A characteristic feature of the disease is the formation of spots in concentric circles, resembling &#8220;targets&#8221;.<\/p>\n\n\n\n<p>In tomato fruits the spots are black and sunken, whereas in potato tubers they are brown and may extend over a large part of the fruit.<\/p>\n\n\n\n<p>In tomatoes, the symptoms are similar to those caused by an imbalance in nutrition between calcium and potassium.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Pathogen &#8211; Growth conditions<\/h2>\n\n\n\n<p>The fungus responsible for this disease is <strong>Alternaria solani<\/strong>.<\/p>\n\n\n\n<p>Infections start from crop residues or self-infected plants and are favored by low temperatures at which the spores germinate.

I perceive my self as always a student. I created kalliergo.gr back in 2010, charmed by the plants magical world. I am a Biomedical Engineer, holding a MSc degree on E-Business. For a living I help businesses to grow online. I am not an agronomist but wish I had also a degree on agronomy. I hope that you will find interesting and helpful information on KALLIERGO.","url":"https:\/\/www.kalliergo.gr\/en\/author\/ilias\/"}]}},"uagb_featured_image_src":{"full":["https:\/\/www.kalliergo.gr\/en\/wp-content\/uploads\/2012\/06\/astheneia-alternariosi-patatas-01.jpg",768,509,false],"thumbnail":["https:\/\/www.kalliergo.gr\/en\/wp-content\/uploads\/2012\/06\/astheneia-alternariosi-patatas-01-150x150.jpg",150,150,true],"medium":["https:\/\/www.kalliergo.gr\/en\/wp-content\/uploads\/2012\/06\/astheneia-alternariosi-patatas-01-300x199.jpg",300,199,true],"medium_large":["https:\/\/www.kalliergo.gr\/en\/wp-content\/uploads\/2012\/06\/astheneia-alternariosi-patatas-01-768x509.jpg",768,509,true],"large":["https:\/\/www.kalliergo.gr\/en\/wp-content\/uploads\/2012\/06\/astheneia-alternariosi-patatas-01.jpg",768,509,false],"1536x1536":["https:\/\/www.kalliergo.gr\/en\/wp-content\/uploads\/2012\/06\/astheneia-alternariosi-patatas-01.jpg",768,509,false],"2048x2048":["https:\/\/www.kalliergo.gr\/en\/wp-content\/uploads\/2012\/06\/astheneia-alternariosi-patatas-01.jpg",768,509,false]},"uagb_author_info":{"display_name":"Ilias Antonopoulos","author_link":"https:\/\/www.kalliergo.gr\/en\/author\/ilias\/"},"uagb_comment_info":0,"uagb_excerpt":"Early blight affects the stems, leaves and fruits of tomatoes, potatoes, eggplants and peppers.
