Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pesticide granule composition having good hardness.

[0002]

2. Description of the Related Art In recent years, studies have been made on the use of granules for application of 1 kilogram per 10 ares for the purpose of labor saving in spraying pesticides. In the granules, in order to stabilize the efficacy of pesticide active ingredients and pesticide active ingredients, high boiling point solvent,
The amount of auxiliary agents such as surfactants contained in the preparation is very large. Therefore, when the pesticidal active ingredient is a liquid or the other auxiliary agent is a liquid, there is a problem that the hardness of the granule becomes low because the liquid ingredient is contained in a large amount in the preparation.

Further, in the method of applying granules, mechanical spraying from ridges has been studied, and it is also required to increase the specific gravity of granules in order to increase the flight distance. Hardness of such labor-saving dusting granules is an important physical property in terms of production yield, dusting during storage and transportation, and dusting due to dusting during spraying. However, there is a strong demand for a technique for improving the hardness of granules containing a large amount of liquid components in the preparation.

Conventionally, clay, kaolin, calcium carbonate, talc, gypsum, bentonite and the like have been conventionally used as carriers for granules. However, in the case of containing a liquid component, a method of supporting a liquid component on hydrous silicic acid is generally used as an absorption carrier as a technique for producing a solidified preparation.

However, when a large amount of liquid component is contained in the preparation, in order to obtain granules having good hardness by the conventional method using hydrous silicic acid, a large amount of hydrous silicic acid is added to the preparation. There must be. Therefore, a large amount of granulation water is required at the time of production, it takes a long time to dry, which adversely affects the production efficiency, and the apparent specific gravity becomes small, which causes a hindrance to conventional packaging equipment and machines from ridges. There was a problem that the distance traveled during spraying was shortened, resulting in uneven spraying.

[0006]

The problem to be solved by the present invention is to provide an agricultural chemical granule composition having sufficient hardness and good physical properties with no problem in apparent specific gravity.

Test Example-1 Hardness Disintegration Rate Test of Granules (All Farming Method) Granules were thoroughly sieved with a standard mesh sieve having an opening of 500 μm,
A sample is used which has almost no residue left on the net. 100 g of this sample is precisely weighed and three porcelain balls with a diameter of 30 ± 2 mm and a weight of 35 ± 3 g
Ball mill porcelain pot containing 5g) (inner diameter 100mm
× Inner depth 100 mm: Common name, outer diameter 120 mm, 4 inch pot)
Put in. This ball mill porcelain pot was placed on a variable roller ball mill and rotated at 75 rpm / min for 15 minutes. The contents are thoroughly sieved with a standard sieve of 500 μm, and the passing amount of fine powder Ag is precisely weighed. The hardness collapse rate (%) was calculated by the following formula. The result is first
Shown in the table. The smaller the hardness disintegration rate (%), the higher the hardness.

Hardness disintegration rate (%) = [1-A / precisely weighed sample (g)] × 100

Test Example-2 Apparent Specific Gravity of Granules (Official Method (1700 for Sieve)
μm)) A standard sieve of 1700 μm is placed on a 100 cm ³ metal cylindrical container having an inner diameter of 50 mm. (The distance between the sieving mesh and the upper edge of the container is set to 20 cm.) The sample is put in this and lightly scraped off with a brush to fill the container. Immediately, scrape off the excess using a slide glass to obtain the weight (Ag) of the contents. The apparent specific gravity is calculated by the following formula. The results are shown in Table 1.

Apparent specific gravity = A / 100
