In the method, first, the sample is added an aqueous solution containing N,N,N′,N′-Tetramethyl-1,4-phenylenediamine and 5-(2,4-disulfophenyl)-3-(2-methoxy-4-nitrophenyl)-2-(4-nitrophenyl)-2H-tetrazolium to provide a mixture. The aqueous solution has a pH of not less than 5.1 and not more than 6.5. Then, the mixture is irradiated with light having a wavelength of 400 to 500 nanometers to measure a first absorbance Ay of the mixture, and the mixture is irradiated with light having a wavelength of 500 to 800 nanometers to measure a second absorbance Ax of the mixture. If the value of Ay/Ax is not less than 1.5 or the mixture is orangey, it is determined that the sample contains at least one of Cercospora fungus and Pseudocercospora fungus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for determining whether or not sample contains Cercospora fungus or Pseudocercospora fungus","description":"The present invention provides a method for determining whether or not a sample contains at least one of Cercospora fungus and Pseudocercospora fungus.
