　本発明は、植物の病害防除剤および病害防除方法に関する。より詳細には、本発明は、ディアポルテ・デストルエンス（Diaporthe destruens）、アルターナリア・ソラニ（Alternaria solani）、リゾクトニア・ソラニ（Rhizoctonia solani）、フィロスティクタ・ジンギベリス（Phyllosticta zingiberis）、セラトシスティス・パラドクサ（Ceratocystis paradoxa）、およびアルブゴ・マクロスポラ（Albugo macrospora）等をはじめとする糸状菌によって引き起こされる植物の病害防除剤および病害防除方法に関する。 TECHNICAL FIELD The present invention relates to a plant disease control agent and a disease control method. More particularly, the present invention relates to Diaporthe destruens , Alternaria solani , Rhizoctonia solani , Phyllosticta zingiberis , Ceratocystis paradoxa Ceratocystis paradoxa and Albugo macrospora .
　病原性の糸状菌および病原性の細菌による植物病害の防除は、農業関係者にとって非常に重要な問題である。植物の病害は、罹病種子・苗木・枝・塊茎・球根を植える種苗汚染や、土壌がすでに汚染されている土壌汚染、土壌に残る罹病残渣による伝染等の一次伝染と、風雨等により隣接する土壌からの二次伝染がある。 　The control of plant diseases caused by pathogenic filamentous fungi and pathogenic bacteria is a very important issue for agricultural stakeholders. Plant diseases are caused by primary infection such as contamination of seeds and seedlings for planting diseased seeds, seedlings, branches, tubers, and bulbs, soil contamination in which the soil is already contaminated, infection by diseased residues remaining in the soil, and adjacent soil caused by wind and rain. There is secondary infection from
　病原性の糸状菌および病原性の細菌による植物病害の防除方法としては、限定するものではないが、農薬による、苗浸漬、茎葉散布、種子処理、箱処理、土壌散布、土壌潅注、土壌混和等の処理方法があり、対象植物の病害に応じて、農薬の種類や処理方法を適宜組み合わせて行っている。 Methods for controlling plant diseases caused by pathogenic filamentous fungi and pathogenic bacteria include, but are not limited to, seedling soaking, foliage spraying, seed treatment, box treatment, soil spraying, soil irrigation, soil mixing, etc. Depending on the disease of the target plant, the type of pesticide and treatment method are appropriately combined.
　従来、うどんこ病菌、さび病菌、腐敗病菌等によって引き起こされる広範な植物の病害を対象とする化合物が知られている（例えば、特許文献１参照）。特許文献１には、この化合物を、植物、植物の部分、育成地に施用することが記載されている。 Conventionally, compounds that target a wide range of plant diseases caused by powdery mildew fungi, rust fungi, putrefactive fungi, etc. are known (see, for example, Patent Document 1). Patent Document 1 describes the application of this compound to plants, plant parts and growing grounds.

　昨今の、日照時間、降雨量、温湿度の急激な変化により、これまで問題とならなかった植物の病害が問題となっている。例えば、サツマイモの基腐病は、ディアポルテ・デストルエンス（Diaporthe destruens）という糸状菌に感染することにより、苗床や本圃、貯蔵中の塊根等で発生する病害である。サツマイモの基腐病は、もともと、北米、南米、アフリカ、ニュージーランドに分布していた病害であるが、近年、アジアでも報告されている。日本においては、２０１８年に沖縄で初めて報告され、鹿児島（２０１８年）、宮崎（２０１９年）、茨城（２０２１年）等といったサツマイモの主要な生産地に急速に広まっており、収穫量の減少が問題となっている。 Due to recent rapid changes in sunshine hours, rainfall, and temperature and humidity, plant diseases, which were not a problem until now, have become a problem. For example, root rot of sweet potato is a disease caused by infection with a filamentous fungus called Diaporthe destruens , which occurs in nurseries, main fields, tuberous roots during storage, and the like. The root rot of sweet potato was originally distributed in North America, South America, Africa, and New Zealand, but in recent years, it has also been reported in Asia. In Japan, it was first reported in Okinawa in 2018, and is rapidly spreading to major sweet potato producing areas such as Kagoshima (2018), Miyazaki (2019), and Ibaraki (2021), and the decrease in yield has been observed. It's a problem.
