Description

  The present invention is a solid preparation that is sprayed as it is using a spreader without being diluted with water, has a good sprayability in high temperature and high humidity conditions, and has a scattering (drift) during spraying The present invention relates to a suppressed particulate fungicide composition and / or a particulate insecticide composition.

  In recent years, when solid formulations are being sprayed, there is concern about scattering (drift) to the surrounding environment such as other crops and houses and exposure to farm workers. Fine-grained agricultural chemical compositions such as fine granules F (particle size distribution 180 μm to 710 μm), fine granules (particle size distribution 106 μm to 300 μm) and fine granules F (particle size distribution 63 μm to 212 μm) have been developed as few solid preparations I came. These fine granular pesticide compositions have been subjected to many studies exemplified below for the purpose of suppressing the peeling of the agricultural chemical active ingredients from the fine particulate carrier during spraying while maintaining the dispersibility comparable to DL powder. It was.

  In JP-A-49-13338 (Patent Document 1), (a) a non-absorbable or relatively non-absorbable mineral fine powder and (b) an active ingredient (insecticide) spread thereon. , Disinfectant, herbicide, nematicide, and the like) and a vinyl acetate polymer or copolymer. Agricultural and horticultural granule compositions with improved fluidity have been proposed.

  In Japanese Patent Application Laid-Open No. 2003-12406 (Patent Document 2), a solution in which an agrochemical active ingredient that is liquid at room temperature (excluding the insecticide diazinon (generic name)) and an agrochemical active ingredient that is solid at room temperature is dissolved in an organic solvent. Alternatively, the mixture is impregnated and bonded to a non-absorbent granular carrier together with calcined ultrafine amorphous silicon dioxide having an equilibrium water content of 5% or less and an average particle size of 3 μm or less, thereby providing good fluidity and peeling. In addition, there has been proposed an agrochemical granular composition in which there is no dusting due to aging, and peeling of an agrochemical active ingredient is hardly observed even in application using a power spreader, and a simple method for producing the agrochemical granular composition.

  In Japanese Patent Application Laid-Open No. 2003-12423 (Patent Document 3), the insecticide diazinon (generic name) is not oil-absorbed together with calcined ultrafine amorphous silicon dioxide having an equilibrium water content of 5% or less and an average particle size of 3 microns or less. Impregnated pesticidal granular carrier has improved fluidity, no powdering due to peeling, and improved pesticide active ingredient composition with almost no peeling of agrochemical active ingredients even when applied using a power spreader And the simple manufacturing method of this agrochemical granular composition is proposed.

In JP 2009-84183 A (Patent Document 4), a method for producing a pesticide granule or a pesticide granule that performs at least the following (1) to (3) in a mixer (1) Mixing a carrier and a binder liquid Then, a binder layer is formed on the surface of the carrier.
(2) At least a pesticide active ingredient is fixed through the binder layer.
(3) A dehydrating desiccant (such as hemihydrate gypsum) is mixed and dried.
Pesticides with low peeling and scattering properties of active ingredients of agricultural chemicals (general agricultural chemicals such as bactericides, insecticides, insecticidal mixture, herbicides, etc.) without any hot air drying process It describes that it is possible to produce granules or agrochemical powders.

However, the finely divided pesticide composition is generally sprayed in the summer when it becomes hot and humid, and must be stored under high-temperature and humid conditions until it is sprayed. When stored under such conditions, the decrease in fluidity due to moisture absorption of the finely divided pesticide composition causes poor spraying, resulting in the risk of insufficient biological effects, as well as the burden on the spraying machine and the risk of failure. There is. In addition, even a particulate pesticide composition in which exfoliation of the pesticidal active ingredient is suppressed, exfoliation of the pesticidal active ingredient may not be suppressed in the same way even under high temperature and high humidity conditions, and thus a stable biological effect is obtained. Whether it is possible is unknown. Furthermore, there is a concern about the scattering (drift) of the fine granular pesticide composition itself. The above-mentioned Patent Documents 1 to 4 do not describe various problems under these high temperature and high humidity conditions.
Therefore, by a simple and low-cost production method, sprayability is good even under high temperature and high humidity conditions, and it is possible to suppress peeling of the pesticidal active ingredient and scattering of the fine pesticide composition itself even under the same conditions. There is a need for a technique that can produce a stable biological effect.

