雑である。On the other hand, disinfection of soil with chlorine dioxide gas has an unsolved problem for use by general farmers. When chlorine dioxide gas is used, it is extremely difficult to fill a cylinder or the like and transport it due to its explosiveness and toxicity. Even if it is generated and used in the fields of farmers, it is necessary to use a generator that pays sufficient attention to leakage in order to avoid toxicity. Further, in order to introduce the gas into the soil and prevent the escape of the gas, a sufficient coating is required, and the work is extremely complicated.

不可能である。Further, when a solid composition is prepared by mixing powders of sodium chlorite, a solid acid and the like, it is difficult to completely prevent contact with each other, so that decomposition occurs and the product is stabilized over time. It is difficult to prevent the generation of chlorine dioxide gas, which is highly toxic, as well as to secure the properties. In order to prevent it, a method of mixing sodium chlorite and solid acids and other components in a farmer's field at the time of application is also conceivable.
It is not possible to mix the soil so that the dispersion can be ensured over the entire soil.

を完成するに至った。Chlorine dioxide is widely used as an inexpensive bleaching bactericide using soda chlorite and soda chlorate as raw materials. It has 2.6 times the oxidizing power of chlorine, and there is a danger of explosion at 15 vol% or more. For safety and hygiene, the concentration in air must be kept at 0.1 ppm or less. Dissolves about 10 g in 1 L of water at 20 ° C, but for safety, use at 8 g / L or less is desired (disaster prevention guideline). As described above, chlorine dioxide gas has many precautions for safety, but on the other hand, chlorine dioxide water is 8 g /
If it is used at L or less, handling becomes easy. The inventors of the present invention have completed the present invention by studying the characteristics of these chlorine dioxides in order to bring the soil disinfection method into practical use in the agricultural field.

を勘案しておけば深根性作物にも適用できる。When preparing a chlorine dioxide aqueous solution, it is possible to produce it at a place where a controlled chlorine dioxide generator is held and bring it to the field as a chlorine dioxide aqueous solution.
Furthermore, since the generated chlorine dioxide gas is used after being dissolved in water, it can be produced as a chlorine dioxide aqueous solution in a farm field if an appropriate generation method is selected. In this case, a chlorine dioxide aqueous solution can be easily prepared by mixing several components, which are raw materials of chlorine dioxide, in water.
When soil is treated with an aqueous solution of chlorine dioxide, an irritating odor hardly occurs within the range of the application rate of the present invention. After spraying the chlorine dioxide solution, the soil can be homogenized by cultivating. Furthermore, if the same amount of chlorine dioxide component is dissolved in water having a maximum volume of water or more using a watering pipe and the like, and then treated, there will be some fluctuation depending on the type of soil and the water content of soil, but The concentration can be greatly reduced, there is no need to spread tillage, and safety can be ensured and chlorine dioxide can be evenly dispersed, and soil can be surely disinfected. Therefore, it is not limited by the regions having different soil types. In addition, if the tillage depth is taken into consideration in advance, it can be applied to deep-root crops.

If a large amount of chlorine dioxide is required, the method using chlorate is inexpensive, and if importance is placed on simplicity, the method using chlorite is recommended. Typical chlorine dioxide generation methods using sodium chlorite as the raw material are as follows, and the generation method for preparing the chlorine dioxide aqueous solution from the chlorine dioxide aqueous solution raw material in the field or around the field is selected from these. Just do it. Further, when preparing an aqueous solution of chlorine dioxide, each raw material of chlorine dioxide may be dissolved in water, or a part or all of the components in the raw material may be previously prepared as an aqueous solution, and other components may be dissolved during application. A mixture of aqueous solutions may be used.
