Morphology
The meaning 'a virus that causes stunted growth and yellowing of onion plants' is directly derivable from the constituents: 'onion' names the host, 'yellow' and 'dwarf' (in the compound 'yellow-dwarf') describe symptoms, and 'virus' names the pathogen. Although 'yellow-dwarf' is a technical compound, its parts are common and the noun-modifier + virus composition is a standard, cross-linguistically transparent pattern, so a B1 learner who knows the words would likely infer the meaning.
Etymology
Onion yellow-dwarf virus comes from the way the infection looks on plants. It makes the onion leaves turn yellow and the whole plant stay very small, or 'dwarfed', so the name tells you the main signs of the disease.
