Highlights are presented on the status of knowledge about cassava mosaic disease (CMD) and its causal agents in Nigeria. The disease occurs in all the agroecologies where cassava is grown, from the humid forest in the south to the semiarid and arid agroecologies in the north. The severity is gene...

Many virus diseases of plants and probably all diseases caused by mycoplasma-like organisms (MLOs) are transmitted by insect vectors. In this review the vector insect groups of viruses and MLOs on tropical food legumes are discussed. An overview is given quoting examples of the relations between ...

Deux virus du niébé (Vigna unguiculata), le virus de la marbrure du niébé et le virus de la mosaïque jaune du niébé, ont été étudiés. Les deux virus ont été identifiés et caractérisés à l'aide de la gamme de plantes indicatrices et de méthodes sérologiques. Les deux virus sont très répandus dans ...

The base section of the ACMV-susceptible clone 60506 recorded the highest disease incidence and severity relative to all other sections of the moderately resistant clone TMS 4(2)1425 and the resistant clone TMS 30001. However, in all clones, the base section recorded higher disease than either th...
