The origin of the fungus is in the Andes. Meanwhile, the fungus is found all over the world.
\nSynchytrium endobioticum<\/em> does not form a fungus phloem but sorals<\/a>, in which spores are formed. The spores invade the epidermal cells of potatoes in spring and cause growths that swell into warts. The infected cells divide, creating more and more warts. In severe infestations, the warts grow into cauli<\/wbr>flower-like lumps
\nWet soils with a soil temperature of at least 8°C are required for the development of the pota<\/wbr>to wart desease. Summers with average temperatures of 18°C or below, winters below 5°C and annual precipitation of 700 mm and more are the conditions under which the fungus develops.<\/p>\n

In autumn, the warts rot away and release ‘resting’ spores. These spores rest in the soil and retain their germination capacity for up to forty years. The spores survive 11-12 hours survival at 100°C, composting for 12 days at 60-65°C and pasteurization for 90 minutes at 70°C. The spores also survive the way through the digestive system of animals that have eaten contaminated potatoes.<\/p>\n

If wart disease is detected on a plot, that plot is declared infected and no potatoes may be grown for a long time until the plot have been found free of the disease .
\nWart disease is a quarantine disease (EU), which is subject to strict legal regulations. Similarly, no other planting material (e.g. bulbs<\/a>, trees and perennials) may be grown on an infected plots – anything to prevent the spread of the fungus.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=”yes”][vc_column width=”1\/3″][vc_custom_heading text=”Where to find” font_container=”tag:h4|text_align:center|color:%23ffffff” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal” css=”.vc_custom_1537946500082{background-color: #536895 !important;}”][vc_column_text el_id=”entrytxt” el_class=”entrytxt” css=”.vc_custom_1669628572045{padding-left: 15px !important;}”]<\/p>\n
