Escin compound inhibiting secretion system of phytopathogenic Gram-negative bacteria and biocontrol agent of plant diseases with this compound

摘要

The present invention relates to a plant disease control agent containing an acid component as an active ingredient which inhibits the secretory system of phytopathogenic Gram-negative bacteria. The acid compounds of the present invention can selectively inhibit the secretory system associated with the pathogenic induction of plants without affecting the growth of phytopathogenic gram-negative bacilli. Therefore, the eczynic compounds of the present invention are environmentally friendly plants for controlling plant diseases caused by gram- Can be used as an active ingredient of a disease inhibitor.
