A novel liquid pesticide composition comprising a pesticidally active ingredient and a polyoxyethylene alkyl ether which has the following features (a) and (b): (a) an HLB value of 6 to 13.5; and (b) a content of 10 to 50 wt % based on the liquid pesticide composition.

Liquid pesticide composition

A pyrazole derivative represented by the general formula (1a) or (1b): ##STR1## wherein R.sup.1 represents a hydrogen atom or a pesticidally acceptable protecting group; R.sup.2 and R.sup.3 represent a phenyl, 1-naphthyl or 2-naphthyl group, or a 5-6 membered heterocyclic ring and the like; R.sup.4 represents a hydrogen or halogen atom, or a alkyl, alkoxy or alkylthio group; and a herbicidal composition containing the pyrazole derivative.

Pyrazole derivative and herbicidal composition

Provided are a pyridine derivative represented by the formula (1): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 each independently represent a hydrogen atom, a C.sub.1-6 alkyl group, a C.sub.1-4 haloalkyl group, a C.sub.1-4 alkoxy group, a cyano group, a nitro group or a halogen atom,