JP-A-49-13338 JP 2003-12406 A JP 2003-12423 A JP 2009-84183 A

  In view of the conventional drawbacks as described above, the present invention has a good sprayability even under high temperature and high humidity conditions by a simple manufacturing method, and exfoliation and solid formulation of agrochemical active ingredients even under the same conditions It is an object of the present invention to provide a finely divided fungicide composition and / or a finely divided insecticide composition capable of suppressing a scattering (drift) of itself and exhibiting a stable biological effect, particularly a bactericidal effect and / or an insecticidal effect.

  The present inventors have intensively studied to solve the above problems. As a result, by setting the particle size of the fine pesticide composition to 63 to 710 μm and the apparent specific gravity to 1.0 to 2.0, scattering (drift) of the fine pesticide composition itself is suppressed. I found it. Furthermore, among water-absorbing agents that absorb water by chemical adsorption, especially by adopting a water-soluble water-absorbing agent having a water solubility of 3% or more with respect to 100 g of water at 25 ° C. It has been found that a finely divided fungicide composition and / or a finely divided insecticide composition can maintain even better sprayability even under high temperature and high humidity conditions, and the present invention has been completed.

And a water-soluble water-absorbing agent having a water solubility at 25 ° C. of 3% or more based on 100 g of water, and having an apparent specific gravity of 1.0 to 2.0. A fungicide composition and / or a particulate insecticide composition.
(2) The fine particulate fungicide composition and / or the fine particulate insecticide composition according to (1), wherein the water-soluble water-absorbing agent (e) by chemical adsorption is anhydrous magnesium sulfate.

  Since the finely divided fungicide composition and / or the finely divided insecticide composition of the present invention does not require a hot air drying step during production, it can be obtained at a low cost by a simple production method. In addition, even when sprayed under high temperature and high humidity conditions, it not only has good sprayability, but also exfoliates the microbicidal active ingredient and / or insecticidal active ingredient from the microparticulate carrier, and the microparticulate fungicide composition and / or microparticulate Since the scattering of the insecticide composition itself can be suppressed, the drift surface is also excellent, and a stable bactericidal effect or insecticidal effect can be achieved.

Hereinafter, the fine particle fungicide composition and / or the fine particle insecticide composition of the present invention will be described in more detail.
<About sterilizing and / or insecticidal active ingredient>

The specific sterilizing and / or insecticidal active ingredients contained in these are, for example, “Agricultural Chemicals Handbook 2005 Edition” (Japan Plant Protection Association, published on October 11, 2005), “SHIBUYA INDEX 9th Edition”. (SHIBUYAINDEX study group, issued on December 15, 2001), "The Pesticide Manual Event Edition" (published by British Crop Protection Council), and the like.

For example, conventionally known sterilizing and / or insecticidal active ingredients other than those described above can also be applied.
The amount of the sterilizing and / or insecticidal active ingredient added is usually 0.01 to 50% by weight, preferably 0.05 to 20% by weight in the finely divided fungicide composition and / or finely divided insecticide composition. is there.

<About fine carrier>
Examples of the particulate carrier that can be used in the present invention include clay, calcium carbonate, talc, silica sand, bentonite, pumice, zeolite, sepiolite, diatomaceous earth, and attapulgite.
The finely divided fungicide composition and / or the finely divided insecticide composition of the present invention is generally sprayed by a multi-hose equipped with a power spreader, and the composition is from the viewpoint of biological effect, sprayability, drift, and the like. The particle size of the product is preferably 63 to 710 μm, and the apparent specific gravity is preferably 1.0 to 2.0. More preferably, the particle size is 63 to 300 μm and the apparent specific gravity is 1.4 to 1.8. The particulate carrier is not particularly limited as long as the particle size and apparent specific gravity of such a particulate fungicide composition and / or the particulate insecticide composition can be adjusted, but silica sand is particularly preferable. Further, there is no problem even if two or more kinds of finely divided carriers are used in combination.
The amount of the finely divided carrier that can be used in the present invention is usually 40.0 to 99.9% by weight, preferably 70.0 to 99.8% in the finely divided fungicide composition and / or the finely divided insecticide composition. % By weight.

