Description

Water surface floating pesticide preparation
Technical Field
The present invention relates to a water-surface-floating agricultural chemical preparation having excellent spreadability and storage stability, which exhibits excellent floatability and spreadability in the treatment of paddy fields, particularly in the impoundment treatment (consolidated application) under shallow water conditions, and which maintains the performance even after long-term storage.
Background
As formulations of agricultural chemical preparations for rice, granules, powders, hydrating agents, troches, pack (pack) agents, suspensions, aqueous solvents, liquid agents, emulsions and the like are known. In recent years, for the purpose of saving labor in pesticide spraying, pesticide preparations (granules, suspensions for stock solution impounded water spraying, etc.) which can be sprayed only from the ridge without entering the paddy field have been developed and used. However, in such a pesticide preparation, the pesticide active ingredient is sprayed in a locally high concentration state, and therefore there are problems as follows: it takes a long time until the pesticidal active ingredient is uniformly diffused into the surface water; rice phytotoxicity or insufficient effects due to local uneven distribution of the pesticide active ingredient. As a means for solving these problems, it is required that the pesticidal active ingredient is rapidly and uniformly dispersed after the pesticidal formulation is put into a paddy field under water storage.
Various methods have been proposed to meet the above requirements, and the following patent documents are cited, for example.
In the pamphlet of international publication No. 2016-: (a) a step of kneading a mixture containing a part of an agricultural chemical active ingredient, a part of a surfactant, a part of a hollow body, a part of a solid carrier, and water; (b) a step of granulating the kneaded material obtained in the step (a) by using an extrusion granulator; (c) drying the granulated substance obtained in the step (b) to obtain granules; (d) a step of disintegrating the mitochondria obtained in the step (c); (e) a step of kneading a mixture containing the disintegrated product obtained in the step (d), the remaining part of the pesticidal active ingredient, the remaining part of the surfactant, the remaining part of the hollow body, the remaining part of the solid carrier, and water; (f) a step of discharging the kneaded product obtained in the step (e) through a screen having an aperture of 3mm or more by using an extrusion pelletizer and pelletizing the discharged product; and (g) drying the granulated product obtained in the step (f).

In the pamphlet of international publication 2005-29956 (patent document 6), there is proposed a uniformly diffusible granular pesticide preparation characterized by containing a non-disintegrating type pesticide granule which contains an acidic pesticide active ingredient, a cationic surfactant and a basic substance and does not disintegrate in water within 30 minutes, a surfactant and a floating ingredient, and the pesticide preparation has a particle size distribution in which the mass ratio of particles having a particle diameter of 3mm or more is 80 mass% or more and a property of floating on water surface immediately after being thrown to water surface, but disintegrates on water surface within 30 minutes.
Jp 2002-179507 a (patent document 7) proposes a uniformly diffusible granular agricultural chemical preparation which contains an agricultural chemical active ingredient, has a particle size distribution of 80% of a substance having a particle diameter of 3mm or more and a property of floating on water surface, disintegrates on water surface within 30 minutes, and is dispersedly sprayed over an area of 5 to 50% of the total area of a paddy field at a distance of 1m or more from the ridge of the paddy field under water storage.
In Japanese patent laid-open publication No. 2002-128605 (patent document 8), an agricultural chemical preparation for water surface application characterized by using an agricultural chemical active ingredient, a buoyant hollow body and a specific polyoxyalkylene alkyl ether phosphate or a salt thereof is proposed.
Japanese patent laid-open No. 2000-351701 (patent document 9) proposes a solid pesticide formulation floating on water, which comprises a water surface spreading agent comprising one or more of C2-C4 alkylene oxide adducts of C4-C10 alkyl alcohols and derivatives thereof, and a pesticide active ingredient.
Jp 2001-114603 a (patent document 10) proposes an agricultural chemical solid composition containing an agricultural chemical active ingredient and one or more water-soluble substances selected from inorganic salts, organic acids, saccharides, and urea having a particle diameter of 1/10 to 1/2 relative to the minor diameter of the agricultural chemical solid composition.
Jp 2000-319103 a (patent document 11) proposes a water-surface-floating granular pesticide preparation which is characterized by containing a pesticide active ingredient, a surfactant, a solid carrier, a water-surface-floatability imparting agent and water, and in which the content of water after molding is 0.3 to 6 parts by weight per 100 parts by weight of the water-surface-floating granular pesticide preparation, and a method for producing the same.
