In order to screen the fungicides with good control effect on grey mould of cabbage, the fungicides and their combinations with significant bacteriostatic effect were screened by mycelial growth rate method, and the field efficacy test was carried out. The results showed that pyrisoxazole 25.5% EC, boscalid 50% WG, fludioxonil 50%WP, difenoconazole 10% WG and chlorothalonil 75% WP performed excellent activity in inhibiting the mycelia growth of Botrytis cinerea with EC₅₀ values of 0.135 6, 0.213 7, 1.133 2, 5.864 2 and 6.020 4 μg/mL, respectively.Four formula combinations with significant synergistic effect against cinerea were screened. Pyrisoxazole + fludioxonil（1∶3）, pyrisoxazole + difenoconazole（1∶1）, boscalid + fludioxonil（1∶3）, boscalid + difenoconazole（1∶1） had significant synergistic effect against cinerea. The results of field trials revealed that the above-mentioned four compound fungicides had good control effect on Botrytis cinerea of caggage, and the control effect was over 86%. Among them, pyrisoxazole 25.5% EC + fludioxonil 50% WP had the highest control effect of 95.32%. Four compound fungicides mentioned above can be used to control grey mold and reduce application of fungicides.
