Characterization of natural resistance in cassava against viruses causing the cassava brown streak disease

, 2020
Cassava brown streak disease (CBSD), an emerging virus disease in Eastern Africa, is caused by viruses that pose serious threats to the crop because of destruction in roots. African cassava varieties are susceptible to either of the two viruses causing the disease, cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV).

Resistance to Cassava Whitefly (Bemisia tabaci) among Eastern and Southern African Elite Cassava Genotypes

Insects
Cassava whitefly, Bemisia tabaci, directly damages cassava leaves by feeding on phloem, causing chlorosis and abscission, leading to a yield loss of up to 50%. The pest also causes indirect damage through sooty mold formation.

Predicting the current and future suitable habitats of cassava and cassava brown streak disease in Africa

East African Journal of Science, Technology and Innovation
Cassava (Manihot esculenta) is among the most important staple crops globally. In sub-Saharan Africa, it is cultivated mainly by subsistence farmers who depend directly on it for their socio-economic welfare. However, its yield in some regions has been threatened by several diseases, especially the Cassava brown streak disease (CBSD).

Field evaluation of selected cassava genotypes for cassava brown streak disease based on symptom expression and virus load [PDF]

, 2016
Background Production of cassava (Manihot esculenta Crantz), a food security crop in sub-Saharan Africa, is threatened by the spread of cassava brown streak disease (CBSD) which manifests in part as a corky necrosis in the storage root.

Integrating UAVs and Deep Learning for Plant Disease Detection: A Review of Techniques, Datasets, and Field Challenges with Examples from Cassava

Horticulturae
Cassava remains a critical food-security crop across Africa and Southeast Asia but is highly vulnerable to diseases such as cassava mosaic disease (CMD) and cassava brown streak disease (CBSD). Traditional diagnostic approaches are slow, labor-intensive,

Training population optimization for prediction of cassava brown streak disease resistance in west African clones [PDF]

, 2019
Cassava production in the central, southern and eastern parts of Africa is under threat by cassava brown streak virus (CBSV). Yield losses of up to 100% occur in cases of severe infections of edible roots.

Molecular characterization of cassava brown streak viruses in Mozambique

, 2014
Cassava brown streak disease (CBSD) caused by two distinct ssRNA virus species (CBSV and UCBSV of genus Ipomovirus, family Potyviridae) and transmitted by whitefly (Bemisia tabaci), is a major constraint to cassava production in Africa, including ...
