Pseudocercospora subsessilis is a fungal plant pathogen infecting chinaberry tree ( Melia azedarach ). It is widespread in tropical and subtropical areas on host species of the genera Azadirachta and Swietenia . [1]

Contents

It was originally published as Cercospora subsessilis in 1913 and found on the leaves of the chinaberry tree in Tamil Nadu, India. [2] Before the species was transferred to the Pseudocercospora genus. [3]

The fungal leaf spots can amass to blight the entire leaf and were also capable of rapidly defoliating whole trees in late September. [4]

The disease has been reported in several other Asian countries as well as in Cuba and the United States. [5]

Distribution

It is found in Burma, Cuba, Hong Kong, India, Jamaica, Japan, China, Nepal, Palestine, Philippines, San Domingo, Sierra Leon, Sri Lanka, Sudan, Taiwan, U.S.A. and Venezuela. [6] It was later found in Korea, on ornamental planted chinaberry trees. [4]

<i>Azadirachta</i> Genus of flowering plants

Azadirachta is a genus of two species of trees in the mahogany family Meliaceae. Numerous species have been proposed for the genus but only two are currently recognized, Azadirachta excelsa and the economically important tree Azadirachta indica, the neem tree, from which neem oil is extracted. Both species are native to the Indomalaysian region, and A. indica is also widely cultivated and naturalized outside its native range.

<i>Cercospora</i> Genus of fungi

Cercospora is a genus of ascomycete fungi. Most species have no known sexual stage, and when the sexual stage is identified, it is in the genus Mycosphaerella. Most species of this genus cause plant diseases, and form leaf spots. It is a relatively well-studied genus of fungi, but there are countless species not yet described, and there is still much to learn about the best-known members of the genus.

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.
