These fungi develop in the the vascular tissue of the tree. In response, the tree produces small gum blobs<\/abbr> that stop the growth of the fungus but also cut off the sap flow in the vascular tissue. Branches die as a result, after which the entire tree dies. Dut<\/wbr>ch Elm Disease is found in Europe, North America, Canada and New Zealand.
\nThe fungi are spread by the small and large elm bark beetle<\/a> (Scolytus scolytus<\/em> and S. multistriatus)<\/em> and by root contact between trees standing together.
\nThe beetle feed on the axillary buds of trees, infecting the tree with fungi. Once the trees are weakened by fungus, the beetles<\/a> lay eggs in a tunnel under the bark.
\nDut<\/wbr>ch elm disease is highly contagious. Moved Infected dead wood provides a new source of infection.[\/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_1677670950060{padding-left: 15px !important;}”]<\/p>\n
