Abstract
A new efficient preparation with the broad range of action was developed on the basis of the aqueous solution of larch extract with the addition of a salt of 2,4-dichlorophenoxyacetic acid with bisamine and the extract of lichens of Usnea genus. The activity of this preparation is comparable with that of chemical fungicides. The preparation suppresses the development of mycosis and increases the productivity of spring wheat.
