摘要

Agents containing a) 35 to 60% by weight of the active substance permethrin b) 2, 5-12.5% by weight of imidacloprid or imidacloprid analogue of formula (I): in which R represents hydrogen, residues if necessary substituents of the acyl, alkyl, aryl, aralkyl, heteroaryl or heteroarylalkyl group; A represents a monofunctional group of the hydrogen, acyl, alkyl, aryl series or a bifunctional group that is linked to the Z moiety; E represents an attractive electron residue; X represents the residues -CH = o = N-, the remainder -CH = being able to be linked to the remainder Z instead of an atom of H; Z represents a monofunctional group of the alkyl series, -OR, -SR, or represents a bifunctional group that is linked to moiety A or moiety X, the substituents of the above-mentioned substituted moieties being selected selected from: alkyl from 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, alkylthio of 1 to 4 carbon atoms, halogenoalkyl of 1 to 4 carbon atoms and 1 to 5 halogen atoms, the halogen atoms being the same or different; hydroxy; halogen; cyano; nitro; Not me; monoalkyl- and dialkylamino of 1 to 4 carbon atoms, carboxyl; carbalkoxy from 2 to 4; sulfo (-SO3H); alkylsulfonyl of 1 to 4 carbon atoms, arylsulfonyl of 6 to 10 aryl carbon atoms as well as heteroarylamino and heteroalkylamino; c) 27.5-62.5% by weight of N-methylpyrrolidone d) 0-5% by weight of water e) 0-0.5% by weight of phenolic antioxidants and f) 0-0.5% by weight of organic acids.
