Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspoemulsion preparation which does not cause phytotoxicity even when attached to agricultural crops and has excellent storage stability even after long-term storage at low and high temperatures.

[0002]

BACKGROUND OF THE INVENTION Agrochemicals are often applied as a mixture to crops because of the ease of handling or the particular combination having a synergistic effect. For ease of use, it is desirable to provide farmers with premixed liquid formulations for more efficient operation. However, not all combinations of the pesticidal drug substances are compatible or stable for a long period of time. In particular, the liquid and solid ingredients have great compatibility problems and it is very difficult to make a practical mixture.

As one solution to the above problem, a suspo emulsion formulation is known. Suspoemulsion (SE) is an emulsion concentrate (EC) of one component and a suspension concentrate (S) of another component.
C), and various compositions have been studied for ease of handling and the like.

For example, (a) a novel suspoemulsion of a plant-protecting active substance (JP-A-63-83001);
Suspoemulsion formulation without difficulty in the technology of storage stability of fenoxapropethyl using a sulfourea or phenylurea herbicide (JP-A-5-13240)
6), (c) a suspoemulsion preparation in which a sulfonylurea is made into an aqueous dispersion (JP-A-6-199913), (d) a disulfide containing dithiocarbamate as a solid, and triazole, morpholine or pyrimidine as an emulsified component. Spoemulsion preparations (JP-A-8-67603) and the like are known.

However, in the conventional suspoemulsion preparations (a) to (d), in the case of a combination of an emulsion requiring a solvent and a suspension, the adhesion of the drug to agricultural products at the time of application is increased, However, there is a problem in that the active ingredient easily comes into contact with the elongated portion of the agricultural crop because it spreads on the leaf surface after adhering, and causes serious phytotoxicity. In addition, it is known that suspoemulsion preparations generally have a problem that decomposition of a hydrolyzable agricultural chemical base material is greatly accelerated compared to a conventional aqueous suspension composition (flowable).

For example, in the suspoemulsion preparation (c), the decomposition of sulfonylurea is suppressed by using a polyacryl derivative. However, even in the suspoemulsion preparation using this polyacrylic acid derivative, depending on the combination of drugs. The decomposition suppression function does not work effectively.
Further, in the case of the suspoemulsion preparations (a) to (d), when an organic solvent having a high dissolving power is used, there is a problem that aggregation of the suspension and the emulsion easily occurs.

[0007]

The problem to be solved by the present invention is that, even if it adheres to crops, no phytotoxicity occurs and the decomposition of herbicidally active ingredients having high hydrolyzability is effectively suppressed.
Another object of the present invention is to provide a suspoemulsion preparation which has excellent storage stability even after long-term storage at low and high temperatures, and further has excellent dispersibility and diffusibility on the water surface and in water.

The produced suspoemulsion-type agricultural / horticultural pesticide composition can be sprayed at once with the emulsion composition and the suspension composition, which had to be separately sprayed, thereby saving labor. It is. The method of using the suspoemulsion type agricultural / horticultural pesticide composition of the present invention will be described.

The method of using the suspoemulsion type agricultural / horticultural pesticide composition includes application to plants (foliage application),
Application to plant growing soil (soil application), application to rice field water (water application), application to seeds (seed treatment), etc. are considered, and are particularly suitable for use in rice field water (water application). .

When the suspoemulsion-type agricultural / horticultural pesticide composition of the present invention is used on rice paddy water (water surface application), it has excellent water dispersibility and diffusibility. It can be easily sprayed on the paddy field without the user entering the paddy field only by spraying directly onto the paddy field. At this time, the spraying device is not particularly limited, but a plastic container, a paper container and the like which are usually used for a water-suspended agricultural chemical composition or the like may be used. When spraying directly on the paddy field using such plastic containers or paper containers, the amount of spraying differs depending on the type of the filled pesticide bulk material, the content in the formulation, etc., so specify it uniformly. However, 10 to 2000 ml, preferably 50 to 1,000 ml, per 10 ares is applied to paddy fields. For example, if the container is filled to a volume of 50 to 1000 ml, one or two containers per 10 ares may be used for paddy fields. The suspoemulsion-type agricultural / horticultural pesticide composition of the present invention, which is sprayed directly onto a paddy field with a spraying device, is dispersed uniformly on the surface of the water and water at the same time as the chemical is dropped onto the water surface. Therefore, a sufficient control effect is brought about. Moreover, even if the pesticide composition for agricultural and horticultural use of the suspoemulsion type of the present invention adheres to rice, it hardly spreads on the adhering leaf surface, so that the chemical can reach the elongation part of the rice. Few, so there is no risk of causing serious harm.

When the drug is diluted with water and applied, for example, when spraying an agent over an area of 10 m ² , one of the spray tanks may be used.
Just add 5 to 2,000 ml, more preferably about 10 to 1,000 ml of this drug in 0 liter of water,
The spray liquid can be prepared easily and safely by an operator, and a sufficient effect can be obtained for fruit trees, vegetables and the like.

The present suspoemulsion type agricultural / horticultural pesticide composition exhibits the same effect not only on the above-mentioned rice but also on other agricultural products. That is, the addition of the aromatic vinyl tree (e) increases the viscosity of the oil layer at the time of evaporation of water after adhesion, and further develops the adhesive force, so that the agricultural and horticultural pesticide composition after adhesion to the leaf surface can be obtained. Prevents spreading on the leaf surface and prevents the spread of the drug on the growing part of the crop. For this reason, the spread of the drug to the elongated portion, which has been a problem with the conventional suspoemulsion, can be effectively suppressed, and thus serious phytotoxicity such as dying of crops can be effectively prevented.

