blackspot
Fungal rose disease
Blackspot refers to a fungal disease that attacks plants, most notably roses, causing dark spots on leaves that eventually yellow and drop.
The term also designates a stretch of road where accidents occur with unusual frequency: The intersection has been a blackspot for years.
In some contexts, blackspot describes an area with poor mobile phone or radio reception, though dead zone is more common for this sense in American English.
