Isolates of Botrytis cinerea Persoon resistant to iprodione were obtained from three tomato fields in Kanagawa prefecture, Japan. The minimal inhibitory concentration value of iprodione for the isolates was about 25ppm. The isolates were cross-resistant to procymidone and vinclozolin. Resistance to benomyl was also found in all the iprodione resistant isolates in this experiment. The virulence of the isolates on broad bean leaves were correspond to that of sensitive isolates. One of the isolate had an ability to develop the disease even on the tomato leaves that treated with 500ppm solution of iprodione, procymidone, vinclozolin, benomyl or thiophanate-methyl.
