ABSTRACT:

This is a 371 of PCT/EP98/05659, filed Sep. 7, 1998.
1. Technical Field of the Invention
The invention relates to novel substituted phenyluracils, to processes for their preparation and to their use as herbicides.
2. Background of the Invention
A large number of substituted aryluracils is already known from the (patent) literature (cf. JP-A-04178373-cited in Chem. Abstracts 118:59721; JP-A-05039272-cited in Chem. Abstracts 119:180805; JP-A-05202031-cited in Chem. Abstracts 120:107048; EP-A-545206; U.S. Pat. No. 5,169,430; U.S. Pat. No. 5,344,812; U.S. Pat. No. 5,399,543; WO-A-95/17096; WO-A-97/08953). However, these compounds have hitherto not attained any particular importance.
