Novel diphenyl ether hydrazine derivatives, particularly 2-nitro-5 (nucleus-substituted phenoxy) phenylhydrazine derivatives are provided. They are useful as a selective herbicide having a high herbicidal activity and residual efficacy.

Diphenyl ether derivatives and herbicides containing same

The present invention relates to 2-arylethyl ether or thioether derivatives represented by the following general formula [I]: ##STR1## wherein Ar stands for an aryl group, R.sup.1 stands for straight or branched chain alkyl group of 1 to 6 carbons, R.sup.2 stands for a hydrogen atom, or a methyl or ethyl group, R.sup.3 stands for a halogen atom, or a methyl or methoxyl group, R.sup.4 stands for a hydrogen or halogen atom, or a lower alkyl or lower alkoxy group, and n is an integer of 1 or 2 with the proviso that when n is 2, the groups R.sup.4 may be the same or different, and Y stands for an oxygen or sulfur atom, and also to processes for the preparation of these ethers or thioethers and a use of these ethers or thioethers. These compounds of the present invention have excellent insecticidal and acaricidal activities while the toxicity of these compounds are very low.
