PURPOSE: To obtain an insecticide composition exhibiting co-operative and synergistic insect-killing effect with excellent fast-acting property and residual effect and also exhibiting sufficiently satisfactory property in toxicity containing guanidine derivative and organic phosphoric acid esters. n CONSTITUTION: (A) A compound expressed by formula I or salt of said compound (R 1 is homo- or heterocycle group; n is 0 or 1; R 2 is H or hydrocarbon group; R 3 is primary or tertiary amino; X is electron-attractive group; with a proviso that R 1 is not pyridyl when X is CN, or R 1 is heterocycle group for n=0) is mixed with (B) a compound expressed by formula II (Y 1 is O or S; Y 2 is Y 1 or bonding valence; R 4 is alkyl; R 5 is alkoxy, alkylthio, alkylamino or phenyl, etc.; R 6 is alkyl, alkenyl, amino, phenyl or heteroaryl, or R 5 and R 6 form phosphoric ring together with P and Y 2 ) in a ratio of 1 pt.wt. A to 0.1-20 pts.wt. preferably 0.5-10 pts.wt. B and the resultant mixture is contained in the aimed composition. n COPYRIGHT: (C)1992,JPO&Japio |
