[1] Trachysphaera fructigena primarily affects banana (cigar-end rot), coffee, and cocoa but is also associated with Mimusops elengi, M. commersoni, and avocado (Persea americana).

[1][4] On bananas, the oomycete causes cigar-end rot, forming ash-grey, wrinkled lesions at the flower end, which can progress to black necrosis and mummification during storage or transport.

On cocoa, it infects wounded pods, creating brown spreading lesions with dense, coarse-textured conidial masses that turn pinkish-brown.

The oomycete produces thick-walled conidia in fruit cavities, resembling chlamydospores, though their germination remains unobserved.

Sexual reproduction involves oogonia characterized by irregular sac-like outgrowths and amphigynous antheridia surrounding their stalks.

[2][5] Cultural practices, such as bagging in bananas and inflorescence binding in plantains, have consistently proven effective in reducing the percentage of infected bunches, even under conditions favorable to disease development.
