What Cercospora produces?
A remarkably effective plant-pathogenic fungus, Cercospora, produces a pigment that efficiently sensitizes singlet molecular oxygen. Peroxidation of the plant cell membrane causes the cells of the infected plants to burst, giving nutrients to the fungus.
Where does Cercospora come from?

Cercospora Blight Identification/Symptoms: Primarily a leaf-spotting disease, Cercospora blight’s first symptoms arrive as small leaf spots.
Is Cercospora poisonous?
Cercosporin is unique among fungal toxins in that it is activated by light and becomes toxic to plants by generating activated species of oxygen, particularly single oxygen.
Does Cercospora spread?
In carrots, Cercospora blight starts with small, irregular, purple-green to purple-black leaf spots. In celery, early blight symptoms begin as small, circular yellow or brown leaf spots. When conditions support this disease, it spreads rapidly across leaves and through crops.
How do you identify Cercospora?
The spots were initially uniformly brown to reddish brown, turning pale brown with a purplish margin and showing grayish patches on the lesion due to heavy fructification. The causative agent of the leaf spot disease was identified as Cercospora malayensis.
How is Cercospora treated?
Fungicides are available to manage Cercospora leaf spot. Many of the conventional products used to prevent black spot of roses will also protect against Cercospora leaf spot. These fungicides contain the active ingredient chlorothalonil (OrthoMax Garden Disease Control) and myclobutanil (Immunox).
What kind of disease does Cercospora beticola cause?
Cercospora beticola is a fungal plant pathogen which typically infects plants of the genus Beta, within the family of Chenopodiaceae. It is the cause of Cercospora leaf spot disease in sugar beets, spinach and swiss chard. Of these hosts, Cercospora leaf spot is the most economically impactful in sugar beets ( Beta vulgaris).
How is the taxonomy of Cercospora based on?
The species concept and taxonomy of Cercospora are based upon morphological criteria, primarily the dimensions and characteristics of the conidia (length, width, base, and tip) and conidiophores (length, diameter, geniculation, and fasciculation) (Chupp, 1954).
What does CBT do to a Cercospora plant?
C. beticola is a necrotrophic fungus that uses phytotoxins specifically Cercospora beticola toxin (CBT) to kill infected plants. CBT causes the leaf spot symptom and prevents root formation. Yield losses from Cercospora leaf spot are around 20 percent.
