Abstract: A laminated panel unit (1) comprising at least one image layer (3) between at least two panels (2), wherein for an area-contact gluing of the image layer (3) with neighboring panels (2), one intermediate adhesive layer (4, 4?) is provided on each side thereof, wherein the two intermediate adhesive layers and/or panels following each image layer (3) have a different thermal expansion behavior so that the image layer (3), due to the inhomogeneous laminate, is tensioned in case of temperature changes; as well as a method for producing a laminated panel unit (1), wherein the image layer (3) is connected with area contact on either side thereof with the panels (2) by using intermediate adhesive layers (4, 4?), the intermediate adhesive layers (4, 4?) and/or the panels (2) having a different thermal expansion behavior.

Abstract: A nursery box comprising a growth substrate for rice, rice seeds and an aqueous formulation for treating said rice seeds to protect rice plants against insects for a prolonged period of time.

Abstract: Process for treating rice plants or rice propagation material against insects with a view to obtaining sustained and effective protection of the plant after the sowing period, characterized in that there is applied to the said plants or to their propagation material an effective amount of an insecticide other than an organophosphorus insecticide having systemic properties which is capable of having a long-lasting effect, that is to say even persisting on the growing plant after germination.This process is used with a pyrazole insecticide.The invention also applies to the seeds thus treated and to the nursery boxes containing them.
