Description

Mixed granular agrochemical composition, granular agrochemical mixture and granular agrochemical mixture kit using the same

The present invention is a mixed granular pesticide composition in which two or more kinds of granular pesticide compositions having different compositions are mixed at least at the time of use, a granular pesticide mixture comprising a plurality of granular pesticide compositions, and on-site mixing. It relates to a granular pesticide mixture kit. Further, the present invention provides a method for evaluating the uniformity of individual granular pesticide compositions in the mixed granular pesticide composition and the granular pesticide mixture, a granular pesticide composition suitable for the mixed granular pesticide composition, and further its use. Also related.

Conventionally, various dosage forms such as powders, wettable powders, aqueous suspensions, and emulsions are known for agricultural chemical formulations, and one of them is a granule. Granules are a safe dosage form with little concern about adverse effects on the surrounding environment due to exposure to pesticide application workers due to powdering of agrochemical active ingredients and scattering when sprayed, and the dosage per unit area is around 10 ares A relatively small amount of 0.2-5kg, recently supported by the spread of power spreaders that can be applied to granule treatment, and because it is easy to apply agricultural chemicals to consumers in Japan (Japan) Widely accepted. In addition, since the degree of freedom in the formulation design is high and it is easy to control the dissolution characteristics of pesticidal active ingredients and other physicochemical characteristics as agrochemical preparations, dosage forms that are easy for suppliers to provide desired performance for consumers It is.

By the way, pests to be controlled in agriculture include plants (weeds), animals (pests), and microorganisms (phytopathogenic fungi and bacteria, etc.). There is no universal agrochemical active ingredient that does not adversely affect plants. In modern agriculture, weed active ingredients are used for weed control, insecticidal active ingredients are used for pest control, and bactericidal active ingredients are used for disease control. And farmland is managed. In addition, a single herbicidal active ingredient, a single insecticidal active ingredient or a single bactericidal active ingredient may not be effective in controlling all weeds, all pests or all microorganisms. Usually, there are high-sensitivity grass species, insect species or fungal species and low-sensitivity grass species, insect species or fungal species. Under such circumstances, in order to control all pests such as a wide variety of agricultural land, it is necessary to use a combination of a plurality of pesticidal active ingredients according to the target control target.

In order to meet these needs, several admixtures with a plurality of agrochemical active ingredients are commercially available in advance, but the number of combinations of agrochemical active ingredients required is enormous, and all of them are commodities with admixtures. It is virtually impossible to make it. In addition, each pesticidal active ingredient has its own physicochemical properties. For example, it can be mixed for adverse reasons such as acidic pesticidal active ingredient and basic pesticidal active ingredient. There are also combinations that are difficult to make. Furthermore, in the case of granules, the surface of the granular composition is coated with, for example, hydrophobic fine powder or resin in order to control the elution characteristics in a preferable pattern according to the characteristics of the agrochemical active ingredient contained in the granules. In some cases, elution control means such as forming a matrix of thermoplastic material in the granular composition may be provided, but such elution control means may be used to dissolve all agricultural chemical active ingredients contained in the granules. In order to affect the characteristics, it may not be possible to employ a mixture containing a plurality of pesticidal active ingredients having different preferable elution patterns.

Therefore, when applying a combination of agricultural chemical active ingredients for which a mixture is not commercially available to agricultural land or the like, it is necessary to prepare the agricultural chemical compositions containing the respective agricultural chemical active ingredients separately and perform the agricultural chemical application. Nonetheless, it is very labor and labor for agricultural workers to perform complicated pesticide application work by the number of the prepared agrochemical compositions. Therefore, a plurality of agrochemical compositions are mixed on site, and the mixture is mixed. By spraying, it is widely done to apply pesticides in one operation. When the above operation is performed on a granule, that is, a granular composition, a plurality of granules are mixed and processed simultaneously. In addition, in order to prepare a plurality of pesticidal active ingredients that are difficult to formulate in the form of granules and make a product packaged in a single package, granular pesticidal compositions containing individual pesticidal active ingredients are prepared separately A granular pesticide mixture in which these are mixed at a predetermined ratio is also known.