<About solid binder>
The solid binder that expresses adhesive force by intervening water adheres the sterilizing and / or insecticidal active ingredient to the surface of the particulate carrier, and then removes the water to remove the moisture from the particulate carrier and the sterilizing and / or insecticidal active ingredient. Are firmly cross-linked, and the sterilization and / or peeling of the insecticidal active ingredient from the finely divided carrier can be suppressed. Therefore, when using a liquid binder such as glycerin, polybutene, liquid paraffin, etc., since the cross-linked portion of the sterilizing and / or insecticidal active ingredient and the fine particulate carrier is a liquid, the cross-linking is weaker than that of the solid binder, It is not sufficient to suppress drift due to sterilization and / or peeling of the pesticidal active ingredient from the particulate carrier.

Solid binders that can be used in the present invention include natural, semi-synthetic and synthetic water-soluble polymers.
For example, natural water-soluble polymers include starch, gum arabic, tragacanth gum, guar gum, mannan, pectin, sodium alginate, sorbitol, locust bean gum, xanthan gum, dextran, curdlan, pullulan, gelatin and casein. .

  Examples of the semi-synthetic water-soluble polymer include dextrin, cyclodextrin, soluble starch, pregelatinized starch, methylcellulose, ethylcellulose, carboxymethylcellulose, hydroxyethylcellulose, and hydroxypropylmethylcellulose.

  Examples of the synthetic water-soluble polymer include polyvinyl pyrrolidone, polyvinyl alcohol, polyacrylamide, sodium polyacrylate, ethylene-acrylic acid copolymer, polyethylene glycol and polyethylene oxide.

  Among these, starch, dextran, dextrin, cyclodextrin, methylcellulose, ethylcellulose, carboxymethylcellulose, hydroxyethylcellulose, hydroxypropylmethylcellulose, and polyethylene oxide are more preferable, and cyclodextrin, polyethyleneoxide, and carboxymethylcellulose are more preferable.

The solid binder that can be used in the present invention does not require a pretreatment step to make an aqueous solution or an aqueous dispersion in advance, and after sterilization and / or an insecticidal active ingredient and a finely divided carrier are mixed and powdered, By adding and mixing, sufficient adhesive force can be developed between the sterilizing and / or insecticidal active ingredient and the particulate carrier.
The amount of the solid binder that can be used in the present invention is usually 0.1 to 10% by weight, preferably 0.3 to 5% by weight in the finely divided fungicide composition and / or finely divided insecticide composition. is there. When the added amount is less than 0.1% by weight, the drift caused by the active ingredient adhering to the surface of the finely divided fungicide composition and / or the finely divided insecticide composition becomes easy to peel off, Even if it exceeds 10% by weight, the bactericidal effect and / or insecticidal effect exerted is not affected, and if it exceeds 10% by weight, it is disadvantageous in cost.

<About water>
Water is an essential component for sterilization by a solid binder and / or adhesion of an insecticidal active ingredient to a particulate carrier and formation of a crosslinked part. As described above, the solid binder exhibits adhesive ability in the presence of water, and after the bactericidal and / or insecticidal active ingredient is adhered to the surface of the fine particulate carrier, a crosslinked portion is formed by removing water. Therefore, in the absence of water, the solid binder does not exhibit adhesive ability and does not form a cross-linked portion, so there is a concern about sterilization and / or scattering of the insecticidal active ingredient itself.
The amount of water that can be used in the present invention is usually 0.1 to 15% by weight, preferably 0.3 to 10% by weight, in the finely divided fungicide composition and / or finely divided insecticide composition. is there. When the amount added is less than 0.1% by weight, the adhesiveness of the solid binder is insufficient, so that drift caused by sterilization and / or peeling of the insecticidal active ingredient from the fine particulate carrier becomes a problem, and 15% by weight Since the bactericidal effect and / or insecticidal effect exerted even when the amount exceeds 15% is not affected, the amount exceeding 15% by weight is disadvantageous in cost.

