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

Sulfonylsemicarbazide derivatives and preservative composition for

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.

4-acyloxyquinoline derivatives and insecticidal or acaricidal

A novel compound having an intense insecticidal activity and a process for producing the same which comprises culturing a strain belonging to the genus Humicola and isolating the compound from the culture.

Compound having insecticidal activity and insecticide composition

Fluorophthalimide compounds represented by the following general formula (I): ##STR1## wherein R each stands for an ethyl group or an isopropyl group, are effective for controlling diseases of agricultural plants, especially diseases caused by microorganisms belonging to the genus Rhizoctonia, represented by sheath blight of rice plants, and diseases caused by Basidomycetes.

Fluorophthalimides and agricultural and horticultural fungicides

This invention relates to novel compounds of the general formula (I): ##STR1## wherein A represents ##STR2## in which B represents a ring-forming residue of a 5- or 6-membered carbon-containing heterocycling ring containing at least one nitrogen atom and which may further contain an oxygen atom in the ring, and R.sub.1 and R.sub.2 are the same or different and each represents an alkyl group having from 1 to 6 carbon atoms, a phenyl group, a phenyl group substituted with an alkyl or alkoxy group having from 1 to 4 carbon atoms or a halogen atom, a benzyl group or a benzyl group substituted with an alkyl or alkoxy group having from 1 to 4 carbon atoms or a halogen atom; n represents 0 or an integer of from 1 to 4 corresponding to the number of X substituents; and X represents a halogen atom, a nitro group, a carboxyl group or a carbamoyl group and when two or more X substituents are present they may be the same or different; agents for controlling agricultural and horticultural plant diseases which contain these novel compounds as active ingredients; and to processes for preparing the novel compounds of formula (I).
