Abstract
The present invention relates to herbicidally active pyridyl-/pyrimidyl-pyrimidine derivatives. The invention further provides processes and intermediates used for the preparation of such derivatives. The invention further extends to herbicidal compositions comprising such derivatives, as well as to the use of such compounds and compositions in controlling undesirable plant growth: in particular the use in controlling weeds, in crops of useful plants.
