Abstract
Novel substituted aryloxyureas, processes for their production, and herbicides comprising them as active ingredients are provided. The substituted aryloxyureas exhibit an excellent herbicidal efficacy against weeds when applied, for example, to the weeds in a wide range of period from a preemergence stage to a growth stage. The substituted aryloxyureas of the invention have the excellent advantage of maintaining high safety on crops or crop plants in spite of their herbicidal efficacy.
