PRECISION OF DISCLOSURE: The invention relates to novel derivatives of cyclopropane carboxylic acid having a group alkylthiocarbonyl and a halogen atom, corresponding to formula (I): where R is a saturated or unsaturated alkyl (1-18c), possibly-a substituted cycloaliphatic radical (3-7c) optionally substituted, aryl (6-14c) optionally substituted or an optionally substituted heterocycle, X is fluorine, chlorine or bromine, A is the remainder of a alcohol used in the synthesis of pyrethroids and side chain double bond is E or Z. The invention tion also concerns their preparation. These new derivatives find their application, especially when in the form of compositions containing them, in the fight against plant, animal and local pests. |
