N-PHENYL-MALEIMIDES WITH HERBICIDAL AND PLANT GROWTH REGULATING ACTION

摘要

Novel derivatives of N-phenylmaleic acid imide and N-phenylsuccinimide have good pre- and post-emergence selective herbicidal properties and they influence plant growth. The compounds correspond to the formula I IMAGE (I) in which ¦: represent a single or double bond, R1 represents hydrogen or fluorine, R2 represents halogen, Y represents C1-C8-alkyl, Z represents hydrogen or C1-C8-alkyl, and A represents hydrogen or a group IMAGE +TR IMAGE wherein R3, R4, R5, R6, R7 and R8 represent customary organic radicals and X represents oxygen, sulphur, SO, SO2, NH, alkylimino or alkenylimino.
