Methods of inoculation and factors favorable for the infection of cacao by Monilia roreri
In studies conducted at the Tropical Experimental Station, Pichilingue, Ecuador, artificial inoculation tests were made with M. roreri on fruits and flowers of cacao (Theobroma cacao). Through the use of a new method for inoculating fruits, it was determined that pods may be infected at any age of development on the plant, but are more susceptible to Monilia attack in the earlier stages of development. Flowers are susceptible to fungus infection and symptoms appear later in the pods. The inoculation of flowers 6 hr after pollinization reduced fruit set; inoculation of flower buds did not produce the same effect. Cuprous oxide applied to inoculated flowers did not control the action of the fungus on fruit set and caused a reduction in fruit set on flowers not inoculated. When applied to flower buds, the fungicide caused dehiscence of the flowers at the time of opening.
