Novel pyrazole derivatives of the general formula (I) ##STR1## wherein R.sup.1 represents an alkyl, haloalkyl, alkenyl, haloalkenyl or phenyl group, R.sup.2 and R.sup.3 each represent a hydrogen or halogen atom, or an alkyl, haloalkyl, alkoxy, alkoxyalkyl or phenyl group, and R.sup.4 represents an alkyl, alkenyl, haloalkenyl or phenyl group, or a heterocyclic aromatic group which contains at least one of oxygen, nitrogen and sulfur atoms and may be unsubstituted or substituted, which are useful as agricultural and horticultural fungicides. The pyrazole derivatives can be produced by reacting compounds of the general formula (III) ##STR2## wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above, and X represents a halogen atom, with aminoacetonitriles of the general formula (IV) ##STR3## wherein R.sup.4 is as defined above, or salts thereof.

Pyrazolecarbonylamine derivatives and agricultural and horticultural

A 2-fluoroethoxy-substituted benzene derivative represented by the general formula ##STR1## wherein X represents an oxygen or sulfur atom, R.sup.1 and R.sup.2 represent a hydrogen atom or a lower alkyl group, n represents 0 or 1, and A represents a group of the general formula ##STR2## in which R.sup.3 and R.sup.4 represent a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a lower alkylthio group, a lower haloalkyl group, a lower haloalkylthio group or a methylenedioxy group, R.sup.5 and R.sup.6 represent a hydrogen atom or a lower alkyl group, and p and m represent 0 or 1. This compound is useful as an active ingredient of insecticidal and acaricidal agents, and can be produced by reacting a compound of the general formula ##STR3## with a compound of the general formula
