Abstract
Fungicide sensitivity of Botrytis cinerea was monitored with a rapid sensitivity test, using toothpick on protected fruit vegetables in Kanagawa Prefecture. Although a strain of the fungus, which was resistant to both diethofencarb-benzimidazole mixture and diethofencarb-dicarboximide mixture, was frequently detected on tomato and cucumber in 1995, the frequency of the resistant strain was reduced in 1996. On the other hand, a resistant strain to dicarboximide was the most frequently detected on strawberry. The rapid sensitivity test used in this surveillance was laborsaving, reliable and expected to be used widely in practical fields.
