The humid weather that is associated with this pathogen and all other black pod disease pathogens is needed as the sporangia forms and starts distributing spores through rainfall, splashing water, and running water. With this pathogen spreading behavior needing water is why there is almost always a spike in the prevalence of the disease shortly after the rainy season. The spread of infection to pods above bare soil was shown to be greater relative to pods above litter. The reason for this is due
