A sporangium can be produced, which generates a cyst and releases zoospores, or the oospore can create a germ tube which can directly penetrate and infect a host. This disease cycle is extremely dependent on water for dispersal, making greenhouses, irrigation systems, and hydroponics especially prone to spread of P. dissotocum.
The production of a sporangium can lead to the creation of a cyst that releases zoospores or an oospore that forms a germ tube, allowing it to directly infect a host. The disease cycle is highly dependent on water for its transmission, making environments with controlled water systems, such as greenhouses and hydroponics, particularly vulnerable to P. dissotocum.
