TOST

Prioritizing Fiber Quality in Demanding Environments

The 'Tost' flax variety is a specialized tool for producers focused on obtaining high-quality bast raw materials. Developed by breeders at the Siberian Federal Scientific Center for Agro-Biotechnologies of the Russian Academy of Sciences, this fiber flax is adapted to the climatic challenges of regions with short growing seasons and high infection pressure.

Biological Crop Protection

The primary practical value of 'Tost' lies in its genetic resistance to key flax pathogens: Fusarium wilt and rust. In intensive farming systems where these diseases can devastate yields, choosing this variety allows agronomists to:

• Reduce expenditure on fungicide applications.
• Minimize the risks of fiber quality loss due to fungal infections.
• Ensure stable yields during years with high moisture levels.

Agronomic Features and Application

Visually, 'Tost' is easily identified by its bright blue flowers. The main purpose for choosing this variety is fiber production. By adhering to planting regulations and harvesting at the early yellow maturity stage (when fiber content is peak and strength remains intact), 'Tost' delivers excellent results in long-fiber yield.

It is recommended for farms practicing crop rotation where flax returns to the field no more than once every 6-7 years. Given its Siberian origin, the crop handles temperature fluctuations at the start of the growing season exceptionally well, which is critical for early planting in cold soil.
