Abstract
This invention relates to novel pyrimidinylthioalkane derivatives of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are defined in the specification and A represents hydroxy, and B represents hydrogen or A and B together form a carbonyl group, a process for their production and a method of using said derivatives to combat unwanted plant growth.
