The low plant transpiration rates combined with an increase in water absorption by roots from the soil leads to increased cell turgor pressure, resulting in eruption of epidermal cells as the inner cells enlarge. Protrusion of the inner cells causes epidermal cells to die and discolor, resulting in a \u2019warty\u2019 appearance that can be misidentified as a disease. In addition to foliar symptoms on some hosts, many cucurbit crops develop wart-like protruberances on the fruit.<\/p>\n\n\n<div class=\"wsu-row wsu-row--quarters\" >\r\n    \n<div class=\"wsu-column\"  style=\"\">\r\n\t\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-medium is-resized\"><a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/pumpkin-edema-1l\/\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/pumpkin-edema-1L.jpg\" alt=\"edema symptoms on pumpkin-1\" class=\"wp-image-1301\" width=\"198\" height=\"264\" srcset=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/pumpkin-edema-1L.jpg 638w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/pumpkin-edema-1L-396x528.jpg 396w\" sizes=\"(max-width: 198px) 100vw, 198px\" \/><\/a><figcaption class=\"wp-element-caption\">Severe wart-like growths on a pumpkin caused by edema.<br><strong>Photo Source: <\/strong>Lindsey du Toit, Washington State University.<\/figcaption><\/figure><\/div>\n<\/div>\r\n\n\n<div class=\"wsu-column\"  style=\"\">\r\n\t\n\n<figure class=\"wp-block-image alignleft size-medium is-resized\"><a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/pumpkin-edema-2l\/\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/pumpkin-edema-2L-396x223.jpg\" alt=\"edema symptoms on pumpkin-2\" class=\"wp-image-1302\" width=\"198\" height=\"112\" srcset=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/pumpkin-edema-2L-396x223.jpg 396w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/pumpkin-edema-2L.jpg 850w\" sizes=\"(max-width: 198px) 100vw, 198px\" \/><\/a><figcaption class=\"wp-element-caption\">Close-up view of severe edema symptoms on a pumpkin.<br><strong>Photo Source:\n<\/strong>Phil Hamm, Oregon State University.<\/figcaption><\/figure>\n\n<\/div>\r\n\n\n<div class=\"wsu-column\"  style=\"\">\r\n\t\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-medium is-resized\"><a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/winter-squash-oedema-1l\/\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/winter-squash-oedema-1L.jpg\" alt=\"edema symptoms on squash-1\" class=\"wp-image-1303\" width=\"198\" height=\"149\" srcset=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/winter-squash-oedema-1L.jpg 850w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/winter-squash-oedema-1L-396x297.jpg 396w\" sizes=\"(max-width: 198px) 100vw, 198px\" \/><\/a><figcaption class=\"wp-element-caption\">Small but extensive symptoms of edema on a winter squash.<br><strong>Photo Source: <\/strong>Lindsey du Toit, Washington State University<\/figcaption><\/figure><\/div>\n<\/div>\r\n\n\n<div class=\"wsu-column\"  style=\"\">\r\n\t\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-medium is-resized\"><a href=\"https:\/\/mtvernon.wsu.edu\/path_team\/winter-squash-oedema-2l\/\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/winter-squash-oedema-2L.jpg\" alt=\"edema symptoms on squash-2\" class=\"wp-image-1304\" width=\"198\" height=\"149\" srcset=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/winter-squash-oedema-2L.jpg 850w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/31\/winter-squash-oedema-2L-396x297.jpg 396w\" sizes=\"(max-width: 198px) 100vw, 198px\" \/><\/a><figcaption class=\"wp-element-caption\">Close-up view of edema symptoms on the surface of a winter squash.<br><strong>Photo Source: <\/strong>Lindsey du Toit, Washington State University<\/figcaption><\/figure><\/div>\n<\/div>\r\n\n<\/div>\n\n\n<p><strong>On-Line Resources<\/strong>:<\/p>\n\n\n\n<ul>\n<li><a href=\"http:\/\/www.omafra.gov.on.ca\/IPM\/english\/cucurbits\/diseases-and-disorders\/oedema.html\">OEDEMA<\/a> &#8211;
