METHOD FOR STIMULATION OF GROWTH AND INCREASING IMMUNITY OF TOBACCO PLANTS TO FUNGAL PATHOGENS Russian patent published in 2023 - IPC A01G22/45 A01C1/08 

FIELD: agriculture.

SUBSTANCE: invention can be used in the technology of tobacco cultivation. The method involves pre-sowing soaking of seeds and treatment of seedlings in the main phases of their formation with a "Grow-B" growth-stimulating plant protection agent with a fungicidal effect, the active substance of which is natural triterpene acids isolated from fir wood greenery. Soaking the seeds is carried out in an aqueous solution of the drug with a concentration of 0.10-0.05% for 3-12 hours, seedlings are treated in the main phases of its formation ("ears" and "seedlings suitable for planting") with an aqueous solution of the preparation in the same concentration using a watering can with the consumption of the working solution of 1 l / m². The sowing of seeds is carried out in a nutrient mixture with the content of the main nutrients N₃₅P₃₀K₃₅ that make up 50% of the optimally required dose.

EFFECT: method provides for increased germination and germination rate of seeds, increased yield of high-quality standard seedlings, stimulation of its immune potential, reduced damage by mycopathogenic infection, reduced forcing period, increased survival of plants in the field, increased yield and quality of tobacco raw materials while maintaining environmental ecology.
