DE4037925A1 - Device for protecting plants from insect attack - has gas-tight container with opening for air supply and opening for tobacco smoke - Google Patents

Abstract

In a device for protecting plants from insect attack, a gas-tight container (1) is provided which has an opening (2) for introducing a supply of air or oxygen, and a second opening (3) which receives tobacco (T) on the inside of the container (1) and on the outside is connected to a gas-tight enclosure (4) in which the plant (P) is placed. The container (1) is provided with a removable cover (5). The opening (2) is fitted with a tube (6) to which a source of pressure (B) is connected, and the opening (3) is fitted with a tube (7) whose inner end may be in the form of a pipe bowl in which tobacco can be placed. Alternatively, the tube (7) may be provided with an internal fitting (10) to which a cigarette or cigarillo can be attached by a sleeve (8).

Description

State of the art: 1. To control insect pests on indoor plants

So far, the fight against insect pests on houseplants with the help of mostly chemical-synthetic insecticides (active ingredients of various chemical nature that poison the pest). These poisons are mainly applied in two different ways:

• a) as liquids in the form of sprays; with this method the Pests either through direct contact with the insecticide or poisoned by its later intake with food (contact and Feeding poisons).
• b) as solids in the form of suppositories which are inserted into the soil of the pot of the plant to be treated; With this method, the plant absorbs the poison with the water, which makes it so poisonous that the pests can no longer live on it (systemic poisons). These pest control methods on houseplants are unsatisfactory for several reasons:
  • - The chemical substances used as insecticides are also harmful to human health. Even when the sprays are used properly, contact via the air and the respiratory tract or the skin is often unavoidable.
  • - The improper storage of both sprays and especially systemic poisons in the household is a source of danger and regularly leads to accidents, especially in children.
  • - The insecticides used also pose a danger to human pets.
  • - Used insecticide spray cans are hazardous waste, but are unfortunately only treated as such in rare cases; As a rule, disposal (including unused containers) takes place in household waste.
  • - The propellants in the sprays are also harmful to the environment (destruction of the ozone layer in the earth's atmosphere).

2. The use of nicotine for pest control

Nicotine is a long-known and previously widely used natural insecticide. Its main characteristics are:

• - It leaves after application as a pesticide no residues as it is relatively exposed to light and air decomposes quickly.
• - So far, no signs of resistance in insects are known become.
• - Nicotine is not toxic to plants.
  The use of nicotine as a pesticide - e.g. B. in greenhouses - has now been replaced by the easier to use synthetic insecticides.

Object of the invention:

The invention is based, insect pests on houseplant the task to fight zen without using human health the long underestimated chemical-syn endanger thetic insecticides.

Solution of the task:

The object is achieved with the help of a closed Container in which tobacco smoke production tobacco, preferably in the form a cigarette that is burned. There are two in the container Openings as air inlet and tobacco smoke outlet. Before commissioning the tobacco is inserted into the exit opening and ignited. By Actuation of a pressure generator, preferably bellows, which except half of the container is connected to the inlet opening is in Container creates an air overpressure, which leads to the burning of the tobacco and pushes the tobacco smoke out through the exit opening. The escape Smoking tobacco smoke is in a gas-tight envelope in which the plant to be treated is caught and there kills the Insect pests.

Effectiveness of the pest control according to the invention:

Use this tobacco smoke developer to control insect pests Houseplants have had excellent results. After 30 minutes Ger treatment of infested plants were all tested insects pests (aphids, mealybugs, whitefly, fringe wing) killed immediately, without causing long-term damage to the plants could be observed. For a plastic bag with a volume of 5 l  the amount of smoke from a cigarette with a nicotine content of 0.9 mg.

Advantages of the invention

This invention makes it possible to smoke tobacco in a simple manner develop and thus house plants from harmful insects to free. Compared to the methods currently used on houseplants pest control with insecticide sprays and suppositories there are the following advantages:

• 1. The control process is for the user and his pets no risk to health.
• 2. No health and environmentally friendly propellants are required does.
• 3. Risks of storage in the household, as with chemical synthesis insecticides.
• 4. There is no hazardous waste.

Detailed description of the device according to the invention

The device according to the invention will now be described with reference to the drawing (a). The device consists of a gas-tight container ( 1 ) in which two openings ( 2 and 3 ) are arranged. One opening ( 2 ) is provided as an air inlet; this is connected to a pressure generator (preferably bellows (B)). The second opening ( 3 ) is provided as a gas outlet, the side of which is located in the container ( 1 ) is shaped in such a way that tobacco, preferably in the form of a cigarette, can be accommodated there; the outside of the container ( 1 ) of this opening opens into a gas-tight sealed envelope ( 4 ), inside of which the plant (P) to be treated is located.
