Abstract
Abstract Substituted pyridazones of the general formula ##STR1## where R 2 is halogen or alkoxy, R 1 is amino, alkylamino, dialkylamino, alkoxyamino, alkylalkoxyamino, halogen, alkoxy, trimethyleneimino or acylated amino, X is unsubstituted or substituted phenoxy of the formula ##STR2## where R 3 , R 4 and R 5 are each, independently of one another, hydrogen, halogen, nitro, cyano, carboxyl, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylmercapto, haloalkylmercapto, alkylsulfinyl or alkylsulfonyl and Y is hydrogen, cyano, haloalkyl, halogen or nitro, and herbicides which contain these compounds.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
133 words
A substituted pyridazone of the formula ##STR23## where R 2 is halo or alkoxy of 1 to 3 carbon atoms, R 1 is amino, alkylamino, dialkylamino, alkoxyamino or alkylalkoxyamino, where alkyl and alkoxy is in each case of 1 to 3 carbon atoms and the alkyl radicals may be identical or different, halogen, alkoxy of 1 to 3 carbon atoms, trimethyleneimino or amino acylated by ClH 2 CC(O)-- or CH 3 COOCH 2 C(O)--, X is substituted phenoxy of the formula ##STR24## where R 3 , R 4 and R 5 are each, independently of one another, hydrogen, halo, nitro, cyano, carboxyl, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylmercapto, haloalkylmercapto, alkylsulfinyl or alkylsulfonyl, alkyl or alkoxy in each case being of 1 to 4 carbon atoms, and Y is hydrogen, halo, haloalkyl, cyano or nitro.
