Abstract

The present invention relates to methods, preferably for controlling and/or preventing infestation of boll weevil in cotton, comprising applying to a crop of cotton plants, the locus thereof, or propagation material thereof, a compound of formula (I), wherein -B 1 -B 2 -B 3 - is —C═N—O—, —C═N—CH 2 —, —C═CH—O— or —N—CH 2 —CH 2 —; L is a direct bond or methylene; A 1 and A 2 are C—H, or one of A 1 and A 2 is C—H and the other is N; X 1 is group X R 1 is C 1 -C 4 alkyl, C 1 C 4 aloalkyl or C 3 -C 6 cycloalkyl; R 2 is chlorodifluoromethyl or trifluoromethyl; each R 3 is independently bromo, chloro, fluoro or trifluoromethyl; R 4 is hydrogen, halogen, methyl, halomethyl or cyano; R 5 is hydrogen; or R 4 and R 5 together form a bridging 1,3-butadiene group; p is 2 or 3.

First claim

The invention claimed is:

1. A method for controlling and/or preventing infestation of insects, the method comprising applying to a crop of cotton plants, the locus thereof, or propagation material thereof, a compound of formula (Ia) or (Ib)
