Growth Stages
Top of pageMeans of Movement and Dispersal
Top of pageVector Transmission
EMoV has no known vector. However, another Ilarvirus (Tobacco streak virus) is transmitted by thrips which damage the leaves when feeding and so allow the entry into plants of viruliferous pollen. As EMoV has been detected in pollen of one natural host (lilac), the virus may be similarly transmitted.
Seed Transmission
EMoV is transmitted in seeds of infected elm (Jones and Mayo, 1973). The possibility of seed transmission in other hosts has not been tested adequately.

Diagnosis
Top of page
EMoV is transmitted mechanically in sap to herbaceous test plants. Chenopodium quinoa is the most sensitive test species, leaves of which develop a faint systemic mosaic followed by mottling 7-10 days after inoculation (see Pictures). Necrotic local lesions develop in Phaseolus vulgaris (see Pictures) and Vigna unguiculata. Several other test species, including those of Nicotiana are infected systemically but develop no symptoms (Jones and Mayo, 1973).
The virus is readily detected serologically in plants using ELISA and other serological methods (Uyeda and Mink, 1983).
Similarities to Other Species/Conditions
Top of pagePrevention and Control
Top of pageDue to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.
As EMoV is possibly transmitted between plants through infected pollen and is seedborne, effective control is best achieved by planting virus-tested material away from likely sources of infection.References
