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:
“With fairest flowers
Whilst summer lasts and I live here, Fidele,
I’ll sweeten thy sad grave. Thou shalt not lack
The flower that’s like thy face, pale primrose, nor
The azured harebell, like thy veins; no, nor
The leaf of eglantine, whom not to slander,
Outsweetened not thy breath.”
—William Shakespeare (1564–1616)
“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)
