• Studies in Sicily have shown optimum time for oospore germination is between the end of February and the middle of March.
• This oospore will function as a survival structure for the pathogen over the winter, and serve as the primary inoculum the following spring.
• The survival structure is an oospore, which is the result of the karyogamy of two haploid gametes (the oogonium and antheridium).
• In oomycetes, the zygote forms through the fertilization of an egg cell with a sperm nucleus and enters a resting stage as a diploid, thick-walled oospore.
• An oospore is a thick-walled sexual spore that develops from a fertilized oosphere in some algae, fungi, and oomycetes.

• A haploid nucleus (gamete) from the antheridium will then be transferred through the fertilization tube into the oosphere, and fuse with the oosphere’s haploid nucleus forming a diploid oospore.
• The zygote produced is named an oospore.
• The storage material is starch, except in the oospore, where oil also occurs.
• "Phytophthora cactorum" can be identified by examining oogonia, antheridium, oospore, and sporangia structure.
• Antheridia will give one male nucleus to each eggs in oosphere then become diploid oospore.

• Once infection season comes to an end, sexual reproduction occurs to form an oospore.
• It has a spherical oogonium up to 25 µm in diameter, with an oospore that almost fills the oogonium.
• "Phytophthora" zoospores require water to germinate from the oospore, and can migrate by themselves through waterlogged soil.
• After fertilization, the zygote develops into an oospore.
• These sporangia germinate by producing zoospores with two flagella that help with zoospore movement.

• Over winter in the soil, oospores survive and wait for spring.
