<p>There is now provided a new synergistic fungicidal composition of agricultural and horticultural utilities, which comprises (a) a fungicidal triazole derivative of a particular general formula as a first active ingredient, and (b) a second fungicidal compound selected from among the other fungicidal triazole derivatives, fungicidal imidazole derivatives, fungicidal morpholine derivatives and fungicidal piperazine derivatives as a second active ingredient, and this composition is highly effective to control a fungal disease of plants, especially a powdery mildew of plants caused by a resistant strain of a powdery-mildew fungus resistant to such a fungicidal triazole, imidazole, morpholine or piperazine derivative. There are further provided methods for controlling a fungal disease of plants, especially a powdery mildew of plants caused by said resistant strain of the powdery-mildew fungus, with using said synergistic fungicidal composition or using the two fungicidal compounds separately at a time interval.</p> |
