Depending on the species, it can also spread through contact and via spores present in the environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The main entry routes can be related to the <strong>root system, plant wounds, and contaminated cultivation material<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fusarium_and_the_roots\"><\/span>Fusarium and the roots<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fungi that affect the roots can penetrate through the <strong>root system<\/strong>, especially when there are damaged or deteriorating tissues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Wounds can also facilitate the entry of the pathogen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fusarium_and_the_vascular_system\"><\/span>Fusarium and the vascular system<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In certain fusarioses, the fungus can penetrate the plant and reach the <strong>xylem<\/strong>, from where it can spread through the vascular system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This type of infection can cause significant problems in the transport of water and nutrients.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fusarium_and_stem_damage\"><\/span>Fusarium and stem damage<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Species that affect the stem can take advantage of <strong>wounds caused during pruning, staking, or plant handling<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, it is important to always work with clean tools and avoid causing unnecessary damage to plant tissues.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fusariosis_symptoms_of_Fusarium\"><\/span>Fusariosis: symptoms of Fusarium<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Fusarium can manifest in different ways, so it is important to <strong>periodically check the plants<\/strong> and pay attention to the foliage as well as the stem and root system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Among the symptoms that may appear, we find:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Yellowing of the lower leaves.<\/li>\n\n\n\n<li>Premature wilting.<\/li>\n\n\n\n<li>Discolored leaves with a tendency to curl upwards.<\/li>\n\n\n\n<li>Branches that appear wilted individually.<\/li>\n\n\n\n<li>General decay of the plant.<\/li>\n\n\n\n<li>Brown or necrotic areas on the roots.<\/li>\n\n\n\n<li>Coloration changes in certain areas of the stem.<\/li>\n\n\n\n<li>Calluses or swellings on the trunk.<\/li>\n\n\n\n<li>Excessively wet or foul-smelling substrate.<\/li>\n\n\n\n<li>Plants that show difficulty absorbing water.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_differentiate_Fusarium_from_other_problems\"><\/span>How to differentiate Fusarium from other problems?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fusarium symptoms can be confused with those caused by <strong>excess moisture, root problems, environmental stress, or nutritional deficiencies<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the presence of one of these symptoms alone does not confirm a Fusarium infection.

Therefore, it is advisable to observe the cultivation area beforehand and remove <strong>weeds and decaying plant remains<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is also important to avoid areas with excess moisture or poor drainage.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Soil solarization<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Solarization<\/strong> is a technique used to raise the soil temperature by placing a transparent plastic over its surface for a certain period.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It can be part of a preventive soil management strategy, always taking into account environmental conditions and the correct application of the technique.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"

class=\"wp-block-paragraph\">The substrate plays a fundamental role in the healthy development of the roots.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An <strong>aerated medium with good drainage and the ability to evacuate excess water<\/strong> helps to avoid waterlogging conditions that can favor different root problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Among the materials that can be used to improve the structure and aeration of the substrate are <strong>perlite, expanded clay, and coconut fiber<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span

the environment are other factors we must monitor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A substrate that remains <strong>constantly soaked<\/strong>, combined with insufficient ventilation, can create unfavorable conditions for the roots.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, it is advisable to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Avoid overwatering.<\/li>\n\n\n\n<li>Use containers with adequate drainage.<\/li>\n\n\n\n<li>Avoid keeping the substrate constantly saturated.<\/li>\n\n\n\n<li>Maintain adequate

class=\"wp-block-paragraph\">During this phase, it is advisable to use <strong>clean materials<\/strong>, quality water, and properly sanitized containers.<\/p>\n\n\n\n<p

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cuttings require special attention because the wounds produced during cutting can become vulnerable

class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To reduce risks:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use clean and disinfected

clean.<\/li>\n\n\n\n<li>Avoid handling healthy plants and potentially contaminated material simultaneously.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When receiving cuttings from third parties, it may be advisable to keep them <strong>separated from the rest of the plants during an observation period<\/strong>, especially when their origin or the conditions in which they were propagated are unknown.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Nutrition_and_root_system_health\"><\/span>Nutrition and root system health<span