Jp 2000 a-319102 (patent document 12) proposes a water-surface-application type agricultural chemical preparation in which a water-surface-floating granular agricultural chemical containing an agricultural chemical active ingredient, a surfactant, a solid carrier and a water-surface-floatability imparting agent as components is packaged in a water-soluble film bag having a dissolution time of 1/5 or less of the disintegration time of the water-surface-floating granular agricultural chemical.
Jp 2000 a-302602 a (patent document 13) proposes a water-surface-floating granular pesticide preparation characterized by containing an active pesticide ingredient, a surfactant, a solid carrier, a water-surface-floating imparting agent, water, and, if necessary, other auxiliary agents, wherein (1) the weight of each granule is 0.03 to 0.3g, and the density of each granule is 0.4 or more and less than 1.0; (2) the ratio of the short diameter to the long diameter of one particle is 1-3, and the shape of the outer part is formed by a curved surface; (3) the time required for the particles floating on the water surface to disintegrate and disperse is 30 minutes or less.
Jp 11-310503 a (patent document 14) proposes a packaging agent for agricultural chemicals to be introduced into paddy fields, which is prepared by packaging a powdery or granular agricultural chemical preparation having a property of floating and spreading on water and containing no foaming agent with an open water-soluble film to prevent the solidification over time.
Either prior art technique improves diffusivity, but this is diffusivity under conditions that ensure water depth (volume). On the other hand, there are fields that can be kept only at shallow water depths (less than 3cm) for the reason of water leakage, natural lack of water, and the like. Under such conditions, when the buoyancy is small due to the close distance between the water surface and the soil, the preparation is stranded or buried in the soil at the time of spraying, and a large amount of the preparation settles at the spraying site, thereby possibly causing phytotoxicity at the spraying site or insufficient effect due to poor diffusion. In addition, shallow water depth is synonymous with a small amount of water, and the range in which an active ingredient can diffuse through the water surface or water is limited compared to the normal water depth (about 5 cm). In such a field, further excellent floatability and spreadability are required, and it is difficult to say that the conventional techniques are sufficient. Further, these properties are maintained even after long-term storage, and there is no mention in the prior art, and a preparation excellent in all of floatability, diffusibility and storage stability is required.

Effects of the invention
The water-surface-floating agricultural chemical preparation of the present invention has good floating properties and diffusibility, and therefore, even in a paddy field in which water is stored under shallow water conditions, the water surface movement of the preparation itself and the diffusibility after disintegration of the preparation are excellent, and the performance can be maintained even after long-term storage. Therefore, when spraying, spraying equipment such as a power sprayer or a granulator is not necessarily required, and spraying by hand may be used. Further, since spraying from one side of the ridge spreads, the use situation is not limited. Moreover, since quality deterioration is suppressed even after long-term storage, it can be stored in advance. Therefore, the water-surface-floating pesticide preparation of the present invention is a labor-saving preparation that reduces the physical, temporal, and economic burdens on the sprayer.

As the agricultural chemical active ingredient used in the present invention, any agricultural chemical active ingredient known in the art or developed in the future other than the above-described ones may be used as long as it achieves the same object as the present invention and is used as an agricultural chemical preparation floating on water.
One kind of the above-mentioned pesticidal active ingredient may be used, and two or more kinds may be used without any problem. The amount of the additive is usually 0.01 to 60% by weight, preferably 0.05 to 50% by weight, based on the formulation.
Floating carrier
The buoyant carrier used in the present invention has a hollow body to generate buoyancy, and therefore, not only floats on the water surface, but also has a function of a disintegration aid by generating minute gaps in the preparation, and contributes to floatability and diffusibility from the disintegrable surface. Examples of agents include: white sand hollow spheres (Shirasu balloons), Fly ash hollow spheres (Fly ash balloons), ceramic hollow spheres, synthetic resin hollow bodies, and the like having hollow bodies. Further, if the average particle size of these components is too large, the hardness of the preparation tends to become brittle, and therefore, those having an average particle size of 200 μm or less are preferable.
Particularly, in consideration of the balance among floatability, disintegratability and hardness of the preparation, it is preferable that the hollow spheres be white sand having an average particle diameter of 90 to 120 μm.
