Abstract

The invention relates to an applicator set for plant-protecting agents and/or fertilizing agents, comprising: a) a moulded body (1) which contains an agrochemical active compound and/or fertilizer, and b) an apparatus which has a long stretched-out stem (2) which is expanded at the lower end to an extent such that the resultantly formed cavity (3) is suitable for receiving the moulded body (1), and to the corresponding use.

Description

Applicator set for pesticides and / or fertilizers

The invention relates to an applicator set for the application of moldings containing an agrochemical active ingredient and / or fertilizer in the root area of plants.

Applicator devices are known in which a fertilizer rod is introduced into the plant soil (compare DE G 8703761 Ul, DE-A 1827977). However, the applicator used remains during fertilization in the soil until the fertilizer rod is used up or taken out again. The applicators are therefore used to control the fertilization process and for easy removal of fertilizer rods.

However, the present invention is based on the solution of another object. For the home and garden sector, many crop protection agents and / or fertilizers in the form of shaped bodies (e.g.

Tablets or chopsticks). The disadvantage here is that the user of this agent must apply the moldings themselves. The funds achieve an optimal effect only if they are introduced deep into the soil or growth medium into the root area of the plant to be treated. For optimal placement, the user must therefore manually push the molding into the ground. Insofar as the Apphication with bare hands is permitted, the user disgusts the hands in an unpleasant way. In addition, the molding can when pressing in the soil with a

Fingers should not be pressed arbitrarily deep into the root area of the plant. When Apphoning of

Pflarizenschutzmitteln must also be worn in this Appliziervorgang usually gloves. There was therefore a need to simplify the application process for the user of crop protection and / or fertilizers.

The solution of this object is achieved according to the invention by an applicator set for plant protection üad / or fertilizers consisting of

a) a shaped body (1) containing an agrochemically active ingredient and / or fertilizer,

and

b) a device having an elongate shaft (2) which is formed at the lower end so that a cavity (3) for receiving a shaped body is formed.

The applicator set according to the invention eliminates the inconvenient application of the moldings by hand.

The molded body (1) is easily fixed in the application with the set according to the invention initially by a clamping action in the cavity (3). The cavity is so to the molding adjusted so that the desired fixation occurs. Then, the applicator is pressed with the molding in the soil or growth medium in the root area of the plant to be treated. When the applicator is pulled out of the soil or growth medium, the molded body now clamped in the soil or the growth medium is released from the cavity (3) of the shaft (2) and remains in the desired position in the soil.

Due to the elongated shaft (2), which is preferably made of plastic, optimal placement in the lower root area of the plant in its growth medium is possible. Preferably, the shank is made broad at the top to facilitate insertion of the applicator device into the soil. In order to achieve an optimal fertilization / crop protection effect, the shaft is preferably just as long that it allows an application of the shaped body (1) in the main root system of the plant to be treated. Particularly preferably, the elongate shaft (2) has a length of 10 to 25 cm, most preferably 12 to 20 cm, since it is thus achieved a suitable application depth for the treatment of most plants.

Surprisingly, with the aid of the application, the user succeeds in applying the moldings so securely that the desired effect (fertilizer effect or pest control effect) reliably occurs.

According to a preferred embodiment of the invention, the shaft (2) is hollow and has within the shaft lying a punch (4) consisting of a stem and a punch head (5), wherein the length of the stem is formed so that by pressing the punch head , which is located on the side of the shaft (2) opposite the shaped body (1), it is possible to push out the shaped body (1) fixed in the cavity in a simple manner.

Voπeühafterweise the shaft in this embodiment may be formed as far flatten or wide to the upper end, so that abuts when pushing out of the molding of the punch head at the upper end of the shaft and can not be pushed.

This embodiment has the advantage that the clamping action of the shaped body in the cavity can be stronger before the application, which simplifies the handling of the applicator set, since the shaped body less easily falls out of the applicator device out. In addition, this embodiment avoids problems in releasing the molding from the cavity in the soil or in the growth medium.

In a further preferred embodiment, the cavity is adjustable in size, so that standard shaped bodies of different sizes can be applied. The clamping action can be achieved in a size-adjustable cavity by a spring located inside the shaft. According to a further preferred Ausruhrungsform of the invention, the cavity (3) encloses at least 30%, preferably at least 50% and more preferably at least 70% of the volume of the shaped body (1), when the shaped body is clamped fixed to cavity by the extensive enclosure of the molded article is Breaking up the mold body during molding m Avoiding the soil or growth medium Rod-shaped moldings are much easier to apply

The shaped article (1) is preferably a rod, a plate, a shaped and dimensionally stable granule or a tablet. The shaped article preferably has a length of 2 to 5 cm and a thickness / width or a diameter of 0.4 to 2 cm

As fertilizers, the shaped bodies preferably contain organic and inorganic nitrogen-containing compounds, such as urea, urea-foaldehyde condensation products, amino acids,

Ammonium salts and nitrates, and potassium salts (such as chlorides, sulfates and nitrates) and

Phosphoric acid or salts of phosphoric acid (such as potassium salts and ammonium salts) Des

Furthermore, the fertilizer salts of micronutrients (such as manganese, magnesium, iron,

Boron, copper, zinc, molybdenum and cobalt) as well as plant hormones (such as, for example, vitamin B1 and indole-HI-acetic acid). Preferably, the fertilizer is a commercial full-strength fertilizer

The main constituents nitrogen, potassium and phosphorus can be varied within wide limits. Usually, contents of 1 to 30% by weight of nitrogen (preferably 5 to 20% by weight), 1 to 20% by weight of potassium (preferably 3 to 15% by weight) and 1 to 20% by weight of phosphorus (preferably 3 to 10% by weight) are used. The microstructure contents are usually in the ppm range, preferably 1 to 1000 ppm

In the following an embodiment of the invention is explained in more detail with reference to the drawing:

Fig. 1 shows a perspective view of the application device with a punch and a clamping fixed molding. The device has an elongate shaft (2), which is cylindrical over its entire length and enhances itself in the lower region so that a cavity (3) is formed. The cavity is thus adapted to the tablet-shaped body (1) The shape of the body is clamped in the cavity is clamped The corners of the Formkorper are slightly rounded to facilitate an impression in the soil or growth medium inside the shaft (2) a punch (4) is inserted, which emerges from the upper end of the shaft and there has its stamp head (5). By printing the stamp (4), the mold body can be printed out of the cavity. This enables the subterranean detachment of the mold body by the user when the mold body m has been well placed

After placement of the shaped body in the soil or growth medium, the application device can be used again after removal from the soil or the growth medium for the application of further shaped bodies
