These soft-bodied plant suckers typically are found on the underside of hop leaves where they feed off the phloem of the plant. While feeding, aphids secrete a substance called \u201choney dew\u201d that contains excess sugars. If honey dew is secreted in hop cones, the perfect conditions are provided for sooty mold to grow. Plant productivity can be reduced by aphids feeding, but the bigger concern is that aphids can cause direct damage to the cone, and the decreased cone quality and appearance from sooty mold reduces cone marketability.<\/p>\n<p>&nbsp;<\/p>\n<p>Please be sure to closely monitor hops that are remaining in the field to decide if they should be harvested early to avoid or minimize damage from aphids.<\/p>\n<p>For more information about hop yard management in general, please visit our website (<a href=\"http:\/\/www.uvm.edu\/extension\/cropsoil\/hops\">http:\/\/www.uvm.edu\/extension\/cropsoil\/hops<\/a>), and for more information about the hop aphid and its management, check out the following article: <a href=\"http:\/\/www.uvm.edu\/extension\/cropsoil\/wp-content\/uploads\/Hop-Aphid1.pdf\">http:\/\/www.uvm.edu\/extension\/cropsoil\/wp-content\/uploads\/Hop-Aphid1.pdf<\/a>.\u00a0 And remember, keep calm and hop on\u2026<\/p>\n<p>Here is a picture of hop aphids and sooty mold on hop cone (http:\/\/www.homebrewtalk.com\/showthread.php?t=80510)<\/p>\n<p><a href=\"http:\/\/blog.uvm.edu\/hoppenin\/files\/2017\/09\/hop-cone-with-sooty-mold.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-3279\" src=\"http:\/\/blog.uvm.edu\/hoppenin\/files\/2017\/09\/hop-cone-with-sooty-mold-300x300.jpg\" alt=\"\" width=\"200\" height=\"200\" srcset=\"https:\/\/blog.uvm.edu\/hoppenin\/files\/2017\/09\/hop-cone-with-sooty-mold-300x300.jpg 300w, https:\/\/blog.uvm.edu\/hoppenin\/files\/2017\/09\/hop-cone-with-sooty-mold-150x150.jpg 150w, https:\/\/blog.uvm.edu\/hoppenin\/files\/2017\/09\/hop-cone-with-sooty-mold.jpg 512w\" sizes=\"auto, (max-width: 200px) 100vw, 200px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; The hop harvest is well underway in the Northeastern U.S., but growers are reporting high aphid populations on hops yet to be harvested.
