AGRICULTURAL AND HORTICULTURAL FUNGICIDAL COMPOSITION

PURPOSE:An agricultural and horticultural fungicidal composition having reduced application concentration and application frequency for plant blight such as downy mildew of grape, scab of apple, etc., comprising tolcolfos-methyl and N,N-ethylenebis(dithiocarbamate) fungicide. CONSTITUTION:An agricultural and horticultural fungicidal composition comprising 1-99.9wt%, preferably 0.2-80wt% of (A) tolclofos-methyl well-known as a controller for soil blight of plant and (B) an N,N'-methylenebis(dithiacarbamate) fungicide such as N,N'-ethylenebis(dithiocarbamic acid)-manganese, N,N'-ethylenebis(dithiocarbamic acid)-zinc, or N,N'-ethylenebis(dithiocarbamic acid)-zinc manganese complex, etc. which has preventing effect on many plant blight, but has high application concentration and application frequency, and not necessarily sufficient controlling effect as active ingredients in a weight ratio of A:B=(1: 0.1)-(1:10). This agricultural and horticultural fungicidal composition can reduce application frequency, because it shows sufficient controlling effect on plant blights with a lower concentration than that of each single component.
