PLANT GROWTH AND DEVELOPMENT STIMULATOR Russian patent published in 2024 - IPC A01N59/16 A01N33/02 A01P21/00 B82Y99/00 

FIELD: agriculture.

SUBSTANCE: invention relates to plant growing, and concerns a plant germination, growth and development stimulator. Plant growth and development stimulant includes a solution of colloidal silver and polyhexamethylene biguanide or polyhexamethylene guanidine, or at least one salt of polyhexamethylene biguanide or polyhexamethylene guanidine, or polyvinylpyrrolidone, or carboxymethyl cellulose, characterized by that it further includes at least one amphoteric surfactant selected from the group, including N-(2-ethylhexyl)-iminodipropionic acid and its salt, N-octyliminodipropionic acid and its salt, N-talloalkyliminodipropionic acid and its salt, N-cocoalkyliminodipropionic acid and its salt, N-cocoalkylaminopropionic acid and its salt, aminocarboxylic acids R(OCH₂CH₂)_p[N((CH₂)_aCOOH)(CH₂)_b]_nNH_2-m((CH₂)_cCOOH)_m, in which R is cocoalkyl or talloalkyl, a=1 or 2, b=2 or 3, c=1 or 2, m=2, n ranges from 1 to 10, p = 0 or p ranges from 7 to 10, and salts thereof. Concentration of colloidal silver ranges from 10^-5 to 1 wt.%. Concentration of at least one amphoteric surfactant is from 10^-5 to 0.5 wt.%. Concentration of polyhexamethylene biguanide or polyhexamethylene guanidine, or at least one salt of polyhexamethylene biguanide or polyhexamethylene guanidine, or polyvinyl pyrrolidone, or carboxymethyl cellulose is from 10^-5 to 5 wt.%. Plant growth and development stimulator is used to stimulate plant growth and development by treatment of plant seeds or vegetative plants.

EFFECT: disclosed plant growth and development stimulator has aggregative stability of colloidal silver in the presence of electrolytes, high stimulating properties, stability in a wide range of storage temperatures.
