A disease or pathological condition affecting bud development or sprouting in plants.
From Greek 'blastos' (bud) + 'phthora' (decay, destruction). Created in 19th-century botanical texts to describe various blight and bud-rotting conditions in plants.
Plant diseases often get Greek names to sound official, and this one literally means 'bud destruction'—which is exactly what happens when buds fail to develop properly or rot off the plant before flowering.
