摘要:
Compounds of the formula (I) ##STR1## where X, n, R.sup.1, R.sup.2 and R.sup.3 are as defined in claim 1 are suitable as antidotes against phytotoxic secondary effects of herbicides in crop plants without adversely affecting the action of the herbicides against harmful plants.
摘要:
Compounds of the formula (I) ##STR1## where X.sup.1 and X.sup.2 independently of one another are halogen or haloalkyl,R.sup.1 is hydrogen, alkyl or alkyloxyalkyl,R.sup.2 is alkyl or haloalkyl, andR.sup.3 is hydrogen, alkyl, alkenyl or alkynyl,can reduce, or entirely compensate, phytotoxic secondary effects of herbicides on crop plants and are therefore suitable as agents for the selective use of herbicides.

摘要:
Compounds of the formula I ##STR1## in which R denotes halogen, hydroxyl, cyano, nitro, (substituted) alkyl, (substituted) alkoxy, (halo)alkylthio, carboxyl, alkoxycarbonyl; (halo)alkylsulf(inyl) (onyl) or -(onyloxy); (halo)phenyl or (halo)phenoxy; X in the 3- or 5-position denotes a (thio)carboxylic acid--or an optionally heterocyclic radical which is derived therefrom; Y denotes halogen, m denotes the number 0 or 1, and n denotes a number from 0 to 5, have valuable plant growth-regulating properties and are suitable, in addition, as safeners for protecting crop plants against phytotoxic side effects of herbicides.

Compounds of the formula ##STR1## in which R.sub.n denotes hydrogen, halogen or alkyl, Z denotes oxygen or sulfur, R.sup.1 and R.sup.2, independently of one another, denote hydrogen, alkyl, alkoxyalkyl, haloalkyl or phenalkyl, or, together, denote a (optionally substituted) C.sub.2 -C.sub.4 -alkylene bridge, and R.sup.3 denotes hydrogen or alkyl, are effective antidotes for protecting crop plants against phytotoxic side effects of herbicides.

Compounds of the formula I ##STR1## in which R denotes halogen, hydroxyl, cyano, nitro, (substituted) alkyl, (substituted) alkoxy, (halo)alkylthio, carboxyl, alkoxycarbonyl; (halo)alkylsulf(inyl)(onyl) or -(onyloxy); (halo)phenyl or (halo)phenoxy; X in the 3- or 5-position denotes a (thio)carboxylic acid--or an optionally heterocyclic radical which is derived therefrom; Y denotes halogen, m denotes the number 0 or 1, and n denotes a number from 0 to 5, have valuable plant growth-regulating properties and are suitable, in addition, as safeners for protecting crop plants against phytotoxic side effects of herbicides.
摘要:
The present invention relates to agents for protecting crop plants from the phytotoxic side effects of herbicides, which agents contain a compound of the formula ##STR1## wherein Y denotes C--H or N,the symbols R.sub.1 independently of one another denote alkyl, halo-alkyl, alkoxy, haloalkoxy or halogen,R.sub.2 denotes alkyl or cycloalkyl,X denotes COOR.sub.3, CON(R.sub.4).sub.2, COSR.sub.3, CN or ##STR2## R.sub.3 denotes an alkali metal or alkaline earth metal, hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, or phenylalkyl, it being possible for phenyl to be substituted by halogen, or trisalkylsilylalkyl or alkoxyalkyl,the symbols R.sub.4 independently of one another denote H, alkyl or cycloalkyl, which can be substituted, or radicals R.sub.4 together with the N atom linking them form a 4- to 7-membered heterocyclic ring andn denotes 1 to 3,in combination with a herbicide.
