PYRIDAZINE COMPOUNDS， METHOD FOR CONTROLLING PEST INVERTEBRATES， METHOD FOR PROTECTING PLANT PROPAGATION MATERIAL and THE PLANT PROPAGATION MATERIAL

The present invention relates to pyridazine compounds of formulae (I) or (Il) and the salts and N-oxides thereof， wherein A is a substituted or unsubstituted oxazole or thiazole or imidazole radical; V is C(RV) or N; W is C(RW) or N; with the proviso that either V or W is N; Rt， Ru， Rv， Rw are H， halogen， C1-C4-alkyl and the like; X1 is S， O or NR1a， wherein R1a is selected H， C1-C10-alkyl and the like; X2 is OR2a， NR2bR2c， S(O)mR2d， wherein m is 0， 1 or 2， R2a is C1-C4-alkyl， C1-C4-haloalkyl and the like， R2b， R2c are H， C1-C4-alkyl， C1-C4-haloalkyl and the like， or R2b and R2c together with the nitrogen atom to which they are bound form a heterocycle， and R2d is C1-C4-alkyl， C1-C4-haloalkyl， C3-C6-cycloalkyl and the like; and R1 is H， CN， C1-C10-alkyl and the like. The present invention further relates to a method for controlling invertebrate pests， to a method for protecting plant propagation material and/or the plants which grow therefrom， to plant propagation material， comprising at least one compound according to the present invention， to a method for treating or protecting an animal from infestation or infection by parasites and to an agricultural composition containing at least one compound according to the present invention.