<About water-soluble water-absorbing agent by chemical adsorption>
In the fine particle fungicide composition and / or the fine particle insecticide composition of the present invention, the water absorption mechanism is chemical adsorption with water, and the water solubility at 25 ° C. is 3% or more with respect to 100 g of water. The water-soluble water-absorbing agent is important for ease of production, good sprayability maintenance under high temperature and high humidity conditions, and stable sterilization and / or insecticidal effects. That is, at the time of manufacture, the hot air drying step can be omitted by adsorption of free water, which is simple and advantageous in terms of cost. And under high-temperature and high-humidity conditions, it has an action of preventing the fluidity of the composition from being lowered by absorbing moisture, so that it is important for maintaining good sprayability. Further, even if the sterilizing and / or insecticidal active ingredient is produced in such a form that it is incorporated into the water-soluble water-absorbing agent, the water-soluble property does not inhibit the sterilizing and / or insecticidal ingredient release. For this reason, even if dispersion unevenness occurs, a stable sterilization and / or insecticidal effect can be exhibited. Therefore, the properties required for the water-absorbing agent include that the water-absorbing mechanism is chemical adsorption with water (dehydration by chemical reaction with water), and that the water-absorbing agent does not solidify or is only slightly consolidated after water absorption. When the water absorption mechanism is physically adsorbed, water is adsorbed but exists in a free state, resulting in poor spraying due to reduced fluidity of the formulation. Even if the water-absorbing agent by chemical adsorption is solidified after water absorption, such as hemihydrate gypsum, it will affect the dispersibility. Is disadvantageous. Furthermore, when a water-absorbing agent having a water solubility of less than 3% is used, the disinfecting and / or insecticidal component release is inhibited, and the disinfecting and / or insecticidal effect is reduced.

Examples of the water-soluble water-absorbing agent by chemical adsorption that can be used in the present invention include organic acid salts and inorganic acid salts.
The salt of the organic acid and the salt of the inorganic acid are not particularly limited as long as they can capture water as crystallization water and may be hydrates. However, an anhydride having a large amount of crystallization water taken in is preferable from the viewpoint of production and cost. .

  Organic acid salts include trisodium citrate (anhydrous, anhydrous water solubility: 42.5%), disodium succinate (anhydrous, anhydrous water solubility: 34.9%), potassium sodium tartrate ( Anhydrous, anhydrous water solubility: 64.4%), sodium L-tartrate (anhydrous, anhydrous water solubility: 23.2%), calcium lactate (anhydrous, anhydrous water solubility: 3.5) %), Sodium malate (hydration number = 0.5 hydrate, water solubility of 0.5 hydrate: 63.8%) and the like.

  Examples of inorganic acid salts include calcium chloride (anhydride, monohydrate, dihydrate, tetrahydrate, anhydrous water solubility: 74.5%), magnesium chloride (anhydride, hexahydrate). Water, octahydrate, anhydrous water solubility: 54.3%), sodium pyrophosphate (anhydrous, hexahydrate, 10 hydrate, 16 hydrate, 18 hydrate, anhydrous water) Solubility: 7.1%), aluminum sulfate (anhydride, hexahydrate, 10 hydrate, 16 hydrate, 18 hydrate, anhydride water solubility: 38.5%), ammonium ammonium sulfate ( Anhydrous, anhydrous water solubility: 7.1%, potassium aluminum sulfate (anhydrous, anhydrous water solubility: 7.2%), sodium aluminum sulfate (anhydrous, anhydrous water solubility: 40.8) %), Sodium sulfate (anhydrous, dihydrate, heptahydrate, anhydrous water solubility: 19. %), Magnesium sulfate (anhydrous, monohydrate, hexahydrate, heptahydrate, anhydrous water solubility: 36.4%), sodium phosphate (anhydrous, 0.5 hydrate, Hexahydrate, octahydrate, anhydrous water solubility: 14.5%), disodium hydrogen phosphate (anhydrous, dihydrate, heptahydrate, anhydrous water solubility: 20.6) %), Sodium dihydrogen phosphate (anhydrous, monohydrate, dihydrate, heptahydrate, anhydrous water solubility: 94.2%) and the like.

