Description

The present invention relates to a water-floating large-scale granular pesticide composition, and more specifically, for example, by spraying a small amount directly on the water surface of a paddy field or the like, a water-floating property capable of uniformly dispersing an agrochemical active ingredient. It relates to a large granular pesticide composition.

Conventionally, pesticide compositions used in paddy fields and the like are generally granules, powders, emulsions, wettable powders, and flowables. Of these pesticide compositions, granules and powders have been usually sprayed directly without diluting 1 to 4 kg per 10 a with water, but in recent years, labor saving of pesticide spraying has been demanded, which corresponds to this. In order to increase the content of agrochemical active ingredients in the agrochemical composition to reduce the amount applied as an agrochemical composition, or to spray by simply throwing it from the ridge without entering the paddy field, a labor-saving agrochemical composition that can be applied. Things are needed.

Various labor-saving agrochemical compositions have been studied to meet such demands, and the technology thereof has been disclosed. However, as a particularly effective one, Patent Document 1 contains an agrochemical active ingredient, and has a particle size. Disclosed is a large, water-floating granular pesticide composition having a particle size distribution of 80% or more for particles of 3 mm or more and a property of floating on the water surface and disintegrating on the water surface within 30 minutes. The pesticide composition has a high self-diffusive property, and by spraying a small amount of pesticide composition of about 250-500 g per 10a of paddy field directly, the pesticide active ingredient is evenly spread over the entire paddy field. Since it can be thrown and sprayed, it can be said to be an ideal agricultural chemical composition for labor-saving spraying.

The labor-saving sprayable pesticide composition as described in Patent Document 1 is a concentrated pesticide composition in which the content of the pesticide active ingredient in the pesticide composition is increased in order to reduce the spraying weight as the pesticide composition. Although a small amount of pesticide composition has been achieved by labor-saving treatment of the same amount of pesticide active ingredient as a classical pesticide composition, such pesticide composition has a small number of particles as the fate of a small amount of pesticide composition. , Uniform spraying is difficult. If the treatment amount of the pesticide active ingredient is biased at each point in the paddy field, the effect may be insufficient at the point where the pesticide active ingredient is insufficient, and the phytotoxicity may be caused at the point where the pesticide active ingredient is excessive. In order to overcome this point, the agrochemical composition of Patent Document 1 disintegrates while floating on the water surface when treated in a paddy field, so that the agrochemical active ingredient self-diffuses even when sprayed unevenly. A uniform design is given within the paddy field. That is, the agrochemical composition of Patent Document 1 is required to have a function of disintegrating on the water surface within a short time, specifically within 30 minutes, as a premise for exhibiting its performance.

Now, most of the currently known pesticidal active ingredients are organic compounds having hydrophobicity, although they are large or small. The agrochemical composition of Patent Document 1 contains a surfactant for imparting a function of disintegrating on the water surface. Generally, the presence of the organic compound particles causes the agrochemical composition to disintegrate due to the surfactant. Tends to hinder. More specifically, organic compound particles placed in water first try to dissolve in water in order to build a more disordered system, but the hydrophobicity of the organic compound itself makes the dissolution impossible or slow. In this case, in order to stabilize the thermodynamic state of self, the surfactant is trapped on the particle surface (if the surfactant is not present, the particles are aggregated and the area exposed to water is reduced). In addition, the hydrophobic group of the surfactant also adsorbs to the surface of the organic compound particles, if any, and behaves in a direction to minimize the interface between self and water. As a result, the surfactant occupied on the surface of the organic compound particles cannot participate in the disintegration of the pesticide composition, and cannot exhibit the disintegration function that was the intended purpose of blending.

Usually, the above problem can be avoided by incorporating a surfactant in an amount that is still adsorbed on the agricultural chemical active ingredient, but the higher the content of the agricultural chemical active ingredient in the agricultural chemical composition is set, the more It also increases the amount of surfactant required to disintegrate the composition. On the other hand, an agrochemical composition containing a large amount of a surfactant becomes a very viscous mass when the raw materials are kneaded, which makes it difficult to manufacture by extrusion granulation and easily absorbs moisture even if it is manufactured by force. There is a physical limitation on the amount of the surfactant blended, such as the spraying being an obstacle because it is an agrochemical composition. Therefore, the content of the agrochemical active ingredient in the agrochemical composition is naturally limited.

