摘要:
The invention relates to novel combined compositions for combatting plant, animal and sanitarian as well as forestry, horticultural and warehouse pests. These compositions contain a pyrethroid-type insecticide as an insecticidally active ingredient and at least one fungicide inhibiting the ergosterol biosynthesis as activity-strengthening agent as well as optionally piperonylbutoxide and other additives.The advantages of the compositions according to the invention consist therein that the activity-strengthening substances used are fungicidal agents widely used and have an advantageous toxicology. The activity-strengthening agent exerts a synergistic effect together with the pyrethroid-type insecticide.The combinations according to the invention bear an outstanding importance in the protection of stored crops.

The present invention relates to synergistic arthropodicidal composition of several pyrethroidal active ingredients causing no damage to warm-blooded organisms comprising pyrethroides and piperonyl butoxide as active ingredient which comprises as pyrethroidal active ingredient 0.1-20% by weight of 1StransR-alpha-cyano-3-phenoxy-benzyl-3- (2,2-dichlorvinyl)-2,2-dimethyl/cyclopropane-cyrboxylate of the Formula I ##STR1## 0.05-10% by weight of cis-trans-tetramethrin (3,4,5,6-tetrahydrophthalimido-methyl(1RS)-cis-trans-chrysantemate) or trans-tetramethrin of the Formula II ##STR2## and a further pyrethroide, 0.1-40% by weight of piperonyl butoxide of the Formula III ##STR3##
摘要:
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 pyrethroid of the Formula /I/ ##STR1## namely substantially only the 1RtransS and 1StransR entantiomer-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, stabilizing 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.
