摘要

The known N-dichloroacetyl-1,2,3,4-tetrahydroisoquinoline of the formula IMAGE is suitable as an antidote (safener) for the protection of cultivated plants against damage caused by herbicidally active acetanilides of the formula IMAGE in which R represents an optionally substituted N-containing heterocyclic radical, X and Y are identical or different and represent alkyl, Z represents halogen, and n represents 0, 1 or 2, and their herbicidally active acid addition salts and metal salt complexes, - or of the formula IMAGE in which R1 represents alkyl, halogen, haloalkyl, alkylthio, alkylsulphonyl, aminosulphonyl, cyano or nitro, R2 and R3 are identical or different and represent hydrogen, alkyl, halogen, haloalkyl or optionally substituted phenyl, R4 represents alkyl or optionally substituted phenyl, and m represents integers from 0 to 5, or of the formula IMAGE in which A represents oxygen, sulphur or the group 2bLNR10, R7 represents hydrogen or alkyl, R8 represents hydrogen, alkyl, haloalkyl, alkenyl, alkynyl, cycloalkyl, halogen, optionally substituted aryl and aralkyl or the groups -OR11, -SR11 and NR10R11, R10 represents hydrogen, alkyl or optionally substituted aryl, R11 represents hydrogen, alkyl, haloalkyl, alkenyl, alkynyl, cycloalkyl or optionally substituted aralkyl, R5 represents alkyl, R6 represents alkyl or halogen, R9 represents halogen, and p represents the numbers 0, 1 or 2.