　植物の病害に対しては、本圃に病原菌を持ち込まないことが重要であるが、病害が発生した場合、本圃で病原菌を増やさないことや、病原菌を残さない対策が必要である。したがって、前年に病害が発生した本圃においては、生育土壌における病原菌の菌密度を下げることが有効な病害対策手段の一つとなる。 For plant diseases, it is important not to bring pathogens into the main field, but if a disease occurs, it is necessary to take measures not to increase the pathogens in the main field and to prevent pathogens from remaining. Therefore, in this field where disease occurred in the previous year, reducing the density of pathogenic bacteria in the growing soil is one of the effective disease control measures.
　ところで、病原菌に対して農薬を施用すると、病原菌が残存した場合にその農薬に対する耐性菌が生じることが知られている。したがって、植物の生育土壌に農薬を施用して病原菌の菌密度を下げる場合、病原菌が残存しないよう十分な量の病害防除剤を散布する必要がある。一方で、病害防除剤の散布量が過剰になると、環境や植物に残留することが懸念される。よって、生育土壌における病原菌の菌密度を下げることを目的とした農薬の種類やその使用量は極めて限定的である。 By the way, it is known that when pesticides are applied to pathogens, if the pathogens remain, they will become resistant to the pesticides. Therefore, when a pesticide is applied to the growing soil of a plant to reduce the bacterial density of pathogenic bacteria, it is necessary to spray a sufficient amount of the disease control agent so that the pathogenic bacteria do not remain. On the other hand, if the amount of the disease control agent applied is excessive, there is a concern that it will remain in the environment and plants. Therefore, the types and amounts of pesticides used for the purpose of lowering the density of pathogenic bacteria in growing soil are extremely limited.
　本発明者らは、今般、鋭意検討した結果、糸状菌（例えば、ディアポルテ・デストルエンス（Diaporthe destruens）、アルターナリア・ソラニ（Alternaria solani）、リゾクトニア・ソラニ（Rhizoctonia solani）、フィロスティクタ・ジンギベリス（Phyllosticta zingiberis）、セラトシスティス・パラドクサ（Ceratocystis paradoxa）、およびアルブゴ・マクロスポラ（Albugo macrospora）からなる群から選択される少なくとも１種（以下、「特定の病原菌」ともいう））によって引き起こされる病害に対して、ＱｏＩ殺菌剤、ＱｉＩ殺菌剤、酸化的リン酸化阻害剤、ＳＤＨＩ殺菌剤、ＱｏＳＩ殺菌剤、複合体Ｉ・ＮＡＤＨ酸化還元酵素剤、酸化的リン酸化・ＡＴＰ合成酵素の阻害剤、およびその他呼吸阻害剤からなる群から選択される少なくとも１種を有効成分として含んでなる、植物の病害防除剤を施用すると、植物の病害を有意に防除できることを見出した。本発明はかかる知見に基づくものである。 The present inventors, as a result of intensive studies, found that filamentous fungi (e.g., Diaporthe destruens , Alternaria solani , Rhizoctonia solani , Phyllostikta zingiberis ( against diseases caused by at least one selected from the group consisting of Phyllosticta zingiberis , Ceratocystis paradoxa , and Albugo macrospora (hereinafter also referred to as "specific pathogen") , QoI fungicides, QiI fungicides, oxidative phosphorylation inhibitors, SDHI fungicides, QoSI fungicides, complex I NADH oxidoreductase agents, inhibitors of oxidative phosphorylation, ATP synthase, and other respiratory It has been found that plant diseases can be significantly controlled by applying a plant disease control agent containing as an active ingredient at least one selected from the group consisting of inhibitors. The present invention is based on such findings.
