Journal Article 2004-03

Autor: Sseruwagi, P. Sserubombwe, W.S. Legg, J.P. Ndunguru, J. Thresh, J.M.

Field surveys in many cassava growing areas of Africa have assessed the incidence and severity of cassava mosaic disease (CMD), populations of the whitefly vector (Bemisia tabaci), and the distribution of cassava mosaic begomoviruses (CMBs). The methods employed differ greatly between countries a...

Convolutional neural network (CNN) models have the potential to improve plant disease phenotyping where the standard approach is visual diagnostics requiring specialized training. In scenarios where a CNN is deployed on mobile devices, models are presented with new challenges due to lighting and ...

A countrywide survey on cassava constraints in D.R. Congo was initiated in 2002 and completed in 2004 with the aim of assessing the health status of cassava in various agro-ecological zones of the 11 provinces of the country. The survey permitted to update the list of diseases and pests that cont...

Bemisia tabaci threatens production of cassava in Africa through vectoring viruses that cause cassava mosaic disease (CMD) and cassava brown streak disease (CBSD). B. tabaci sampled from cassava in eight countries in Africa were genotyped using NextRAD sequencing, and their phylogeny and populati...

To satisfy a growing demand for food, global agricultural production must increase by 70% by 2050. However, pests and crop diseases put global food supplies at risk. Worldwide, yield losses caused by pests and diseases are estimated to average 21.5% in wheat, 30.0% in rice, 22.6% in maize, 17.2% ...

Cassava(Manihot esculenta), a root crop originating in Tropical America, has been called Africa’s food insurance but vital as that is, it has the potential to be much more. Already, cassava provides more than half of the dietary calories for over 200 million people in sub-Saharan Africa (about ha...

Cassava diseases are major production constraints wherever the crop is grown. Although diseases will continue to pose a challenge to cassava producers in the immediate future, tremendous progress is being made in developing control tactics. These range from biotechnological approaches for enhanci...

Cassava mosaic disease (CMD) is a major constraint to sustainable production of cassava (Manihot esculenta Crantz) in Zambia and other sub-Saharan African countries. During a survey conducted between April and May 2014 in six (Western, Northwestern, Northern, Luapula, Lusaka, and Eastern) provinc...
