Pyrenophora tritici-repentis. (Died.) Drechsler, (1923) Pyrenophora tritici-repentis (teleomorph) and Drechslera tritici-repentis (anamorph) is a necrotrophic plant pathogen of fungal origin, phylum Ascomycota. [1] The pathogen causes a disease originally named yellow spot but now commonly called tan spot, yellow leaf spot, yellow leaf blotch ...
Alternaria alternata is a fungus causing leaf spots, rots, and blights on many plant parts, and other diseases. It is an opportunistic [citation needed] pathogen on over 380 host species of plant. It can also cause upper respiratory tract infections [ 1 ] and asthma in humans with compromised immunity. [citation needed]
Tremella mesenterica (common names include yellow brain, golden jelly fungus, yellow trembler, and witches' butter[ 2 ]) is a common jelly fungus in the family Tremellaceae of the Agaricomycotina. The gelatinous, orange-yellow fruit body of the fungus, which can grow up to 7.5 cm (3 in) diameter, has a convoluted or lobed surface that is greasy ...
The disease starts out as yellowing and drooping on one side of the plant. Leaf wilting, plant stunting, browning of the vascular system, leaf death and lack of fruit production also occur. [8] F. oxysporum f. sp. melonis attacks muskmelon and cantaloupe. It causes damping-off in seedlings and causes chlorosis, stunting and wilting in old plants.
A leaf spot is a limited, discoloured, diseased area of a leaf that is caused by fungal, bacterial or viral plant diseases, or by injuries from nematodes, insects, environmental factors, toxicity or herbicides. These discoloured spots or lesions often have a centre of necrosis (cell death). [ 1 ] Symptoms can overlap across causal agents ...
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. It affects young seedlings, mature plants, and fruit in the field or in storage.
Alternaria leaf spot or Alternaria leaf blight are a group of fungal diseases in plants, that have a variety of hosts. [1][2][3] The diseases infects common garden plants, such as cabbage, and are caused by several closely related species of fungi. [4] Some of these fungal species target specific plants, while others have been known to target ...
