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.degree. C. and 90.degree. 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.

Concrete elements and a lifting mechanism are secured against tilting at the time of form removal, and the formwork is fixed in place. In the apparatus, a forming unit, a concreting unit and a form removal unit are provided. The forming unit has a single rigid form adapted to shape the bottom and the sides of the elements or products, is open on top and is assembled for use as required. The form removal unit has means for maintaining the product and the removal unit itself in a fixed position against tilting, as well as means for maintaining the formwork in a fixed position, and means for actuating them.
