Abstract

The coffee twig borer (Xylosandrus compactus Eichhoff) is an economically important pest of Robusta coffee in Uganda. In this study, a formicid ant, Plagiolepis sp., found in X. compactus galleries at the National Coffee Research Institute in 2014, was evaluated for potential to provide biological...

Abstract

In March and June 2013, maize plants showing signs of maize lethal necrosis (MLN) disease symptoms were observed in the Northern Province of Rwanda. The diseased samples were brought to the laboratory and analysed. The causal pathogens were identified as Maize chlorotic mottle virus (MCMV) and...

Abstract

Coffee Leaf Rust and Coffee Berry Disease are the most devastating diseases of Arabica coffee in Africa. The importance of coffee in economies of many African countries like Uganda, presents urgent need for cost-effective disease control strategies. In this study, 192 coffee farms were surveyed and ...

Abstract

Varietal resistance to existing pathogen populations is important in the management of disease epidemics in crop farming systems. Coffee Leaf Rust (CLR) caused by Hemileia vastatrix (Berk. and Broome) is a serious impediment to Arabica coffee (Coffea arabica Linneaus) production in Uganda. The...

Abstract

Understanding the genetic diversity existing in a germplasm collection is important to identify parental combinations with distinct gene sets that can be used in crossing to obtain superior hybrids. This study was carried out to evaluate the genetic diversity in the Rwandan coffee germplasm using...

Abstract

The diagnosis of novel unidentified viral plant diseases can be problematic, as the conventional methods such as real-time PCR or ELISA may be too specific to a particular species or even strain of a virus, whilst alternatives such as electron microscopy (EM) or sap inoculation of indicator species ...

Abstract

Coffee Leaf Rust (CLR) caused by Hemileia vastatrix Berk. and Br. has a worldwide distribution and causes enormous yield losses. A survey was conducted in Rwanda to evaluate incidence and severity of CLR and other coffee pests and diseases and to determine how the crop management contributes to CLR ...
