PURPOSE:An insecticidal composition for agriculture and horticulture capable of showing cooperative and synergistic effects on horticultural insect pests such as insects pests in paddy field, fruits, vegetables, etc., in a low concentration, obtained by combining a nitromethylene derivative with an organic phosphoric ester. CONSTITUTION:An insecticidal composition for agriculture and horticulture containing a nitromethylene derivative[e.g., 1-(3-pyridyl-methyl)-2-(nitromethylene) tetrahydropyrimidine, etc.,] shown by the formula I(X is lower alkyl, lower alkoxy or halogen; l is 0, 1 or 2; m is 2 or 3) and an organic phosphoric ester(e. g., fenthion, etc.,) shown by the formula II(X<1> is O or S; X<2> is direct bond of O, S or P and R<3> R<1> is alkyl; R<2> is alkoxy, alkylthio, phenyl, etc.,; R<3> is alkyl, alkenyl, phenyl, etc., or R<2> and R<3> are bonded to P and X<2> to form phospholine ring). |
