FIELD: chemistry.
SUBSTANCE: invention relates to agriculture. A plant growth and development regulator based on adducts of auxins with a mixture of C50-C92 fullerenes contains the following, wt %: an adduct of auxin with a mixture of C50-C92 fullerenes - 0.0001-0.00001, water - the balance. The method includes carrying out a chemical reaction between a mixture of C50-C92 fullerenes and different auxins. The chemical reaction is carried out with acidation with sulphuric acid in a binary system of organic solvents at 58-60°C. Separation of synthesis products is carried out with distilled water heated to 100°C, followed by preparing aqueous solutions with a defined concentration based on the separated water-soluble fraction of the obtained mixture of adducts.
EFFECT: invention enables realise said purpose.
