Definitions

  • the present invention relates to a system for applying an active substance fluid containing an active substance, in particular an active substance effective against plants and/or insects.
  • Passive systems usually consist of plastic elements in which the active ingredient is incorporated or which contain the active ingredient in another form, e.g. as a liquid, and release it through evaporation or osmotically (diffusers).
  • Electromechanical systems often include active ingredient containers (spray cans), some of which are under pressure and are then operated electromechanically.
  • the passive diffusers follow a very simple principle, as they do not contain any mechanically moving parts.
  • the potentially expensive active ingredient is released continuously, e.g. even when no active ingredient is needed, such as at certain times of the day or in certain weather conditions.
  • many units are required per hectare of agricultural land. After the active ingredient has been released, these systems must be collected and disposed of.
  • Another disadvantage is that the release of the active ingredient can no longer be controlled once it has been set in motion. It is also not clear whether the system still contains active ingredient and can therefore still release it.
  • the electromechanical systems are characterized by the fact that a spray can be triggered at specific intervals using an electromechanically driven element in a pressurized container. This leads to significantly fewer units required per hectare than with passive diffusers. Nevertheless, such systems have single use, there are many components that have to be disposed of or recycled. In addition, a relatively complex construction (electronics, pressure vessel, valve, actuators, etc.) is required.
  • the active ingredient itself is often the most expensive component in all of these existing systems, so the active ingredient that is released into the environment permanently (diffusers) or at regular intervals (electromechanical systems) with these existing systems is used rather wastefully.
  • active ingredients are released and consumed even when they have no effect at all, for example when the pests are naturally inactive due to the prevailing weather conditions or the current time of day.
  • the pressure vessels of the electromechanical systems are also classified as hazardous goods during transport, which means additional effort when shipping the goods.
  • the invention is therefore based on the object of specifying a system for applying an active substance fluid containing an active substance, in particular an active substance effective against plants and/or insects, which is characterized by a high degree of controllability of the active substance release, a simple structure and easy recyclability and reusability of its components.
  • a system for applying an active substance fluid in particular an active substance effective on plants and/or insects, which comprises the following components: a) a first module, comprising an electrochemical gas development cell and a control module controlling the gas rate of the gas generated by the gas development cell; b) a second module connectable to the first module, comprising a container for the active substance fluid containing the active substance with an active substance outlet, wherein a delivery pressure built up by the gas generated by means of the gas development cell causes an active substance to be released to the active substance outlet; and c) a third module connectable to the second module, comprising an application element which delivers the active substance provided at the active substance outlet to the plant and/or the insect/organism and/or the environment.
  • the electrochemical gas development cell technology used in the present invention is therefore suitable for providing a market-ready product for the targeted and active ingredient-saving release of, for example, pheromones to protect plants against pests. Due to the small size, the simple construction, the self-sufficient mode of operation and the controllability of the active ingredient release using a very simple electronic circuit, a system can be built that can release active ingredients according to definable and specifiable criteria and thus uses significantly less active ingredient and resources than existing systems.
  • the gas development cell technology can be expanded with additional electronic elements, such as sensors and/or control programs, in order to make the system even more efficient and intelligent or to provide additional control and programming functionality.
  • the modular structure of the system means that all components can be highly reused.
  • the first module which contains the gas generation cell
  • only the batteries need to be replaced from time to time.
  • a new active ingredient container is provided, whereby the empty container can even be recycled in the manner of a deposit system, which can also be commercially worthwhile if glass containers are used.
  • the third module can, under certain circumstances, be used more or less permanently, if necessary interrupted by a short cleaning phase.
  • control module can be designed to adjust the gas rate depending on the time of day and/or the humidity and/or the temperature and/or the prevailing weather conditions and/or by targeted manual intervention.
  • the application element can have a structure for dispensing of the active substance, through which the active substance can be released by contact on a contact surface and/or by evaporation/diffusion.
  • connection of the first module to the second module and/or the connection of the second module to the third module is designed as a plug connection or as a snap-in connection or as a bayonet connection or as a screw connection.
