Abstract
The four isomer compound derived from racemic cis/trans-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid and (S)(cyano)(3-phenoxyphenyl) methanol is twice as effective as cypermethrin against certain insect species, but quite unexpectedly is significantly less toxic to mammals and certain species of fish at rates giving commercial control of target crop insects.
