Coffee Rust Fungus of the Coffea Genus

Introduction Coffee beans are one of the most widely used products in the world and almost all continents are involved. In rust disease of coffee: epidemiology, resistance and management Ajimada Kusharrappa insists that "oil coffee is the most important product in international trade" (Kusharrappa, Eskes 1989). Economic stability plays an important role. Coffee rust is a coffee tree disease proved to be able to remove farmers' crops in a short time.

Coffee is a brewed beverage made from coffee bean roasting, coffee beans are a berry seed of a particular coffee variety. Coffee belongs to reunion in tropical Africa (especially from Ethiopia and Sudan) and Madagascar, Comoros, Mauritius and the Indian Ocean. Coffee plants are currently grown mainly in the equatorial regions of the Americas, Southeast Asia, India and Africa in more than 70 countries. The two most commonly cultivated are C. arabica and C. robusta. After ripening, pick out coffee berries, process and dry. Dried coffee seeds (called "beans") are baked to varying degrees according to the desired flavor. Grind the roasted beans, brew with boiling water, and make drinks called coffee.

Several shrubs of the coffee genus produce fruits that extract coffee. The two main types cultivated commercially are Coffea canephora (mainly in the form of 'robusta') and C. arabica. Arabica is the most highly regarded species, growing in the highlands of the southwest of Ethiopia and the Boma Plateau in the southeastern part of Sudan, and perhaps in the Massabate mountain range in northern Kenya. C. canephora is native to sub-Saharan Africa in the western and central parts ranging from Guinea to Uganda and South Sudan. The less popular species is C. liberica, C. Stenofila, C.I. Maurishana and C. rasemosa

There are about 25 major coffee varieties in the world, but only three of them are cultivated for commercial use. The main ones are Coffea Arabica, Coffea canephora, Liberica (Coffea arnoldiana De Wild). However, due to grafting among coffee cultivars there are already varieties of coffee varieties (also known as breeds) already derived from Arabic coffee or Robusta coffee. Arabian coffee (about 60 to 70% of the coffee market). Coffea Arabica is from the mountains of Yemen and Ethiopia and is planted in farms all over the world. This makes mechanical harvesting difficult. Because they usually grow at high altitude of steep slopes. Therefore, farmers often have to do manual picking. However, because beans are too low or too ripe to eliminate it more effectively, higher quality assurance can be obtained by manually picking these beans. This will produce higher quality coffee beans for baking
