Description

INDUSTRIAL APPLICABILITY The present invention exhibits excellent buoyancy and diffusibility in the treatment of paddy fields, especially in flooding treatment under shallow water conditions, and maintains its performance even after long-term storage. It relates to a surface-floating pesticide formulation.

Granules, powders, wettable powders, tablets, packs, flowable formulations, aqueous solutions, liquid formulations, emulsions and the like are known as formulations of pesticide formulations for paddy rice. In recent years, agricultural chemical formulations (jumbo formulations, undiluted solution flooded spraying flowable formulations, etc.) that can be sprayed only from ridges without entering paddy fields have been developed and used to save labor in agricultural chemical spraying. However, since such a pesticide formulation sprays the pesticidal active ingredient locally in a highly concentrated state, it takes a long time for the pesticidal active ingredient to diffuse evenly in the surface water. There is a problem of rice phytotoxicity or lack of effectiveness due to the uneven distribution of rice. As a means of solving these problems, it is required that the active ingredient of the agricultural chemical be rapidly and uniformly dispersed after the agricultural chemical formulation is put into the flooded paddy field.

Various methods have been proposed to meet the above requirements, and examples thereof include the following patent documents.

All of the prior arts have improved diffusivity, but this is diffusivity under the condition that water depth (water volume) is guaranteed. On the other hand, there are fields where only a shallow water depth (less than 3 cm) can be maintained due to water leakage, natural water loss, and the like. Under such conditions, the distance between the water surface and the soil is close, so if the buoyancy is small, the formulation will run aground or be buried in the soil during spraying, and a large amount of sediment will settle at the spraying point, resulting in chemical damage or poor diffusion at the spraying point. It may cause ineffectiveness. A shallow water depth is synonymous with a small amount of water, and in formulations in which the active ingredient diffuses through the water surface or water, the diffusible range is limited compared to normal water depths (about 5 cm). In such fields, better buoyancy and diffusion are required, and it is difficult to say that the prior art is sufficient. In addition, the prior art does not mention maintaining these properties even after long-term storage, and there is a demand for a formulation that is excellent in all of floating property, diffusibility, and storage stability.

<B. Regarding the physical properties of the formulation>
In the water-floatable pesticide formulation of the present invention, in order to exhibit good buoyancy and diffusibility and to exhibit an excellent effect on storage stability, not only the formulation components but also the following <<long diameter of the bottom of the grain / The physical properties of agricultural chemical formulations such as minor axis ratio, particle size, and number of particles per gram are required.

《Ratio of major diameter/minor diameter of the bottom surface of the grain》
In the water-floating pesticide formulation of the present invention, the bottom surface of the grain refers to the surface derived from the screen holes during granulation, and the major and minor diameters of the bottom surface are obtained by drawing a straight line (diameter) passing through the center of the bottom surface. Let the maximum diameter be the major axis and the minimum diameter be the minor axis.

Therefore, the major diameter/minor diameter ratio of the base of the grain is obtained by cutting the bottom of the formulation with a cutter so that it becomes a cross section, then measuring the maximum diameter (major diameter) and minimum diameter (minor diameter) of the cross section with a microscope. , and refers to a value obtained by calculating the ratio of the major axis to the minor axis as the average value of 10 tablets.

In the water-floating pesticide formulation of the present invention, adjusting the major axis/minor axis ratio at the bottom surface of the grain affects the buoyancy, diffusibility, and storage stability of the formulation (formulation reaching distance after long-term storage, diffusion distance). contribute. It is essential to adjust the major axis/minor axis ratio to the range of 1.1 to 1.4 in order to impart the effect of improving the floating property and the diffusibility. The major axis/minor axis ratio is a parameter that expresses the shape of the preparation. At 1.0 (minimum value), the shape of the bottom surface is a perfect circle, and as the value increases, the shape of the grain approaches a flat shape. When the major axis/minor axis ratio is 1.0, the movement of the formulation on the water surface is slow, resulting in a decrease in diffusibility. As a result, the diffusion distance of the active ingredient is shortened.
When polyoxyalkylene alkyl ether phosphate salt and propylene glycol are contained, the disintegration time of the formulation in water increases due to the gel generated when it comes into contact with water. Up to 6 is possible. In addition, with respect to the formulation reaching distance and diffusion distance after long-term storage, deterioration in quality after long-term storage is suppressed when the ratio of major axis/minor axis is 1.1 or more. These factors are due to the fact that as the length/breadth ratio increases, the area of the formulation in contact with the water surface increases, making it more susceptible to the buoyancy of water, or the release rate of the surfactant on the water surface increases. It is presumed that this is because the efficiency of disintegration on the water surface is improved.