However, in order to uniformly apply a plurality of granular compositions having different compositions simultaneously, it is necessary that the granular compositions are sufficiently uniformly mixed. Since the granular material has a large particle size and cannot be micro-mixed like a powdery material, a bias due to classification or the like is likely to occur. When a mixture of granular agrochemical compositions that is not sufficiently homogeneously mixed is applied, the application is made unevenly, and even if it is the expected amount of drug to be applied to the entire application area, a part of the application area Insufficient pesticidal active ingredients may cause a lack of pharmacological effects, and at the same time may cause phytotoxicity due to excessive pesticidal active ingredients. In addition, in the production of granular pesticide mixtures, granular pesticide compositions containing individual pesticide active ingredients must be packed together in a sufficiently uniform mixture so that all the pesticide active ingredients are in the desired amount at the same time. Cannot be a pesticide combination. Therefore, many studies have been made to achieve sufficient uniform mixing of the granular agrochemical compositions, and various techniques have been proposed so far (Patent Documents 1-6).

JP 2000-86405 A Japanese Patent Laid-Open No. 2001-17847 JP 2001-206802 A JP 2004-352711 A JP 2007-176920 A Special table 2011-502138

However, whether or not the granular pesticide composition is actually sufficiently homogeneously mixed is determined by sampling the mixed granular pesticide composition and quantifying the individual pesticide active ingredients using an analyzer such as a liquid chromatograph. It is difficult to bring large-scale analyzers, laboratory tools, analytical reagents, etc. to agricultural application sites such as agricultural land, and those who are engaged in agricultural application work have mixed granular agricultural chemical compositions. The reality was that the only way to apply the pesticide was to believe that it was sufficiently uniform. In addition, in the production of granular agrochemical mixtures, the content of the pesticidal active ingredient in the granular agrochemical mixture immediately before packaging is confirmed by instrumental analysis. Is the granular agrochemical mixture currently being mixed already uniform? Whether the mixing process can be finished or not can be determined by looking at the composition being mixed. After all, based on experience, the mixing process is carried out for a sufficiently long time and the production line is waited. No other instrumental analysis was done to determine the end of mixing. Furthermore, the granular agrochemical composition has a phenomenon in which the grains gradually collapse in the mixing process, and if mixed for a long time, non-standard debris and powder due to friction increase, leading to loss in the manufacturing process. For this reason, it is desirable to stop the mixing step immediately when the mixing is uniformly performed, and a simple determination method for monitoring the mixing state has been desired.

Therefore, the present invention can easily determine the uniformity of the mixed granular pesticide composition without complicated instrumental analysis, and can be used with peace of mind by those engaged in pesticide application work. It aims at providing the granular agrochemical composition for obtaining an agrochemical composition etc.

As a result of intensive research aimed at solving the above problems, the present inventors have determined that two or more types of granular pesticide compositions constituting the mixed granular pesticide composition have a color difference of a certain level or more, so that two or more types of granular pesticide compositions in advance. When mixing granular pesticide composition to make mixed granular pesticide composition, mixing two or more kinds of granular pesticide composition by mixing on site to make mixed granular pesticide composition, that is, at least when using it, granular pesticide composition The mixed granular pesticide composition in a state where the products are mixed has been found to be able to visually confirm its uniformity, and has completed the present invention.

Since the mixed granular pesticide composition of the present invention can visually confirm uniformity, there is no need for troublesome instrumental analysis. Therefore, the mixed granular pesticidal composition of the present invention can be easily evaluated for uniformity and quality control.

Further, since the mixed granular pesticide composition of the present invention can be uniformly sprayed when it is applied, it is a matter of course that the desired medicinal effect is achieved, the granular pesticide constituting the mixed granular pesticide composition Since the mixed state of the compositions is obvious, it is possible to prevent an accident that the classified mixed granular pesticide composition is applied unevenly. Furthermore, by providing the agricultural worker with the uniformity of the mixed granular pesticide composition as visual information, it is possible to provide a mixed granular pesticide composition that can be used with a sense of security. In addition, in the mixing step, too much unnecessary long-time mixing aiming at uniform mixing can be abolished, and grain damage in the mixing step can be minimized.

The mixed granular pesticidal composition of the present invention is in a state where two or more types of granular pesticidal compositions having different compositions are mixed at least when used. This includes the case where two or more types of granular pesticide compositions are mixed in advance to form a mixed granular pesticide composition, or the case where two or more types of granular pesticide compositions are mixed to produce a mixed granular pesticide composition. .

