sumo.
- Tolerance to downy mildew (DM), controlled by the Pl6 gene in hybrids such as Grot, C-Pro 511, Thor 7+ Sumo, Arcona Sumo, Stark 7+ Sumo,
- Balanced yield and high oil potential even in difficult climatic conditions.
The use of disease-resistant hybrids minimises the use of fungicides and reduces crop protection costs while increasing yield stability. For farmers, this means less risk of loss and greater predictability of profit.
In addition to the natural resistance of hybrids, a comprehensive approach is important: proper crop rotation, timely treatment of seeds with fungicides and insecticides, moisture control, and agronomic measures. Eurosem provides agronomic support so that farmers can optimally utilise the potential of resistant hybrids and get the most out of their fields.
Choosing resistant sunflower hybrids is a strategic decision that reduces risks, increases profitability, and ensures stable yields. Eurosem hybrids have proven their effectiveness in various regions of Ukraine and Kazakhstan, making them a reliable choice for modern farmers.
