A new series of azole derivatives containing silicon were synthesized and evaluated for fungicidal activity against rice sheath blight by submerged application. Among them, 2-(4-fluorophenyl)-1-(1H-1, 2, 4-triazol-1-yl)-3-trimethylsilylpropan-2-ol (9a) exhibited satisfactory efficacy at 12.5 grams per 10 ares.
