roses.<\/p>\n\n\n\n<p>They appear as circular black spots on the upper and lower sides of rose leaves.<\/p>\n\n\n\n<p>As the disease progresses, the spots may merge, causing the leaves to yellow and eventually drop.<\/p>\n\n\n\n<p>Severe leaf stripping can occur, leaving the plant weak and vulnerable to other diseases and environmental stresses.<\/p>\n\n\n\n<p>Black spot can also infect stems and trunks, causing purple-black spots.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"565\" height=\"437\"

of black spot disease in roses<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Black spot is caused by the fungus Diplocarpon rosae, which can live on fallen leaves and plant debris during the winter.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%D8%B8%D8%B1%D9%88%D9%81_%D9%85%D8%B1%D8%B6_%D8%A7%D9%84%D8%A8%D9%82%D8%B9_%D8%A7%D9%84%D8%B3%D9%88%D8%AF%D8%A7%D8%A1_%D9%81%D9%8A_%D8%A7%D9%84%D9%88%D8%B1%D8%AF_%D8%A7%D9%84%D8%AC%D9%88%D8%B1%D9%8A\"><\/span>Conditions of black spot disease in roses<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Black spot fungus grows in warm, humid conditions with temperatures between 18\u00b0C and 24\u00b0C (65\u00b0F and 75\u00b0F).<\/p>\n\n\n\n<p>The fungus requires long periods of keeping the leaf moist (at least 10-12 hours) for spore germination and infection.<\/p>\n\n\n\n<p>The disease can spread rapidly via water splashes, wind, and infected plant material.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%D8%AF%D9%88%D8%B1%D8%A9_%D9%85%D8%B1%D8%B6_%D8%A7%D9%84%D8%A8%D9%82%D8%B9_%D8%A7%D9%84%D8%B3%D9%88%D8%AF%D8%A7%D8%A1_%D9%81%D9%8A_%D8%A7%D9%84%D9%88%D8%B1%D8%AF_%D8%A7%D9%84%D8%AC%D9%88%D8%B1%D9%8A\"><\/span>Black spot disease cycle in roses<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The black spot fungus overwinters as dormant threads or fruiting structures (pseudocotyls) on fallen leaves and plant debris.<\/p>\n\n\n\n<p>In the spring, when temperatures and humidity levels are favourable, the fungus produces spores (spore-forming spores) that can start new infections on young, susceptible leaves.<\/p>\n\n\n\n<p>The fungus then produces additional spores (achenes) that can spread the disease throughout the growing season.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span

spot disease losses in roses<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Severe black spot infestations can result in significant leaf stripping, reduced plant vigor, and reduced flower production.<\/p>\n\n\n\n<p>In extreme cases, the disease can weaken the plant to the point that it becomes vulnerable to other pathogens or environmental stresses, leading to the plant&#039;s death.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"
