Description

[Technical Field]

[0001] The present invention relates to a pesticide composition in which the release of cyclopyrimorate is controlled. [Background technology]

[0002] Patent Document 1 discloses that cyclopirimorate is an effective pesticide active ingredient that induces bleaching in paddy broadleaf weeds and sedge weeds of the Cyperaceae family, including arrowhead weed, Monochoria kanazawai, and Scirpus bulrush, causing their death. Because cyclopirimorate has a novel HST inhibitory mechanism, it is also effective against resistant weeds. Furthermore, it is compatible with 4-HPPD inhibitors such as pyrazolate, which also have bleaching effects, and combining them produces a dramatic synergistic effect. Furthermore, the combination of cyclopirimorate and pyrazolate is known to have a broader herbicidal spectrum but is highly safe, causing no phytotoxicity to paddy rice.

[0003] Known means for controlling the release of pesticide active ingredients include, for example, means for processing the pesticide active ingredient itself, such as microencapsulation as described in Patent Document 2, and sustained-release bulk powder as described in Patent Document 3, and means for structurally endowing the pesticide with release control properties, such as hydrophobic substance-coated granules as described in Patent Document 4, and hydrophobic substance-containing granules as described in Patent Document 5.

[0005] There is a need for a technical means that exhibits elution behavior that suppresses the initial elution of the pesticide composition at the time of treatment, while eluting a certain amount or more of the active ingredient over a specified period that can ensure the efficacy of the pesticide active ingredient. Therefore, an object of the present invention is to provide an agricultural chemical composition containing cyclopirimorate and other agriculturally active ingredients, which exhibits excellent dissolution behavior of cyclopirimorate. [Means for solving the problem]

The particle size of the pesticide composition in this embodiment is usually 0.1 to 5 mmφ, preferably 0.3 to 3 mmφ, and more preferably 0.5 to 2 mmφ, because if the particles are too large, drying of the particles becomes difficult, and if the particles are too small, workability in subdivision deteriorates and powdering occurs during use.

[0048] The method for using the pesticide composition in this embodiment can be to manually apply it directly into the paddy field from, for example, a box, bottle, or bag with an appropriate opening, or to apply it using a pesticide sprayer. In this embodiment, the "pesticide sprayer" is an apparatus powered by an engine or a motor, such as an unmanned helicopter, a drone, or a power sprayer.

[0049] In order to avoid moisture, the pesticide composition of this embodiment is preferably stored in a moisture-proof container, etc. Such a container is not particularly limited, but examples thereof include bottles, bags, boxes, etc. made of materials in which resin, aluminum, paper, etc. are bonded together as necessary, or materials in which aluminum or silicic acid is vapor-deposited on the surface of resin, paper, etc. [Example]

The resulting kneaded mixture was extruded and granulated through a 0.8 mm screen. The granulated material was dried in a dryer to obtain a solid pesticide composition.

[0068] (Comparative Example 10) 17.9 parts of the cyclopyrimorate / triafamone / benzobicyclone slurry prepared in Example 1, 3.0 parts of sodium tripolyphosphate, 1.0 parts of Cellogen (registered trademark) 5A, 2.0 parts of SURFYNOL 104S, 2.0 parts of Morwet (registered trademark) D-425 Powder, 20.0 parts of Kunigel V2, and 63.51 parts of calcium carbonate B-90 were mixed and then kneaded with an appropriate amount of water. The resulting kneaded mixture was extruded and granulated through a 0.8 mm screen. The granulated material was dried in a dryer to obtain a solid pesticide composition.

[0069] (Test example) 40 mg of the pesticide composition prepared in the Examples and Comparative Examples was weighed out and placed in a container (approximately 25 cm x 30 cm) filled with water (3-degree hard water) to a depth of 3 cm so as to disperse the composition as uniformly as possible, and then allowed to stand. One day and four days after the addition, water samples were collected, and the concentration of cyclopyrimorate in water (ppm) was quantified by HPLC under the following conditions. From the results obtained, the dissolution rate of cyclopyrimorate in water (concentration in water ÷ concentration at 100% dissolution × 100 (%)) was calculated and evaluated according to the following criteria. (Evaluation criteria for cyclopirimorate dissolution rate after 1 day) 〇: 65% or less ×: Exceeding 65% (Evaluation criteria for cyclopirimorate dissolution rate after 4 days) 〇: 85% or more ×: Less than 85%

[0070] (HPLC conditions) Method: Absolute calibration curve method Column: Zorbax SB-phenyl (3.5 μm, 4.6 × 150 mm) Column temperature: 40℃ Mobile phase: Water (0.01% phosphoric acid) / acetonitrile = 55 / 45

[0071] [Table 1]

[0072] In Table 1, A: Tripolyphosphate B: Alkylbenzene sulfonate C: Polycarboxylate D: Acetylenic dialcohol composition E: Sodium salt of alkylnaphthalenesulfonic acid formalin condensate Table 1 also shows the content of each component in the compositions obtained in the examples and comparative examples in terms of mass %.

[0073] As shown in Table 1, the compositions of the examples were able to achieve control of cyclopyrimorate dissolution (1 day later: 65% or less, 4 days later: 85% or more), which was difficult to achieve with the compositions of the comparative examples. [Industrial Applicability]

[0074] According to the present invention, a highly practical pesticide composition can be provided.
