The present invention relates to a hydrazine derivative represented by the formula (I): ##STR1## (wherein each of Ar.sup.1 and Ar.sup.2 is a substituted or unsubstituted phenyl group, a substituted or unsubstituted heteroaryl group, or the like, R.sup.1 is an alkyl group or the like, and A is a divalent radical having --C.dbd.N--N-- or --CH--NH--N-- as a fundamental skeleton), which is a useful compound as an agricultural and horticultural insecticide.

Insecticidal hydrazine derivatives

Novel cyclohexane-1,3-dione derivatives represented by 2-{1-(3-chloro-2-propenyloxyimino)propyl}-5-(1-methyl-1H-pyrazol-4-yl)cycl ohexane-1,3-dione and intermediates thereof are disclosed. The cyclohexane-1,3-dione derivatives have a potent herbicidal effect against a wide variety of weeds and can selectively control injurous weeds at lower dosages. A process for preparing the cyclohexane-1,3-dione derivatives is also disclosed.

Cyclohexadione derivatives, selective herbicidal compositions as well as

A pyrazole oxime derivative represented by the general formula (I) which is useful as an insecticide and fungicide, ##STR1## wherein the structural elements are defined in the specification, and the method of controlling said pests. The compounds represented by the general formula (I) can be synthesized by the methods disclosed in the specification.
