~7;2~S

This is a divisional application of Canadian patent application number 489,594, filed on Thea August, 1985.
The invention relates -to new sulphonylguanidinopyrimidine derivatives, processes for their preparation and their use as herbicides.
Various guanidine derivatives have been disclosed as potential herbicides in patent specifications (compare DE-AS (German Published Specification) 1,089,210 and East German Patent Specifications 71,016 and Betty have not hitherto achieved relatively great importance as agents for combating weeds and/or regulating plant growth.
Other guanidine derivatives are the subject of prior patents EGOS (European Published Specification) 121,082).
