It’s widespread worldwide.
\nConference<\/em> and Doyenné du Comice<\/em> are very susceptible to Pear Brown Spot. The fungus hibernates on infested fallen leaves. On this leaf, fruiting bodies develop that spread spores. This spread occurs during the day in humid and sweltering weather, as high temperatures and a long leaf wet period<\/a> are required to infect leaves and fruit. It takes several weeks for the first symptoms of the infection to appear. In practice, this is early July (leaf) and late July\/early August (fruit).
\nDark brown, black spots develop on the leaves. These spots have a distinctive V-shape. The midrib of the leaf is usually black. Eventually, the whole leaf turns black, after which it falls off. On the ripening fruit, one on several sunken black spots develop, often with a red rim around it. Underneath these spots, the flesh rots away. Rotting continues even during storage.<\/p>\n

Stemphylium vesicarium<\/em> causes Stemphylium purple spot on asparagus<\/a> and fern.[\/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_1705405123166{padding-left: 15px !important;}”]<\/p>\n
