Abstract The invention relates to new inclusion complexes of piperonyl butoxide formed with cyclodextrin. The new complex of the invention can be prepared by reacting cyclodextrin or a solution thereof formed with water and/or an organic solvent having 1-4 carbon atoms, preferably ethanol with piperonyl butoxide or a solution thereof formed with an organic solvent having 1-4 carbon atoms, preferably ethanol at a temperature between 20° C. and 90° C., whereby the piperonyl butoxide is used in an amount of 0.6-1.5 moles related to 1 mole of cyclodextrin. The complexes of the present invention synergize the pesticidal effect of known insecticides and fungicides to a much higher extent of known insecticides and fungicides to a much higher extent than piperonyl butoxide used per se.
An inclusion complex of piperonyl butoxide and cyclodextrin, wherein the piperonyl butoxide is present in an amount of 0.6 to 1.5 moles relative to 1 mole of cyclodextrin.
