FIELD: agriculture.
SUBSTANCE: invention is related in particular to compositions for seed treatment. Composition for pre-sowing treatment of seeds of grain crops contains a 0.01% aqueous solution of [N,N-tetramethylmethylenediamine oxalic acid] copper sulphate pentahydrate and a 0.01% aqueous solution of the cultural liquid of the mycophilic fungus Hypomyces odoratus VKPM F-242 in mass ratio 1:1.
EFFECT: proposed composition for pre-sowing seed treatment has a combined fungicidal and growth-regulating effect, high biological activity at a low consumption rate, and provides increased yields without chemical weeding of fields and additional application of mineral fertilizers.
