Leaf spots are round blemishes found on the leaves of many species of plants, mostly caused by parasitic fungi or bacteria.
A typical spot is "zonal", meaning it has a definite edge and often has a darker border. When lots of spots are present, they can grow together and become a blight or a blotch. Fungal spots are usually round or free-form in shape.
In most cases, leaf spots are considered to be only a cosmetic problem, but they can have economic effects on nurseries or in floriculture.
Famous quotes containing the words leaf and/or spot:
“So near to paradise all pairing ends:
Here loveless birds now flock as winter friends,
Content with bud-inspecting. They presume
To say which buds are leaf and which are bloom.”
—Robert Frost (1874–1963)
“My gowns were gorgeous, always low-cut, very décolleté. I wore hardly any makeup, just some lipsticks, that’s all. No lights. Just a baby spot. I wouldn’t have any entrance. They’d play the intro in the dark, and a spot would come on, and there I’d be.”
—Richard Brooks (1912–1992)