By the way, in the agrochemical composition, considering the dispersibility and suspension of the agrochemical active ingredient in water, and in order to exert the effect quickly, the agrochemical active ingredient is finely pulverized, and its volume average particle size is For example, it is usually used as fine particles having a particle size of less than 10 μm or less than 5 μm (for example, see Patent Documents 2-3). By doing so, after the pesticide composition is treated in a field such as a paddy field, the contact area between the pesticide active ingredient and water existing in the field is expanded, and the pesticide active ingredient can be eluted into water more quickly. It will be possible. The above-mentioned labor-saving sprayable pesticide composition did not leak to this example, and it was common knowledge in the field of pesticide formulation science to finely pulverize and mix pesticide active ingredients.

These pesticidal active ingredients can be used alone or in admixture of two or more. The total content of the pesticidal active ingredients is not particularly limited, but even a granular pesticidal composition containing a large amount of pesticidal active ingredients will disintegrate within 30 minutes on the water surface, that is, the disintegration property will be good. Specifically, it is preferably 8% by mass or more, more preferably 16% by mass or more, 24% by mass or more, 30% by mass or more, 36% by mass or more based on the total amount of the granular pesticide composition. Become. Of course, the disintegration property of the granular pesticide composition of the present invention is good even in the granular pesticide composition containing less than 8 parts by mass of the pesticide active ingredient. On the other hand, the upper limit of the total amount of the pesticidal active ingredient is not particularly limited, but considering the blending room of a surfactant and the like described later, up to about 80% by mass, preferably up to 75% by mass, and more preferably up to 70% by mass. It is good to say

The inventors of the present invention used the above-mentioned pesticide active ingredient that was not accidentally finely pulverized in the development study of the pesticide active ingredient containing a high concentration of the pesticide active ingredient. The improvement of disintegration property was confirmed. The present inventors have conducted further studies based on this finding, and finally, in a granular pesticide composition having a particle size distribution of 80% or more of particles having a particle size of 3 mm or more and a property of floating on the water surface, It was found that the use of an agrochemical active ingredient having a coarse particle size improves the disintegration property on the water surface.

The above-mentioned attempts that ignored conventional wisdom were motivations to finely pulverize pesticide active ingredients in the first place, and do not consider the aspect of rapidly exhibiting the effects of pesticide active ingredients. It was naturally feared that the delay of the expression of the effect and the decrease of the effect would occur in the granular pesticide composition which is not present, but even more surprisingly, the granular pesticide composition having the above-mentioned composition is the conventional, i.e., pesticide, in the drug efficacy test in the field. Except that the active ingredient was finely pulverized, it showed a medicinal effect equivalent to or higher than that of the granular pesticide composition having the same constitution. Moreover, in the test, the conventional granular pesticide composition took a long time to disintegrate on the water surface, and due to the effect of being blown by the wind during that time, the effect was insufficient on the windward side of the field, and a finding of chemical damage was found on the leeward side. On the other hand, a granular pesticide composition containing a coarse-grained pesticide active ingredient exhibited the desired diffusibility due to good disintegration on the water surface, and showed uniform and good medicinal effect over the entire field. ..

The reason why the disintegration property on the water surface of the granular pesticide composition is improved by using the agrochemical active ingredient having a coarse particle size and the reason why the delayed expression of the effect and the reduction of the effect are not observed in the granular pesticide composition are invented. Although they do not have a firm theory, one reasoning about the latter is that the granular pesticide composition according to the present invention has the property of disintegrating while floating on the water surface, and that it is a pesticide formulation having a dynamic element. It may be explained to the reason. As a property that is not found in classical pesticide compositions such as granules, water-floating granular pesticide compositions do not stay in place after treatment, but the pesticide active ingredient diffuses while moving by itself. It is considered that the self-concentration around the components is kept low, and the pesticidal active ingredient which is not finely pulverized may be eluted relatively quickly. The present invention is not bound by whether the above hypothesis is correct or not, but in any case, the correlation between the particle size of the pesticidal active ingredient and the rate of effect onset is generally supported by a vast amount of knowledge based on various past research reports. The above phenomenon contrary to the above is considered to be peculiar to the water surface floating granular pesticide composition as in the present invention.