The amount of the buoyant carrier used in the present invention is not particularly limited as long as the formulation floats on the water surface, and is usually 2.0 to 80% by weight, preferably 5.0 to 70% by weight. Further, one or two or more of the above-mentioned substances may be used.
Na alkylnaphthalenesulfonate and Na dialkylsuccinate sulfonate (anionic surfactant)
Since the alkylnaphthalenesulfonic acids Na and dialkylsulfosuccinates Na used in the present invention are anionic surfactants having a balance between wettability and dispersibility, the inclusion of one or more of these anionic surfactants contributes to disintegration and dispersibility of the preparation, and the function of the present invention maintains this property even after long-term storage. Further, the effect of reducing the load during granulation, that is, the amount of water added during granulation may be smaller depending on the wetting ability during production.
The amount of the alkylnaphthalenesulfonate Na and dialkylsuccinate sulfonate Na that can be used in the present invention is 0.5 to 30% by weight, preferably 1 to 20% by weight, in the preparation.
Alkylnaphthalenesulfonic acid-formaldehyde condensate Na, naphthalenesulfonic acid-formaldehyde condensate Na, partially desulfonated lignosulfonic acid Na, and lignosulfonic acid Na (additional anionic surfactant)
The water-surface floating agricultural chemical preparation of the present invention further contains one or more compounds selected from the group consisting of alkylnaphthalenesulfonic acid-formaldehyde condensate Na, naphthalenesulfonic acid-formaldehyde condensate Na, and partially desulfonated lignosulfonic acid Na, thereby enhancing the diffusibility and storage stability.
Any of the components is a high-molecular sulfonic acid surfactant having a molecular weight of several thousands to several tens of thousands, and the use of the combination of the alkylnaphthalenesulfonic acid Na and the dialkylsulfosuccinate Na enhances the dispersibility, and maintains the effect even after long-term storage.
When the polyoxyalkylene alkyl ether phosphate salt and the water-soluble alkylene glycol described later are contained, the diffusibility and the storage stability function are enhanced by adding at least one selected from the group consisting of an alkylnaphthalenesulfonic acid-formaldehyde condensate Na, a naphthalenesulfonic acid-formaldehyde condensate Na, and a lignosulfonic acid Na.
The alkylnaphthalenesulfonic acid-formaldehyde condensate Na, naphthalenesulfonic acid-formaldehyde condensate Na, partially desulfonated lignosulfonic acid Na, and lignosulfonic acid Na that can be used in the present invention are added in an amount of 0.5 to 30% by weight, preferably 1 to 20% by weight, in the preparation.
Polyoxyalkylene alkyl ether phosphate ester salt (anionic surfactant)
The polyoxyalkylene alkyl ether phosphate ester salt represented by the following general formula (I) used in the present invention has excellent spreading power, wettability, dispersibility, and gelation ability by contact with water. When the preparation is brought into contact with water, the active ingredient is gelled in a form in which the active ingredient or the buoyant carrier is taken, whereby the active ingredient can be diffused to a further place in a state in which buoyancy is enhanced by the buoyant carrier. Further, since the gel exists around the pesticidal active ingredient at a high concentration when the gel is dissolved in water, the ingredient is efficiently adsorbed to the pesticidal active ingredient, and the pesticidal active ingredient is diffused to a further place after the gel state is released. Further, since gelation ability does not deteriorate, the effect of imparting a spreading force and a dispersing force to the preparation and the floating assist are sustained even after long-term storage.

[ wherein R represents a linear or branched alkyl group having 8 to 10 carbon atoms, A represents an alkylene group having 2 to 4 carbon atoms, n represents an integer of 1 to 20, p and q represent p + q ═ 3, p ═ 1 or 2, and M represents a hydrogen atom, an alkali metal atom, an ammonium group or an organic ammonium group.

In the present invention, examples of the alkylene group represented by a in the phosphate ester salt represented by the general formula (I) include: an ethylene group having 2 carbon atoms, a propylene group having 3 carbon atoms, and a butylene group having 4 carbon atoms.
In order to exert the expansibility and the gelling ability in the present invention, the alkylene group preferably contains an ethylene group having 2 carbon atoms. The alkylene group represented by a may be only an ethylene group having 2 carbon atoms, or may include an ethylene group having 2 carbon atoms and a propylene group having 3 carbon atoms, an ethylene group having 2 carbon atoms and a butylene group having 4 carbon atoms, or an ethylene group having 2 carbon atoms and a propylene group having 3 carbon atoms and a butylene group having 4 carbon atoms.
