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 ...
As the inoculum is spread, the younger sugarcane buds just coming out of the soil will be the most susceptible. Water is necessary for the spores to germinate, and irrigation methods have been shown to be a factor in spreading the disease. Therefore, special precautions need to be taken during irrigation to prevent spreading the smut. [5]
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.
Rhododendron ponticum showing classic symptoms of Phytophthora kernoviae in the UK. 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 are capable of causing enormous economic losses on crops worldwide, as well as environmental damage in natural ...
Mucor mucedo, commonly known as the common pinmould, [1] is a fungal plant pathogen and member of the phylum Mucoromycota and the genus Mucor. [2] Commonly found on soil, dung, water, plants and moist foods, Mucor mucedo is a saprotrophic fungus found world-wide with 85 known strains.
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 ...
The spores are wind-dispersed and they are often extremely abundant in outdoor air. Indoors Cladosporium species may grow on surfaces when moisture is present. Cladosporium fulvum , cause of tomato leaf mould, has been an important genetic model, in that the genetics of host resistance are understood. [ 4 ]
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 ...
