Appressoria were latent in intercellular cleft and were latent until banana fruit were harvested.The development process of conidia of Colletotrichum musae on fruit was not distinct from foliage and stalk.Two pairs of PCR primers were designed according to the two especial fragment (357bp and 206bp) of Colletotrichum musae. Banana tissue culture seedling genomic DNA, banana anthracnose pathogen genomic DNA, mango anthracnose pathogen genomic DNA, rubber anthracnose pathogen genomic DNA,watermelon anthracnose pathogen genomic DNA, banana crown rot pathogen genomic DNA, stylo anthracnose pathogen genomic DNA, watermelon Fusarium wilt pathogen genomic DNA were extracted using SDS method.
