| abstract |
The invention relates to insecticidal, miticidal, nematicidal or soil-pesticidal agents for use in agriculture. The aim of the invention is the provision of new agents with a strong insecticidal, miticidal, nematicidal or soil-pesticidal activity. According to the invention, the novel compositions contain novel organophosphorus compounds having a substituted 2-oxo-imidazolidine ring, a substituted 2-thioxo-imidazolidine ring, a substituted 2,4-dioxo-imidazolidine ring or a substituted 4-oxo-2-ring thioxo-imidazolidine ring, wherein a phosphate compound is linked to the nitrogen atom in the 1-position. The organophosphorus compounds according to the invention correspond to the formula I in which, for example, X 1, X 2 and X 3 denote hydrogen or an optionally substituted alkyl, alkoxy or alkylene group and the like. al .; Y1, Y2, Y3 oxygen or sulfur atom; Z carbonyl group or an optionally substituted methylene group; R1 and R2 represent an optionally substituted alkyl group.