Among these water-soluble water-absorbing agents by chemical adsorption, anhydrous calcium lactate, anhydrous sodium sulfate, anhydrous aluminum potassium sulfate, and anhydrous magnesium sulfate are preferable, but water absorption rate and water absorption, shape at the time of hydrate, fluidity, crop phytotoxicity From the viewpoint of safety and cost, anhydrous magnesium sulfate is particularly preferable.
The amount of the water-absorbing agent that can be used in the present invention depends on the amount of water added during production, and is the amount that is stoichiometrically adsorbed with water from the viewpoint of simplicity of the production process and sprayability under high-temperature and high-humidity conditions. It is preferable to add to the above. The content in the finely divided fungicide composition and / or finely divided insecticide composition is usually 0.1 to 25% by weight, preferably 0.5 to 20% by weight.

<About other ingredients>
In addition to the above essential components, the finely divided fungicide composition and / or finely divided insecticide composition of the present invention includes, as necessary, a surfactant, a powdery carrier (white carbon, diatomaceous earth). , Glass powder, acid clay, urea, lactose, granulated sugar, etc.), fluidity improvers (isopropyl acid phosphate (PAP), etc.), pH adjusters (phosphoric acid, citric acid, etc.), etc. It can be added as long as the effect is not lost.

<About apparent specific gravity>
In the present invention, it is important to adjust the apparent specific gravity of the fine particle fungicide composition and / or the fine particle insecticide composition to 1.0 to 2.0. When the apparent specific gravity of the fine particle fungicide composition and / or the fine particle insecticide composition is less than 1.0, the fine particle fungicide composition and / or the fine particle insecticide composition itself is easily scattered by the influence of wind or the like. Become. On the other hand, when the apparent specific gravity exceeds 2.0, the volume of the fine particulate fungicide composition and / or the fine particulate insecticide composition becomes small, so that a spraying device such as a multi-hose equipped with a power spreader is used. When spraying from the above, the discharge time of the fine particulate fungicide composition and / or the fine particulate insecticide composition is shortened, resulting in problems such as difficulty in uniformly spreading the composition.
Therefore, it is essential to adjust the apparent specific gravity to 1.0 to 2.0 from the viewpoint of maintaining the dispersibility and sprayability of the fine particulate fungicide composition and / or fine particulate insecticide composition, and more preferably Is adjusted to 1.4 to 1.8.

The apparent specific gravity of the fine particulate fungicide composition and / or the fine particulate insecticide composition was measured by the following method.
(Apparent specific gravity measurement method)
A sieve with an aperture of 710 μm having an inner diameter of 200 mm and a depth of 45 mm is placed 20 cm above the upper part of a 100 mL metal cylindrical container having an inner diameter of 50 mm, and the fine fungicide composition and / or the fine insecticide composition are placed on the sieve. Fill in the metal cylindrical container while putting an appropriate amount and removing it with a brush. Then, using a glass slide, level the upper part of the metal cylindrical container, remove the excess fine particulate fungicide composition and / or fine particulate insecticide composition, and remove the contents in the metal cylindrical container. The weight (Ag) was measured, and the apparent specific gravity of the fine particulate fungicide composition and / or the fine particulate insecticide composition was determined from the following formula.

<Production Method of Fine Granular Bactericide Composition and / or Fine Granule Insecticide Composition>
The finely divided fungicide composition and / or the finely divided insecticide composition of the present invention can be produced by the following steps.

Then, after adding a water-soluble water-absorbing agent by chemical adsorption, mixing for about 10 minutes to 1 hour and performing a dehydration step, it is sieved as necessary, and a fine particle having an apparent specific gravity of 1.0 to 2.0 A pesticide composition was obtained.
The agrochemical active component may be a solid component that has been finely divided by Jet pulverization or wet pulverization in advance, and a liquid component may be adsorbed to an oil absorbent or the like.

  In the method for producing a finely divided agrochemical composition of the present invention, a water-absorbing mechanism by chemical adsorption is used, and a water-absorbing agent that does not solidify after water absorption or remains slightly consolidated is used. A crushing step is not required, and since it can be produced with only one mixer, it is a simple production method and is more advantageous than conventional production methods in terms of energy and cost. In addition, for solid binders, sufficient adhesive force is exerted by a simple mixing step with an agrochemical active ingredient, a finely divided carrier and water, and there is no step to make a solid binder into an aqueous solution or aqueous dispersion in advance. This is an abbreviated manufacturing method. Furthermore, the mixer that can be used in the present manufacturing method only needs to be capable of powder mixing and does not require functions such as variable temperature and pulverization. It can be used and is economical. Examples thereof include a Ladige mixer, a high speed mixer, a concrete mixer, a kneader, a ribbon mixer, and a pug mixer.