In the present invention, in order to balance the solubility in water and the spreading force on water surface, the alkyl group represented by R in the phosphate ester salt represented by the general formula (I) needs to have a branched or branched structure having 8 to 10 carbon atoms, and examples of the alkyl group include: n-octyl, n-decyl, isodecyl, and 2-ethylhexyl groups, and the like.
In the present invention, the phosphate ester salt represented by the general formula (I) is not particularly limited as long as the cation (M in the formula) paired with a phosphate ion is within a range not to lose the function of the present invention, and examples of the atom represented by M include: a hydrogen atom; examples of the substituent of the alkali metal atom such as a lithium atom, a sodium atom, or a potassium atom include: an organic ammonium group such as an ammonium group, a methyl ammonium group or a dimethyl ammonium group.

Water-soluble alkylene glycol
In order to exert the function of the polyoxyalkylene alkyl ether phosphate described above, the water-soluble alkylene glycol used in the present invention is essential. When the water-soluble alkylene glycol is used in combination with a polyoxyalkylene alkyl ether, the water dissolution time of a gel produced when the water-soluble alkylene glycol is contacted with water is adjusted. Thus, not only the spreading power and the dispersing power of the polyoxyalkylene alkyl ether phosphate are maximized, but also the effect of imparting a floating assist effect to the preparation can be obtained by retaining the floating carrier by the gel.

(B.) Properties of the preparation
In order to exhibit good floatability and spreadability and excellent storage stability, the water-surface-floating agricultural chemical preparation of the present invention requires physical properties of the agricultural chemical preparation, such as "ratio of length to diameter of bottom surface of particle", "particle size", "number of particles per 1 g" described below, in addition to the ingredients of the preparation.
[ ratio of major axis to minor axis of bottom surface of particle ]
In the water-surface-floating agricultural chemical preparation of the present invention, the bottom surface of the particle is a surface derived from the mesh holes at the time of granulation, and the major axis and the minor axis on the bottom surface are the major axis which is the maximum diameter when a straight line (diameter) passing through the center of the bottom surface is drawn, and the minor axis which is the minimum diameter when a straight line (diameter) passing through the center of the bottom surface is drawn.
Therefore, the major axis/minor axis ratio of the bottom surface of the particle is a value obtained by cutting the bottom surface of the preparation with a cutter so that the bottom surface becomes a cross section, measuring the maximum diameter (major axis) and the minimum diameter (minor axis) of the cross section with a microscope, and calculating the ratio of the major axis to the minor axis as the average value of 10 granules of the preparation.
In the water-surface-floating pesticide preparation of the present invention, adjustment of the major axis/minor axis ratio on the bottom surface of the particles contributes to the floatability, diffusibility, and storage stability (the arrival distance and diffusion distance of the preparation after long-term storage) of the preparation. In order to provide the effect of improving the floatability and the diffusibility, it is necessary to adjust the ratio of the major axis to the minor axis to be in the range of 1.1 to 1.4. The major axis/minor axis ratio is a parameter indicating the shape of the preparation, and the shape of the bottom surface is a perfect circle at 1.0 (minimum value), and the larger the value, the closer the particle is to a flat shape. When the ratio of the major axis to the minor axis is 1.0, the migration of the preparation on the water surface is slow and the diffusibility is reduced, and when the ratio of the major axis to the minor axis exceeds 1.4, the migration on the water surface becomes fast but the dispersion is rapidly disintegrated and dispersed, and as a result, the diffusion distance of the active ingredient is shortened.
In the case of containing a polyoxyalkylene alkyl ether phosphate and propylene glycol, the disintegration time of the preparation in water increases due to gel formation occurring when the preparation is contacted with water, and therefore the upper limit of the ratio of the major axis to the minor axis can be 1.6. In addition, regarding the arrival distance and diffusion distance of the preparation after long-term storage, when the major axis/minor axis ratio is 1.1 or more, the quality degradation after long-term storage is suppressed. This is presumably because the surface area of the preparation in contact with the water surface increases with an increase in the ratio of the major axis to the minor axis, and the preparation is easily affected by the buoyancy of water, or the release rate of the surfactant on the water surface increases, whereby the efficiency of disintegration and dispersion on the water surface improves.
