Abstract：Procymidone drug resistance to cucumber Botrytis cinerea at main cucumber planting regions of Shanxi Province was detected. The results showed that the resistance frequency of 177 strains from 8 regions of Shanxi Province was 81.36 %, and the resistance level was 13.9 times. Among all 177 strains, 34 were sensitive strains, 76 were low resistant strains, 64 were moderate resistant strains, and 3 were high resistant strains. There was no extra-high resistant strain.
