Dolichos yellow mosaic virus
Family : Geminiviridae
Genus : Begomovirus
Acronym : DoYMD
Introduction
Dolichos yellow mosaic disease (DYMD) affects the production of dolichos where ever it is grown in India. First reported in Lablab purpureus in India.
Major Diseases
Yellow mosaic
Geographical Distribution
Throughout where ever the crop is grown.
Particle Morphology
Geminate particles of about 20 nm in diameter.
Transmission Method
Transmitted by a vector Bemisia tabaci (Aleyrodidae) in a semi-persistent manner. Virus not transmitted by mechanical inoculation.
Detection
ELISA and PCR
Host Range and Symptomatology
| Host | Symptoms |
| Lablab purpureus | Bright yellow mosaic patches on the leaves and early infections cause reductions in yield. |