As a method for adjusting the major diameter/minor diameter ratio, in the extrusion granulation process, the extrusion hole diameter is adjusted at the time of granulation, and then in the granulation process, a machine such as a drum type granulator or Marumerizer that rotates the granules. is used to rotate the granulated material before drying and control the centrifugal force to control the ratio of the major axis/minor axis.
The granulated product before drying is soft because the binder contains water and is in a swollen state, and if the particle size (extrusion hole diameter) is large, it is also affected by its own weight. Therefore, when a rotational motion is applied, centrifugal force and own weight act, and the cross section of the granules is flattened (generation of long and short diameters).

<<granularity>>
In the water-floating pesticide formulation of the present invention, the particle size is determined by sieving 100 g of the formulation with test sieves with openings of 2.80 mm and 1.70 mm, and based on the weight of the formulation remaining on the 1.70 mm sieve. , is calculated from the following equation (1).

In the water-floatable pesticide formulation of the present invention, adjusting the particle size contributes to the buoyancy and diffusibility of the formulation. From the viewpoint of balance between floating property and diffusibility, the particle size must be 80% by weight or more in the range of 2.80 mm to 1.70 mm, and more preferably 90% by weight or more. In terms of particle size, particles smaller than this range have less buoyant carriers and tend to sink due to less buoyancy, while particles with a larger particle size have a greater weight per particle and slow movement on the water surface. , the diffusibility worsens.

As a method for adjusting the particle size, the extrusion pore size is adjusted during granulation in the extrusion granulation process, and then the particle size is controlled by appropriately adjusting the length of the granules before drying in the granulation process. method. The grain sizer used for adjusting the particle size is not particularly limited, but a drum type grain sizer, a rotary grain sizer such as Marumerizer, and a crushing type grain sizer such as pin mill, oscillator, rundel mill, and nebulizer can be used. can be used. From the standpoint of economic efficiency and labor saving during production, a rotary grain sizer such as a drum type grain sizer capable of simultaneously adjusting the length/breadth ratio of the bottom surface of grains is preferred.

《Number of grains per gram》
In the water-floating pesticide formulation of the present invention, the number of grains per 1 g is obtained by measuring the number of grains in 5.0 g of the weighed formulation with a grain number counter, and dividing the measured value by 1/5 (rounded off to the nearest whole number). is indicated by

In the water-floating agricultural chemical formulation of the present invention, adjusting the number of grains per 1 g contributes to the floating properties and diffusibility of the formulation. It is essential that the number of grains per 1 g is 50 to 150 from the viewpoint of the balance between buoyancy and diffusion. For the same reason as the particle size above, if the number of grains per gram is more than 150, the grains are smaller and less buoyant, making them easier to sink. slows down and spreads poorly.
In addition, when polyoxyalkylene alkyl ether phosphate and propylene glycol are contained, even grains with small buoyancy diffuse farther due to the enhancement of diffusibility, so the upper limit of the number of grains per 1 g can be up to 200. .

As a method for adjusting the number of grains per 1 g, there is a method of controlling the number of grains per 1 g by crushing the granules before drying in the sizing step. The grain sizer used for adjusting the number of grains is not particularly limited, but a drum type grain sizer, a rotary grain sizer such as a Marumerizer, a pin mill, an oscillator, a rundel mill, a crushing type grain sizer such as a nebulizer can be used. machine can be used. From the viewpoint of economic efficiency and labor saving during production, a rotary grain sizer such as a drum type grain sizer capable of simultaneously adjusting the length/breadth ratio of the bottom surface of grains and the grain size is preferred.