In the present invention, the pesticidal active ingredient having a particle size of 10 μm or more, preferably 20 μm or more or 30 μm or more can be used. The upper limit of the particle size is, in consideration of the granulation property at the time of producing the granular pesticide composition and the need to make the content of the pesticide active ingredient in the granular pesticide composition uniform, etc. Those less than 1/10, preferably 300 μm or less, more preferably 100 μm or less are suitable for use. As a means for obtaining the agricultural chemical active ingredient having a particle size suitable for the present invention, a method known to those skilled in the art can be applied. That is, if the particle size of the pesticidal active ingredient is smaller than the above range, for example, by once dissolving in an organic solvent or the like and then recrystallized, a pesticidal active ingredient having a large particle size can be obtained, and When the particle size is larger than the above range, the pesticidal active ingredient having a desired particle size can be obtained by crushing using a mixer having a shearing force, an impact crusher or the like and then sieving.

Further, in the granular pesticide composition of the present invention, a surfactant is added in order to disintegrate the particles on the water surface and diffuse the pesticide active ingredient into water. As the surfactant that can be used, those generally used in agricultural chemical compositions can be used.

It is 1-10 mass %.

It is essential that the granular agricultural chemical composition of the present invention floats on the water surface. As a method of imparting water-floating property to the granular pesticide composition, for example, perlite made of pearlite or obsidian, foamed shirasu made of shirasu, phyllite obtained by firing in an aluminosilicate system, or microfoamed of sodium silicate or borax.

Examples thereof include copolymers, methyl methacrylate/acrylonitrile copolymers, acrylonitrile/methacrylonitrile/itaconic acid copolymers, and the like. The particle size of the hollow body is not particularly limited, but is usually 1-600 μm, preferably 3-300 μm, and more preferably 5-100 μm.

The blending amount of these hollow bodies is not particularly limited as long as the granular pesticide composition is an amount that obtains water surface buoyancy, but if it is blended more than necessary, it becomes brittle particles and crushes during storage or during transportation or use, In some cases, the amount of dust generated during manufacturing may increase, which is not desirable, so it is desirable to add the required minimum amount. Therefore, the upper limit of the content of the hollow body is generally up to about 30% by mass based on the total amount of the granular pesticide composition, preferably 15% by mass or less, and more preferably 5% by mass or less. When the hollow body is a plastic balloon, the granular pesticide composition can obtain the water surface floating property even with a compounding amount of 5% by mass or less. Further, the lower limit of the blending amount of the hollow body is 0.3% by mass, and preferably 0.5% by mass or more. When the blending ratio is less than 0.3% by mass, the granular agricultural chemical composition may not show water surface floating properties.

When these auxiliary agents are added, the total amount of the auxiliary agents is usually about 0.1-20% by mass, preferably 0.5-10% by mass, based on the total amount of the granular pesticide composition.

The granular agricultural chemical composition of the present invention is usually a granular composition containing the components described above and floating on the water surface. At that time, the disintegration time on the water surface is adjusted within 30 minutes, preferably within 20 minutes, and more preferably within 15 minutes. When the disintegration time exceeds 30 minutes, the granular pesticide composition is blown by the wind, which is not preferable. In order to further reduce the influence of blowing, when the granular pesticide composition floats on the water surface, the exposed portion on the water surface is 40% or less, preferably 20% or less of the entire granular pesticide composition, It is desirable to adjust the blending amount of each of the above components.

