<p>A novel S-methyl N-¢{N-methyl-N-(N,N-disubstituted aminosulfenyl)carbamoyl)oxy!thioacetamidate derivative represented by the formula (I): < IMG > (I) which has insecticidal, miticidal or nematocidal activity comparable to or higher than known methomyl but which is quite low in toxicity to warm-blooded animals as compared to methomyl, is disclosed. In formula (I) above, R1 and R2, which may be the same or different, each represents -X-COOR3, in which X represents an alkylene group having 1 to 6 carbon atoms, and R3 represents an alkyl group having 1 to 8 carbon atoms or a cycloalkyl group having 3 to 6 carbon atoms; R2 further represents an alkyl group having 1 to 8 carbon atoms; a cycloalkyl group having 3 to 6 carbon atoms; a phenyl group which may be substituted with a halogen atom, an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms; a benzyl group which may be substituted with a halogen atom, an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms; or -Z-R4, in which Z represents a carbonyl group or a sulfonyl group, and R4 represents an alkyl group having 1 to 3 carbon atoms, an alkoxy group having 1 to 3 carbon atoms or a phenyl group which may be substituted with a lower alkyl group. An insecticidal, miticidal or continued.... nematocidal composition containing the same, and a process for preparing the same are also disclosed. A method for controlling noxious insects, mites or nematodes by using the same is further disclosed.</p> |
