Fatores microclimáticos associados a incidencia de podridao parda em frutos de cacaueiro
Humidity, wind speed, air and pod temperatures were measured in a cacao plantation for 24 hour periods in April and October 1976. When the air temperature changed, the pod temperature lagged behind, giving a possible temperature difference of several degrees K. On 9 April the dew-point of the air increased rapidly between 5:00 am and 11:00 am being above the pod temperature from 6:00 to 9:00 am. Condensed water on the pod surface was present for 5 hours, giving conditions suitable for germination of zoospores of Phytophthora palmivora. On 6 October the dew-point of the air did not increase after 7:30 am and remained below pod temperature