The production process of the granular pesticide composition of the present invention follows a known method. That is,
[A] mixing all raw materials constituting the granular pesticide composition to obtain a mixture;
[B] adding a predetermined amount of water to the mixture obtained in the step [a] and kneading the mixture;
[C] a step of discharging the kneaded product obtained in the step [b] from a screen having a pore size of 3 mm or more using an extrusion granulator to granulate the kneaded product.
[D] a step of drying the granulated product obtained in the step [c];
[E] a step of sieving the dried granulated product obtained in the step [d];
By passing through, the granular agricultural chemical composition of the present invention can be obtained.

In step [a], all raw materials constituting the granular agricultural chemical composition, including the agricultural chemical active ingredient, the surfactant, the hollow body and the solid carrier, are mixed. For mixing, a known mixer such as Nauta mixer or vertical mixer can be used. A mixture is obtained by mixing all the raw materials in the said mixer for a predetermined time. When a liquid pesticide active ingredient at room temperature is used, it is mixed with an oil absorbing material in advance, adsorbed and supported, and then mixed with other raw materials.

Next, water is added to the mixture obtained in step [a] and kneaded (step [b]). In kneading, a known kneader such as a kneader, ribbon mixer, vertical mixer can be used. The amount of water to be added is not particularly limited, but usually about 10-15% by mass in the mixture may be added as an outer percentage. A kneaded product is obtained by kneading this mixture in the above kneader for a predetermined time.

This kneaded product is discharged from a screen having a hole diameter of 3 mm or more, preferably 3-10 mm, more preferably 3-8 mm using an extrusion granulator and granulated (step [c]). In the granular pesticide composition of the present invention, the ratio of the short diameter to the long diameter of one grain is preferably 1-3, and more preferably 1-2. The minor axis is preferably 3-10 mm, more preferably 3-8 mm. Further, it is preferable to have an external shape composed of a curved surface, and by selecting such an external shape, the granular agricultural chemical composition can be used for transportation of the granular agricultural chemical composition or for spraying using a power sprayer or the like. It is possible to prevent generation of fine powder due to abrasion or collision between the compositions. As a means for imparting the external shape to the granular pesticide composition, for example, the granulated product obtained in the step [c] is cut into a desired length, put in a horizontal drum, and formed into a curved surface. It is possible to cite a method in which the drum is rotated until it becomes an external shape to give rolling motion to the granulated product. Specifically, it is preferable that at least the peripheral edges of the upper and lower surfaces of the columnar body be chamfered, and it is more preferable that the upper and lower surfaces be elliptical or spherical with curved surfaces such as hemispheres.

It is also effective to prevent the generation of the above-mentioned fine powder when the compression disintegration strength per grain of the granular pesticide composition is 0.1 kgf or more, preferably 0.3 kgf or more. The compressive collapse strength is a load value at the time when the particles collapse when a load is applied to one particle at a constant gravitational acceleration. The compressive disintegration strength per grain can be measured by using a commercially available load tester, a tensile compression tester, or the like.

Next, the obtained granulated product is dried (step [d]). The drying temperature for drying the granulated product is not particularly limited, but is about 40 to 95°C, and the residual water content is usually 0.3 to 3 mass based on the total amount of the granular pesticide composition. %, and preferably 0.3 to 1.5% by mass until the water content is dried. When the water content is in such a range, both pulverization and stickiness of the granular pesticide composition are suppressed. Although its specific gravity is not particularly limited, 0.3-1 is preferable, and 0.3-0.5 is more preferable, from the viewpoint of water surface floating property, easiness of packaging and securing of the number of particles.

Finally, the dried granulated product is sieved, and the dried granulated product having a desired particle size is selected to obtain the granular agricultural chemical composition of the present invention (step [e]). It is essential that the granular pesticide composition of the present invention contains more particles having a particle size of 3 mm or more, that is, particles having a particle size of 3 mm or more have a particle size distribution of 80% or more. It is more preferable that the particles of -10 mm be 80% or more, and particularly the particles of 3-8 mm be 80% or more. By making the formulation have the above-mentioned particle size distribution, it is possible to easily obtain a sprayed area of 5 to 50% of the total paddy area at a distance of 1 m or more from the ridge even when sprayed from the ridge. As a secondary effect of setting the particle size to 3 mm or more, misuse can be prevented because it can be easily distinguished from the rice seedling box-applied granules containing a large amount of particles having a particle size of about 0.8 mm. Can be mentioned. Even if misuse is noticed even after treating the rice seedling raising box, the formulation of the present invention floats on the surface of the water by putting the seedling raising box in water, and damage from misuse can be minimized.

