A method of combating undesired plant growth in cereals, in particular winter cereals such as wheat and barley, which comprises treating the locus of the cereals with an effective amount of one or more compounds of formula I:in which R, Rand X&#x2014;W have the meaning given in the claims.

Method of combating undesired plant growth on cereals

The novel compounds of formula I:wherein R, A, X, X, X, Z and m have the meaning given in claim 1, and the agronomically acceptable salts or N-oxides thereof, and herbicidal compositions containing such compounds as active ingredients.

Herbicidal pyridine compounds

Herbicidal mixtures

Herbicidal 3,5-difluoropyridines

Synergistic herbicidal mixtures

Herbicidal 2-aryloxy-4-methyl-6-pyrazol-1-yl-pyridines

Herbicidal N-cyclohexadienyl heteroaryloxyacetamides

Herbicidal 2-aryloxy-or 2-arylthio-6-arylpyrimidines

The invention relates to novel compounds of formula I:

The invention relates to methods for protecting cereal crops from injury caused by a herbicidally effective amount of a herbicide, in particular, herbicides selected from the group consisting of AHAS-inhibiting, ACCase-inhibiting and HPPD-inhibiting herbicides, which comprises applying to the crop plant, the seed of the crop, or the soil surrounding the crop or crop seed an effective non-phytotoxic antidotal amount of a benzothiazole derivative of formula I

Herbicidal compositions and method of safening herbicides using benzothiazole derivatives

The novel compounds of formula I: ##STR1## wherein R, A, X.sup.1, X.sup.2, X.sup.3, Z and m have the meaning given in claim 1, and the agronomically acceptable salts or N-oxides thereof, and herbicidal compositions containing such compounds as active ingredients.

The novel cyanopyridines of the general formula (I) ##STR1## (A, B, R.sup.1, R.sup.2, X, m and n are defined in the specification) show selective herbicidal activity. The new compounds can be prepared according to known methods and can be used as herbicides in agriculture and related fields.

Herbicidal cyanopyridines

New herbicidal pyridine and pyrimidine derivatives of general formula (I), ##STR1## wherein Z represents a nitrogen atom or a C--H group; A represents an optionally substituted aryl group or an optionally substituted 5- or 6-membered nitrogen-containing heteroaromatic group; n represents an integer from 0 to 2 and R.sup.1 or each R.sup.1 independently represents a hydrogen atom or an optionally substituted alkyl, alkoxy, alkylthio or dialkylamino group; m represents an integer from 0 to 5 and R.sup.2 or each R.sup.2 independently represents a hydrogen or a halogen atom or an optionally substituted alkyl, haloalkyl, haloalkoxy, alkoxy, alkylthio group or a nitro, cyano or a halosulphonyl group; and X represents an oxygen or sulphur atom.
