The deployment of resistant cultivars is the best option to control bacterial leaf blight (BLB) and requires an understanding of the pathogen diversity. BLB caused by Xanthomonas oryzae pv.oryzae is a destructive disease ...

Groundnut Rosette Virus disease (GRD) has long been regarded a major limiting biotic constraint to groundnut production in Sub-Saharan Africa (SSA). The disease is caused by a complex of three viral components that interact ...

Sources of resistance to Aspergillus flavus and accumulation of aflatoxin in maize have been identified elsewhere but no such materials are currently available for use by the maize improvement programme in Uganda. The main ...

Cowpea (Viga unguiculata L. Walp) is the third most important legume food crop in Uganda with the Eastern and Northern regions accounting for most of the production in the country. However, its mean yield is less than 400 ...

Rice Yellow Mottle Virus sobemovirus (RYMV) is highly variable and several resistance breaking strains have been identified. This makes breeding for durable resistant very complicated since a variety proven to be resistance ...

Pseudocercospora fijiensis (P. fijiensis), causal agent of the black Sigatoka disease (BSD) on banana, has spread globally since its discovery in Fiji 1963 in all the banana and plantain growing areas across the globe. It ...

In Rwanda, despite the importance of cassava as staple food, its production is greatly limited by biotic and abiotic constrains leading to poor yields. One of the most important constraints to cassava production is the ...

The whitefly (Bemisia tabaci) (Gennadias, 1889) is a major challenge in cassava production especially for most African regions. This is because most of the varieties used are susceptible to the pest resulting in severe ...

Pseudocercospora fijiensis, causal agent of the black Sigatoka disease (BSD) of Musa spp., has spread globally since its discovery in Fiji 1963 to all the banana and plantain growing areas across the globe. It is becoming ...

This study aimed at quantifying degeneration of cassava planting materials as a result of infection by CBSVs. Four cassava varieties (NASE 14, NASE 15, NAROCASS 1 and TME 204) were evaluated for their responses and ...
