Coffee Berry Disease and Coffee Leaf Rust in Kenya
Outlook on Agriculture, 1964Recent research into the biology of the fungi causing coffee berry disease and coffee leaf rust has resulted in a better understanding of the spread of these diseases under East African conditions and of the steps necessary for their control. In both cases timely checking of the organisms in advance of their phases of rapid proliferation and dispersal

Phytochemistry, 2006
In plants, PPO has been related to defense mechanism against pathogens and insects and this role was investigated in coffee trees regarding resistance against a leaf miner and coffee leaf rust disease. PPO activity was evaluated in different genotypes and in relation to methyl-jasmonate (Meja) treatment and mechanical damage.

Silicon and Triadimenol for the Management of Coffee Leaf Rust
Journal of Phytopathology, 2013AbstractThis study documents an experiment that was undertaken in the 2006/2007, 2007/2008 and 2008/2009 growing seasons on Coffea arabica cv. ‘Catuaí Vermelho IAC 144’ that sought to evaluate the effects of various calcium silicate rates combined with the fungicide triadimenol on the incidence of coffee leaf rust.

Sensitization to the fungus Hemileia vastatrix (coffee leaf rust)
Allergy, 2001Background: The aim of the present study was to determine the existence of sensitization to the fungus Hemileia vastatrix (coffee leaf rust) in a sample of the Brazilian population. This fungus attacks coffee plantations, and in some regions of Brazil the concentration of its spores in the air can be very high.

Ricoseius loxocheles, a phytoseiid mite that feeds on coffee leaf rust
Experimental and Applied Acarology, 2014One of the most important diseases of coffee plants is the coffee leaf rust fungus Hemileia vastatrix Berkeley and Broome (Uredinales). It can cause 30 % yield loss in some varieties of Coffea arabica (L.). Besides fungus, the coffee plants are attacked by phytophagous mites.

Fungal Biology
Here, we report on a Cordyceps species entering into a multi-trophic, multi-kingdom association. Cordyceps cateniannulata, isolated from the stem of wild Coffea arabica in Ethiopia, is shown to function as an endophyte, a mycoparasite and an entomopathogen.

Control of coffee leaf rust in Kenya Colony
Transactions of the British Mycological Society, 1962Results of twenty-seven trials sited at altitudes between 5000 and 6200 ft. in districts both east and west of the Rift Valley were all similar. The conclusions which can be drawn are: (1) maximum control of Hemileia vastatrix is obtained by treatments applied before commencement and during the early period of the rains; (2) timing of treatments is ...

Incomplete Resistance to Coffee Leaf Rust
1983Incomplete resistance to Hemileia vastatrix Berk. et Br. has been studied in Brazil under field, greenhouse, nursery and laboratory conditions. The following coffee populations were studied: breeding lines and cultivars of C. arabica, and c. canephora cultivars Kouillou, Icatu andCatimor.

Effect of shade on the severity of coffee leaf rust [PDF]
, 2015 Coffee Leaf Rust (CLR) caused by the fungi Hemileia vastatrix Berkeley and Broome has been causing leaf losses of up to 70% in Arabica coffee. The aim of this study was to determine the effect of shade on the progression and severity of Coffee Leaf Rust in Murang'a County in Kenya. Thirty eight (38) small scale coffee farms were randomly selected.
