METHOD FOR APPLICATION OF FUNGICIDAL AGENTS IN INCREASING THE SURVIVAL RATE OF WINTER RAPESEED ON DARK GREY FOREST SOILS OF THE CENTRAL NON-BLACK EARTH REGION Russian patent published in 2022 - IPC A01N43/653 A01N43/92 C05G1/00 C05C1/00 

FIELD: agriculture.

SUBSTANCE: method for cultivating winter rapeseed on dark grey forest soils for the Central Non-Black Earth Region is characterised by tilling the soil after the predecessor - winter wheat, preparing seeds for sowing, performing autumn pre-sowing cultivation to a seed planting depth of 2 to 2.5 cm in order to form a seedbed, sowing with encrusted seeds using an SZT-3,6 seeding machine to a depth of 2 to 2.5 cm with a seeding rate of 1.0 million pcs./ha by a continuous row method, rolling the field with ring-toothed KZK-10 rollers immediately after sowing, and managing the crops in autumn; wherein first mineral fertilisers are applied at a dose of N₁₀₀P₆₀K₆₀ for cultivation before sowing winter rapeseed, then the crops are treated with the Karamba fungicide 1 l/ha before overwintering the winter rapeseed, when the plant reaches 4 to 5 true leaves in the rosette phase, and ammonium nitrate is applied in the spring as a top-dressing at a dose of N₆₀.

EFFECT: possibility for a fuller long-term protective effect of the new fungicide in the development of stem leaves of plants, for elimination if mineral deficiencies before sowing winter rapeseed, and for using an ammonium nitrate top-dressing in spring to reach high yields.
