Substituted pyridines and pyrimidines, processes for their preparation and their use as pesticides and fungicides. The invention relates to compounds of the formula ##STR1## in which A is N or CH, R is H, halogen, alkyl or cycloalkyl, R.sup.2 and R.sup.3 are H, halogen or an aliphatic radical or together form a ring, X is O, NH or S(O).sub.q where q=0, 1 of 2, R.sup.4.sub.q is 0-4 radicals selected from the series consisting of halogen, optionally substituted alkyl or alkoxy, cycloalkyl and optionally substituted phenyl, n=0-2, m=1-3 and Y is optionally substituted methylene or imino. The invention furthermore relates to a process for their preparation and for their use as pesticides, in particular as insecticides, acaricides and fungicides. The compounds are furthermore suitable for controlling nematodes, helminths and molluscs, and for controlling endoparasites and ectoparasites in the field of veterinary medicine.
取代的吡啶和嘧啶,它们的制备过程和它们作为杀虫剂和杀菌剂的用途。本发明涉及公式##STR1##中的化合物,其中A为N或CH,R为H,卤素,烷基或环烷基,R.sup.2和R.sup.3为H,卤素或脂肪基或一起形成环,X为O,NH或S(O).sub.q,其中q=0、1或2,R.sup.4.sub.q为选自卤素、可选取代烷基或烷氧基、环烷基和可选取代苯基的0-4个基团,n=0-2,m=1-3,Y为可选取代的亚甲基或亚胺。本发明还涉及它们的制备过程以及它们作为杀虫剂,特别是杀虫剂,杀螨剂和杀菌剂的用途。此外,这些化合物还适用于控制线虫,蠕虫和软体动物,并用于兽医学领域内的内寄生虫和外寄生虫的控制。
