potato fields miles away.<\/li>\n<li>Can cause severe losses in commercial potato production.<\/li>\n<li>Has forced commercial potato growers out of farming. This closes a business and stresses rural families and the local economy.<\/li>\n<\/ul>\n<h4><strong>Before planting, home gardeners can:<\/strong><\/h4>\n<ul>\n<li>Use healthy tomato transplants and certified seed potatoes, NOT potatoes from a grocery store.<\/li>\n<li>Discard potato seed that has sunken blemishes on the surface with rusty, granular discoloration in the flesh underneath.<\/li>\n<\/ul>\n<h4><strong>After planting, home gardeners can:<\/strong><\/h4>\n<ul>\n<li>Allow sufficient space between plants to allow the tops of the plants to remain dry.<\/li>\n<li>Protect the growing potato and tomato plants with products containing mancozeb, maneb, or chlorothalonil. These are available at garden centers and should be applied at seven-day intervals or as directed on the label. Local potato growers can also provide advice on spray timing.<\/li>\n<li>Check the plants regularly for the disease. If symptoms appear, pull the diseased plant and place it in a plastic bag. Discard the bag without opening it. DO NOT place the diseased plant into a compost pile or leave it in the garden. Both tomato fruit and potato tubers are quickly broken down when late blight attacks them. Non-infected potato tubers or tomato fruits, even if the plant is diseased, are usable.<\/li>\n<li>Check the harvested tomato fruit and potato tubers regularly as the disease can progress quickly. Discard infected fruit, plants or tubers in a sealed plastic bag.<\/li>\n<\/ul>\n<h3>Videos:<\/h3>\n<h4><strong>Identifying Late Blight, University of Maine (YouTube)<\/strong><\/h4>\n<div class=\"responsive-video\"><iframe loading=\"lazy\" title=\"Identifying Late Blight\" width=\"1268\" height=\"713\" src=\"https:\/\/www.youtube.com\/embed\/Tj9WShQ1nRU?wmode=transparent&amp;rel=0&amp;feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/div>\n<h4><strong>Managing Late Blight: Second in the Series, University of Maine (YouTube)<\/strong><\/h4>\n<div class=\"responsive-video\"><iframe loading=\"lazy\" title=\"Managing Late Blight: Second in the Series\" width=\"1268\" height=\"713\" src=\"https:\/\/www.youtube.com\/embed\/oA8Ixj-B_hk?wmode=transparent&amp;rel=0&amp;feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/div>\n<p>&nbsp;<\/p>\n<h4><strong>For further information, contact:<\/strong><\/h4>\n<ul>\n<li><strong>University of Maine Cooperative Extension:<\/strong> 1.800.287.1462<\/li>\n<li><strong>Maine Potato Board:<\/strong> 1.800.553.5516<\/li>\n<\/ul>\n<hr \/>\n<ul>\n<li>To Download and Print: <a href=\"https:\/\/extension.umaine.edu\/potatoes\/resource\/late-blight-gardener-alert\/\">Late Blight Gardener Alert (PDF)<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Late Blight Information for Every Gardener in Maine An effort of the Maine Late Blight Task Force, a cooperative effort of the University of Maine, the Maine Department of Agriculture, Food and Rural resources, and the Maine Potato Board.
