PURPOSE:To provide the title composition markedly enhanced in the activity of the bactericidal compound as a component, thus markedly reduced in its dose, comprising an aralkylamine derivative having bactericidal activity or its acid-adduct salt and the title compound. CONSTITUTION:The objective composition comprising (A) an aralkylamine derivative (or its acid-adduct salt) or formula I (R<1> is halogen; R<2> and R<3> are each lower alkyl; C* is asymmetric carbon atom) having markedly high effects on controlling in particular, of grain powdery mildew and rust and (B) 1-100 (pref. 5-60) pts.wt., per pt.wt. of the component A, of a polyoxyethylene octylphenol ether of formula II ((n) is integer, 5-9) of extremely high safety as bactericidal activity enhancer. As the bactericidal activity of the component A is strongly enhanced in the present composition, it also leads to enable its dosage to be reduced correspondingly. |
