Abstract

PURPOSE:To obtain an agrochemical composition capable of sustainedly making use of an agrochemical active ingredient because of enabling the active ingredient to be delayed-released owing to using a water-insoluble alginate as matrix. CONSTITUTION:This agrochemical composition is capable of delayed-releasing its active ingredient as pest-controlling or plant growth-regulating active ingredient owing to using a water-insoluble alginate as the matrix having three- dimensional network structure. This composition is obtained by treating granules containing both the active ingredient and alginic acid or a water-soluble salt thereof with an aqueous solution containing divalent or higher valent cations capable of forming a water-insoluble alginate.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural chemical composition in which the release of an agricultural chemical active ingredient which is a pest control active ingredient or a plant growth regulating active ingredient is controlled, and a method for producing the same.

[0002]

BACKGROUND OF THE INVENTION Various pesticides have been developed and used so far, but if pesticide active ingredients can be gradually released in the environment such as soil or water, then the pesticides can be released. Studies have been carried out because it is possible to impart a long-lasting effect to a composition and use it more effectively, and to expect effects such as reduction of chemical damage to crops. However, there has not yet been found a method for obtaining a sustained release of the agricultural chemical active ingredient.

[0003]

According to the present invention, by using a water-insoluble alginate having a three-dimensional network structure,
It is possible to provide a pesticide composition (hereinafter, referred to as the composition of the present invention) capable of controlling the release of the pesticide active ingredient and having an excellent sustained-release effect, and at the same time, the pesticide composition has a pesticide active ingredient. According to the finding that it can be easily produced by treating a granular material containing alginic acid or a water-soluble salt of alginic acid with an aqueous solution containing a divalent or higher cation capable of forming a water-insoluble alginate. Is.

The composition of the present invention can be manufactured as follows. A mixture of one or more agrochemical active ingredients that are pest control active ingredients or plant growth regulating active ingredients and alginic acid or a water-soluble salt of alginic acid, and if necessary further potentiator, phytotoxicity reducing agent, carrier, surfactant, solvent. ,
Granulation improver, binder, stabilizer, colorant, flavor, etc. are mixed, extrusion granulation, tumbling granulation, compression granulation, stirring granulation,
Granulate by a method such as fluidized bed granulation, and if necessary, perform operations such as crushing, sizing, and shape control, and convert alginic acid or a water-soluble salt of alginic acid in the obtained granules to a water-insoluble alginate. In order to do so, a treatment such as immersing the granular material in an aqueous solution containing a divalent or higher cation capable of forming a water-insoluble alginate is performed. After the treatment, if necessary, operations such as drying, sizing, and shape control can be performed to obtain the composition of the present invention.

Examples of the water-soluble salt of alginic acid used in the present invention include alkali metal salts such as sodium salt and potassium salt, ammonium salt, and the like. Alginic acid or water-soluble salt of alginic acid is a mixture of two or more kinds. You may use it. Examples of the divalent or higher cation capable of forming the water-insoluble alginate include cations such as calcium, magnesium, barium, zinc, nickel, copper and lead, and the aqueous solution containing the cation includes calcium chloride and calcium nitrate. Calcium salts such as calcium lactate and calcium citrate, magnesium salts such as magnesium chloride, barium salts such as barium chloride, zinc salts such as zinc chloride, zinc nitrate and zinc sulfate, nickel salts such as nickel chloride and copper sulfate Examples thereof include aqueous solutions of copper salts, lead salts such as lead acetate, and silver salts such as silver nitrate. Among them, calcium chloride is preferably used. The salts of these cations are usually contained in an aqueous solution in an amount of 1 to saturated weight%, preferably 5 to saturated weight%.
Contained. Alginic acid or alginic acid in a water-soluble salt of alginic acid can be widely used from low molecular weight to high molecular weight, and its molecular weight is usually 500 to 8,000,000, preferably 3000 to 2
It is 000000.
