RODONTICIDE BAIT COMPRISING BRODIFACOUM AND METHOD FOR CONTROLLING HARMFUL TARGET RODENTS

摘要

The invention relates to a rodenticide bait comprising at least one edible excipient for harmful target rodents and a configuration stereoisomer, called the E2 enantiomer, of brodifacoum, excluding a racemic mixture of said E2 enantiomer and of a stereoisomer. configuration, called the E3 enantiomer, of the brodifacoum distinct from the said E2 enantiomer; ○ said E2 enantiomer having, by chromatographic analysis of brodifacoum carried out under special conditions and at a temperature of 21.5 ° C., a retention time t2; ○ said E3 enantiomer having, by chromatographic analysis of brodifacoum carried out under these same conditions, a retention time t3; the retention times t2 and t3 being of values such as t1 t2 t3 t4; t1 and t4 represent retention times of stereoisomers of configuration of the brodifacoum distinct from said enantiomer E2 and from said enantiomer E3.
