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

Aston (108 days) – a professional medium-early sunflower hybrid for intensive growing technologies, intended for the production of high-quality oilseed. Its main advantages are resistance to 7+ broomrape races (A–G), tolerance of tribenuron-methyl-based herbicides (Granstar 50 g/ha) and raised oil content – up to 55%. It is ideally suited to agricultural enterprises that work with sunflower in the central regions of Ukraine and are looking for the most effective seed material for a stable harvest.

Purpose and application Aston sunflower is recommended for sowing in the central and southern agro-climatic zones of Ukraine on farms that are introducing intensive farming systems and aim to obtain a stable yield with a high oil content. The hybrid combines excellently with modern soil-protection and weed-control systems thanks to its tolerance of Granstar herbicides.

Benefits of use Guaranteed economic efficiency– consistently high yield and oil content up to 55%. Reliable protection – full resistance to the new broomrape races (A–G) protects the harvest even on problem plots. Tolerance of SU-group herbicides (tribenuron-methyl) gives flexibility in choosing the weed-control system. Factory seed treatment with fungicides and micro-fertilizers – starting growth energy and initial protection against the main diseases. Intensive development type – even emergence and rapid head formation even in difficult agro-climatic conditions. Features and unique properties The main uniqueness of Aston lies in its powerful genetic resistance to 7+ broomrape races, which gives confidence in preserving the field and profitability even in regions with an increased phytosanitary load. Thanks to its tolerance of tribenuron-methyl (Granstar), the hybrid does not lose potential when integrated into herbicide technologies. The seed goes through multi-level treatment: fungicides (carbendazim, metalaxyl‑M), micro-fertilizers, a polymer dye for protection, stimulation of starting growth and ease of sorting.

Soil preparation and nutrition: be sure to follow the requirements of the intensive technology, provide full nutrition according to an agrochemical analysis. Herbicide application: use Granstar (up to 50 g/ha) according to the manufacturer's instructions, especially at the 2-8 leaf stage of sunflower. Crop protection: monitor diseases through the growing season; treated seed has initial protection against phytopathogens. Storage conditions: store the seed in dry premises, away from moisture and direct sunlight. Product advantages High oil content – up to 55% for maximum processing profitability. Genetic resistance to 7+ broomrape races (A–G) – protection of the harvest even under intensive field infestation. Tolerance of the herbicide Granstar – easy introduction of modern herbicide technology. High stable yield – an average level of 37 c/ha, potential up to 58 c/ha. Comprehensive seed treatment – factory protection with fungicides, micro-fertilizers and a safe polymer dye. Aston is a modern high-oleic sunflower hybrid that guarantees stability and economic efficiency in modern agricultural technologies. Choose innovative protection and yield for your farm!