<Usage Mode of Fine Particulate Bactericide Composition and / or Fine Particulate Insecticide Composition>
The finely divided fungicide composition and / or finely divided insecticide composition produced as described above can be applied to crops using a multi-hose or a direct injection pipe equipped with a power spreader, or can be applied to an aircraft, manned helicopter, or radio control. It can be applied to crops from the air using a helicopter, etc., or can be applied to crops using a hand or a human power spreader. In addition, it can be used by treating the planting hole or stock of the crop, mixing the soil, treating the soil surface, or treating the seedling box.

  It should be noted that there is no problem even if two or more types of fine particulate fungicide composition and / or fine particulate insecticide composition obtained by the present technology are mixed in advance and then sprayed. Moreover, the application amount per 10 ares of the finely divided fungicide composition and / or the finely divided insecticide composition when sprayed to a paddy field using a multi-mouth hose or a direct injection tube is usually 0.5 to 5 kg. , Preferably 1 to 4 kg. The application amount per 10 are of the finely divided fungicide composition and / or the finely divided insecticide composition when used for horticultural use in crop planting holes and plant stocks, or when used for soil mixing treatment, Usually 0.5 to 50 kg, preferably 1 to 30 kg.

<Drift test (calculation of peel rate)>
A midget duster was installed in a greenhouse set at 35 ° C. and a humidity of 80% (installed so that the height of the discharge part from the ground is 1 m). Next, a factory fan was installed 2 m behind the midget duster discharge section, and the factory fan was operated so that the wind speed of the midget duster discharge section was 3 m / sec. In addition, a pole was set up at a position 10 m ahead of the midget duster discharge part, and a petri dish (diameter 9 cm) was installed at a position 1.5 m in height of the pole. 500 g of a sample composition (fine particulate pesticide composition produced in Examples 1 to 24 and Comparative Examples 1 to 48) previously stored for 1 week under conditions of 35 ° C. and 80% humidity is put into this apparatus and sprayed. Thereafter, the amount of sterilizing and / or insecticidal active ingredient (active ingredient) collected in the petri dish was measured. Moreover, the fine-grained agricultural chemical composition after spraying was collect | recovered, and the disinfection after spraying and / or insecticidal (active ingredient) content rate (%) were measured. And the peeling rate (%) was calculated from the following formula by comparison with the sterilization and / or insecticidal active ingredient content rate (%) before spraying. In addition, since the test is a double control for Examples 1 to 16 and Comparative Examples 1 to 32, and is a bactericidal insecticidal mixture for Examples 17 to 24 and Comparative Examples 33 to 48, 4 is used to measure each active ingredient. Conducted in continuous regime.
In addition, the amount of sterilizing or insecticidal active ingredient (active ingredient) is as follows.

Similarly, the scattering rate (%) of Examples 5 to 8 and Comparative Examples 9 to 16 is compared with the case of spraying the IBP (2%) powder of Comparative Example 50, Examples 9 to 12, 17 to 20 and comparative examples 17-24, 33-40 scattering rate (%), compared with the case of spraying the pyridafenthione (2%) powder of Comparative Example 51, and Examples 13-16, 21-24 and Comparative Examples The scattering rate (%) of 25 to 32 and 41 to 48 was calculated from the following formula by comparison with the case where the MEP (3%) powder of Comparative Example 52 was sprayed. In addition, since the test is a double control for Examples 1 to 16 and Comparative Examples 1 to 32, and is a bactericidal insecticidal mixture for Examples 17 to 24 and Comparative Examples 33 to 48, 4 is used to measure each active ingredient. Conducted in continuous regime.

