Beschreibung
Zusammenfassung:	According to the present invention there is provided a synergistic insecticidal composition containing more than one active ingredients and being harmless to environment characterized by comprising in an amount of from 0.001 to 99 % by weight a synthetic pyrathroide of the Formula (I) (I) - namely substantially only the 1RtransS and 1StransR enantiomer-pair (Ib) out from the possible eight isomers - optionally in admixture with an amount of up to 100 % by weight of one or more activator(s) and auxiliary agent(s), particularly antioxidants, stabilising agents, wetting agents, emulsifying agents, dispersing agents, antifoam agents, diluents and/or fillers. The enantiomer-pair Ib consisting of the 1RtransS and 1StransR isomers is new and the invention also relates to the said new enantiomer-pair and a process for the preparation thereof. The advantage of the insecticidal composition of the present invention is that it is less toxical towards warm-blooded animals and useful parasites and is therefore much less harmful to the environment.
