PROBLEM TO BE SOLVED: To obtain a safe and economic agent for preventing and/or treating disease damages in place of conventional fungicides for field crops, and to provide a method for preventing and/or treating disease damages using the same. SOLUTION: The method for preventing and/or treating disease damages comprises spraying a solid agent composed of one or more kinds selected from the group consisting of zeolite, montmorillonite, diatomaceous earth and silica gel or a solution obtained by diluting the solid agent with water on parts to cause disease damages of a field crop or parts caused by disease damages to promote drying of the sprayed parts. Consequently, germination of spores and growth of mycelia are inhibited, activation of already grown mycelia and injuries is controlled and expansion of disease damages is prevented. When the agent is sprayed on parts liable to be infected, a coating film is formed and not only the parts are prevented from coming into contact with disease germs and spores but also drying is promoted and occurrence of disease damages is prevented.