<Explanation of the table>
(1) About drift
As apparent from Tables 1 to 6, the drift property evaluated from the peeling rate and the scattering rate was affected by the presence or absence of the solid binder and the apparent specific gravity. In Tables 1 to 6, Examples 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 using a solid binder and water and having an apparent specific gravity of 1.4 to 1.8. And 24, and Comparative Examples 2 to 4, 12, 19, 20, 28, 35 and 36, and polyvinyl alcohol, which is a solid binder, are used in an aqueous solution, and the apparent specific gravity is 1.4 to 1.8. In Example 8, both the peeling rate and the scattering rate were low, and the drift property was good. In addition, Examples 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23 using a solid binder and having an apparent specific gravity of 1.0 or more and less than 1.4, and comparison Comparative Examples 16, 24, and 32 using Examples 10, 18, 26, 27, 34 and 42 to 44 and polyvinyl alcohol as a solid binder in an aqueous solution and having an apparent specific gravity of 1.0 or more and less than 1.4. 40 and 48 showed a low peeling rate, but although the scattering rate was slightly high, it was at a level that was not problematic for practical use. On the other hand, although the solid binder is used, Comparative Examples 1, 9, 17, 25, 33 and 41 having an apparent specific gravity of less than 1.0 showed a high scattering rate although the peeling rate was low, The result was a concern about the drift of the particulate fungicide composition and / or the particulate insecticide composition itself. Further, although the apparent specific gravity is in the range of 1.0 to 2.0, Comparative Examples 7, 15, 23, 31, 39 and 47 which do not use a solid binder and a solid binder are used, but water is used. Comparative Examples 5, 13, 21, 29, 37, and 45, which do not use the above, show remarkably high values for both the peeling rate and the scattering rate, and Comparative Examples 6, 14, and 6 that use a liquid binder instead of the solid binder. 22, 30, 38, and 46 are practically problematic values, although both the peeling rate and the scattering rate are somewhat low, and all are drifts due to sterilization and / or peeling of the insecticidal active ingredient, and the particulate fungicide composition And / or drift of the particulate pesticide composition itself has been a concern.

(2) Dispersibility The dispersibility of the particulate fungicide composition and / or the particulate insecticide composition under the high-temperature and high-humidity conditions shown in Tables 1 to 6 is affected by the presence and type of the water-absorbing agent by chemical adsorption. It was. Examples 1 to 24 and Comparative Examples 1, 2, 5 to 7, 9, 10, 13 to 15, 17, 18, 21, 23, 25, 26, 29 to 31, 33, 34, 37 to 39, 41 , 42 and 45 to 47, the particulate disinfectant composition and / or the particulate insecticide composition is stored under a high temperature and high humidity condition and then sprayed under the same condition. Adhesiveness). In particular, Examples 1, 2, 5, 6, 9, 10, 13, 14, 17, 18, 21, and 22 using anhydrous magnesium sulfate as a water absorbing agent, and Comparative Examples 1, 5-7, 13, 21, 22, 29-31, 33, 37, 39 and 45-47 fine and / or fine pesticide compositions showed excellent results in terms of adhesion in the sprayer after spraying . On the other hand, Comparative Examples 4, 12, 20, 28, 36 and 44 which do not use a water absorbing agent by chemical adsorption, and Comparative Examples 3, 11, 19, 27, 35 and 43 which use a water absorbing agent by physical adsorption are in a high temperature and high humidity condition. Under storage, the fluidity deteriorated and the entire amount could not be discharged, and a large amount of adhesion was observed in the spreader, resulting in poor spraying. Further, for Comparative Examples 8, 16, 24, 32, 40 and 48 using hemihydrate gypsum as a water absorbing agent by chemical adsorption, a solidified substance considered to be derived from hemihydrate gypsum is produced in the preparation, and discharge unevenness and Clear adhesion in the spreader was observed and the spraying was poor.

(3) About blast control effect The blast control test results of Tables 1, 2, 5, and 6 were affected by the type of water-absorbing agent by chemical adsorption. Examples 1 to 8, 17 to 24, Comparative Examples 1, 5 to 7, 9, 13 to 15, 33, 37 to 39, 41, and 45 to 47, and physical adsorption using a water-soluble water-absorbing agent by chemical adsorption Comparative Examples 3, 11, 35 and 43 using the water-absorbing agent and Comparative Examples 4, 12, 36 and 44 not using the water-absorbing agent all had good control values. On the other hand, Comparative Examples 2 and 34 using anhydrous calcium oxalate having low water solubility (water solubility: 0.00067%) as a water-absorbing agent by chemical adsorption and anhydrous calcium monohydrogen phosphate (water solubility: 0.0225%) And Comparative Examples 10, 16, 40 and 48 using hemihydrate gypsum (calcium sulfate hemihydrate, water solubility: 0.3%) had a poor control value. became.

