[Epidemiology of anthracnosis and eye spot disease, conclusions for its prognosis of occurrence and its control in the Republic of Cuba].

Abstract

The course of attacks by anthracnosis and by the eye spot disease on branches, leaves, and fruits of Coffea arabica L. were investigated in Cuba. The daily precipitation and the shading are most influential for both diseases. There are marked differences in the attacks between the rainy season (highest attacks) and dry season (decreased attacks). Lack of shading increases the susceptibility of the plants to the eye spot disease. Under the conditions in Cuba, unshaded plantations exhibited an increased occurrence of anthracnosis. In order to predict the occurrence of anthracnosis, it is necessary to know the seasonal course of the sporulation capacity of the agent on the branches, for the eye spot disease to know the course of attacks on the leaves. The possibilities are discussed of controlling the two diseases.