In addition, the present suspoemulsion type agricultural / horticultural pesticidal composition is capable of forming a chemically unstable sulfonylurea without forming aggregates for a long period of time even under severe temperature changes at high and low temperatures. Such as suppressing the decomposition of
It has good storage stability.

(Test Example 2) Measurement of Storage Stability The prepared suspoemulsion was placed in a 500 ml glass bottle, and each suspoemulsion was prepared immediately after preparation and when stored in a thermostat at 40 ° C. for 3 months. The average particle size (μm) of the emulsion was measured. The results are shown in (Table 2).

Similarly, at -5 ° C. for 3 days, at room temperature for 1 day,
The average particle size (μm) of the suspoemulsion stored at rest for 3 months by repeating the cycle at 0 ° C. for 3 days
Was measured. The results are shown in (Table 3).

The measurement was carried out using a particle size distribution measuring device (LS2
30: manufactured by Coulter Co., Ltd.). In addition, the presence or absence of formation of aggregates was confirmed using an optical microscope (× 400). If the average particle size increases with time, the emulsion may be broken, and the emulsion and the suspension may be aggregated, and there is a problem in terms of storage stability in terms of practicability. Further, the presence of aggregates can be seen by visually observing the state of the preparation using an optical microscope.

(Test Example 3) Chemical stability Each of the prepared suspoemulsions was placed in a 500 ml glass bottle, and immediately after the preparation and when the suspoemulsion was stored in a thermostat at 40 ° C. for 3 months. Measuring the active ingredient concentration of the sulfonylurea compound (SU) in the preparation,
The residual ratio (%) was examined. The results are shown in (Table 2).

Similarly, at -5 ° C. for 3 days, at room temperature for 1 day,
The cycle of 0 ° C. for 3 days was repeated as one cycle, and the active ingredient concentration of the sulfonylurea compound (SU) in the suspoemulsion stored for 3 months was measured, and the residual ratio (%) was examined. The results are shown in (Table 3).

The measurement of the concentration was performed by using high performance liquid chromatography (Gulliver series: manufactured by JASCO Corporation). The measured value was calculated as a ratio (%) to the initial value, with the initial value at the start of the storage test as 100. That is, if it is 100%, the decomposition has not occurred, and the lower the ratio (%), the more the decomposition progresses, which is not suitable as a practical suspoemulsion agent.

(Test Example 4) Viscosity Measurement After the glass bottle of the suspoemulsion agent used in Test Example 1 was inverted 10 times, the viscosity was measured. The results are shown in (Table 3). For the measurement, type B viscometer (BM type,
The measurement conditions were rotor N.
o. 3, rotor speed 60 rpm, formulation temperature 20 ±
Performed at 0.4 ° C. The viscosity is better as the change with time is smaller.

(Test Example 5) Measurement of dispersibility in water 400 ml of water was placed in a 500 ml beaker, and each of the suspoemulsions immediately after preparation and when stored in a 40 ° C incubator for 3 months was pipetted. , 5 drops (about 0.05 ml) were added to observe the diffusion state, and evaluation was performed in the following four steps. The results are shown in (Table 2).

Similarly, at -5 ° C. for 3 days, at room temperature for 1 day,
The cycle of 0 ° C. for 3 days was repeated as one cycle, and the diffusion state of the suspoemulsion stored for 3 months was observed. The results are shown in (Table 3).

The better the diffusion state, the better.

A: The diffusion state is extremely good. The drug is dispersed so as to diffuse on the surface of the water. ：: Good diffusion state. The drug spreads on the surface of the water and drops in the form of droplets while partially diffusing in the water, but is dispersed by the time it reaches the bottom. Δ: The diffusion state is slightly poor. Most of the drug falls to the bottom in the form of droplets, but is dispersed by stirring the beaker with a stick or the like. X: The diffusion state is bad. The drug falls to the bottom in the form of droplets and does not disperse easily even if the beaker is agitated with a stick or the like.

From the results shown in (Table 1) and (Table 2), Comparative Examples 1 to 3 showed strong adhesion damage and poor storage stability such as physical stability and chemical stability. Comparative Examples 7 to
No. 9 showed strong chemical damage and poor chemical stability. In Comparative Examples 4 to 6 in which no resin was added and in Comparative Examples 10 to 12 in which a resin other than the aromatic resin was added, the adhesion harm was also strong. From the results shown in (Table 3), Example 1 was obtained.
No. 8 was chemically stable with no change in particle diameter and viscosity over time even at low temperature (-5 ° C) and high temperature (40 ° C) repetition.

(Test Example 6) Biological effect test The paddy field after rice scraping and transplanting rice was used to measure the length of 30
m, a section having a width of 4 m was prepared. Seven days after the preparation of the plot, a resin ring having a diameter of 20 cm was buried at a total of 7 locations every 5 m from the end of the plot, and seeds of Nobie, Firefly, and annual broadleaf were sown. Seven days later (at the time of germination of lobster, firefly, and annual broadleaf), the condition of flooding was set to about 5 cm.
Each g was processed. After the treatment, the movement of water was stopped for 3 days, and thereafter the field was managed while maintaining the depth of flooding. Investigation was conducted 29 days after the treatment, and the evaluation was made according to the following five grades. The results are shown in (Table 5).
