Abstract
We investigated the optimal application timing of simeconazole (2-(4-fluorophenyl)-1-(1H-1, 2, 4-triazol-1-yl)-3-trimethylsilylpropan-2-ol) as a rice false smut control fungicide using the formulations of simeconazole 20% wettable powder and 1.5% granules. The treatments at 1-2 and 2-3 weeks, respectively, before heading were the most effective treatments in a field test. These periods overlap the optimal application timing of simeconazole for controlling rice sheath blight. Consequently, we consider that the treatment with simeconazole can be used to control both false smut and sheath blight simultaneously.
