- Sulfamoylphenylureas
-
The N-acylsulfamoylphenylureas of formula I below are suitable as counter-agents (antidotes or safeners) for protecting cultivated plants from the phytotoxic action of herbicides. Suitable crops are preferably cereals, soybeans, sorghum, maize and rice, and suitable herbicides are sulfonylureas, chloroacetanilides and aryloxyphenoxypropionic acid derivatives. The N-acylsulfamoylphenylureas have the formula I STR1 wherein A is a radical selected from the group STR2 R1 is C1 -C4 -alkoxy or each of R1 and R2, independently of the other, is hydrogen, C1 -C8 alkyl, C3 -C8 cycloalkyl, C3 -C6 alkenyl, C3 -C6 alkynyl, STR3 or C1 -C4 alkyl substituted by C1 -C4 alkoxy or by STR4 or R1 and R2 together form a C4 -C6 alkylene bridge, or a C4 -C6 alkylene bridge interrupted by oxygen, sulfur, SO, SO2, NH or by --N(C1 -C4 alkyl)-, R3 is hydrogen or C1 -C4 alkyl, Ra to Rh, Rx and Ry are as defined in the disclosure.
