Controlling agent for agricultural or horticultural bacterial disease

摘要

A controlling agent for agricultural or horticultural, which is less phytotoxic and which has considerable controlling effect against bacterial plant diseases, is provided by using bis(8-guanidinooctyl) amine or salts thereof as an active ingredient. By using, together with bis(8-guanidinooctyl)amine or salts thereof, other active ingredient of a controlling agent for agricultural or horticultural bacterial disease than these compounds, the controlling agent for agricultural or horticultural having an even higher effect is provided.
