Morphology
The meaning is compositionally built from its parts: an issue affecting onions that causes yellowing and stunted (dwarf) growth. This is a common descriptive pattern for plant diseases (e.g. 'barley yellow dwarf'), so a B1 learner who knows 'onion', 'yellow' and 'dwarf' can reasonably infer the MWE's meaning.
Etymology
Onion yellow dwarf is a name that describes what the disease does: a virus makes the onion leaves turn yellow and makes the plant stay small, and dwarf is a word that means 'very small'. So the name refers to a disease that causes yellowing and stunted growth in onion plants.