As a preferable composition example of the granular pesticide composition of the present invention, for example, an active ingredient having a water surface application effect is contained as an ingredient in an amount of 8% by mass or more, and the particle diameter is 3-8 mm and the specific gravity is 0.3-0. 5, the ratio of the minor axis to the major axis is 1-2, the particle surface has an external shape of a curved surface, and it disintegrates within 20 minutes after being sprayed on the water surface.

The granular pesticidal composition of the present invention described above is not particularly limited as a method of spraying on the surface of water such as paddy fields, for example, a method of grasping and throwing the granular pesticidal composition with a hand wearing vinyl gloves, and introducing water to the paddy field. While using a single-point treatment at the water outlet, using a power sprayer to continuously discharge from the spray head and spray, or to open and close the shutter lever momentarily and intermittently discharge and spray, using a ladle And a method of throwing in a tubular container by shaking, a method of using a hand-operated granulator, and a method of spraying in a streak shape or a spot using a radio control helicopter. Alternatively, a predetermined amount of the obtained granular pesticide composition may be packaged in a water-soluble film such as polyvinyl alcohol and the whole package may be put into a paddy field in the form of a so-called jumbo agent.

Conventionally, in rice cultivation in paddy fields, in the case of so-called early cultivation in which the transplanting time is early, even if the water-floating granular pesticide composition is locally sprayed within a period of 1-2 weeks after transplanting, algae are generated in the paddy fields. Almost none, the diffusion of the pesticide active ingredient is good, and the desired effect is obtained. However, in so-called normal season cultivation where the transplanting period is after May, it is common that the water temperature rises and algae are generated at the appropriate time for spraying the pesticide, and this algae significantly inhibits the diffusion of the pesticide active ingredient. Therefore, the desired effects of pesticides are often not obtained. In particular, when a water-floating granular pesticide composition is locally sprayed on a paddy field where algae are blown by the wind, the effect of the pesticide is scarcely obtained in the part where the algae are blown. Further, even after a few weeks after transplantation, the growth of paddy rice progresses and the plant grows large, and then the water-floating pesticide composition is locally sprayed, the diffusion of the pesticide active ingredient is hindered. As described above, the labor-saving spraying composition that requires local spraying was a composition that is sprayed when the rice plant is small.

On the other hand, the granular pesticide composition of the present invention has good diffusion of the pesticide active ingredient in the paddy field where algae have been generated, or even in the paddy field where the rice strain has grown to some extent, and the desired pesticide effect can be obtained. It can be said that it is a water-floating granular pesticide composition, and by spraying this at a specific position in a paddy field and within a specific area, the pesticide active ingredient can be evenly distributed without almost obstructing labor saving at the time of spraying the pesticide. It is possible to spray. That is, the diffusible granular pesticide composition of the present invention having a particle size of 3 mm or more is 80% or more, floats on the water surface, and disintegrates on the water surface within 30 minutes is 1 m from the ridge of a paddy field under flooding. At the above distance, preferably at a distance of 2 m or more from the ridge, 5-50% of the total area of the paddy field, preferably 10-50%, is scattered and sprayed to uniformly spread the pesticide active ingredient in the paddy field. Can be sprayed.

The granular pesticide composition of the present invention can be applied to 50% or more of the total paddy field area without any problem, but it is meaningless for the purpose of labor-saving pesticide application and is applied to an area of 50% or less. Is desirable. Furthermore, as a matter of course, even in paddy fields where algae are not generated, paddy fields before transplantation, and paddy fields where the rice strain is small, the diffusion of the agrochemical active ingredient by the granular agrochemical composition of the present invention is good, and the desired agrochemical The effect can be obtained.
