The selective inclusion of the (E)-isomer of mevinphos in beta-cyclodextrin to give a solid
formulation that is insecticidally active and dissolves rapidly in water to provide a clear solution
is discussed/. Thus, beta-cyclodextrin dissolved in distilled water to which mevinphos was added
dropwise. The mixture was colled and the white precipitate collected. The inclusion complex
formed 14% (E)-isomer, 70% beta-cyclodextrin, and 16% water. In trials against Aphis fabae the
inclusion complex had insecticidal activities >100-that of the (Z)-isomer.
