Pacific Pests, Pathogens and Weeds


  • Widespread distribution. Asia, tropical America, Oceania. On cocoa, tea, mango and black pepper. The fungus does not cause a disease.
  • Thin, dark threads grow over the leaves and branches, without infecting them. The leaves die naturally, but are held in place by the threads, making it look as if they have killed them.
  • Cultural control: none required on cocoa, although it is uncertain if the fungus is a pathogen of other crops.
  • Chemical control: none required.
