FIELD: agriculture. SUBSTANCE: method involves the grinding elemental sublimated highly-dispersed sulfur to the particle size 1-10 mcm in oily medium, in inert medium, at 70-100 C for 20 min. Oily medium: fraction of petroleum residues at b. p. ; sublimated highly-dispersed sulfur: sulfur obtained after hydrogen sulfide removal from petroleum gases. Inert medium is made by exogas containing carbon oxide and hydrogen, or exhausted gas in conversion process containing carbon oxides and nitrogen. Obtained preparation has 20-40 wt.-% sulfur as 0.1% aqueous suspension used for plant spraying. Method provides high stability of obtained dispersion, its 90-93% fungicidal effect. EFFECT: improved properties, enhanced fungicidal effect, decreased time for preparing. 4 cl