　本発明の植物の病害防除剤の一態様によれば、ＱｏＩ殺菌剤、ＱｉＩ殺菌剤、酸化的リン酸化阻害剤、ＳＤＨＩ殺菌剤、ＱｏＳＩ殺菌剤、複合体Ｉ・ＮＡＤＨ酸化還元酵素剤、酸化的リン酸化・ＡＴＰ合成酵素の阻害剤、およびその他呼吸阻害剤からなる群から選択される少なくとも１種を有効成分として含んでなる。糸状菌（例えば、特定の病原菌）に対して、上記有効成分が有効に作用すること、特に、土壌混和して施用することで、有効成分を植物に残留させることなく、耐性菌の発生を抑制できる十分な量を施用でき、植物の病害を有意に防除できることは、本発明者らによって見出された意外な事実である。 According to one aspect of the plant disease control agent of the present invention, QoI fungicide, QiI fungicide, oxidative phosphorylation inhibitor, SDHI fungicide, QoSI fungicide, complex I NADH oxidoreductase agent, oxidative It comprises, as an active ingredient, at least one selected from the group consisting of phosphorylation/ATP synthase inhibitors and other respiratory inhibitors. Effective action of the above-mentioned active ingredient against filamentous fungi (e.g., specific pathogenic bacteria), especially by mixing with soil and applying it, suppressing the occurrence of resistant bacteria without leaving the active ingredient in the plant. It is an unexpected fact found by the present inventors that a sufficient amount can be applied and plant diseases can be significantly controlled.
　さらに、トリフロキシストロビン等の土壌半減期が長くない薬剤は、施用後に速やかに環境中で分解されるため、環境負荷が小さい一方で、その効果が長期間持続しないというのが当技術分野における技術常識である。しかしながら、かかる技術常識に反して、トリフロキシストロビン等の土壌半減期が長くない薬剤を含む病害防除剤を施用した場合（特に、土壌表面へ散布処理し、土壌混和した場合）であっても、糸状菌によって引き起こされる病害（例えば、特定の病害、特に、かんしょ基腐病）に対して予想外の高い効果を示すことが本発明者らの検討により明らかとなった。本発明はかかる知見に基づくものである。 Furthermore, agents such as trifloxystrobin, which do not have a long half-life in the soil, are quickly decomposed in the environment after application, and thus have a small environmental impact, but their effects do not last for a long period of time. It is technical common sense. However, contrary to such common general knowledge, even when a disease control agent containing a drug with a short soil half-life such as trifloxystrobin is applied (especially when it is sprayed on the soil surface and mixed with the soil) The present inventors' studies have revealed that it exhibits unexpectedly high efficacy against diseases caused by filamentous fungi (for example, specific diseases, especially rot of the root). The present invention is based on such findings.
　したがって、本発明の一態様によれば、予め設定された閾値以下の土壌半減期を有するＱｏＩ殺菌剤を有効成分として含んでなる、土壌混和用の植物の病害防除剤であって、
　前記病害が、糸状菌によって引き起こされる病害である、病害防除剤が提供される。 Therefore, according to one aspect of the present invention, a soil-mixable plant disease control agent comprising, as an active ingredient, a QoI fungicide having a soil half-life equal to or less than a preset threshold,
A disease control agent is provided, wherein the disease is a disease caused by a filamentous fungus.
　また、本発明の一態様によれば、予め設定された閾値以下の土壌半減期を有するＱｏＩ殺菌剤を有効成分として含んでなる植物の病害防除剤の有効量を、植物の生育土壌に散布した後、混和する工程、を含む、植物の病害防除方法であって、
　前記病害が、糸状菌によって引き起こされる病害である、病害防除方法が提供される。 In addition, according to one aspect of the present invention, an effective amount of a plant disease control agent comprising a QoI fungicide having a soil half-life of a preset threshold value or less as an active ingredient was sprayed on the soil where plants grow. After that, a method for controlling plant diseases, comprising a step of mixing,
A disease control method is provided, wherein the disease is a disease caused by a filamentous fungus.
