The owner was named Mr. Kent, and hence the name, Kent's coffea. This plant has been sent to India, East Africa and many other areas where Hemileia Vastatrix is a problem. It was found that Kent's coffea is resistant all but two of the varieties of Hemilea Vastatrix. This is a fungus. The process which kills the plant is faster than leaf rust.
Defoliation can be swift and sever.
The particular disease is prevalent in the Americas. There are regions in Mexico, Guatemala, Costa rica, Colombia, and Brazil which whole plantations have been wiped out because of this disease. The spores will live indefinitely in the ground and make the area permanently troubled. This disease will kill other crops as cacao and citrus. In general, it affects only the arabica variety and not the robusta variety.
