Abstract
Expediency of the application of results achieved in medicine, in the development of nanopharmaceutical materials with sharply increased antimicrobial activity, for plant cultivation was observed. It was established that these preparations provide plant protection against pathogens and unfavourable effects of abiotic nature. The stimulating action of bismuth and silver nanopreparations on the length of germs and roots of spring wheat exceeds the reference level by a factor of 1.2-1.3. The fungicide action of nanopreparations decreasing the development of the disease (root rot) by a factor of 2-4 was discovered. Optimal concentrations and standards of bismuth nanopreparation concumption for industrial tests in cereal production were proposed. Biologically active nanopreparation exceeds important seed disinfectants in efficiency, which opens the outlooks for import substitution in this area.
