Abstract
Substituted pyrazole compounds of the formula (1). The compounds are synthesized from a pyrazole derivative and a haloalkyleneoxime ester derivative, and have excellent herbicidal effects. Herbicide compositions containing the substituted pyrazole derivatives or hydrazide derivatives thereof as active ingredients possess wide herbicidal spectra, work sufficiently in small dosages, and are sufficiently safe for certain important crops
