- The study of plant diseases is known as plant pathology. Infectious diseases are caused by living organisms called pathogens. Noninfectious diseases caused by environmental stress and damage by weather and other environmental factors also will be covered.ndirectly, environmental factors that cause a plant to be stressed may result in the plant's gradual decline. Decline results in the plant being more susceptible to disease organisms. Because of this, diagnosing plant diseases can be tricky.

- Fungal diseases are often caused by fungi that are common in the environment. Fungi live outdoors in soil and on plants and trees as well as on many indoor surfaces and on human skin.Most fungi are not dangerous, but some types can be harmful to health.ucormycosis – A rare infection caused by different fungi that belong to a group of fungi called Mucoromycotina. These fungi typically live in soil and in association with decaying organic matter, such as leaves, compost piles, or rotten wood. 1  Symptoms. 2  Risk and Prevention. 3  Diagnosis and Testing.

- A plant disease is usually defined as abnormal growth and/or dysfunction of a plant. Diseases are the result of some disturbance in the normal life process of the plant. Diseases may be the result of living and/or non-living causes. Biotic diseases are caused by living organisms such as fungi, bacteria, and viruses.

- Other fungi provide numerous drugs (such as penicillin and other antibiotics), foods like mushrooms, truffles and morels, and the bubbles in bread, champagne, and beer. Fungi also cause a number of plant and animal diseases: in humans, ringworm, athlete's foot, and several more serious diseases are caused by fungi.Because fungi are more chemically and genetically similar to animals than other organisms, this makes fungal diseases very difficult to treat.lant diseases caused by fungi include rusts, smuts, and leaf, root, and stem rots, and may cause severe damage to crops. However, a number of fungi, in particular the yeasts, are important model organisms for studying problems in genetics and molecular biology.

- Most plant diseases cause a loss of yield or damage the aesthetic qualities of the infected plant. Certain diseases of trees, however, weaken their structure and create a hazardous situation where property damage or serious bodily injury could result from falling limbs or the toppling of the entire tree.

Plant Diseases Disease fungi take their energy from the plants on which they live. They are responsible for a great deal of damage and are characterized by wilting, scabs, moldy coatings, rusts, blotches and rotted tissue.

Signs and symptoms of plant disease: Is it fungal, viral or bacterial? You are not actually seeing the disease pathogen, but rather a symptom that is being caused by the pathogen. Here are a few examples of common signs and symptoms of fungal, bacterial and viral plant diseases: Fungal disease signs: 1  Leaf rust (common leaf rust in corn).2  Stem rust (wheat stem rust).3  Sclerotinia (white mold).ou are not actually seeing the disease pathogen, but rather a symptom that is being caused by the pathogen. Here are a few examples of common signs and symptoms of fungal, bacterial and viral plant diseases: Fungal disease signs: 1  Leaf rust (common leaf rust in corn).

- Fruit Rots. Fruit rot results from infection by fungi, bacteria, or abiotic disorders (see abiotic diseases for information on non-parasitic fruit disorders). Some viruses also cause fruit damage, however, the rot that results from these infections is usually caused by secondary fungi or bacteria.hree common soil fungi cause severe wilt and root rot diseases in chile. These fungi can cause similar symptoms, most notably severe wilting and plant death, and at times may be confused with one another.

Signs and symptoms of plant disease: Is it fungal, viral or bacterial? Most plant diseases – around 85 percent – are caused by fungal or fungal-like organisms. However, other serious diseases of food and feed crops are caused by viral and bacterial organisms. Certain nematodes also cause plant disease.

- Fungal Diseases. There are two major contagious skin diseases caused by fungi, one is more frequent in children, and the other in teens and adults. They are: 1  Ringworm-This is caused by a fungus called dermatophyte. 2  It can be passed from person to person, or from animals to people.ontagious Skin Diseases can have three major causes. If you'd like to explore those caused by viruses, visit the skin disease photos page, where we show pictures of these diseases as well as give you basic information about them. The next major cause of these diseases is bacterial, and a third major cause is fungal.

- Pathogens and susceptible plants. The majority of leaf spot diseases are caused by fungi, but a few unique diseases discussed below are caused by bacteria or other pathogens. Many of these pathogens are somewhat host specific and will only cause disease on trees of the same species or genus.

Peace Lily Turning Yellow The two primary diseases of peace lily are caused by the Cylindrocladium spathyphylli and Phytophthora parasitica fungi. Both these fungal pathogens live in soil where they attack peace lily roots and cause them to rot. Above-ground symptoms include leaves that wilt and turn yellow, starting at the base of plants.Once plants are infected, there is no practical cure and they should be discarded.oth these fungal pathogens live in soil where they attack peace lily roots and cause them to rot. Above-ground symptoms include leaves that wilt and turn yellow, starting at the base of plants.

- Diseases. Anthracnose: This disease is caused by the fungi Colletrotrichum and Gloeosporium. The leaf tips turn yellow, then tan, then dark brown. The browning may extend completely around the leaf. The leaves eventually die. Wounding enhances penetration by these fungi.

diseases of plants Most plant diseases are caused by fungi, bacteria, and viruses. Although the term disease is usually used only for the destruction of live plants, the action of dry rot and the rotting of harvested crops in storage or transport is similar to the rots of growing plants; both are caused by bacteria and fungi.ost mosaic diseases and many other types of chlorosis are caused by viruses (see virus). Plant diseases are more often classified by their symptoms than by the agent of disease, because the discovery of microscopic agents such as bacteria dates only from the 19th cent. (see Louis Pasteur).

Fungus Plant Diseases Fungi are parasites that do significant damage to plants and particularly cultivated plants. Roughly 80 percent of all plant diseases come from fungi. Fungal spores are spread by agents such as water and wind to other plants. They develop in humid conditions and are often microscopic, growing on both living and dead plant tissues. Fungal diseases can be seen at any time of year, but mostly occur during fruiting.

Plant pathology Most bacteria that are associated with plants are actually saprotrophic, and do no harm to the plant itself. However, a small number, around 100 known species, are able to cause disease. Bacterial diseases are much more prevalent in sub-tropical and tropical regions of the world.rganisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants.
