3-fuoropyridyl-2-oxy-phenoxy derivatives having herbicidal activity

Novel acylated hydrazinomethylphosphonic acids, hydrazinomethylphosphonates, hydrazinomethylphosphinic acids, hydrazinomethylphosphinates or hydrazinomethylphosphine oxides of formula I below are able as 'antidotes' or 'safeners' to protect cultivated plants from the phytotoxic action of herbicides. Suitable crops are preferably maize, sorghum, cereals, rice and soybeans and the herbicides employed are in particular chloroacetanilides.

Novel acylated hydrazinomethylphosphonic acids, hydrazinomethylphosphonates, hydrazinomethylphosphinic acids, hydrazinomethylphosphinates or hydrazinomethylphosphine oxides of formula I below are able as 'antidotes' or 'safeners' to protect cultivated plants from the phytotoxic action of herbicides. Suitable crops are preferably maize, sorghum, cereals, rice and soybeans and the herbicides employed are in particular chloroacetanilides. The acylated hydrazinomethylphosphonates, hydrazinomethylphosphinates or hydrazinomethylphosphine oxides have the formula I ##STR1## wherein R.sub.1 and R.sub.2 are each independently hydroxy, alkyl, aryl, phenylalkyl, alkoxy, alkenyloxy, alkynyloxy, aryl or phenylalkoxy, the radicals of which may be substituted,

A process for protecting cultivated plants against aggressive agricultural chemicals is described in which oxide derivatives of the formula ##STR1## are used as antidotes. Either the cultivated area for the cultivated plants or the cultivated plants themselves or parts of the plant (seeds, tubers, stem parts, and the like), as desired, can be treated with these oxide derivatives, which are used as a dressing.

Thiadiazolyl-glyoxylonitrile-2-oxime ether derivatives for protecting

Novel phosphonic acid and phosphinic acid derivatives of the formula I ##STR1## wherein X is hydrogen or chlorine,

Herbicidal phosphonic acid and phosphinic acid derivatives

A process for protecting cultivated plants against aggressive agricultural chemicals is described in which oxime derivatives of the formula ##STR1## are used as antidotes. Either the cultivated area for the cultivated plants or the cultivated plants themselves or parts of the plant (seeds, tubers, stem parts and the like), as desired, can be treated with these oxime derivatives, which are used as a dressing.

Benzoxazolyl-glyoxylonitrile-2-oxime ether derivatives

This invention concerns novel 1,2,4-benzotriazine-di-N-oxide derivatives having the general formula ##STR1## wherein X and Y, each independently of the other, represent hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, and

1,2,4-Benzotriazine-1,4-di-N-oxides

This invention concerns new 1,2,4-benzotriazine-1,4-di-N-oxide derivatives corresponding to the formula ##STR1## wherein X and Y each independently represent hydrogen, alkyl or alkoxy having 1 to 4 carbon atoms, phenoxy, or halogen, and

1,2,4-Benzotriazine-1,4-di-N-oxide derivatives

Quinoxaline-di-N-oxides corresponding to the formula ##STR1## wherein R.sub.1 and R.sub.2 represent hydrogen, alkyl, phenyl, alkanoyl, benzoyl, alkoxycarbonyl, carbamoyl, cyano, amino or together a polymethylene group,

Animal feeds containing quinoxaline-di-n-oxide derivatives

New 3-Imino-1,2,4-benzotriazine-1-oxides of formula I ##SPC1## wherein R represents an alkyl, alkenyl or haloalkyl radical, a phenyl or aralkyl radical optionally substituted by alkyl, alkoxy, haloalkyl, halogen or hydroxy, X and Y each independently represent hydrogen, halogen, an alkyl or alkoxy radical, or one of the two symbols represents a phenoxy or phenylsulphonyl radical optionally substituted by halogen, alkyl, haloalkyl and/or alkoxy which are active against harmful microorganisms are disclosed.
