Cocoa white thread (015)
Pacific Pests, Pathogens and Weeds
- Worldwide distribution. In wet tropics. On cocoa and many other trees and shrubs. An important disease when cultural control operations are not done routinely.
- Fungal threads grow along branches, onto leaf stalks and blades, killing the leaves, which remain hanging in place attached by the threads.
- White toadstools occur occasionally in wet weather.
- Spread is by spores, and branches falling from shade trees onto cocoa beneath.
- Cultural control: prune out infected branches, along with the leaves, remove from the plantation, and burn them. Make regular 3-monthly inspections.
- Chemical control: none recommended.
