Disclosed are a pyrazole compound or a salt thereof, a preparation method therefor, a herbicidal composition and use thereof. The pyrazole compound or a salt thereof has a structure as shown in formula (I): ##STR00001##
wherein, R represents ##STR00002##
wherein, R′, R″, and R′″ represent hydrogen, C1-C4 alkyl, C1-C4 halogenated alkyl, C1-C4 alkoxy or halogen, R′, R″, and R′″ may be the same or different; R.sub.1 represents C1-C3 alkyl; R.sub.2 represents hydrogen or C1-C4 alkyl; R.sub.3 represents hydrogen or C1-C6 alkyl, optionally substituted phenyl, optionally substituted pyridyl, optionally substituted alkenyl, optionally substituted alkynyl, C1-C6 alkyl carbonyl, C1-C6 alkoxyl carbonyl, C1-C6 alkyl carbonyl methyl, etc. A compound having a pyrazole structure not only has excellent herbicidal effect on barnyard grass, but also is safe to rice in post-emergence application. More surprisingly, it also has good control efficacy on barnyard grass resistant to major herbicides, such as penoxsulam, quinclorac, cyhalofop-butyl, propanil, etc.
