in Rye"},"content":{"rendered":"<p style=\"text-align: center\"><strong>Helminthosporium in Rye<\/strong><\/p>\n<p>Before Christmas Holidays, we looked at a couple of winter rye fields that were having problems with the lower leaves dying on the plants, and the younger leaves exemplifying numerous necrotic spots.\u00a0 These symptoms were caused by a stressed derived pathogen called Helminthosporium.\u00a0 This disease is the causal agent of the leaf spot\/blotch that occurs on forages such as rye.\u00a0 \u00a0Since Helminthosporium is a stress related pathogen, anaerobic conditions such as standing water, lack of oxygen, or fertility issues are the primary cause of this disease.\u00a0 Therefore, it is very important to practice good management practices such as:<\/p>\n<ul>\n<li>Checking soil fertility to maintain the adequate levels of fertility needed<\/li>\n<li>Checking pH because nutrient uptake is influenced by pH<\/li>\n<li>Alleviating thatch build up and compaction.<\/li>\n<\/ul>\n<p>Maintaining these practices will help control stressed derived pathogens like Helminthosporium.<\/p>\n<p>As shown in the by the pictures below, in some areas of the field, the rye had almost completely died.\u00a0 The lesions present on the leaves were small or large, ranged in shape from oval to elongated, and were yellowish-tan to reddish-brown in color. \u00a0When the intensity of the disease is high like in some areas of the fields we visited, the lesions on the leaves will merge forming large irregular areas of diseased tissue.\u00a0 Helminthosporium will not only cause leaf symptoms, but also brown decay of the lower stems.\u00a0\u00a0 This disease can be a problem when the infection is severe because many leaves will die causing reduced yields and grain quality.<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/site.extension.uga.edu\/colquittag\/files\/2016\/01\/Helminthosporium-in-Rye-2.jpg\" rel=\"attachment wp-att-1149\"><img
