Abstract: This paper describes the synthesis of chitosan nanoascorbate Bombyx mori based on low molecular weight chitosan (LMWC) by the suspension method. Its physicochemical and antimicrobial properties against Fusarium oxysporum , which causes diseases of mulberry trees, have been studied. The resulting chitosan nanoascorbate based on low molecular weight chitosan has a larger suppression zone compared to all variants against the culture of Fusarium oxysporum mulberry and melon, which makes it possible to use it in presowing seed treatment at a ratio of LMWC:AA components 4:1. It was found that when wheat seeds were treated with chitosan nanoascorbate, the incidence of smut fungus decreased by 6.6 and 2.4 % compared to the control and the standard, respectively. The effect of the ratio of the components of chitosan (CS) and ascorbic acid (AA) on the formation of chitosan nanoascorbate (CSNA) was determined. IR spectroscopy established the structural characteristics of chitosan nanoascorbate Bombyx mori .
