The weather causes significant losses in the crop, as the severity of infection in some areas ranges from 61-86%, which leads to a decrease in seed yield from 8-16% and a decrease in the oil content of seeds from 8-11%.<\/p>\n\n\n\n<p><strong>Pathogen<\/strong> Casual pathogen<br><strong>The disease is caused by a fungus<\/strong> Puccinia helianthi<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%D8%A7_%D9%84%D8%A3%D8%B9%D8%B1%D8%A7%D8%B6_%D8%A7%D9%84%D9%85%D8%B1%D8%B6%D9%8A%D8%A9_Symptoms_%D9%84%D9%85%D8%B1%D8%B6_%D8%A7%D9%84%D8%B5%D8%AF%D8%A3_%D9%81%D9%8A_%D8%AF%D9%88%D8%A7%D8%B1_%D8%A7%D9%84%D8%B4%D9%85%D8%B3\"><\/span><strong>Pathological symptoms of rust in sunflower<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The infection appears in the form of pustules characteristic of the fungus, with a reddish-brown color on the upper surface of the leaves.
