Taigu Shanxi 030801 .China) Abstract:Boscalid is a quite new fungicide which is used to control Botrytis cinerea. The report of the resistance to Boscalid m Botrytis ι inerea in China is seldom. In order to clear the sensitivity of Botrytis cinerea to Boscalid. inhibi tion of mycelia growth was used to determine sensitivity of 139 isolates of Botrytis ciηerea from 8 areas in Shanxi prov- ince. The result showed that 137 isolates were relatively sensitive strains , and 2 strains showed low resistance. The percentage of relatively sensitive strains was over 98 %. suggesting that sensitivity of Botrytis cinerea from Shanxi province to Boscalid was relatively high. However. as B. c;nerea is a high-risk pathogen and Boscalid is a middle-risk fungicide , appropriate precautions against resistance development should be taken.
