Phenoxymethylpyrimidine derivative and use thereof as herbicide

A compounds represented by the formula ##STR1## wherein X represents a fluorine atom,

Halogen-containing compounds, herbicidal composition containing the same

A compound of the formula ##STR1## in which each of X and Y represents a halogen atom, R represents a hydrogen atom, a lower alkyl group or an agronomically acceptable soluble salt ion, R.sup.1 represents a lower alkyl group, R.sup.2 represents a hydrogen atom or a lower alkyl group, and Z represents an oxygen or sulfur atom. This compound is useful as herbicide.

Novel 2-nitro-5-(substituted phenoxy)benzohydroximic acid derivatives

A 1,3,5-triazine derivative represented by the following formula (I) ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4, independently from each other, represent a hydrogen atom or a group selected from the class consisting of linear or branched C.sub.1 -C.sub.6 alkyl groups, C.sub.2 -C.sub.6 alkenyl groups, C.sub.2 -C.sub.6 alkynyl groups, C.sub.1 -C.sub.6 alkyl groups substituted by C.sub.1 -C.sub.6 alkoxy or alkylthio, C.sub.3 -C.sub.6 cycloalkyl groups, a phenyl group unsubstituted or substituted by a substituent selected from halogen, nitro, cyano, lower alkyl, lower alkoxy, lower alkylthio and fluoro-substituted lower alkyl, C.sub.7 -C.sub.9 aralkyl groups unsubstituted or substituted by a substituent selected from halogen, nitro, cyano, lower alkyl, lower alkoxy, lower alkylthio and fluoro-substituted lower alkyl, and alkoxycarbonylmethyl groups having 1 to 6 carbon atoms in the alkoxy moiety; and Y represents a fluoro-substituted C.sub.1 -C.sub.3 alkyl group and a herbicidal use thereof.

Triazine derivatives, herbicidal composition containing them, and method

An acetanilide derivative of the following formula (I) and a herbicide containing one or more of the acetanilide derivative as the active ingredient are described. ##STR1## In the formula, R.sup.1 is a lower alkyl group; R.sup.2 is a fluorine-substituted lower alkyl group; A is ##STR2## B is an optionally substituted pyrazolyl group, an optionally substituted alkoxy group or a hydrogen atom. The acetanilide derivative and the herbicide have a selective weed killing activity to gramiveous weeds.

Herbicidal 2-chloro-2'-fluoroalkoxyacetanilides

2-Chloro-N-(4,6-dimethoxy-5-pyrimidinyl)-N-[1-(1-pyrazolyl)ethyl]acetamide of the following formula: ##STR1## a herbicidal composition comprising a herbicidally effective amount of the compound of formula (I); and a method of controlling weeds which comprises applying a herbicidally effective amount of the formula (I) to the locus where the weeds are growing or will grow.

2-chloro-N-(4,6-dimethoxy-5-pyrimidinyl)-N-[1,(1-py
