Disclosed are novel compounds useful for the control of harmful organisms, harmful organism control agents using the same, and processes for producing the novel compounds. The useful novel compounds according to the present invention include compounds represented by formula (1). The compounds represented by formula (1) have potent activity against harmful organisms, and do not have phytotoxicity against agricultural and gardening plants, as objects to which the compounds of the present invention are applied for preventive and exterminating purposes, and human beings and beasts wherein A represents a bond or an optionally substituted alkylene chain; Rrepresents one or more groups, which may be the same or different, selected from the group consisting of a hydrogen atom, alkoxy, and haloalkoxy; Rrepresents a hydrogen atom, benzyl, alkyl or alkanoyl, in which the groups other than the hydrogen atom may be substituted; and Rrepresents a hydrogen atom, cycloalkyl, cycloalkenyl, aryl or a heterocyclic group, in which the groups other than the hydrogen atom may be substituted, excluding the case where Rrepresents a hydrogen atom, A represents a bond or a methylene chain, and Rrepresent phenyl or cyclohexyl, and the case where A represents an alkylene chain and Rrepresents a hydrogen atom.

Picolinamide derivative and harmful organism control agent comprising said picolinamide derivative as active component

A new agricultural and horticultural fungicide having an excellent control effect is provided. 4-Quinolinol derivatives represented by the following formula: or agriculturally and horticulturally acceptable acid addition salts thereof.

4-quinolinol derivatives and fungicides containing the same as an active ingredient used for agriculture and horticulture

4-Quinolinol derivatives and agrohorticultural bactericides containing the same as active ingredient

A 4-acyloxyquinoline derivative represented by the general formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom, a C.sub.1 -C.sub.18 alkyl, C.sub.2 -C.sub.18 alkenyl, C.sub.3 -C.sub.10 cycloalkyl which may be optionally substituted, phenylloweralkyl, phenoxyloweralkyl, aryl group, a group OR.sup.4, where R.sup.4 represents a lower alkyl or aryl group, or a group ##STR2## where X represents an oxygen or a sulphur atom; R.sup.2 represents a hydrogen atom, a lower alkyl alkyl group or a group --COOR.sup.5 where R.sup.5 represents a hydrogen atom or a lower alkyl group; R.sup.3 represents a hydrogen atom, a C.sub.1 -C.sub.10 alkyl or C.sub.2 -C.sub.10 alkenyl group, provided that R.sup.1 does not represent OR.sup.4 when R.sup.2 is a hydrogen atom and R.sup.3 is methyl; R.sup.2 and R.sup.3 together represent a group (CH.sub.2).sub.m, wherein m is 3 or 4, and W represents a hydrogen atom, 1 to 4 halogen atoms, a lower alkyl or lower alkoxy group which may be the same or different and with which the left-hand nucleus is substituted, provided that the compound wherein R.sup.1 represents methyl, R.sup.2, R.sup.3 and W each represent a hydrogen atom is excluded.