　本発明の植物の病害防除方法の一態様によれば、糸状菌（例えば、特定の病原菌）によって引き起こされる病害に対して、ＱｏＩ殺菌剤、ＱｉＩ殺菌剤、酸化的リン酸化阻害剤、ＳＤＨＩ殺菌剤、ＱｏＳＩ殺菌剤、複合体Ｉ・ＮＡＤＨ酸化還元酵素剤、酸化的リン酸化・ＡＴＰ合成酵素の阻害剤、およびその他呼吸阻害剤からなる群から選択される少なくとも１種を有効成分として含んでなる植物の病害防除剤の有効量を、植物の生育土壌に散布した後、混和する工程、を含む。糸状菌（例えば、特定の病原菌）に対して、上記有効成分が有効に作用すること、特に、植物の生育土壌に散布した後、混和して施用することで、有効成分を植物に残留させることなく、耐性菌の発生を抑制できる十分な量を施用でき、植物の病害を有意に防除できることも、本発明者らによって見出された意外な事実である。 According to one aspect of the plant disease control method of the present invention, QoI fungicides, QiI fungicides, oxidative phosphorylation inhibitors, and SDHI fungicides against diseases caused by filamentous fungi (e.g., specific pathogens) , QoSI fungicides, complex I/NADH oxidoreductase agents, inhibitors of oxidative phosphorylation/ATP synthase, and other respiration inhibitors. A step of applying an effective amount of the disease control agent of (1) to the soil in which the plant grows, and then mixing. The active ingredient acts effectively against filamentous fungi (e.g., specific pathogenic fungi), and in particular, the active ingredient remains in the plant by being mixed and applied after being sprayed on the soil where the plant grows. It is also an unexpected fact discovered by the present inventors that the plant can be applied in a sufficient amount to suppress the development of resistant bacteria without causing any damage, and that plant diseases can be significantly controlled.

　本発明の植物の病害防除方法の一態様によれば、ＱｏＩ殺菌剤、ＱｉＩ殺菌剤、酸化的リン酸化阻害剤、ＳＤＨＩ殺菌剤、ＱｏＳＩ殺菌剤、複合体Ｉ・ＮＡＤＨ酸化還元酵素剤、酸化的リン酸化・ＡＴＰ合成酵素の阻害剤、およびその他呼吸阻害剤からなる群から選択される少なくとも１種を有効成分として含んでなる植物の病害防除剤の有効量を、植物の生育土壌に散布した後、混和する工程（以下、「施用工程」ともいう）、を含み、病害が、糸状菌（例えば、ディアポルテ・デストルエンス（Diaporthe destruens）、アルターナリア・ソラニ（Alternaria solani）、リゾクトニア・ソラニ（Rhizoctonia solani）、フィロスティクタ・ジンギベリス（Phyllosticta zingiberis）、セラトシスティス・パラドクサ（Ceratocystis paradoxa）、およびアルブゴ・マクロスポラ（Albugo macrospora）からなる群から選択される少なくとも１種）によって引き起こされる病害である。
　病害防除剤、植物、糸状菌（例えば、特定の病原菌）についての詳細は、上記と同様である。 According to one aspect of the plant disease control method of the present invention, QoI fungicide, QiI fungicide, oxidative phosphorylation inhibitor, SDHI fungicide, QoSI fungicide, complex I NADH oxidoreductase agent, oxidative After spraying an effective amount of a plant disease control agent comprising as an active ingredient at least one selected from the group consisting of phosphorylation/ATP synthase inhibitors and other respiration inhibitors to the soil where plants grow. , the step of mixing (hereinafter also referred to as “application step”), and the disease is caused by filamentous fungi (for example, Diaporthe destruens , Alternaria solani , Rhizoctonia solani ), Phyllosticta zingiberis , Ceratocystis paradoxa , and at least one selected from the group consisting of Albugo macrospora ).
Details of disease control agents, plants, fungi (eg, certain pathogens) are the same as above.
