This disease is caused by a specialized fungus that infects a specific host and does not infect any other host. Therefore, you always find the names of diseases in downy mildew followed by the name of the host, such as downy mildew in cucurbits, onions, corn, etc. The fungus is an obligate parasite that only lives on plant cells, where it sends suckers into the cells to absorb its food.

The infection begins after it is transmitted from an infected plant to a healthy plant and then enters the plant tissues. The oospores are found on previous crops in the winter before they are transmitted to healthy plants.<\/strong><\/p>\n\n\n\n<p><strong>Symptoms appear as pale yellow spots that then turn yellow and then brown. On the lower surface, they are accompanied by white to gray fluffy growths. After the disease develops, the spots unite to cover the entire surface of the leaf. The infection is not limited to the leaves, but extends to the young stems and fruits.<\/strong><\/p>\n\n\n\n<p><strong>On the stems, the symptoms are brown lesions, then white fuzz appears on these spots, and the stems become thin and easy to break. As for the fruits, brown, marble-like spots appear, soft rot appears, and they become unmarketable.<\/strong><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"687\" height=\"365\" src=\"https:\/\/worldofplants.ai\/wp-content\/uploads\/2024\/03\/word-image-80853-1.png\" alt=\"Cigar Float Rot Disease in Bananas - Plant World\" class=\"wp-image-80862\" title=\"Cigar Float Rot Disease in Bananas - Plant World\" srcset=\"https:\/\/worldofplants.ai\/wp-content\/uploads\/2024\/03\/word-image-80853-1.png 687w, https:\/\/worldofplants.ai\/wp-content\/uploads\/2024\/03\/word-image-80853-1-300x159.png 300w\" sizes=\"auto, (max-width: 687px) 100vw, 687px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%D8%A7%D9%84%D8%B8%D8%B1%D9%88%D9%81_%D8%A7%D9%84%D9%85%D9%86%D8%A7%D8%B3%D8%A8%D8%A9_%D9%84%D8%A7%D9%86%D8%AA%D8%B4%D8%A7%D8%B1_%D9%85%D8%B1%D8%B6_%D8%A7%D9%84%D8%A8%D9%8A%D8%A7%D8%B6_%D8%A7%D9%84%D8%B2%D8%BA%D8%A8%D9%8A\"><\/span><strong>Suitable conditions for the spread of downy mildew<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>For the spread of downy mildew on plants, appropriate weather conditions must be present, which correspond to cold and moderate weather.
