Abstract

PURPOSE:To simply provide the stable agricultural chemical-containing granular fertilizer prevented in pulverization and concretion without requiring a drying process by impregnating or covering a fertilizer with an agrochemically active ingredient and subsequently adding white carbon to the treated fertilizer. CONSTITUTION:A mixed fertilizer, a compound fertilizer, etc., which contains one kind or more of ingredients such as a nitrogen compound, a phosphate salt, a potassium compound and magnesia is sieved, and the separated granular fertilizer having a particle diameter of 0.5-5.0mm is charged into a granulating machine or a stirring type mixing machine. A liquid prepared by dissolving or homogeneously dispersing a mixture containing one kind or more of agrochemically active ingredients such as a herbicide active ingredient, an insecticide active ingredient and an pesticide active ingredient and, if necessary, a surfactant, mineral substance fine powder, water-soluble powder or an organic solvent in water is added to the fertilizer so as to impregnate or cover the fertilizer in an amount of 0.5-10wt.% based on the agricultural chemical-containing granular fertilizer. Furthermore, white carbon comprising silicic anhydride or silicic acid hydrate is added in an amount of 0.1-10.0wt.% based on the agricultural chemical-containing granular fertilizer. The mixture is stirred and mixed for approximately 10min, and the fine powder of the mixed product is sieved out with a 0.5mm sieve to provide the agricultural chemical-containing granular fertilizer.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a novel granular fertilizer containing a pesticide component.

[0002]

2. Description of the Related Art Conventionally, many studies have been conducted on agricultural chemical-containing fertilizers that can be applied with agricultural chemicals and fertilizer at the same time, and have been put to practical use. In terms of form, granules are predominant from the viewpoint of uniform dispersibility and safety. The methods for producing this fertilizer containing pesticides can be roughly classified into three methods: a kneading method, a coating method, and an impregnation method at the time of producing a fertilizer. The method of kneading when fertilizer is produced can be produced with ordinary chemical fertilizer production equipment, but it is practically difficult because there is a risk of pesticides being mixed into general chemical fertilizer. Since it is possible to do so, there is an advantage that pesticide components are not mixed in the fertilizer factory, but after coating with a water-soluble binder, etc., a drying process is necessary to prevent the formulation from solidifying, and drying equipment and Exhaust gas removal equipment is required. The impregnation method is a method of dissolving a pesticide in a high boiling point solvent and impregnating it with fertilizer.
The range of application is limited because the types of pesticides or solvents are limited and the oil absorption capacity of fertilizers is also limited.

As described above, there are many problems in the method for practically producing the agricultural chemical-containing granular fertilizer, and there has been a demand for a simple and stable method.

[0004]

The problem to be solved by the present invention is to produce a pesticide-containing granular fertilizer easily and stably without the need for a drying step, and to prevent pulverization and solidification of the obtained preparation. To provide a method of prevention.

[0005]
