Description

  TECHNICAL FIELD The present invention relates to an application method for suppressing powdering and applying an excellent pest control effect in soil application of agricultural chemicals performed in upland farming and the like.

  As a method for controlling soil diseases represented by root-knot disease, root rot disease, or withering disease, a method of mixing a powder with soil is generally used. Since the powder has a fine particle size of 300 mesh or more (46 μm or less), when applied, it is likely to drift to nearby fields, houses, etc. other than the target field even when applied. Therefore, the environment is polluted by the drift of the powder, and there is a risk of causing phytotoxicity to useful crops cultivated in fields other than the control target and adversely affecting the safety of application workers and the like. Therefore, development of a new agricultural chemical formulation or application method with reduced drift is desired.

  As one of means for suppressing drift, use of an additive that imparts a drift preventing effect to the powder, that is, use of a drift preventing agent is known. Examples of such drift inhibitors include those using 0.5 to 5.0% liquid paraffin, dihydric or trihydric alcohol, etc., those containing about 1 to 3% of organic phosphorus compounds, adipic acid The thing using 0.1 to 5.0% of ester is known (for example, refer patent documents 1, 2, and 3). However, although the drift is reduced by these substances, it is difficult to completely suppress the drift.

On the other hand, there is a method of making the particle size larger than the powder as another means for suppressing drift. This method has been put into practical use as a granule (for example, coarse powder, fine granule, fine granule F and the like), and is usually produced by a crush granulation method or a surface coating method. The crushing granulation method is a method in which a granule larger than a granule is first produced by extrusion granulation or the like, and obtained by crushing it to obtain a required particle size (for example, see Non-Patent Document 1). However, these dosage forms have drawbacks such as inferior control effect compared to powders having a fine particle size, and poor production efficiency and high production cost in mass production.
JP-A-48-075730 JP 55-043035 A Japanese Patent Laid-Open No. 09-012407 Agricultural Chemical Society of Japan Pesticide Formulation and Application Method Study Group, “Agricultural Chemical Formulation Guide”, Japan Plant Protection Association, October 30, 1997, p. 17-18

  The problem to be solved by the present invention is a pesticide that reduces the drift compared to the soil mixing treatment of the powder to increase the safety for the environment and application workers, and exhibits a control effect equal to or greater than the soil treatment of the powder. It is to provide an application method.

  As a result of diligent research, the present inventors have demonstrated the control effect equivalent to or better than the conventional soil treatment and soil admixing treatment of powders by applying the agrochemical granular composition produced by the stirring granulation method. I found out that I can make it. That is, the present invention provides a method for applying a pesticide according to the following [1] to [12], a method for controlling pests according to the following [13] (hereinafter referred to as the method according to [1] to [13] below). It is referred to as “the method of the present invention”) and the following [14] pesticide granular composition.

  [1] A method for applying an agrochemical, characterized in that an agrochemical granular composition produced by a stirring granulation method is applied to soil.

  [2] The application method according to [1], wherein the agrochemical granular composition is applied to upland field soil.

  Next, the usefulness of the agrochemical granular composition of the present invention will be specifically described in the following test examples. However, the present invention is not limited to these.

[Test Example 1] Chinese cabbage root-knot disease control effect test [Biological test method and results]
The cruciferous root-knot diseased roots that had been stored in a frozen state were pulverized with a mixer with water, filtered through double gauze, and centrifuged (3000 rpm × 5 minutes) to collect clubroot dormant spores. As it will be 1 × 10 ⁵ cells / soil 1g of soil, the clubroot resting spores was added and the test polluted soil. A 1 / 10000a pot-sized test soil was put in a plastic bag, and the agrochemical granular composition produced in the above formulation example was added so as to be equivalent to 20 kg and 15 kg / 10a and mixed well. Further, a 1 / 10000a pot-sized test soil was put in a plastic bag, and the powder produced in Comparative Formulation Example 2 was added so as to be equivalent to 30 kg / 10a and mixed well. The mixed soil was transferred to a 1 / 10000a pot, Chinese cabbage (variety: Musou) grown for 2 weeks was planted, and after 38 days of treatment, the number of strains according to the degree of root nodules was examined.

The disease severity was calculated according to the following formula.
Disease severity = {Σ (number of diseased strains by degree) × attack index) / (number of strains examined × 3)} × 100
Control value = 100-(Severity of treated area / Untreated severity) x 100
[Disease index]
0: No root knot
0.5: Form a hump on the side root
1: Small root bumps are formed on the main root
2: Forms a large hump in the main root
3: Formed galls on main and side roots. The results are shown in Table 1.
