SLCMV is one of several viruses that cause Cassava Mosaic Disease (CMD), a major disease of cassava in Africa and Asia. This particular virus isolate was reported for the first time in Sri Lanka in 1998, and its most recent emergence registered in 2015, in Southeast Asia. The PestDisPlace Reporter map below, shows the current information available on the occurrence of CMD caused by SLCMV. In all cases, the virus now reported in Southeast Asia, is more than 93% identical in nucleotide sequence to isolates from the South of India and Sri Lanka.

Banana production is seriously threatened by a new strain of Fusarium oxysporum f.sp. cubense (Foc), the tropical race 4 (TR4). This soil-borne fungus causes a disease called Fusarium Wilt (FW), in a diverse range of banana varieties including Cavendish clones and is no longer restricted to East and Southeast Asia. The transboundary spread of this pathogen is of great concern now in Africa and the Americas. The PestDisPlace Reporter map below, shows the current information available on the occurrence and early warining reports of FW caused by Foc TR4.

PMTV is the causal agent of “spraing” disease of potato in temperate regions of the world. The virus induces the formation of necrotic arcs in the tuber flesh, reducing marketable quality. V-shaped chlorosis can also be observed in the leaves when conditions are favourable (low temperature and high humidity). Tobacco rattle virus (TRV, Tobravirus) also induces similar necrotic symptoms in the tuber flesh. The PestDisPlace Reporter map shown below, focuses on PMTV and related pomoviruses that represent an epidemiological risk to the crop. The highest diversity of the viruses has been recorded among isolates from the Andes, while in the rest of world, nucleotide identities range from 98 to 100%.
