ANELLATED (OXA)HYDANTOINES AND THEIR USE AS HERBICIDES

摘要

Compounds with herbicidal properties should be effective in the smallest possible concentrations and be rapidly biodegradable. The compounds proposed by the invention are intended for use as herbicides and to meet the above requirements. Proposed are compounds of formula (I), in which R1 to R4 are hydrogen or an optionally substituted organic group and Q is an optionally substituted aromatic group. These compounds are readily biodegradable and have herbicidal properties. The compounds are suitable for use as non-selective herbicides or on crop plants, either pre- or post-germination.
