Black pod disease uncertain due to unconvincing results from an experiment that collected some spores in the air using the volumetric spore trap, where a small amount of spores were found in the trap. Conversely, the dispersal of inoculum via rain is considered an effective mechanism in spreading the inoculum. It was assumed that under close canopy, less water will reach the sporulating pods to spread the inoculum, however, rain drops from leaves and branches could also splash the inoculum to the surroundings. Infected pods laying on the ground or litter could also spread the inoculum, yet greater infection was observed on pods
