Efficacy of a certain fungicides to control leaf spot disease on chinese mustard was tested at Khao Kho Experiment Station. Iprodione at 30 gm./20 litre of water performed a good control of the disease. The disease severity index were 2.7, 2.36 and 2.77 when the spraying intervals were 5, 10 and 15 days respectively. The control plots showed their severity index between 5.56-5.83 while the maximum index of 6 was used. The seed yield from iprodione spraying plot was higher than the others. Captafol, sprayed with intervals of 5 or 10 days, performed a good control as well. Anyhow, captafol will disappeared from the market within a few year. According to the result of this experiment, iprodione at the rate of 30 gm./20 litre of water, sprayed with 10-15 days interval is recommended to control the disease.
