Abstract
New diazine derivatives corresponding to the formula ##STR1## wherein R.sub.1 denotes a heterocyclic-aromatic radical which is optionally substituted by halogen, lower alkyl, aryl, nitro, cyano, trifluoromethyl, carboxyl, R.sub.3 OOC--, (R.sub.3).sub.2 NCO--, (R.sub.3).sub.2 N--, R.sub.3 O--, R.sub.3 SO.sub.2 --, R.sub.3 SO-- or R.sub.3 S--, and R.sub.2 and R.sub.3 independently of one another denote lower alkyl, alkoxyalkyl, alkenyl or cycloalkyl which is optionally bonded via an alkylene bridge, processes for the production of the new compounds, compositions containing these compounds and a process for combating Coccidia.