In the sizing process, the major axis/minor axis ratio, particle size, and number of grains at the base of the grains may be adjusted at once, or after adjusting the major axis/minor axis ratio of the bottom of the grains, the grain size and the number of grains may be adjusted. good. It is preferable to adjust at once from the viewpoint of omitting the number of steps and improving the economic efficiency of the production.

In the granulation and sizing steps, first, the mixture is granulated using an extrusion granulator such as a basket granulator or a screw granulator. The extrusion pore size during granulation is preferably 2.8 to 3.0 mm in order to adjust the physical properties of the surface-floating agricultural chemical formulation of the present invention. With the extrusion hole diameter, the surface-floating pesticide formulation of the present invention can be obtained by sizing the obtained granules with a machine that applies centrifugal force to the granules, such as a drum-type sizing machine and Marumerizer. , In addition to the major axis/minor axis ratio at the bottom being 1.1 to 1.4, the particle size is 80% by weight or more in the range of 2.80 mm to 1.70 mm, and the number of particles per 1 g is 50 to 150 Can be sized.

Next, test examples demonstrate the usefulness of the water-floating agricultural chemical formulation of the present invention.
<Diffusivity test 1 (confirmation of diffusivity in shallow water, tailwind conditions)>
The paddy field after transplanting rice is divided with corrugated sheets so that the area of 1 section is 100 square meters (4m x 25m, the depth of water is 2cm). 25 g of the sample prepared according to No. 1 was treated, and the following three items were investigated.
(1) Visual observation of the longest formulation reaching distance 15 minutes after spraying (2) Presence or absence of sediment at the spraying point 15 minutes after spraying The sediment was evaluated according to the following standard table.

(3) Then, 48 hours after the treatment, starting from the spraying point of the test area, 20 mL of water was collected at intervals of 1 m, and the above formulation sample was placed in a separately prepared 1 square meter (1 m × 1 m, water depth of 2 cm) test area. After 48 hours of uniformly spraying 0.25 g, the active ingredient concentration in the sampled water is quantified by high performance liquid chromatography (HPLC) or gas chromatography (GC) (if decomposition products are generated, Quantitate the substances, convert them to pesticidal active ingredient concentrations, and sum them up), and the diffusion rate (%) at each point was calculated by the following formula (2).

The diffusion distance was defined as the maximum distance at points where the diffusion rate was 90% or more, and the diffusion property was evaluated. In addition, this test was performed on the product immediately after preparation and the product stored at 40° C. for 90 days (equivalent to storage at room temperature for 3 years).

<Diffusivity test 2 (confirmation of diffusivity in shallow water, no wind conditions)>
Divided with corrugated plates so that the area of 1 section is 120 square meters (4 m × 30 m, flooded depth 2 cm), 30 g of the sample prepared according to the example is treated from one side of the 4 m side under windless conditions, and the following 3 We investigated the items.
(1) Visual observation of the longest formulation reaching distance 15 minutes after spraying (2) Presence or absence of sediment at the spraying point 15 minutes after spraying The sediment was evaluated according to the above standard table.
(3) Then, 24 hours after the treatment, starting from the spraying point of the test plot, 20 mL of water was sampled at intervals of 1.5 m, and a separately prepared 1 square meter (1 m × 1 m, flooded depth of 2 cm) test plot. After 24 hours of uniformly spraying 0.25 g of the formulation sample, the active ingredient concentration in the sampled water was quantified by high performance liquid chromatography (HPLC) or gas chromatography (GC) (if decomposition products were generated, , and decomposed products were also quantified, converted into pesticidal active ingredient concentrations, and totaled), and the diffusion rate (%) at each point was calculated by the above formula (2).

