Abstract
The mechanochemical method of producing supramolecular complexes of tebuconazole (TBC) was used to obtain new complex agents of plant protection from pests and diseases of cereal crops. The use of chitosan, as well as licorice root extract, in these processes made it possible to obtain preparations with improved physicochemical and biological parameters. Under field conditions, the high biological efficiency of the composition of tebuconazole with chitosan against Puccinia recondita, Septoria nodorum and Blumeria graminis was shown with a single treatment at the beginning of heading of spring wheat plants, which led to an increase in grain yield by 0.55 t/ha, while the dose of tebuconazole fungicide was reduced by a factor of 5.5. The possibility of making similar spring wheat protection products based on the combination of chitosan with licorice root extract without the inclusion of tebuconazole is demonstrated. This increases the grain productivity of wheat by 0.54-0.6 t/ha.
