Identification and Control of Gray Mold in Roses
Symptoms: When gray mold occurs on rose leaves at the leaf margins and leaf tips, it first appears as water-soaked light brown spots that are smooth and slightly sunken, then expands and rots. When flower buds are affected, the spots are grayish-black and can prevent the flower from opening; diseased buds turn brown and die. When flowers are affected, some petals turn brown, shrivel and rot. The gray mold fungus also attacks the branch ends after flowers are cut, and the black diseased area can extend several centimeters downward from the infection point. In warm, humid conditions, the gray mold layer can completely cover the infected area.
