Ulocladium is a genus of fungi.Species of this genus contain both plant pathogens and food spoilage agents. Other species contain enzymes that are biological control agents. . Some members of the genus can invade homes and are a sign of moisture because the mold requires water to t
Mold propagates via spores, which are always present in the environment. Mold spores can be transferred to an object by mechanical instruments or air circulation. When spores attach to another organism, and the environment is favorable, they begin to germinate. Mold produce mycelium which growth pattern resembles cobwebs. Mycelium allows the ...
Rain can wash spores into the soil where they infect young tubers, and the spores can also travel long distances on the wind. The early stages of blight are easily missed. Symptoms include the appearance of dark blotches on leaf tips and plant stems. White mold will appear under the leaves in humid conditions and the whole plant may quickly ...
Cladosporium cladosporioides is a common saprotroph occurring as a secondary infection on decaying, or necrotic, parts of plants. [6] This fungus is xerophilic – growing well in low water activity environments (e.g., a W = 0.86–0.88). [14] This species is also psychrophilic, it can grow at temperatures between −10 and −3 °C (14 and 27 ...
Sooty mold is commonly seen on the leaves of ornamental plants such as azaleas, gardenias, camellias, crepe myrtles, Mangifera and laurels. Karuka is affected by sooty mold caused by Meliola juttingii. [6] Plants located under pecan or hickory trees are particularly susceptible to sooty mold, because honeydew-secreting insects often inhabit ...
Phytophthora (from Greek φυτόν (phytón), "plant" and φθορά (phthorá), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species cause economic losses on crops worldwide, as well as environmental damage in natural ecosystems. The cell wall of Phytophthora is made up of cellulose.
White mold affects a wide range of hosts and causes sclerotinia stem rot. It is known to infect 408 plant species. As a nonspecific plant pathogen, [3] diverse host range and ability to infect plants at any stage of growth makes white mold a very serious disease. The fungus can survive on infected tissues, in the soil, and on living plants.
Once the spores of this fungi are spread by air, water, tools and insects, [10] the development of the disease is quick, moving from lower to upper leaves; the controlling must be done as soon as possible. It includes avoiding water on the surface of leaves, handling plants in high humidity, and in the worst case, disinfecting the whole greenhouse.
