Description

The 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.

Known are applicator devices in which a fertilizer rod introduced into the potting soil is (see DE G 8703761 U1, DE-A 1827977). The used Applicator but remains during the fertilization in the earth until the fertilizer bar consumes is or removed again. The applicators are therefore used to control the fertilization process and for easy removal of fertilizer sticks.

Of the However, the present invention is the solution of another object based. For The home and garden area will be many plant protection products and / or fertilizer in the form of shaped bodies (e.g., tablets or sticks) offered. The disadvantage here is that the user of these funds the moldings must apply itself. The funds achieve an optimal effect only if this deep into the soil or growth medium up in the root area of the plant to be treated are introduced. For the optimal placement, the user must therefore by hand the molding in press the soil. Insofar as the application is admissible with bare hands, The user dirty his hands in an unpleasant way. In addition, can the molded body when impressed into the soil with a finger not arbitrarily deep in the root area pressed the plant become. When applying pesticides must be at This Appliziervorgang also mostly gloves are worn.

It There was therefore a need for the application process for the user the plant protection and / or fertilizer to simplify.

• a) einem Formkörper (1), der einen agrochemischen Wirkstoff und/oder Dünger enthält, und
• b) einer Vorrichtung, die einen lang gestreckten Schaft (2) aufweist, der am unteren Ende so geformt ist, dass ein Hohlraum (3) zur Aufnahme eines Formkörpers entsteht.

The solution of this object is achieved by an applicator set for plant protection products and / or. Fertilizer consisting of

• a) a shaped body ( 1 ) containing an agrochemical active ingredient and / or fertilizer, and
• b) a device having an elongated shaft ( 2 ), which is formed at the lower end so that a cavity ( 3 ) is formed for receiving a shaped body.

With the applicator set according to the invention eliminates the inconvenient application of the moldings per Hand.

The shaped body ( 1 ) is in the application with the set according to the invention initially by a clamping action in the cavity ( 3 ) easily fixed. The cavity is adapted to the molding 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 pulling out the applicator from the soil or growth medium, the now clamped in the soil or the growth medium moldings from the cavity dissolves ( 3 ) of the shaft ( 2 ) and remains in the desired position in the ground.

Due to the elongated shaft ( 2 ), which is preferably made of plastic, is an optimal placement in the lower root area of the plant in their growth medium possible. Preferably, the upper end of the shaft is made wide to facilitate insertion of the applicator device into the ground. In order to achieve an optimal fertilization / crop protection effect, the shaft is preferably just as long that it is an application of the molding ( 1 ) in the main root system of the plant to be treated. Particularly preferably, the elongated shaft ( 2 ) has a length of 10 to 25 cm, most preferably of 12 to 20 cm, as this provides a suitable application depth for the treatment of most plants.

surprisingly way With the application aid, the user is able to achieve such secure application of the Moldings, that the desired Effect (fertilization effect or crop protection effect) reliably occurs.

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

advantageously, can the shaft in this embodiment be formed flat or wide as far as the upper end, so that when pushing out of the molding the stamp head hits the upper end of the shaft and not be pushed through can.

This embodiment has the advantage that the clamping action of the molding in the cavity before the application can be firmer, which simplifies the handling of the applicator set, since the molding less easily from the applicator before direction 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 is the cavity size adjustable, so that standard shaped body different size applied can be. The clamping effect can with a size-adjustable cavity a spring located inside the shaft can be achieved.

According to a further preferred embodiment of the invention, the cavity encloses ( 3 ) at least 30%, preferably at least 50% and particularly preferably at least 70% of the volume of the shaped body ( 1 ), When the molded body is clamped fixed in the cavity. Due to the extensive enclosure of the shaped body, a breakage of the molded body during impressions in the soil or the growth medium is avoided. Rod-shaped moldings are so much better to apply.

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

When fertilizer contain the moldings preferably organic and inorganic nitrogen-containing compounds like urea; Urea-formaldehyde condensation products, amino acids, ammonium salts and nitrates, further potassium salts (such as chlorides, sulfates and Nitrates) and phosphoric acid or salts of phosphoric acid (such as potassium salts and ammonium salts). Furthermore, the fertilizer Salts of micronutrients (such as manganese, magnesium, iron, boron, copper, zinc, molybdenum and cobalt) as well as Plant hormones (such as vitamin B1, and indole-III-acetic acid). The fertilizer is preferred a commercial one Complete fertilizer.

The Main constituents nitrogen, potassium and phosphorus can be found in wide limits are varied. Usually are contents of 1 to 30 wt .-% of nitrogen (preferably 5 to 20 Wt .-%), 1 to 20 wt .-% potassium (preferably 3 to 15 wt .-%) and 1 to 20 wt .-% phosphorus (preferably 3 to 10 wt .-%) used.

1 shows a perspective view of the application device with a punch and a clamped fixed molding.

The device has an elongate shaft ( 2 ), which is cylindrical over its entire length and widens in the lower area so that a cavity ( 3 ) is formed. The cavity is thus on the tablet-shaped molded body ( 1 ) adapted that the molding is clamped fixed in the cavity. The corners of the molding are slightly rounded to facilitate penetration into the soil or growth medium. Inside the shaft ( 2 ) is a stamp ( 4 ) introduced, which emerges from the upper end of the shaft and there his stamp head ( 5 ) Has. By pressing the stamp ( 4 ), the molding can be pressed out of the cavity. Thereby, the underground detachment of the molded body is made possible by the user when the molded body has been well placed in the soil.

To Placement of the molding in the soil or growth medium, the application device after pulling out of the soil or the growth medium again to Application of further moldings be used.
