Plant Diseases 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. This page is designed to help identify some of the more common plant diseases and provides earth-friendly solutions (see organic fungicides) for combatting them.

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.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). 2  Stem rust (wheat stem rust). 3  Sclerotinia (white mold).

- Fungi cause many kinds of diseases in plants and animals. Diseases in humans caused by fungus infection range from skin disorders to serious illness. Fungal diseases like blastomycosis, coccidioidomycosis, and candidiasis in humans often attack the lungs.Thrush, a fungal disease of the throat, is found mainly in infants. Histoplasmosis-is caused by the fungus Histoplasma capsulatum, it is found in soil fertilized by bat droppings. 2  It is most prevalent in the Ohio River and Mississippi Valley. 3  This illness is also known as Cave disease and Darling's disease. 4  The illness presents with flu-like symptoms and can resemble tuberculosis.

Plant Fungus Types Cosmetic Fungus. Cosmetic fungal diseases generally infect the foliage and fruit of the plant. These fungal diseases infect the plant from the surface rather than through the root system. Infected foliage of the plant will display varying symptoms that depend on the type of infecting fungus.he fungus may appear on the foliage, near the base of the plant or even on the fruit and flowers of the plant. Though some fungal outbreaks can be a simple cosmetic hassle, other fungal outbreaks can cause permanent injury and even death of the plant.

Plant disease Plant disease. Plant disease, an impairment of the normal state of a plant that interrupts or modifies its vital functions. All species of plants, wild and cultivated alike, are subject to disease. Although each species is susceptible to characteristic diseases, these are, in each case, relatively few in number. The occurrence and prevalence of plant diseases vary from season to season, depending on the presence of the pathogen, environmental conditions, and the crops and varieties grown.

Grow Healthy Food By Identifying + Treating These Common Plant Diseases Rots are diseases that decay roots, stems, wood, flowers, and fruit. Some diseases cause leaves to rot, but those symptoms tend to be described as leaf spots and blights. Rots can be soft and squishy or hard and dry.lants wilt when they don't get enough water. When fungi or bacteria attack or clog a plant's water-conducting system, they can cause permanent wilting, often followed by the death of all or part of the plant.

Rust Rust, disease of thousands of economically important plants, as well as weeds, caused by more than 4,000 species of fungi. 1  During their life cycle rust fungi parasitize either one species of plant (autoecious, or monoecious, rust) or two distinct species (heteroecious rust). One heteroecious rust with five spore forms during its life cycle is black stem rust (Puccinia graminis) of wheat and other cereals and grasses.