As a method for adjusting the major axis/minor axis ratio, there is a method in which the extrusion pore diameter is adjusted during granulation in the extrusion granulation step, and then the granulated material before drying is rotated using a drum-type granulator or a machine for rotating particles such as a ball granulator (Malmerizer) in the granulation step, and the control of the major axis/minor axis ratio is performed by controlling the centrifugal force.
In the granulated material before drying, the binder contains moisture, and is softened in a swollen state, and the granulated material has a large granulated particle diameter (extrusion pore diameter), and is also affected by its own weight. Therefore, when the rotational motion is applied, centrifugal force and self-weight act, and the cross section of the granulated substance is flattened (long diameter and short diameter are generated).
Particle size
In the water-surface-floating pesticide preparation of the present invention, the particle size is calculated according to the following formula (1) based on the weight of the preparation remaining on a 1.70mm mesh screen when 100g of the preparation is screened using test screens having 2.80mm and 1.70mm mesh openings.
[ numerical formula 1]
Figure BDA0002931064730000171
In the water-surface-floating pesticide preparation of the present invention, the particle size adjustment contributes to the floating and diffusing properties of the preparation. From the viewpoint of balance between floatability and diffusibility, it is necessary that the particle size is 80 wt% or more, preferably 90 wt% or more, within the range of 2.80mm to 1.70 mm. In terms of particle size, particles smaller than this particle size range tend to sink easily because of less buoyant carriers and less buoyancy, and particles of larger particle size tend to move slowly on the water surface because of the larger weight of each particle, resulting in poor diffusibility.
As a method for adjusting the particle size, there is a method in which the extrusion pore size is adjusted at the time of granulation in the extrusion granulation step, and then the particle size is controlled by appropriately adjusting the length of the particles of the granulated substance before drying in the granule sizing step. The granulator used for adjusting the particle size is not particularly limited, and a disintegrating granulator such as a rotary granulator like a drum granulator or a ball granulator, a pin mill (pin mill), an oscillator, a round mill (Roundel mill), or a non-mesh type granulator (ネビュライザー) can be used. From the viewpoint of economy and labor saving in production, a rotary granulator such as a drum granulator capable of simultaneously adjusting the ratio of the major axis to the minor axis of the bottom surface of the granules is preferable.
Number of grains per 1g
In the water-surface-floating pesticide preparation of the present invention, the number of particles of 5.0g of the preparation measured by a particle number measuring machine per 1g of the preparation is expressed as a value of one fifth of the measured value (rounded up to the decimal point).
In the water-surface-floating agricultural chemical preparation of the present invention, the adjustment of the number of particles per 1g contributes to the floating and spreading properties of the preparation. From the viewpoint of balance between floatability and diffusibility, the number of particles per 1g is required to be 50 to 150. For the same reason as the above particle size, particles having a particle number of more than 150 per 1g are likely to sink due to small particles and small buoyancy, and particles having a particle weight of less than 50 per particle are slow to move on the water surface due to large weight, resulting in poor diffusibility.
In the case where the polyoxyalkylene alkyl ether phosphate salt and propylene glycol are contained, even the particles having small buoyancy can be diffused to a further place by enhancing the diffusibility, and therefore the upper limit of the number of particles per 1g can be 200.
As a method for adjusting the number of particles per 1g, there is a method of controlling the number of particles per 1g by crushing the granulated substance before drying in the granulating step. The granulator used for adjusting the number of particles is not particularly limited, and a rotary granulator such as a drum granulator or a ball granulator, a pin mill, an oscillator, a circular mill, or a disintegrating granulator such as a mesh-less granulator may be used. From the viewpoint of economy and labor saving in production, a rotary granulator such as a drum granulator capable of simultaneously adjusting the major axis/minor axis ratio and the particle size of the bottom surface of the particles is preferable.
Method for producing pesticide preparation floating on water surface
The water-surface-floating pesticide preparation of the present invention is produced by an extrusion granulation method, and is advantageous from the viewpoint of economy and production efficiency.
