Research on Cocoa Diseases in Ecuador: Past and Present

Resumen

Abstract The history and importance of cocoa diseases in Ecuador are discussed and the biology of the two more important pathogens is described. Chemical methods offer few prospects for economic control. Cultural control appears ineffective in reducing infection by Crinipellis perniciosa (Witches' broom) but there are possibilities of a partial control of Monilia roreri (Monilia pod rot) by cultural methods. Manipulation of the crop to escape infection has shown promise in reducing pod losses from both diseases.
