Method of protecting a plant propagation material

摘要

The present invention relates to a method for using insecticidally active bicyclic derivatives in the control of insects or representatives of the order Acarina in a plant propagation material, by applying a compound of formula I
wherein X is S, SO or SO 2 ; R is hydrogen, halogen or C 1 -C 4 haloalkyl;
X 1 is O, S or N-R 3 , wherein R 3 is C 1 -C 4 alkyl, C 1 -C 4 haloalkyl or C 1 -C 6 alkoxy-C 1 -C 6 alkyl, or X 1 is N-(4-methoxy-benzyl) or N-(propargyl);
X 2 is N, CH, C-halogen, C-CN, C-O-C 1 -C 4 alkyl, N-(2-chloro-thiazol-5-ylmethyl), C-S-C 1 -C 4 alkyl, C-SO 2 -C 1 -C 4 alkyl, C-S-phenyl, C-SO 2 -phenyl or C-SO 2 -C 1 -C 4 halolakyl;
