Abstract
Mycelial growth and virulence of the dicarboximide-resistant strains of Botrytis cinerea isolated from greenhouses were compared with those of the sensitive strains after 6 month preservation at 10, 20, and 25C. The resistant strains were significantly inferior to sensitive ones in both mycelial growth on PSA media and virulence to excised kidney bean leaves. Sclerotia of the resistant strains buried in soil during summer were inferior to those of sensitive ones in viability.