　本発明の植物の病害防除方法の一態様によれば、施用工程は、植物の苗を定植する当日～４週間前に、病害防除剤を生育土壌に散布した後、混和する工程である。病害防除剤は、植物の苗を定植する当日～３週間前に散布することが好ましく、当日～２週間前に散布することがより好ましく、当日～１週間前に散布することがさらに好ましく、当日～３日前に散布することがさらにより好ましい。 According to one aspect of the plant disease control method of the present invention, the application step is a step of spraying the disease control agent on the growth soil and then mixing it from the day to four weeks before planting the seedlings. The disease control agent is preferably sprayed on the day to 3 weeks before planting seedlings, more preferably on the day to 2 weeks before, even more preferably on the day to 1 week before. Even more preferred is application ˜3 days in advance.
　本発明の植物の病害防除方法の一態様によれば、施用工程は、生育土壌に病害防除剤を単回～３回散布する。病害防除剤は、単回～２回散布することが好ましく、単回散布することがより好ましい。 According to one aspect of the plant disease control method of the present invention, the application step includes spraying the disease control agent on the growing soil once to three times. The disease control agent is preferably sprayed once or twice, and more preferably sprayed once.
　本発明の植物の病害防除方法の一態様によれば、病害防除剤の散布量は、植物の生育土壌の面積に応じて適宜設定することができ、例えば、１（L/10a）以上２５０（L/10a）以下が好ましく、２（L/10a）以上２００（L/10a）以下がより好ましく、３（L/10a）以上１５０（L/10a）以下がさらに好ましく、４（L/10a）以上１００（L/10a）以下がさらにより好ましい。なお、散布量の単位（L/10a）は、１０アール（a）あたりの散布量（L）を示す。 According to one aspect of the plant disease control method of the present invention, the application amount of the disease control agent can be appropriately set according to the area of the soil where the plant grows. L / 10a) or less is preferable, 2 (L / 10a) or more and 200 (L / 10a) or less is more preferable, 3 (L / 10a) or more and 150 (L / 10a) or less is more preferable, 4 (L / 10a) More than 100 (L/10a) or less is even more preferable. The unit of application amount (L/10a) indicates the application amount (L) per 10 ares (a).
　病原菌に対して農薬を施用すると、病原菌が残存した場合にその農薬に対する耐性菌が生じることが知られている。病害防除剤を植物の生育土壌に散布して耐性菌が発生した場合、その土壌を他の農薬で処理するか、耐性菌を含めた病原菌が死滅するまで休耕する必要が生じる。一方で、病害防除剤を過剰に施用すると、病害防除剤の有効成分が植物に残留することが懸念される。これに対して、本発明の植物の病害防除方法においては、病害防除剤の有効成分を植物に残留させることなく、耐性菌の発生を抑制できる十分な量を施用でき、植物の病害を有意に防除できる。 It is known that when pesticides are applied to pathogens, if the pathogens remain, they will become resistant to the pesticides. When a disease control agent is sprayed on plant growth soil and resistant bacteria are generated, it becomes necessary to treat the soil with other pesticides or leave the soil fallow until pathogenic bacteria including resistant bacteria are killed. On the other hand, when the disease control agent is applied excessively, there is concern that the active ingredient of the disease control agent may remain on the plant. In contrast, in the plant disease control method of the present invention, a sufficient amount that can suppress the occurrence of resistant bacteria can be applied without leaving the active ingredient of the disease control agent on the plant, and the plant disease can be significantly suppressed. It can be controlled.
　本発明の植物の病害防除方法の一態様において、生育土壌に散布する病害防除剤の有効量とは、５００（g a.i./ha）以上４０００（g a.i./ha）以下となる量が挙げられ、７５０（g a.i./ha）以上３５００（g a.i./ha）以下となる量が好ましく、９００（g a.i./ha）以上３０００（g a.i./ha）以下となる量がより好ましく、１０００（g a.i./ha）超２５００（g a.i./ha）以下となる量がさらに好ましい。 In one aspect of the plant disease control method of the present invention, the effective amount of the disease control agent to be applied to the growing soil includes an amount of 500 (g a.i./ha) or more and 4000 (g a.i./ha) or less, The amount of 750 (g a.i./ha) or more and 3500 (g a.i./ha) or less is preferable, and the amount of 900 (g a.i./ha) or more and 3000 (g a.i./ha) or less is more preferable, and 1000 (g a.i./ha) ha) more than 2500 (g a.i./ha) or less is more preferred.
