<p>Herbicidally active novel 5-amino-1-pyridyl-pyrazoles of the formula <IMAGE> in which R1 represents hydrogen or represents alkyl with 1 to 12 carbon atoms, R2 represents hydrogen, nitro, nitroso or halogen, or represents a radical <IMAGE> wherein R5 represents hydrogen, hydroxyl, alkyl, alkenyl, alkinyl, halogenoalkyl, alkoxyalkyl or alkylthioalkyl, or represents optionally substituted cycloalkyl, or represents optionally substituted aryl, or represents alkoxy or alkylthio, or represents optionally substituted aryloxy, or represents optionally substituted arylthio, or represents alkylamino or dialkylamino, or represents optionally substituted arylamino, R3 represents hydrogen, or represents a radical <IMAGE> or represents a radical -S(O)n-R7, R4 represents hydrogen, or represents alkyl, or represents a radical <IMAGE> or represents a radical -S(O)n-R7, and, in the case where R3 represents an -SO2-R7 radical, also represents an inorganic or organic cation bonded in salt form, and R6 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, alkoxyalkyl or alkylthioalkyl, or represents optionally substituted cycloalkyl, or represents optionally substituted aryl, or represents alkoxy or alkylthio, or represents optionally substituted aryloxy, or represents optionally substituted arylthio, or represents alkylamino or dialkylamino, or represents optionally substituted arylamino, X represents oxygen or sulphur, n represents the number 0, 1 or 2, R7 represents alkyl, halogenoalkyl or optionally substituted aryl and Py represents substituted C-linked pyridyl. Some of the intermediates wherein the 5-position of the pyrazole carries a halogen atom are also new.</p> |
