peach blight
Noun: A plant disease, specifically one affecting trees that bear drupes (stone fruits), characterized by symptoms that can include wilting, cankers, and dieback of branches.
This is a technical term used primarily in botany, horticulture, and agriculture. It refers to a pathological condition, not a single specific pathogen, but a category of blight diseases affecting certain fruit trees. * The orchard manager identified peach blight on several young trees. * Controlling peach blight often requires both cultural practices and fungicide applications.
The term can be used more broadly in historical or descriptive contexts about plant diseases. * The spread of the peach blight devastated the local fruit industry in the early 1900s.

"Peach blight" is not a single, universally defined disease in modern precise phytopathology. It historically and colloquially refers to various diseases causing blight symptoms on peach and related trees (e.g., nectarine, apricot). The specific causal agent (e.g., bacterium, fungus) must be identified for accurate diagnosis and treatment.
