The growth status of pathogens in tea leaves was assessed using a stereoscopic fluorescence microscope (Olympus SZX16, Tokyo Japan), and the total infected area was measured using image analysis software (Olympus Cellsens Standard, Tokyo, Japan). Tea leaves inoculated withNeopestalotiopsis sp. and C. gloeosporioides were placed in 4-mL centrifuge tubes with FAA fixed solution (G1103, Servicebio®, Wuhan China); sent to Wuhan Seville Biotechnology Co., Ltd. for fluorescent wheat germ agglutinin (WGA) staining; and photographed with a fluorescence microscope.