　病害防除剤の有効成分として、トリフロキシストロビンを例に挙げると、当業者であれば、植物への残留を懸念して上記に示す有効量のように高用量を施用しない。しかしながら、本発明者らは、この理論に拘束されるものではないが、トリフロキシストロビンの土壌半減期が約６日と極めて短いことから、植物に取り込まれて残留するよりも早く分解することを見出した。したがって、トリフロキシストロビンまたはその塩を有効成分として含んでなる病害防除剤の有効量として、上記に示す高用量を施用しても、植物に有効成分を残留することを抑制でき、生育土壌における病原菌の残存の可能性を極度に低減し、耐性菌の発生を防止できることを見出した。このことは、当分野の技術常識を超える予想外の事実である。 Taking trifloxystrobin as an example of an active ingredient of a disease control agent, those skilled in the art would not apply a high dose such as the effective dose shown above due to concerns about its residue on plants. However, without being bound by this theory, the inventors believe that trifloxystrobin's extremely short soil half-life of about 6 days suggests that it is degraded faster than it can be taken up by plants and retained. I found Therefore, as an effective amount of the disease control agent containing trifloxystrobin or a salt thereof as an active ingredient, even if the high dose shown above is applied, it is possible to suppress the active ingredient from remaining in the plant, and It was found that the possibility of survival of pathogenic bacteria can be extremely reduced and the occurrence of resistant bacteria can be prevented. This is an unexpected fact beyond the technical common sense in this field.
　また、本発明の植物の病害防除方法の一態様によれば、植物の生育土壌に散布するに際し、病害防除剤を希釈して散布することが好ましい。病害防除剤の散布量は、植物の生育土壌の面積に応じて適宜設定することができ、上記に示す高用量の有効量を施用する量であればよい。トリフロキシストロビンまたはその塩を例に挙げると、病害防除剤の散布量は、１（L/10a）以上２５０（L/10a）以下が好ましく、２（L/10a）以上２００（L/10a）以下がより好ましく、３（L/10a）以上１５０（L/10a）以下がさらに好ましく、４（L/10a）以上１００（L/10a）以下がさらにより好ましい。 In addition, according to one aspect of the plant disease control method of the present invention, it is preferable to dilute the disease control agent before spraying it on the soil where the plant grows. The amount of the disease control agent to be applied can be appropriately set according to the area of the soil where the plant grows, and may be an amount that applies a high dose effective amount shown above. Taking trifloxystrobin or a salt thereof as an example, the application amount of the disease control agent is preferably 1 (L/10a) or more and 250 (L/10a) or less, and 2 (L/10a) or more and 200 (L/10a). ) or less, more preferably 3 (L/10a) or more and 150 (L/10a) or less, and even more preferably 4 (L/10a) or more and 100 (L/10a) or less.
　施用工程における病害防除剤の散布方法は、散布量に応じて選択することができ、例えば、ジョウロやハンドスプレー、噴霧器、トラクター等の機械を用いた散布、ドローンを用いた空中散布等が挙げられる。散布量が、５０～１００（L/10a）であれば、ジョウロ、噴霧器を用いて散布できる。散布量が、１～１０（L/10a）であれば、ハンドスプレー、ドローンを用いて散布できる。 The method of spraying the disease control agent in the application step can be selected according to the amount of spraying, and examples thereof include spraying using machines such as watering cans, hand sprays, sprayers, and tractors, and aerial spraying using drones. . If the application amount is 50 to 100 (L/10a), it can be applied using a watering can or a sprayer. If the application amount is 1 to 10 (L/10a), it can be applied using a hand spray or drone.
