Microenvironment and air bourne Moniliophthora roreri spore number in cocoa plantations shaded by three different leguminous tree species
Temperature changes, relative humidity and number of monilia (Moniliophthora roreri) spores in the air of experimental cocoa (Theobroma cacao) plantations shaded by three leguminous species (Gliricidia sepium, Inga edulis, Erythrina poeppigiana), were studied over the course of a day and during a year. Spore quantity in the air which varied strongly during the year (highest in april, corresponding to the period of lowest rainfall), was greatest under E poeppigiana and least under I edulis, The quantity of dispersed spores appears to be associated with micro-climatic differences under the three shade species; the highest temperature and lowest humidity occurred under the shade of E poeppigiana, which was pruned more frequently than the other shade species. The highest spore counts were registered between the hours of 8:00 and 14:00.