The color difference ΔE ^* represented by the CIE 1976 color space (L ^* a ^* b ^* color system) of any two types of granular agrochemical compositions contained in the mixed granular agrochemical composition is 4.5 or more, preferably 5. 0 or more. This color difference ΔE ^* is obtained from the formula described in the examples described later for any two types of granular pesticide compositions by measuring the color coordinates in the CIE 1976 color space of each granular pesticide composition using a commercially available color difference meter. Alternatively, the color difference ΔE ^* of any two types of granular agrochemical compositions may be directly determined using a commercially available color difference meter. The technical common sense that associates the value of the color difference ΔE ^* with the human sense is “Science of Food Color” (Shin Saito, Koshobo, 1997) p. Although there is a table described in 185, the correspondence table correlates well with the degree of perception when two objects having a certain size, such as food, are adjacently compared or separated from each other. In the case of observing a mixed pesticidal granular composition in which a large number of fine pesticidal granular compositions each of which is less than that are observed, it is not appropriate. For example, when the color difference ΔE ^* between two objects is 0.8 to 1.6, the correspondence table is disclosed as “a level at which a slight color difference is felt in the adjacent comparison”. In a mixed pesticide granular composition composed of two types of pesticide granular compositions having different color differences, it is almost impossible for ordinary people to perceive the color difference between them, and in particular, the mixed pesticide granular composition is not in a stationary state. The perception becomes more difficult if the fluid is in the middle of mixing. In order for a human to perceive the color difference of the mixed pesticide granular composition, a color difference ΔE ^* of at least 4.5 is required in spite of the aforementioned technical common sense. When there is such a color difference ΔE ^*, it is possible to visually recognize whether or not both are uniformly mixed or classified in the mixed granular agrochemical composition. Here, the upper limit of the color difference ΔE ^* is not particularly limited. For example, even if the upper limit of the color difference ΔE ^* is 25 or less, 13 or less, and even 6.5 or less, the above-described visual recognition is sufficiently possible. Of course, there is no problem even if the color difference ΔE ^* exceeds 25. The CIE 1976 color space (L ^* a ^* b ^* color system) was developed by the International Commission on Illumination.

Each granular pesticide composition constituting the mixed granular pesticide composition of the present invention contains one or more pesticide active ingredients. The agrochemical active ingredient is not particularly limited, and for example, the following known herbicidal active ingredients, bactericidal active ingredients, insecticidal active ingredients and plant growth regulating active ingredients can be used.

Since the individual granular pesticide compositions constituting the mixed granular pesticide composition of the present invention are intended to be finally mixed to form a uniform mixed granular pesticide composition, the shape and size are difficult to classify each other. Needless to say, it is preferable to have a thickness and a mass. Here, in any two types of granular pesticide composition constituting the mixed granular pesticide composition, both shapes may be the same or different, but when they are the same shape, it is difficult to classify each other, The same shape is preferably cylindrical, substantially cylindrical, spherical or substantially spherical.

As a type of granular agrochemical composition, there is a large granular agrochemical composition suitable for water surface application, having a short diameter of 3 mm or more, a property of floating on the water surface, and a property of collapsing within 30 minutes after dropping in water. As is known, the large granular pesticide composition has a large volume per grain, and therefore does not move easily in the entire mixed granular pesticide composition. In order to make it uniform, careful mixing is required as compared with the case of obtaining a mixed granular pesticidal composition comprising a smaller granular pesticidal composition, and it is extremely difficult to determine the end point of such mixing. In addition, the large granular agrochemical composition that has the property of floating on the water surface and the property of disintegrating within 30 minutes after being dropped in water is likely to cause grain damage in the mixing process, and it is necessary to avoid mixing more than necessary. There is. The present invention is also suitable for a mixed granular agricultural chemical composition comprising such a large granular agricultural chemical composition.

Examples include granular agrochemical mixtures that are mixed and packaged in a single package.

When the mixed granular pesticide composition of the present invention is a granular pesticide mixture kit, an individual engaged in agricultural work immediately before pesticide application at an agricultural chemical application site such as agricultural land, before using the individual granular pesticide composition Can be obtained by mixing. When the mixing is sufficiently performed, the individual granular pesticide compositions constituting the mixed granular pesticide composition are randomly arranged in the entire mixed granular pesticide composition. In the mixed granular pesticide composition of the present invention, Since the color tone of the individual granular pesticide composition constituting it is different to the extent that a human can identify at a glance, the mixed granular pesticide composition as a whole exhibits a mosaic appearance. By this, those engaged in farming work can be confident that the mixed granular pesticide composition has been mixed uniformly, so that the mixing is finished without being worried about whether mixing is still insufficient, Application of the mixed granular agrochemical composition can be performed. If desired, the mixed granular pesticidal composition having a mosaic appearance can be photographed prior to that, and the photograph can be used as a work record in which the mixed granular pesticidal composition is uniformly made uniform.

