Container or device for insecticidal agent.

The main patent 2 025 593 relates to an insecticidal agent containing 2,2-dichlorovinyldimethylphosphate (DDVP) in which 5 to 20 percent by weight of dissolved hexachloroethane, p-dichlorobenzene, Naphthalene, a naphthalene derivative, camphor, or quinone are included. With such agents, a neutral carrier substance is impregnated, which is accordingly shaped blocks, slabs or tablets made of plaster of paris, pumice stone, kaolin, bentonite, cotton, wood, cork, Leather, a ceramic material, paper, cardboard, cord, string or felt.

The present invention is based on the object of providing a container of the type mentioned at the outset, in particular for destruction of insects on or in the vicinity of growing plants to create the neutral carrier substance that is associated with the above-mentioned insecticidal agent is impregnated, contains.

This object is basically achieved in that the appropriately shaped and impregnated block, which consists of porous solid and neutral carrier material, in a container is arranged having a support part with a removable cover which is movable to the carrier material partially or to release it completely.

Advantageously, that contains dichlorovinyldimethylphosphate "existing liquid insecticidal agents 5 to 20% by weight of dissolved p-dichlorobenzene (PDCB).

The neutral carrier is preferably made of plaster of paris, pumice stone, kaolin, bentonite, wood, cork, a ceramic material, Paper, cardboard, or a porous plastic material. The use of a ceramic material in the form of a fired plate is advantageous.

The carrier part is preferably made of plastic. This is done, for example, by injection molding. In advantageous Way is the carrier part with ein.Einrichtung for direct attachment to a plant, for example a potted plant. But it can also be set up so that it is in any desired position on the ground in the Surrounding the plants can be arranged. The removable cover can also be made of plastic and simply be slid over the neutral carrier so that the surface of the carrier is partially exposed thereby can that the cover is pushed back.

The invention is explained in more detail below with reference to the drawing using an exemplary embodiment.

In the single figure, a container for a carrier is shown, which is impregnated with the insecticidal agent. That

The support member 1 includes a rectangular, fired ceramic plate 4 which ziden with said Jnsekti agent is impregnated, contains the DDVP and PDGB. The support part 1 is provided with a cover 5 which is pushed onto the ceramic plate 4 with a correspondingly tight fit and, due to this seat, can either be completely or partially removed from the surface of the plate and which can also be pushed back on , in order to maintain the activity of the insecticidal agent for as long as possible.

When using the container according to the invention, it is attached to a suitable place, for example on the trunk of the plant, or on the ground near the plants. The lid is then retracted so that the ceramic plate is partially exposed so that the insecticidal agent vaporize and produce in the plant an atmosphere that is killed by the insect at any of the plant or in its vicinity.