(4) Insecticidal effect on white-spotted planthopper The insecticide test results in Tables 3-6 were affected by the type of water-absorbing agent by chemical adsorption. Examples 9 to 24, comparative examples 17, 21 to 23, 25, 29 to 31, 33, 37 to 39, 41 and 45 to 47 using water-soluble water-absorbing agents by chemical adsorption, and water-absorbing agents by physical adsorption Comparative Examples 19, 27, 35 and 43 used, and Comparative Examples 20, 28, 36 and 44 which did not use a water-absorbing agent all had good mortality. On the other hand, Comparative Examples 18 and 34 using anhydrous calcium oxalate having low water solubility (water solubility: 0.00067%) as a water-absorbing agent by chemical adsorption, and anhydrous calcium monohydrogen phosphate (water solubility: 0.0225%) In Comparative Examples 26 and 42 using Hf and Comparative Examples 24, 32, 40 and 48 using hemihydrate gypsum (calcium sulfate hemihydrate, water solubility: 0.3%) It became.

  From the above, while using a solid binder, the water absorption mechanism is chemisorption and does not solidify after water absorption, or remains slightly consolidated, and the water solubility at 25 ° C. is 3% or more with respect to 100 g of water. The finely divided fungicide composition and / or the finely divided insecticide composition of Examples 1 to 24 using a water-soluble water-absorbing agent and having an apparent specific gravity of 1.0 to 2.0 are subjected to high temperature and high humidity conditions. Good results were obtained for any of the drifting properties, sprayability and bactericidal and / or insecticidal effects. On the other hand, Comparative Examples 1-48 have caused problems in any of driftability, sprayability, sterilization and / or insecticidal effect, and for driftability, Comparative Examples 7, 15, 23, which do not use a solid binder. 31, 39 and 47, and Comparative Examples 5, 13, 21, 29, 37 and 45 using a solid binder but no water, and Comparative Examples 6, 14, 22 using a liquid binder , 30, 38 and 46 are poor in terms of peeling rate and scattering rate, and Comparative Examples 1, 9, 17, 25, 33 and 41, whose apparent specific gravity is less than 1.0, are driftable in terms of scattering rate. Was bad. Moreover, as for the dispersibility under high-temperature and high-humidity conditions, Comparative Examples 4, 12, 20, 28, 36 and 44 in which no water-absorbing agent by chemical adsorption is used, and Comparative Examples 3, 11, in which a water-absorbing agent by physical adsorption is used. 19, 27, 35 and 43 and Comparative Examples 8, 16, 24, 32, 40 and 48 using hemihydrate gypsum were all poorly sprayed due to poor fluidity under high temperature and high humidity conditions. Comparative Examples 2, 8, 10, 16, 18, 24, 26, 32, 34, 40 using a water-absorbing agent with low water solubility, although the water-absorbing mechanism by chemical adsorption is used for the rice blast control effect and the white-spotted insecticide effect. , 42 and 48 were concerned that there would be a lack of effectiveness when uneven dispersion occurred.

  Therefore, while having the simplicity of the manufacturing method, the sterilization and / or the anti-peeling of the insecticidal active ingredient and the drift property as seen from the scattering of the fine particulate fungicide composition and / or the fine particulate insecticide composition, and the high temperature and high humidity conditions In order to maintain sprayability and develop stable biological effects, water is added to the powder mixture of the sterilizing and / or insecticidal active ingredient, the particulate carrier and the solid binder, and the water absorption mechanism is a water absorbing agent by chemical adsorption with water. In addition, the water-soluble water-absorbing agent having a water solubility at 25 ° C. of 3% or more with respect to 100 g of water is manufactured and added in order, and it is effective that the apparent specific gravity is 1.0 to 2.0 Further, it was found that it is more effective to use anhydrous magnesium sulfate as the water-soluble water-absorbing agent by the above chemical adsorption and adjust the apparent specific gravity to 1.4 to 1.8. It was.