To further deepen the conviction, for example, a predetermined amount of the mixed granular pesticide composition is randomly selected, and each granular pesticide composition is selected based on the difference in color, and then selected using a scale. The mass of the composition is measured, and the mass ratio of each of the actually measured granular pesticide compositions is compared with the mixed mass ratio of each granular pesticide composition in the entire mixed pesticide composition, or based on the difference in color tone. By measuring the number of particles of the granular pesticide composition of the above, by the method of comparing the particle number ratio of each measured granular pesticide composition and the mixed particle number ratio of each granular pesticide composition in the entire mixed granular pesticide composition, etc. Without using a large and expensive device that can analyze the active ingredients of agricultural chemicals, the mixing state of each granular agricultural chemical composition in the mixed granular agricultural chemical composition can be easily confirmed quantitatively at the site of agricultural chemical application. Stay And with their numbers, the mixed granular pesticidal composition can be reliably homogenized work record.

In addition, when the mixed granular pesticide composition of the present invention is a granular pesticide mixture, it can be obtained by mixing the individual pesticide compositions at a manufacturing site such as an agrochemical factory. In this case, the obtained mixed granular pesticide composition is packaged in a single package as a granular pesticide mixture, but it has already been described that it is difficult to determine the end of the mixing step in the production process of the granular pesticide mixture. As it is, the person who manufactures the granular pesticide mixture composed of the mixed granular pesticide composition of the present invention applies the various methods for confirming the mixed state of the mixed granular pesticide composition at the pesticide application site to apply the process control. It can be carried out easily, and the quality control of the granular pesticide mixture can be carried out by the same method.

Even after the mixed granular pesticide composition of the present invention is applied to agricultural land, non-agricultural land or seedling boxes that are not flooded, such application is uniformly performed for each granular pesticide composition in the mixed granular pesticide composition. Can be confirmed. That is, since the mixed granular pesticide composition is exposed on the surface of the soil or the like unless the cultivated land is flooded, those engaged in farm work applying the mixed granular pesticide composition of the present invention have a color tone. Based on the difference, the number of grains of each granular pesticide composition observed within a predetermined area is measured, and the ratio of the number of each measured granular pesticide composition, and each granular pesticide composition in the entire mixed granular pesticide composition It is possible to visually confirm that the individual granular pesticidal compositions in the mixed granular pesticidal composition are uniformly dispersed by comparing the mixed grain number ratios.

Moreover, the mixed granular pesticidal composition of the present invention can be applied to every scene in pesticide application. Specifically, the paddy rice seedling box is mixed with the soil, the seeds are sprinkled onto the surface of the soil, the hole-planting treatment at the time of transplanting, the rowing treatment, the side row treatment, the soil treatment, the foliage treatment, the plant base treatment, the water surface Application processing, other processing to cell trays and the like can be mentioned, but are not particularly limited. The application means is not particularly limited, and the same means as in general granules can be used. For example, direct granulation by hand, human-powered granulator, electric granulator, back-loaded power type Examples include dusting machines, traveling-type power granulators, tractor-equipped granulators, rice transplanter-equipped granulators, sideline application medicines, and air spraying means such as unmanned helicopters and drones. it can. The application amount when applying the mixed granular agrochemical composition of the present invention is not limited, but in the case of paddy field or upland, it is usually 0.1-20 kg per 10 ares, preferably 0.2- In the case of a paddy rice seedling box, it is usually 10-200 g, preferably 10-100 g per seedling box (usually 0.16 m ² ). Moreover, when applying to a cell tray, the application amount of about 30g per cell tray (128 holes) may be sufficient.

The mixed granular pesticide composition was observed, and the difficulty of the action of visually recognizing that each grain was uniformly mixed was evaluated.
Table 1 shows a correspondence table between the color difference ΔE ^* of each granular agrochemical composition with respect to the granular agrochemical composition of Reference Production Example 1 and the observation evaluation results. ΔE ^* was determined by the following formula.

