PURPOSE:To obtain an excellent bactericide for agriculture and horticulture synergistically exhibiting extreme effects against sheath blight and blast of rice by combining a specific pyrazol derivative with a specific amide derivative. CONSTITUTION:1 pt.wt. N-(1,1-dimethyl-2-oxa-4-indanyl)-2-methyl-pyrazol-5- carboxylic acid amide derivative expressed by formula I (R<1> is methyl or trifluoromethyl; R<2> is H, methyl, ethyl or Cl; R<3> is methyl or ethyl) is combined with 0.1-100 pts.wt. amide derivative expressed by formula II (X and Y are H, F, Cl, lower alkoxy; Z is Cl, Br, trifluoromethyl or lower fluoroalkoxy; R is methyl or vinyl) to afford the aimed bactericidal composition for agriculture and horticulture. Said composition exhibits an excellent effect to sheath blight of rice and simultaneously has an excellent controlling effect to blast of rice. |
