Zusammenfassung:(A) 2-Amino-pyrimidine derivs. of the general formula (I):- R' and R2 = H, opt. subst. hydrocarbon residues, or, together with N, form a heterocyclic ring. R3 and R4 = H, halogen, opt. subst. hydrocarbon residues, or NO2 X = O or S and R5 = COR6 or SO2R6 where R6 is an opt. subst. hydrocarbon or heterocyclic residue linked directly or via an O or S atom. (B) Salts of (I). Systemic insecticides and fungicides. Alternatively metal salts of (III) may be used without a base.