[Test Example 2]
Put 50 granular agricultural chemical compositions of Production Example 1 into a 50 mL screw tube, then place 50 granular agricultural chemical compositions of Reference Production Example 1 into the same screw tube, and invert the screw tube once at a speed of 30 rpm. A mixed granular pesticide composition was prepared. Further, a mixed granular pesticide composition was prepared in the same manner for the granular pesticide composition of Production Example 2-5 instead of the granular pesticide composition of Production Example 1. In any case, since the mixing is not sufficient, it is strongly estimated that the state is inhomogeneous. This mixed granular pesticidal composition was observed to investigate whether or not each grain could be visually discriminated.
Table 2 shows the color difference ΔE ^* of each granular pesticide composition with respect to the granular pesticide composition of Reference Production Example 1, and a correspondence table of the survey results.

[Test Example 3]
50 granular agricultural chemical compositions of Production Example 1 and 50 granular agricultural chemical compositions of Reference Production Example 2 are placed in a glass cylinder having the same inner diameter of 5 cm and a height of 14 cm, and both ends are sealed with a mesh and homogenized by shaking vigorously. A mixed granular pesticide composition was prepared. Further, a mixed granular pesticide composition was prepared in the same manner for the granular pesticide composition of Production Example 2-5 instead of the granular pesticide composition of Production Example 1. The granular agrochemical composition of each production example constituting each mixed granular agrochemical composition and the granular agrochemical composition of Reference Production Example 2 have the same external shape except for the difference in color tone, but have a large specific gravity. . The cylinder containing the mixed granular pesticidal composition was made upright, and compressed air was blown from the lower bottom side to the upper bottom side of the cylinder for 30 seconds to flow the mixed granular pesticidal composition. Thereafter, the state of the mixed granular pesticide composition was visually observed. Furthermore, 10 granular agrochemical compositions were randomly taken from the upper layer of the cylinder, put into water, and the number of settled grains was measured. When the mixed granular pesticide composition is uniform, the theoretical number of settled grains is 5, and if classification is performed by the above-described classification by flow, the granular pesticide composition of each production example is used as a reference layer in the cylinder upper layer. Since the granular pesticidal composition of Example 2 is biased toward the lower layer, the actual number of settled grains decreases. The results are shown in Table 3.

In any experiment of Table 3, the number of grains settled in water was 0 or 1, and almost all 10 grains collected from the upper layer of the cylinder were the granular agrochemical compositions of the respective production examples. From this, in this test, the granular agrochemical composition of each production example and the granular agrochemical composition of Reference Production Example 2 were classified due to the difference in specific gravity. Even in the case of the mixture of the granular agrochemical composition of Production Example 1 and the granular agrochemical composition of Reference Production Example 2 that were found to be uniform in visual observation, classification actually occurred, so the results of visual observation in Table 3 Indicates that it is difficult to visually distinguish the classification due to the difference in color difference ΔE ^* between the granular pesticide compositions.
In addition, during the classification operation of this test, the mixed granular pesticide composition of Production Example 5 + Reference Production Example 2 was sprayed to a high position in the cylinder while the granular pesticide composition of Production Example 5 was sprayed to a reference production example. It was recognizable that the granular agrochemical composition of 2 remained in a relatively low flow. On the other hand, in the other mixed granular pesticide compositions, it was impossible to recognize the difference in color tone between the individual granular pesticide compositions in motion.

[Test Example 4]
Put 33 granular agricultural chemical compositions of Production Example 5 in a 50 mL screw tube, then put 33 granular agricultural chemical compositions of Production Example 6 in the same screw tube, and then add 33 granular agricultural chemical compositions of Reference Production Example 1 to the same The mixture is put into a screw tube, and the screw tube is inverted once at a speed of 30 rpm to prepare a mixed granular agrochemical composition. Since this operation is not sufficiently mixed, it is strongly estimated that the state is uneven. When the mixed granular pesticide composition is observed, the color tone of the grains present in the upper layer, the middle layer, and the lower layer are different from each other, and it can be instantaneously determined visually that each granular pesticide composition is biased.
Thereafter, the mixed granular pesticide composition is further inverted 29 times. When this mixed granular pesticide composition is observed, three types of granular pesticide compositions having different colors are mixed and mixed together, exhibiting a macroscopically uniform mosaic appearance, and each grain is uniformly mixed. Can be determined visually.
Table 3 shows the color difference ΔE ^* of any two types of granular pesticide compositions among the three types of granular pesticide compositions constituting the mixed granular pesticide composition.

The mixed granular agricultural chemical composition of the present invention can be used for the production of agricultural chemicals with high uniformity.