  • Figure 1 shows a schematic representation of the basic structure of a first system for dispensing an active substance fluid containing an active substance
  • Figure 2 shows a schematic representation of the basic structure of a second system for dispensing an active substance fluid containing an active substance
  • Figure 3 shows a schematic representation of the basic modular structure of a system for dispensing an active substance fluid containing an active substance, (a) the assembled system and (b) the modular structure of the system, comprising three modules; and
  • Figure 4 shows a schematic representation of the basic modular structure of a system for dispensing an active substance fluid containing an active substance, (a) in side view and (b) in perspective.
  • the present invention uses the principle of displacement by means of gas to convey active substances, such as pheromones, from a container containing an active substance fluid into an application element, such as an evaporation element, so that the active substance is released into the air, for example.
  • active substances such as pheromones
  • an application element such as an evaporation element
  • the active substance can be released very economically and in a dosage that is optimally tailored to the behavior of possible pests.
  • the principle can be based, for example, on evaporation of the active substance over the surface of the evaporation element, but semi-active (e.g. combination with a fan) or active (e.g. heated surface, nebulization via ultrasound, etc.) evaporation is also conceivable.
  • the control of the amount of active ingredient released and its release time is set via the electronic control module, possibly equipped with a time control, a current control and sensors (temperature, brightness, humidity, etc.).
  • the current control and thus the gassing rate can be implemented via a photoresistor.
  • the installation of a communication element e.g. for external or central starting of the active ingredient release or for networking several of these systems, is also conceivable.
  • this combination of a gas development cell 4 as a drive for the active ingredient delivery, together with an active or passive evaporation element 2 and a simple control of the active ingredient release by means of a photo resistor or a possibly somewhat more complex control module 6, is very well suited to use active ingredients, such as expensive pheromones, in a more targeted and economical manner and to increase their efficiency in a simple and cost-effective manner.
  • the active ingredient is a component of an active ingredient fluid 5 and is provided in an active ingredient container 1.
  • a first module 3 serving as a drive unit for the gas development comprises at least one gas development cell 4, which can also be supplemented with additional batteries if necessary. This first module 3 is mounted on the active ingredient container 1 so that a gas-tight connection is created.
  • active ingredient fluid 5 which contains the actual active ingredient (e.g. the pheromone), is delivered to the passively designed evaporation element 2 and can then evaporate into the environment, which is represented by reference number 11.
  • the photo sensor photo resistor
  • the photo sensor can be used to ensure that the gas development cell is actively operated as long as the brightness falls below a certain limit value of the photo sensor.
  • the active ingredient can then only be released into the environment, for example, under appropriate night-time lighting conditions.
  • the temperature and air humidity can also be measured, for example, and/or current weather data can be received via data communication 10 with the control module 6, so that the active ingredient is not released if the target insects do not swarm out even in their actual nocturnal phase due to the weather being too cool and/or wet conditions and/or the air humidity being too high or too low.
  • this also applies in an analogous manner to pests that are active at dusk or during the day.
  • Figure 2 is basically very similar to the system shown in Figure 1 because the two systems only differ in the presence of a piston 8 in Figure 2, with which the active fluid 5 is conveyed. This means that the active fluid does not come into contact with the hydrogen gas generated by the gas development cell, which could be necessary under certain circumstances, for example depending on the composition of the active fluid 5.
  • Figures 3 and 4 once again show the modular structure of the system for dispensing the active ingredient fluid 5 particularly well.
  • the first module, the drive unit 3 is connected to the second module, here the active ingredient container 1.
  • the connection can be designed as a plug-in connection, a snap-in connection, a bayonet connection or a screw connection.
  • the connection between the second module and the third module, here the evaporation element 2 can also be designed in the same way.
  • any number of variants can theoretically be designed for the second and third modules, as is shown in Figure 3 (b) for three variants each.
  • the system can also be designed with a multi-chamber design for the active ingredient container so that several active ingredients can be dispensed simultaneously and separately from one another in one device.
  • the third module is ultimately designed depends on the active ingredient fluid 5 and the mechanism of action of the active ingredient.
  • a contact body could be provided on which the insects or other animal groups such as larvae, worms, snails or the like are attracted by the active ingredient and come into contact with it, thereby setting in motion the desired effect of the active ingredient on the target organism.
