FIELD: biotechnology and agriculture.
SUBSTANCE: group of inventions relates to biotechnology and agriculture, in particular to two new compounds of the fusaricidin type. A cyclodepsipeptide of Formula I for phytopathogenic fungi control, strains of Paenibacillus sp. DSM 26969, DSM 26970 and DSM 26971 intended for this cyclodepsipeptide preparation and their application for phytopathogenic fungi control are proposed. A composition of this cyclodepsipeptide, a whole culture liquid, or a cell-free extract of these strains, demonstrating antagonistic activity against pathogenic plant fungi, are also proposed.
EFFECT: invention also relates to a method for controlling or suppressing plant pathogens or preventing phytopathogenic infections by using a composition of new compounds such as fusaricidin.
