Method for determining whether a test sample contains phytopathogenic fungi

摘要

A method for determining whether a test sample contains a phytopathogenic fungus, comprising the steps of: (a) arranging a test sample on a front surface of a substrate having a through-hole; Provided on the back surface thereof, the cellulose film has no through hole, and has a thickness of more than 2 micrometers and not more than 3.7 micrometers, and the through hole of the substrate is (B) a step of allowing the test sample to stand, (c) a step of observing the back surface of the cellulose film, and (d) a cellulose film. Determining that the test sample contains a phytopathogenic fungus if a fungus penetrating the cellulose film is found on the back surface of the test sample.
