Abstract
To create innovative complex seed protectants, a mechanochemical method for obtaining intermolecular supramolecular complexes of tebuconazole (TBC) was used. The use of polysaccharide arabinogalactan, glycyrrhizic acid and its disodium salt, as well as a dry extract of licorice root as substances forming supramolecular systems, including TBC molecules in their structure, made it possible to obtain preparations of seed disinfectants with improved ecological and biological properties. The obtained TBC-based compositions showed high efficacy against pathogenic microflora in laboratory and field conditions in the treatment of spring wheat and barley seeds, in suppression of the development of ordinary root rot, the absence of a retardant effect and a positive effect on the productivity of these crops. In addition, the compositions can reduce the rate of discharge of TBC up to 2 times.
