| abstract |
The present invention relates to novel pyridine compounds of the formulae I and II, to their salts, to their tautomers, to their N-oxides, and to the salts of these N-oxides or tautomers. The compounds are useful for combating or controlling invertebrate pests, in particular arthropod pests. The invention also relates to a method for controlling invertebrate pests by using these compounds. The invention further relates to plant propagation material and to agricultural compositions comprising said compounds. n n n n n n n n n n wherein A is a radical of the formulae A1 or A2 n n n n n n n n n n # denotes the binding site to the remainder of formulae I or II; n n is 0, 1, 2 or 3; n Z is O, S or N—R N ; n X 1 is S, O or NR 1a ; n X 2 is OR 2a , NR 2b R 2c , S(O) m R 2d ; n X 3 is a lone pair or oxygen; n R 1 , R 2 and R 3 are, inter alia, hydrogen, n and R A and R N , are as defined in claim 1. |
