The invention relates to a primer for detecting orchid colletotrichum gloeosporioides molecules and a using method of the primer, which is specially used for detecting orchid colletotrichum gloeosporioides specific molecules and belongs to the fields of detection, identification and prevention and treatment of crop diseases. A pair of specific primers of orchid colletotrichum gloeosporioides comprising an upstream primer P1:5'-GGCCTCCCGCCTCCGGGCGGGTC-3' and a downstream primer P2:5'-TGAGGGCCTACATCAGCT-3' are subjected to polymerase chain reaction (PCR) amplification and agarose gel electrophoresis and can specifically amplify a specific amplification product with the segment length of 304bp in a plant infected with orchid colletotrichum gloeosporioides with pure DNA and germs and a culture medium. The specific molecule detection primer and the using method thereof can be used for detecting the orchid colletotrichum gloeosporioides in the plant infected with the orchid colletotrichum gloeosporioides and the culture medium quickly, sensitively and specifically, can also be used for performing early diagnosis on field diseases and monitoring and identifying germs, and provides reliable technological and theoretical basis for preventing and treating diseases caused by the orchid colletotrichum gloeosporioides.

A method of controlling anthracnose caused by Colletotrichum on tropical fruits, tropical fruit plants or cultivars or plant parts or locus thereof is described. The method comprises the steps of contacting the tropical fruit plant or cultivar in need of treatment with an agrochemical composition comprising an effective amount of a guanidine or a salt and / or solvate thereof. The contacting step may be repeated one or more times at a fixed interval. The guanidine may be dodine, iminoctadine trialbesilate, iminoctadine triacetate, guazatine, salts and / or solvates of any of the foregoing and combinations of one or more of the foregoing.