　本発明の病害防除方法の一態様によれば、トリフロキシストロビンＳＣ、またはトリフロキシストロビンＳＣとフルオピラムＳＣの組合せを有効成分として含み、サツマイモ基腐病の防除として特に有利である。この態様によれば、生育土壌に散布する有効量を、それぞれ、１０００（g a.i./ha）以上２５００（g a.i./ha）以下にすることで、有効成分をサツマイモに残留させることなく、耐性菌の発生を抑制できる十分な量を施用でき、サツマイモ基腐病を有意に防除できる。 According to one aspect of the disease control method of the present invention, trifloxystrobin SC or a combination of trifloxystrobin SC and fluopyram SC is contained as an active ingredient, which is particularly advantageous for controlling sweet potato root rot. According to this aspect, the effective amount to be sprayed on the growing soil is 1000 (g a.i./ha) or more and 2500 (g a.i./ha) or less, respectively, so that the active ingredient does not remain in the sweet potato. can be applied in a sufficient amount to suppress the occurrence of , and can significantly control sweet potato root rot.
　本発明の植物の病害防除方法によれば、土壌がすでに汚染されている土壌汚染等の一次伝染に対して顕著に有利である。ただし、風雨等により隣接する土壌からの二次伝染が生じた場合、従来公知の茎葉散布処理等を組合せて用いてもよい。すなわち、本発明の植物の病害防除方法は、従来公知の他の防除方法を何らするものではない。このような植物の病害防除方法は、土壌汚染等の一次伝染に加え、風雨等により隣接する土壌からの二次伝染も防除できることから、病原菌の防除方法として顕著に有利な手段といえる。 According to the plant disease control method of the present invention, it is significantly advantageous against primary infections such as soil contamination in which the soil is already contaminated. However, if secondary infection from adjacent soil occurs due to wind and rain, etc., conventionally known foliage spraying treatments may be used in combination. That is, the plant disease control method of the present invention does not constitute any other conventionally known control method. Such a plant disease control method can control not only primary infections such as soil contamination, but also secondary infections from adjacent soil due to wind and rain, etc., so it can be said that it is a remarkably advantageous means as a method for controlling pathogenic bacteria.

[{(number of leaves with disease index 0 × 0) + (number of leaves with disease index 1 × 1) + (number of leaves with disease index 2 × 2) + (number of leaves with disease index 3 × 3) + (disease index 4 number of leaves × 4)} / {total number of leaves surveyed (240) × 4}] × 100
　また、下記式により、防除価を算出した。 In addition, the control value was calculated using the following formula.
　防除価（％）＝
［１－｛（病害防除剤（または対照剤）を処理した区画における発病度）／（無処理の区画における発病度）｝］×１００ Control value (%) =
[1-{(Disease rate in plot treated with disease control agent (or control agent))/(Disease rate in untreated plot)}]×100

　結果を図１１に示す。トリフロキシストロビンを含む病害防除剤を、夢誉を播種する前に土壌に散布し、散布した土壌を混和した場合、無処理の区画（発病度：１９．１）と比較して、優位にダイコン亀裂褐変症の発病が抑制された（発病度：９．８／防除価：４８．７％）。さらに、トリフロキシストロビンを含む病害防除剤を、夢誉を播種する前に土壌に散布し、散布した土壌を混和した場合、同様の条件で対照剤であるフルアジアムを処理した場合（発病度：８．５／防除価：５５．５％）と比較して、同程度の発病度および防除価であった。この結果は、土壌半減期（トリフロキシストロビン：約６日、フルアジアム：約９０日）を考慮すると、意外な結果であった。 The results are shown in Fig. 11. When a disease control agent containing trifloxystrobin was sprayed on the soil before sowing Muyoko and the sprinkled soil was mixed, it was superior to the untreated plot (disease rate: 19.1). The onset of radish fissure browning was suppressed (degree of disease: 9.8/control value: 48.7%). Furthermore, when a disease control agent containing trifloxystrobin was sprayed on the soil before sowing Muyoko, and the sprayed soil was mixed, when the control agent Fluasiam was treated under the same conditions (disease rate: 8.5/control value: 55.5%), the disease severity and control value were comparable. This result was an unexpected result considering the half-life in soil (trifloxystrobin: about 6 days, Fluasiam: about 90 days).
