When pepper plants are under stress, their leaves have a tendency to become very pale and dry and black spots on pepper leaves, which is a condition called black spot.

The problem that pepper plants face is that they have lots of leaves. These leaves shade the plants and prevent light from reaching the fruit, which means it doesn’t grow properly. Pepper growers know that they can easily remove the old leaves, but there’s a problem: the new leaves have a tendency to get covered up, and in the process, they often lose their natural color.

Here are some reasons why peeper leaves black spot and what you can do to fix the problem.

Reasons Behind Tiny Black Spots On Pepper Leaves

The spots on pepper leaves are not holes caused by a virus. They are tiny black spots caused by an insect called the melon fly. The insect feeds on the juice of the pepper fruit and is attracted to its sweet flavor. To survive, the insect needs to eat a lot. Unfortunately, this feeding also causes the pepper leaves to darken. The insect doesn’t need to eat very often. It simply sits on the leaves and waits for them to wither and die. Here are the other common reasons behind the  pepper leaves black spot  and some tips to solve it:

  1. Black Sooty Mold

“Black Sooty Mold” on pepper leaves are caused by two different molds, Botrytis cinerea and Phytophthora capsici, and are usually found together on the leaves and stems of pepper plants. B. cinerea tends to affect peppers in the hot weather while P. capsici prefers to grow during cooler weather. These molds appear on all parts of the plant but especially on the stems and leaves.

Black Sooty Mold is usually found on pepper leaves and fruits, but can also cause leaf spots and blights on peppers. The best way to control this fungus is to remove all leaves and fruit from the plant and treat the plant with Bordeaux Mixture, a sulfur-based fungicide.

  1. Fusarium

Fusarium, a fungus that causes Fusarium wilt, a disease that attacks pepper plants, is one of the major diseases of pepper. Since peppers are usually eaten raw or minimally processed, the disease can cause serious damage to crops. Fusarium can kill up to 90% of pepper plants. Fusarium is a common disease affecting peppers, tomatoes, cucumbers, pumpkins, eggplant, tobacco, and a wide variety of other crops. Fusarium infections can also affect many types of soil including soil and water. It makes black spots on pepper leaves

  1. Bacterial Leaf Spot

Bacterial Leaf Spot (BLS) is one such disease. It infects both bell peppers and chiles. In fact, the only way to tell whether a pepper has been infected is by examining the leaves. Unfortunately, many growers are not looking for this disease or its symptoms because they don’t understand the importance of knowing what they are seeing.

  1. Tobacco Mosaic Virus

The Tobacco mosaic virus causes severe diseases in tobacco, peppers, and tomatoes. Researchers have found that the virus survives in water and soil and is capable of infecting new plant species, such as kiwifruit and cucumber. Tomato greenhouses, which were planted with transgenic tobacco plants, were infected. This is the first report of infection of non-tobacco crops by a virus engineered for use in tobacco. It makes black spots on pepper leaves.

The mosaic virus, which causes mosaic disease, is a plant pathogen of many crops. Symptoms include chlorotic mottling, spots of necrotic tissue, distortion of plant growth, and leaf drop. The virus can cause leaf yellowing, stem galls, and premature fruit abscission. Transmission is usually through wind-dispersed seed but can also be spread through infected vegetative material.

The acid helps dissolve the fungus, and it can be reapplied as often as necessary. Do not use other fungicides to control the disease of pepper leaves black spot, as they may damage the plant.
