A typical spot is "zonal", meaning it has a definite edge and often has a darker border. When many spots are present, they can grow together and become a blight or a blotch. Fungal spots are usually round or free-form in shape.[1]
In most cases, leaf spots are considered to be only a cosmetic problem, but they can have economic effects on nurseries or in floriculture.
