When climatic conditions are suitable (temperatures range between 10\u00b0C and 33\u00b0C and humidity exceeding 50%), the cleistotes germinate and produce conidial spores that are transported by wind or rain. Conidial spores germinate on the leaves, and a germ tube emerges from them in the cell membrane. After penetrating the leaf, the mycelium develops and in turn produces conidia (spores) on the upper side of the leaves. This is known as the primary infection cycle.<\/p>\n\n\n\n<p>The resulting spores are spread in the field by wind or rain and infect healthy parts of plants.
