Strains of Botrytis cinerea and Mucor mucedo germinated and grew over the range 0.25°C. There were differences in germination rates and growth rates between strains of B. cinerea at any given temperature. Five of the benomyl-resistant strains germinated and grew more slowly than any of the other benomyl-resistant or benomyl-sensitive strains of B. cinerea tested. Strains of Rhizopus stolonifer and R. sexualis germinated and grew between 5 and 25°C, and although some spores germinated at 2°C, subsequent growth of the germ tubes and growth from a mycelial inoculum did not occur. Neither species germinated or grew at o°C.

The effect of temperature on mycelial growth in vitro was consistent with the ability of the strains of the four species to infect strawberry fruits.
