Then, suddenly, you notice black spots on the leaves. Perhaps black spots appear on the leaves all over a whole section of your plants. This is what is called black spot fungus.<\/span><\/p>\n<h2><b>What are black spots on plant leaves?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Black spot disease is a common fungal disease that is stressful for farmers, caused by the black spot fungus, which affects the shape of the plant, making it look bad and causing the leaves to fall prematurely, thereby weakening the plant.<\/span><\/p>\n<h2><b>How is the disease discovered or diagnosed?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">There are some symptoms that you can look for that are known to be associated with black spot disease on various plant leaves,<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><span style=\"font-weight: 400;\">For example, in flowers:<\/span><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">You can notice the deterioration of the health of the flowers, the appearance of some black spots on the edges of the leaves, yellowing of some leaves, and their fall. You may also find purple areas of plant tissue in the stem.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><span style=\"font-weight: 400;\">While in trees:<\/span><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The symptoms to look for are black spots or dead tissue of leaves, broken branches, and curled leaves. You may find some deformed branches in trees that are shedding their leaves.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><span style=\"font-weight: 400;\">Vegetables:<\/span><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Start searching for tomatoes, as they are most susceptible to black spots. Look for early blight problems, which are caused by a fungal disease and result in the appearance of black spots. You can also search the ground for yellow leaves that have fallen prematurely. Touch the spots to see if they are wet; this is a sign of plant infection.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><span style=\"font-weight: 400;\">Fruit Trees:<\/span><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Search for bacterial infections caused by some pathogenic bacteria, where you will notice small, irregular black spots clustering near the ends of the leaves and along the veins. These spots may also appear speckled. You may also find dead spots on some areas of the leaf that have fallen from the plant, leaving holes.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><span style=\"font-weight: 400;\">Ornamental plants:<\/span><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">A gray mold disease can appear on ornamental plants.
