FIELD: agriculture.
SUBSTANCE: device for evaporation of volatile substances equipped with a heating element and a tablet for evaporation of volatile substances, comprising at least first and second layers of material, including volatile substances, and separated from each other by the predetermined distance, as well as a layer of impermeable material connected to the said layers and located between the first and second layers which is different in the fact that the tablet is located in the device so that one of the said layers is located closer to the heating element than the other layer.
EFFECT: invention enables to provide a double effect, the tablet consists of two layers of material retaining the substance, so that when it is used in the device for evaporation, different conditions of evaporation affect each layer.
