Cercospora theae is a fungal plant pathogen. It is the pathogen that causes bird's eye spot disease in tea plants. [1]
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. Symptoms can overlap across causal agents, however differing signs and symptoms of certain pathogens can lead to the diagnosis of the type of leaf spot disease. Prolonged wet and humid conditions promote leaf spot disease and most pathogens are spread by wind, splashing rain or irrigation that carry the disease to other leaves.
Pseudocercosporella capsellae is a plant pathogen infecting crucifers. P. capsellae is the causal pathogen of white leaf spot disease, which is an economically significant disease in global agriculture. P. capsellae has a significant affect on crop yields on agricultural products, such as canola seed and rapeseed. Researchers are working hard to find effective methods of controlling this plant pathogen, using cultural control, genetic resistance, and chemical control practices. Due to its rapidly changing genome, P. capsellae is a rapidly emerging plant pathogen that is beginning to spread globally and affect farmers around the world.

Pseudocercospora is a genus of ascomycete fungi. An anamorphic version of the genus Mycosphaerella, Pseudocercospora species are plant pathogens, including the causal agent of the so-called South American leaf blight of the rubber tree. The widely distributed genus is concentrated predominantly in tropical regions. Pseudocercospora was circumscribed by Italian-Argentinian botanist Carlos Luigi Spegazzini in 1910.
In biology, a pathogen, in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ.
C. theae can refer to a few different species (below). The specific epithet theae refers to tea, and many of the below are pathogens of the tea plant.
Pseudopestalotiopsis is a genus of plant pathogens in the family Sporocadaceae.
