Sunflower seed Aston (108 days, for Granstar, resistant to 7+ broomrape races) Economy

Aston (108 days) — an economical sunflower hybrid for stable oil content and protection against broomrape Sunflower Aston (108 days) — a medium-early high-yielding hybrid created for cultivation in intensive technologies and difficult phytosanitary conditions. It is distinguished by resistance to 7+ races of broomrape and to herbicides based on tribenuron-methyl (Granstar), which ensures effective cultivation even in regions where the parasite is widespread. An ideal solution for those who aim to obtain a stable yield and the maximum percentage of oil content in sunflower crops.

Purpose and application The Aston sunflower hybrid is recommended for commercial cultivation in the central regions of Ukraine with an intensive and moderately intensive farming culture. Thanks to its convenient packaging (1 seed unit — 150 000 seeds) it is suitable for commercial crop rotations. It is compatible with a protection system based on SU herbicides (tribenuron-methyl) and is also ideally suited for producing seed for oil.

Advantages of use Genetic resistance to 7+ races of broomrape (A–G) — reduces the risk of yield losses in areas affected by this parasite. Tolerant of active substances based on tribenuron-methyl: ease of integration into modern herbicide protection schemes. Seed already treated with highly effective fungicides and a complex of micro-fertilizers — a reliable start even in the stressful conditions of spring. A high level of resistance to diseases, drought and lodging — maximum technological reliability of the crop. Mechanism of protective action The hybrid has built-in genetic resistance to the most widespread races of broomrape (A–G), which substantially limits the negative influence of the parasite on the growth and development of the plants. Tolerance of preparations of the SU herbicide class (tribenuron-methyl) ensures the safety of applying the corresponding products on the crop without reducing yield. Comprehensive seed treatment with fungicides (carbendazim, metalaxyl-M) and micro-fertilizers guarantees an active start and a reduction in the influence of soil-borne and seed-borne diseases.

Features and unique properties A single two-line hybrid optimised for intensive cultivation systems. A high level of oil content — up to 55%. A balance of yield and adaptation: average yield — 37 c/ha, potential — 58 c/ha. Maximum indicators of resistance to the main diseases and to lodging — 9 points on a number of criteria. Improved factory preparation: fungicidal seed dressing, micro-fertilizers, polymer dye, convenient packing.

The optimum plant stand — is chosen depending on the soil type, the preceding crops and the level of moisture supply (usually 45–60 thousand/ha). The seed is fully ready for sowing; additional treatment before sowing is not required. The choice of herbicide scheme must take into account the hybrid's tolerance of tribenuron-methyl (under Granstar). Store the seed in a dry, ventilated room, at a temperature of up to +15°С and humidity of up to 60%. Do not allow direct contact with moisture, in order to preserve the sowing qualities and the germination energy. Key advantages Reliable protection against 7+ races of broomrape — minimisation of the risk of yield losses even on affected areas. Maximum indicators of oil content (up to 55%) and yield — effective use of the area. Full readiness of the seed for sowing: professional fungicidal treatment and micro-fertilizers for starting energy. A wide spectrum of disease resistance: high scores for the main pathogens and for lodging. The hybrid is adapted to modern herbicide cultivation technologies under Granstar. Why it is worth choosing Aston The Aston hybrid — a choice for progressive farmers who value a technological approach, stability and effectiveness. By purchasing this hybrid, you obtain an economically advantageous and agronomically predictable solution for modern conditions of sunflower production.
