Black pod disease: the future
This contribution is based on a report (which is to be circulated) prepared at the request of the Cocoa, Chocolate and Confectionery Alliance, after visiting plantations and/or laboratories in Nigeria, Cameroon Republic, Ghana, Ivory Coast, Bahia (Brazil), Trinidad, Jamaica, Costa Rica, California and Washington, D.C. (U.S.A.). Increased bean yields now in sight may bring increased losses from black pod (Phytophthora palmivora) but may also make the cost of controlling the disease worthwhile. Gaps in knowledge of the epidemiology of the disease, sources of infection and mode of spread, greatly hinder economic control by crop hygiene and fungicides. More knowledge of the mechanism and inheritance of resistance in the plant, and of the genetics of the fungus, with its races and mating type distribution, is needed to aid the plant breeding programme. Recommendations include: establishing an International Black Pod Research Advisory Committee; provision of a plant pathologist to develop and use standardized screening techniques with material of the collections at Turrialba; provision of two plant pathologists at a cocoa research centre to collaborate in studies on epidemiology and on the design of field experiments on fungicide spraying; provision (probably at the same centre) of a fungal geneticist to work on genetics and races of P. palmivora, keeping in close touch with relevant work at other centres
