the coffee shrub are leaf rust caused by the fungus Hemileia vastatrix, which does considerable damage in the plantations of Arabica, and the coffee berry disease caused by the fungus Colletotrichum coffeanum, which also attacks the Arabica.

Colletotrichum kahawae Waller and Bridge is a highly aggressive and specialized fungal pathogen of coffee, causing the devastating Coffee Berry Disease (CBD), particularly at high altitudes. The disease arises from the unique ability of the pathogen to infect green developing coffee berries. This pathogen is currently confined to the African continent in all countries that grow Arabica coffee. In addition to leaf rust, coffee berry disease (CBD) caused by fungus Colletotrichum kahawae can be a devastating anthracnose causing substantial crop loss in Africa. Several other fungal and bacterial diseases may also affect coffee, causing economic damage to a small extent. Arabica is more susceptible to many diseases than robusta coffee.
CBD is a very severe disease that may destroy up to 80% of the coffee berries if no control measures are taken. The fungus: “First colonies from sporulating lesions densely floccose, grey to dark olivaceous grey, dark greenish in reverse, on 2% malt extract agar at 25 o. The crop has been affected by Coffee Berry Disease (CBD), a fungal infection associated with cold weather, and bacterial blight disease. CBD attacks young green berries, and if uncontrolled can.

Mycological Research Colletotrichum kahawae of Arabica coffee only occurs in Africa, and causes major damage in East Africa and Cameroon. Other names of this disease are "coffee berry anthracnose" and "brown blight of coffee".
The characteristic symptom is a progressive blackening of young, expanding coffee berries. This begins as small water-soaked lesions. Coffee Berry Disease was first reported from Kenya in It has since been recorded from most of the other coffee areas in Africa.
It is not known outside of Africa, although a leaf spot and ripe berry anthracnose caused by related Colletotrichum species has been reported from Guatemala and Brazil. A range of Colletotrichum isolates from coffee, including the coffee berry disease (CBD) pathogen, and representative isolates of C.
gloeosporioides from some other tropical crops are compared. Isolates of the CBD pathogen taken from across its range of distribution in Africa have common morphological, biochemical and pathogenic characteristics.

Coffee: Emerging Health Benefits and Disease Prevention is the first book to present a contemporary and comprehensive summary of the newly-understood bioactive effects of the many compounds in coffee.

The main fungal diseases on coffee are: coffee leaf rust (Fig. 2A) caused by Hemileia vastatrix that leads to defoliation, the coffee berry disease (Fig. 2B) caused by Colletotrichum kahawae that mummifies immature coffee berries, coffee wilt disease (Fig.
2C) caused by Gibberella xylarioides and root rot (Fig. 2D) caused by Armillaria mellea. Colletotrichum kahawae is a fungal plant pathogen that causes coffee berry disease (CBD) on Coffea arabica crops.
The pathogen is an ascomycete that reproduces asexually. The asexual spores (conidia) are stored within acervuli. This disease is considered to be one of the major factors hampering a production in the African continent, which represents the current geographic range of the.
Coffee Diseases and Pests: Coffee Berry Disease. Coffee berry disease was first discovered in Kenya in and is caused by the virulent strain of Colletotrichum coffeanum (Mitchell, 85).The fungus lives in the bark of the coffee tree and produces spores which attack the coffee cherries.

The disease was first recorded in western Kenya in McDonald () reports that coffee berry disease then caused losses of up to 75%, causing the abandonment of coffee in several districts of western Kenya.
A severe epidemic in central Kenya in caused the loss of entire crops and overall losses were in excess of 30% (Griffiths, ). Firman, I.D. and Waller, J.M. () ‘Coffee berry diseases and other Colletotrichum diseases of coffee’, Phytopathological Paper No.

This chapter covers the history and spread, economic impact, symptoms, pathogen characteristics (morphology and growth in culture, variability), epidemiology (infection and sporulation, disease progress) and control (chemical control, resistant cultivars, integrated disease management) of coffee berry disease caused by Colletotrichum kahawae.
Price collapse and oversupply have made coffee a high-profile crop in recent years: never has efficient production and crop protection been more important for reducing costs and increasing quality.