　したがって、本発明の病害防除剤は、例えば土壌混和用に用いた場合、有効成分の土壌半減期の長短にかかわらず、糸状菌によって引き起こされる病害を防除できると考えられる。特に、土壌半減期が長くない有効成分を含む病害防除剤を土壌混和用として使用した場合、この理論に拘束されるものではないが、有効成分は、農薬上許容され得ない量が植物体に取り込まれる前に、土壌環境で分解されることから、植物体内における残留農薬量等の観点から従来は適用が困難であった高用量の施用も可能になると考えられる。 Therefore, the disease control agent of the present invention is considered to be able to control diseases caused by filamentous fungi, regardless of the soil half-life of the active ingredient, when used for mixing with soil, for example. In particular, when a disease control agent containing an active ingredient with a short soil half-life is used for soil mixing, the active ingredient is not bound by this theory, but the amount of the active ingredient that is unacceptable for pesticides does not affect the plant body. Since it is decomposed in the soil environment before it is taken up, it is thought that it will be possible to apply a high dose, which has been difficult to apply in the past, from the viewpoint of the amount of residual pesticide in the plant body.

Diaporthe destruens was cultured in a desired medium under dark conditions at 25° C. until a bacterial lawn was formed over the entire 9 cm Petri dish. Next, the medium on which the bacterial lawn was formed was punched out into discs with a diameter of 4 mm using a cork borer. The discs were placed in PDA medium containing trifloxystrobin, azoxystrobin or fluopyram (final concentrations (ppm): 0, 0.005, 0.01, 0.02, 0.03, 0.04, 0.005). 05, 0.1, 1, 5, 10, 50, 100) and cultured for 96 hours at 23° C. in the dark using an incubator (CN-25C, Mitsubishi Electric Engineering Co., Ltd.). After culturing, the long and short diameters of the formed colonies were measured, and based on the reaction rate (%) at each concentration of each disease control agent calculated by the following formula, the half effective concentration (EC 50 ).

{1-(mycelial elongation (mm) in the treatment area of each concentration / mycelial elongation (mm) in the untreated area (0 ppm))} × 100
　結果を図１２に示す。トリフロキシストロビン、アゾキシストロビンまたはフルオピラムのいずれを用いた場合であっても、かんしょ基腐病菌株の菌糸伸長を優位に阻害した（ＥＣ５０はそれぞれ、０．０００４２、０．００９２１または８．０３ｐｐｍ）。特に、ＱＯＩ殺菌剤であるトリフロキシストロビンまたはアゾキシストロビンを用いた場合、ＳＤＨＩ殺菌剤であるフルオピラムを用いた場合と比較して、低濃度であってもかんしょ基腐病菌株の菌糸伸長を阻害した。さらに、ＱＯＩ殺菌剤の中でも、トリフロキシストロビンを用いた場合のほうが、アゾキシストロビンを用いた場合と比較して、より低濃度でかんしょ基腐病菌株の菌糸伸長を阻害した。 The results are shown in FIG. Whether trifloxystrobin, azoxystrobin or fluopyram were used, they significantly inhibited hyphal elongation (EC 50 of 0.00042, 0.00921 or 8, respectively). .03 ppm). In particular, when QOI fungicides trifloxystrobin or azoxystrobin were used, hyphal elongation of Distillery root rot strains was significantly reduced compared to when SDHI fungicide fluopyram was used, even at low concentrations. inhibited. Furthermore, among the QOI fungicides, trifloxystrobin inhibited hyphal elongation of the Rhizoma strain at a lower concentration than azoxystrobin.