The diffusion distance was defined as the maximum distance at points where the diffusion rate was 90% or more, and the diffusion property was evaluated. In addition, this test was performed on the product immediately after preparation and the product stored at 40°C for 150 days (equivalent to storage at room temperature for 5 years).

As a result of the diffusivity test, it can be evaluated that the formulation with less sediment at the spraying point and the longer the formulation reaching distance and the longer the point where the diffusivity is 90% or more, the better the buoyancy and diffusibility. .

The sedimentation was affected by the floating carrier, sodium alkylnaphthalene sulfonate or sodium dialkylsuccinate sulfonate, particle size, major/minor axis ratio of the base of the granules, and the number of granules per gram. In Tables 2-1 to 2-5, Examples 1 to 85 satisfying all the requirements had sedimentation, formulation reaching distance, and diffusion distance within practically acceptable ranges. On the other hand, the comparative examples in which any of the constituent elements were omitted or replaced with substitutes resulted in practically problematic sediments at the time of preparation or after storage at 40° C. for 90 days.
In any of the examples, the formulations to which either alkylnaphthalenesulfonate-formaldehyde condensate Na, naphthalenesulfonate-formaldehyde condensate Na, or partially desulfonated sodium lignosulfonate were added showed performance after 90 days at 40°C. (sediment, formulation reaching distance, diffusion distance) decrease was suppressed. In addition, the formulation containing carboxymethyl cellulose Na as a binder had improved sedimentation and diffusion distance compared to the examples using other binders. Comprehensive diffusibility is determined by shirasu balloons, sodium alkylnaphthalene sulfonate or sodium dialkylsuccinate sulfonate, sodium alkylnaphthalene sulfonate formaldehyde condensate, and naphthalene sulfonate formaldehyde condensate. containing either Na or partially desulfonated sodium lignosulfonate, containing carboxymethyl cellulose Na as a binder, having a particle size of 90% by weight or more in the range of 2.80 mm to 1.70 mm, and the bottom surface of the grain Examples 16, 17, 33, and 34 having a major axis/minor axis ratio of 1.1 to 1.4 and a grain number per gram of 50 to 150

In addition, in the examples containing polyoxyalkylene alkyl ether phosphate and propylene glycol, in particular, the particle size is 90% by weight or more in the range of 2.80 mm to 1.70 mm, and the floating carrier has an average particle size of 90 to 120 μm. Formulations using shirasu balloons, preparations to which any of alkylnaphthalenesulfonate formaldehyde condensate Na, naphthalenesulfonate formaldehyde condensate Na, or lignosulfonate Na was added, and carboxymethylcellulose Na or polyvinyl alcohol as binders. The formulation showed superior sedimentation, formulation reaching distance, and diffusion distance during preparation or storage at 40°C for 150 days. Comprehensive diffusibility is determined by shirasu balloons, sodium alkylnaphthalene sulfonate or sodium dialkylsuccinate sulfonate, sodium alkylnaphthalene sulfonate formaldehyde condensate, and naphthalene sulfonate formaldehyde condensate. Contains either Na or Na lignosulfonate, contains carboxymethyl cellulose Na or polyvinyl alcohol as a binder, has a particle size of 90% by weight or more in the range of 2.80 mm to 1.70 mm, and the major diameter of the bottom surface of the grain Examples 102, 121, 140, and 159 having a /minor axis ratio of 1.1 to 1.6 were the best, including immediately after preparation and after 150 days at 40°C.

Based on the above, in order for surface-floating pesticide formulations to exhibit diffusivity, which is a combination of sediment, formulation reaching distance, and diffusion distance, not only immediately after preparation but also after long-term storage, it is necessary to Carrier, polyoxyalkylene alkyl ether phosphate, and sodium alkylnaphthalene sulfonate or sodium dialkylsuccinate sulfonate, particle size of 80% by weight or more in the range of 2.80 mm to 1.70 mm, long diameter/short diameter of the bottom of the grain Diameter ratio is 1.1 to 1.6
