Biolistic inoculation of cassava (Manihot esculenta Crantz) with South African cassava mosaic virus

, 2016
Cassava mosaic disease (CMD) is undoubtedly the most widespread disease in cassava (Manihot esculenta Crantz) in sub-Saharan Africa. While African cassava mosaic virus-Kenya (ACMV-KE), African cassava mosaic virus-Uganda (ACMV UG), African cassava mosaic

Disease resistance characterisation of improved cassava genotypes to cassava mosaic disease at different ecozones

Archives of Phytopathology and Plant Protection, 2015
Twenty-two cassava genotypes and eight controls were evaluated in two cropping seasons for resistance to cassava mosaic disease (CMD) at the International Institute of Tropical Agriculture (IITA) fields, located at different ecozones of Nigeria. Disease incidence (DI) and index of symptom severity data were obtained monthly at each location and ...

The cassava mosaic geminiviruses occurring in Uganda following the 1990s epidemic of severe cassava mosaic disease

, 2018
The cassava mosaic geminiviruses (CMGs) isolated from cassava plants expressing mild and severe symptoms of cassava mosaic disease (CMD) in 2002 in Uganda were investigated using the polymerase chain reaction and restriction fragment length polymorphism (

Sensitivity analysis and optimal control for the dynamic mathematical model of cassava mosaic disease

AIP Advances
Cassava mosaic disease (CMD) is found in many countries around the world. This disease is caused by a mosaic virus carried by whitefly. It hurts the growth and yield of cassava, which in turn causes damage to farmers who grow cassava.

Occurrence of cassava mosaic disease and characterization of casual viruses in Mozambique

, 2021
Cassava mosaic disease (CMD) is one of the major constraints to cassava production in Mozambique. In this research, two studies were carried out to monitor the incidence and severity of CMD and its causal viruses in the country.

Cassava mosaic disease in Madagascar: complex epidemiology and evolutionary dynamics of cassava mosaic geminiviruses

, 2016
BACKGROUND and OBJECTIVES Cassava is the staple food for hundreds of millions of people in Africa but its cultivation is seriously constrained by cassava mosaic disease (CMD) in Madagascar and in Africa in general. We have undertaken (1) to identify the cassava mosaic geminiviruses (CMGs) involved in CMD in Madagascar and their epidemiological ...
