1-Substituted 4-carbamoyl-1,2,4-triazol-5-one derivatives and herbicide

A new 1,2,4-triazole compound is now provided, which is represented by the general formula ##STR1## wherein X may be the same or different and denotes a halogen atom, a (C.sub.1 -C.sub.4)alkyl group, a (C.sub.1 -C.sub.4)alkoxyl group, a (C.sub.1 -C.sub.4)alkylthio group, a (C.sub.1 -C.sub.4) alkylsulfinyl group, a (C.sub.1 -C.sub.4)alkylsulfonyl group, a trifluoromethyl group, a nitro group or a cyano group;

1,2,4-Triazole derivatives and fungicidal composition containing the same

New 2-(substituted-phenoxy)propionic acid derivatives are provided, which have the structure of the general formula: ##STR1## and R.sub.2 is a hydrogen atom or a lower alkyl group. They have a high herbicidal activity to weeds, particularly graminaceous weeds, while they have little or no phytotoxicity to broad leaved crop plants and are therefore useful as selective herbicide.

2-(Substituted phenoxy)propionic acid derivatives and their uses for

Certain new 5,6,7-trichlorobenzoxazolone derivatives are highly active against a wide range of plant fungal and bacterial diseases and have a reduced phytotoxicity. These derivatives are also useful to control the growth of various fungi and bacteria being capable of deteriorating industrial materials.

Benzoxazolone derivatives, processes for preparation thereof and

The present invention relates to pyrazolylpyrimidine derivatives of the formula ##STR1## wherein X, R.sub.1, R.sub.2 and R.sub.3 are as herein defined. These compounds are useful as fungicides in agriculture and horticulture.

Pyrazolylpyrimidine derivatives

A new imidazole compound is now provided, which is represented by the general formula ##STR1## wherein R.sub.1 is naphthyl group, an arylalkyl group, a cycloalkyl group, a cycloalkylalkyl group, an alkyl group, a lower alkenyl group, a lower alkoxy-lower alkyl group or a phenylthio-lower alkyl group or phenyl group or a substituted phenyl group;
