Bonide Copper Fungicide RTU - Manual (Page 8)

Leaf and fruit spots are small brown or black spots on the leaf or fruit. They commonly
occur on many of the plants grown around the home and in the garden. These spots can
be caused by a range of fungi and bacteria. Leaf and fruit spots are commonly caused
by fungi belonging to the following genera: Alternaria, Cercospora, Colletotrichum,
Cylindrosporium, Gloeosporium, Glomerella, Gnomonia, Marssonia, Mycosphaerella
(Didymella), Phomopsis, Phyllosticta, Septoria, and Sphaceloma. Spots on leaves
and fruit can expand and grow together. Leaf spot pathogens require water to infect
plants. During wet weather, spots can develop into a
blight, rapidly, killing leaves,
flowers and stems.
