【発明の詳細な説明】 本発明は、水稲栽培の病害防除方法に関する。[Detailed description of the invention] The present invention relates to a method for controlling diseases in rice cultivation.

する病害を防除する方法に関する。More specifically, by placing a sheet-like sterilized molded material on the bottom of the rice seedling box, it is possible to prevent soil from leaking from the bottom of the seedling box, and at the same time prevent diseases that may occur in young seedlings during the seedling growing period and/or in the rice after transplanting. Concerning methods of pest control.

問題をひき起す場合がある。In recent years, advances in pest control agents have been remarkable, and highly effective drugs have been developed. However, the methods of application include spraying and scattering powders, granules, or liquids in the fields, but these methods require a great deal of labor and can cause unforeseen consequences as the chemicals scatter to areas other than the intended ones. The impact on the environment may become a problem, and the sprayer may inhale the chemicals, causing health problems.

ていると多量の薬剤が耐着することで薬害を生じること
もある。Conventionally, the development of granules using drugs with permeability has reduced the labor required during spraying, but on the other hand, the effectiveness may lack certainty. In addition, in rice cultivation, applying granules to seedling boxes allows chemical treatment without entering the rice fields, but the time for chemical treatment is limited to just before rice planting, which is a busy season for farmers, so it takes enough time to ensure uniform treatment. It is difficult to do so. In general, the time required to apply seedling boxes is, for example, approximately 3 minutes to evenly treat each seedling box, and 20 seedling boxes are required to plant one seedling, so about 1 hour. It will require. Furthermore, it is necessary to irrigate the seedlings to prevent the chemicals from falling when placing them on the rice transplanter. Moreover, if the treatment is not even and uniform, it may cause chemical damage or may not be sufficiently effective. In addition, if the stems and leaves are wet with dew, rain, or irrigation, a large amount of chemicals may adhere to them, resulting in chemical damage.
薬剤を、育苗用培土に混和することも行われているが、
労力を要する上に、薬剤によっては著しい薬害をもたら
す。Chemicals are also mixed into the soil for raising seedlings, but
In addition to being labor-intensive, some drugs can cause significant drug damage.

昭５２−１４５１５８）。On the other hand, it is already known that fertilizers or pesticides can be easily and effectively applied using a sheet-like molded product carrying fertilizers or pesticides (Japanese Patent Laid-Open Nos. 51-114228 and 1982-145158).

分な効果を示さない場合がある。JP-A-1-19002 describes an agrochemical molded article in which water-soluble paper is impregnated with or supports an agrochemical active ingredient compound. According to the specification of the publication, it is stated that the agrochemical molded product can be applied easily and labor-savingly, and is particularly effective in controlling diseases in seedling boxes. However, since the supporting sheet is water-soluble, the active ingredient elutes faster than necessary, so depending on the type of pesticide molded product,
It may also cause chemical damage to the young seedlings in the seedling box. Additionally, potting soil for raising seedlings generally has poor adsorption of chemicals and the active ingredients may be washed away by watering etc. during the seedling raising period. The drug may not be able to maintain its effectiveness until the time of use and may not show sufficient effects.
また例えば、北日本地域での稲作のように移植後２ケ月
以上を経て、いもち病が発生する場合は、従来の育病箱
施用方法では十分な薬剤の残効性を維持することは困難
であり、十分な効果をあげることはできないと言われて
いる。In addition, for example, in cases where rice blast occurs more than two months after transplanting, such as in rice cultivation in northern Japan, it is difficult to maintain sufficient residual efficacy of the drug using the conventional method of applying rice growing boxes. , it is said that it cannot produce sufficient effects.
本発明者等は、上記問題点を解決することを目的に研究

、稲育苗箱の底面に敷くことにより、培土の漏出を防ぎ
、且つイネの病害を防除する方法を見いだした。The present inventors conducted research with the aim of solving the above problems. As a result, a sheet-like sterilized molded product is produced, in which a water-insoluble paper or mineral sheet is coated with a composition containing a water-soluble glue and one or more bactericidal compounds, or the water-insoluble paper or When manufacturing a mineral sheet, a water-soluble glue and one or more fungicidal compounds were mixed! We have discovered a method for preventing leakage of soil and controlling rice diseases by placing a sheet-like sterilized molded product mixed with the 1j composition on the bottom of a rice seedling box.
本発明方法は、水溶性糊料に殺菌性化合物を保持させて
、薬剤を徐々に溶出せしめ、防除に必要な薬量を苗箱生
育稚苗に吸収させ薬剤の効果を長く維持させることに特
徴がある。The method of the present invention is characterized in that a fungicidal compound is retained in a water-soluble paste, the drug is gradually eluted, and the amount of drug necessary for pest control is absorbed by the young seedlings grown in the seedling box, thereby maintaining the effect of the drug for a long time. There is.

きる上に、水田田面水に溶出して流亡することがほとん
どなく、公害防止の見地からも好ましい処理方法と言え
る。According to the present invention, by combining the concentration and type of glue, it is possible to suppress the elution of the drug relatively easily, and the amount of drug necessary for pest control is absorbed by the young seedlings during the seedling-raising period. In addition to being able to control diseases, the remaining chemicals are reliably transferred to the roots of the seedlings at the time of transplanting together with the glue, paper, or mineral sheet. Therefore, according to the pest control method of the present invention, compared to the case where a chemical is applied to the soil surface,
Since the drug is mainly treated in the rice rhizosphere, it is absorbed by the seedlings at a high rate, making it possible to use it very efficiently and accurately.It also rarely leaks into rice field water and is washed away, reducing pollution. It can be said that this is a preferable treatment method from the viewpoint of prevention.

い鉱物質のものが望ましい。Any water-insoluble paper or mineral sheet used in the method of the present invention can be used as long as it is not particularly acidic or alkaline; however, the paper or mineral sheet may also be transferred to the fields at the time of transplantation. If transferring, use Japanese paper, horse manure paper, or CP, which are susceptible to microbial decomposition for environmental conservation reasons.
It is preferable to use ice balls or mineral substances that do not cause any problems even if they are released into the paddy soil.

Further, as the mineral mat, it is also possible to use a calcium silicate fiber mat, such as Power Mat (manufactured by Zen-Noh), which contains fertilizer components.

After transplanting, maintain the seedlings in a greenhouse at 20-35°C under normal seedling conditions.
The rice blast fungus spore suspension was spray-inoculated according to a conventional method and kept in an inoculation chamber at a temperature of 23 to 25°C and a relative humidity of 100% for 24 hours. Thereafter, they were transferred to a glass greenhouse at a temperature of 20 to 28°C, and 7 days after inoculation, the degree of disease per pot was graded and evaluated according to the following criteria, and the control value (%) was determined.