As the production process, an agricultural chemical active ingredient, a floating carrier, one or more selected from alkylnaphthalenesulfonic acid Na and dialkylsuccinate sulfonic acid Na, if necessary, a polyoxyalkylene alkyl ether phosphate, one or more selected from alkylnaphthalenesulfonic acid-formaldehyde condensate Na, naphthalenesulfonic acid-formaldehyde condensate Na, and partially desulfonated lignosulfonic acid Na and lignosulfonic acid Na, if necessary, and various adjuvants are added and uniformly mixed using a slurry (joint) stirrer, a hammer mill, a rodige (Loedige) stirrer, a Ribbon Mixer (Ribbon Mixer), or the like. To the mixture, water is added, and kneading is performed using a double arm kneader, a ribbon mixer, or the like. When the agricultural chemical active ingredient is wet-pulverized and added to the slurry for the reason of mixing accuracy or the like, water is also added during kneading.
In the granulating step and the size-adjusting step after the kneading step, the physical properties of the water-surface-floating pesticide preparation of the present invention are adjusted. In the granule sizing step, the ratio of the major axis to the minor axis of the bottom surface of the granule, the particle size, and the number of granules may be adjusted together, or the particle size and the number of granules may be adjusted after the ratio of the major axis to the minor axis of the bottom surface of the granule is adjusted. From the viewpoint of omitting the number of steps and improving the economy in production, it is preferable to adjust them together.
In the granulating and finishing step, the mixture is first granulated using an extrusion granulator such as a basket (basket) granulator or a screw granulator. In order to adjust the physical properties of the water-surface-floating pesticide preparation of the present invention, the extrusion pore diameter during granulation is preferably 2.8 to 3.0 mm. When the extrusion pore diameter is the same as the above, the water-surface-floating agricultural chemical preparation of the present invention can be granulated by granulating the obtained granules with a machine such as a drum granulator or a ball granulator that applies a centrifugal force to the granules, so that the ratio of the major axis to the minor axis on the bottom surface is 1.1 to 1.4, the particle size is 80 wt% or more in the range of 2.80mm to 1.70mm, and the number of granules per 1g is 50 to 150. After the granulation, the water-surface-floating pesticide preparation used in the present invention is obtained by drying the granules using a fluidized bed dryer, a bed dryer, or the like, followed by screening.
In the case where an agricultural chemical active ingredient intended to promote dissolution is used in combination, a covering step may be added within a range in which the effect of the present invention is not lost.

As the spraying method, there can be mentioned: hand spills, puts into containers such as cup and sprays, the machinery that utilizes power spraying machine to carry out sprays, has used the aerial of radio remote control helicopter, unmanned aerial vehicle etc. to spray, sprays in the mouth of a river of the water that flows into the paddy field and sprays etc.. If consideration is given to the aspect of avoiding exposure of the sprayer to the formulation, a spraying method that does not directly touch the formulation is preferable. The amount of the surfactant to be applied is usually 50 to 500g, preferably 75 to 300g, based on 10 a.

(1) Diffusivity test 1 (determination of diffusivity under shallow water depth and downwind conditions)
The sediment is influenced by the floating carrier, the alkylnaphthalene sulfonic acid Na or dialkylsuccinate sulfonic acid Na, the particle size, the ratio of the major axis to the minor axis of the bottom surface of the particle, and the number of particles per 1 g. In tables 2-1 to 2-5, the precipitates, the preparation arrival distances, and the diffusion distances of examples 1 to 85 satisfying any requirements are within the range in which there is no practical problem. On the other hand, as a result of the comparative examples in which any of the components was not included or replaced with a substitute, there was a practical problem with precipitates at the time of production or after 90 days of storage at 40 ℃.
In any of the examples, the formulations to which any of the alkylnaphthalenesulfonic acid-formaldehyde condensate Na, naphthalenesulfonic acid-formaldehyde condensate Na, or partially desulfonated lignosulfonic acid Na was further added suppressed in performance (sediment, formulation arrival distance, diffusion distance) after 90 days at 40 ℃. In addition, the preparation containing carboxymethyl cellulose Na as a binder was improved in sediment and diffusion distance as compared with the examples using other binders. The overall diffusibility was most excellent in examples 16, 17, 33, 34, 50, 51, 67, 68, 84, 85 including the initial preparation and 90 days after 40 ℃, and in the above examples, the buoyant carrier was white sand hollow spheres having an average particle diameter of 90 to 120 μm, and contained either alkylnaphthalenesulfonic acid Na or dialkylsulfosuccinic acid Na, further contained either alkylnaphthalenesulfonic acid-formaldehyde condensate Na, naphthalenesulfonic acid-formaldehyde condensate Na, or partially desulfonated lignosulfonic acid Na, and contained carboxymethylcellulose Na as a binder, and the particle size was 90 wt% or more in the range of 2.80mm to 1.70mm, the major axis/minor axis ratio of the bottom surface of the particle was 1.1 to 1.4, and the number of particles per 1g was 50 to 150.
