ABSTRACT:
2-Halo and 2-alkoxy-5-amino-3-oxo-4-(substituted-phenyl)-2,3-dihydrofuran and derivatives thereof. The 2-alkoxy and 2-fluoro compounds generally exhibit both pre-emergence and post-emergence phytotoxicity and are useful as herbicides and also at low dosages as plant growth regulating agents. The 2-bromo, chloro and iodo compounds are primarily useful as intermediates for the 2-alkoxy and 2-fluoro analogs.
