Sporangia release zoospores which require water for transport. Zoospores swim in water droplets until they encyst and infect the fruit. [6] Symptoms, beginning with fruit rot, may form within 24 hours. Chlamydospores are the pathogen's resting structure, which allows the disease to survive and overwinter in the soil.
Few varieties are resistant to the disease and none are immune, so rotating susceptible plants with non-susceptible ones like cereals is a practice positive to limiting soft rot infection. The control of specific insect vectors is also a good way of controlling disease spread in the field and in storage.