As a result, it has been found that it is effective to set the active ingredient of the agricultural chemical, the floating carrier, Na alkylnaphthalenesulfonate or Na dialkylsulfosuccinate to a particle size of 80 wt% or more in the range of 2.80 to 1.70mm, the major axis/minor axis ratio of the bottom surface of the particle of 1.1 to 1.4, and the number of particles per 1g of 50 to 150 so that the diffusibility of the deposit, the arrival distance of the preparation, and the diffusion distance can be sufficiently exhibited both immediately after the preparation and after the long-term storage, it is more effective to set the particle size to be 90 wt% or more in the range of 2.80mm to 1.70mm, the floating carrier to be white sand hollow spheres having an average particle size of 90 to 120 μm, the binder to contain one of alkyl naphthalene sulfonic acid formaldehyde condensate Na, naphthalene sulfonic acid formaldehyde condensate Na and partially desulfonated lignin sulfonic acid Na.
(2) Diffusibility test 2 (confirmation of diffusibility under shallow water depth and no wind condition)
Examples 86 to 102, 105 to 121, 124 to 140, and 143 to 159 each containing a polyoxyalkylene alkyl ether phosphate and a water-soluble alkylene glycol such as propylene glycol showed more excellent deposition, preparation arrival distance, and diffusion distance at the time of production and after 150 days at 40 ℃, and further improved diffusibility, as compared with examples 16, 17, 33, 34, 50, 51, 67, 68, 84, 85, 103, 104, 122, 123, 141, 142, 160, and 161 each containing no such component (tables 2-1 to 2-9).
In the examples containing the polyoxyalkylene alkyl ether phosphate and propylene glycol, in particular, the formulations using white sand hollow spheres having a particle size of 90% by weight or more in the range of 2.80mm to 1.70mm and an average particle diameter of 90 to 120 μm as a floating carrier, the formulations to which any of alkylnaphthalenesulfonic acid formaldehyde condensate Na, naphthalenesulfonic acid formaldehyde condensate Na, or lignosulfonic acid Na is added, and the formulations containing carboxymethylcellulose Na or polyvinyl alcohol as a binder are more excellent in the sediment after 150 days of storage at the time of production or at 40 ℃. Examples 102, 121, 140 and 159 are the most excellent in overall diffusibility including just after production and after 150 days at 40 ℃, and in the above examples, the buoyant carrier is a white sand hollow sphere having an average particle diameter of 90 to 120 μm, and contains Na alkylnaphthalenesulfonate or Na dialkylsuccinate sulfonate, further contains one of Na alkylnaphthalenesulfonate-formaldehyde condensate, Na naphthalenesulfonate-formaldehyde condensate and Na lignosulfonate, contains Na carboxymethylcellulose or polyvinyl alcohol as a binder, has a particle size of 2.80 to 1.70mm of 90 wt% or more, and has a major axis/minor axis ratio of 1.1 to 1.6 on the bottom surface of the particle.
As a result, it has been found that, in order to allow an agricultural chemical preparation floating on water to more efficiently exhibit diffusibility in which sediment, the arrival distance of the preparation, and the diffusion distance are integrated, both immediately after preparation and after long-term storage, it is effective to set the agricultural chemical active ingredient, the floating carrier, the polyoxyalkylene alkyl ether phosphate, and Na alkyl naphthalene sulfonate or Na dialkyl succinate sulfonate to have a particle size of 80 wt% or more in the range of 2.80mm to 1.70mm, a major axis/minor axis ratio of the bottom surface of the particle of 1.1 to 1.6, and a number of particles per 1g of 50 to 200, it is more effective to set the particle size to be 90% by weight or more in the range of 2.80mm to 1.70mm, and the floating carrier to be a hollow sphere of white sand having an average particle size of 90 to 120 μm, to contain one of alkyl naphthalene sulfonic acid formaldehyde condensate Na, and lignin sulfonic acid Na, and to contain carboxymethyl cellulose Na or polyvinyl alcohol as a binder.
