Description

技術分野
本発明は、2−アニリノ−4(3H)−ピリミジノン誘導体を有効成分として含有する有害生物防除剤、特に、農園芸用、衣食住関連又は家畜・ペット用の分野における、節足動物(昆虫類、ダニ類)、線虫類、蠕虫類もしくは原生動物などの有害生物防除剤、あるいは、農園芸作物に有害な病害及び雑草の防除剤に関する。
背景技術
従来、農園芸分野では、各種病害虫あるいは雑草の防除を目的とした殺菌剤、除草剤及び殺虫、殺ダニ剤が開発され実用に供されている。しかしながら、従来汎用されている農園芸用殺菌剤、除草剤及び殺虫、殺ダニ剤は、効果、スペクトラム、あるいは残効性等の点において必ずしも満足すべきものではない。また、施用回数や施用薬量の低減等の社会的要請を充分満足しているとは言えない。
また、従来汎用されてきた農薬に対して抵抗性を獲得した病害虫の出現も問題となっている。例えば、野菜、果樹、花卉、茶、ムギ類及びイネ等の栽培において、様々な系統の農薬、例えば病害の場面では、トリアゾール系(トリアジメフォン等)、ベンズイミダゾール系(ベノミル、チオファネートメチル等)、ジカルボキシイミド系(プロシミドン、イプロジオン等)、フェニルアミド系(メタラキシル、オキサジキシル等)農薬等に抵抗性を獲得した種々の病害が各地で出現している。一方害虫の場面では、有機リン剤(フェニトロチオン、マラチオン、プロチオフォス、DDVP等)、ピレスロイド系(ペルメトリン、シペルメトリン、フェンバレレート、サイハロスリン等)、ベンゾイルウレア系(ジフルベンズロン、テフルベンズロン、クロルフルアズロン等)、ネライストキシン系(カルタップ、ベンスルタップ等)農薬等に抵抗性を獲得した害虫の防除が年々困難になっている。また、除草剤の場面ではトリアジン系、スルホニルウレア系、フェニルウレア系、フェノキシフェノキシ系、シクロヘキサンジオン系等の農薬において多数の抵抗性雑草が出現している。
さらに、病害虫が未だ抵抗性を獲得していない農薬(例えば、ジチオカーバメート系やフタルイミド系農薬等)もあるが、これらは一般に施用薬量や施用回数が多く、環境汚染等の観点から好ましいものではない。従って、従来汎用の農園芸用殺菌剤及び殺虫、殺ダニ剤に抵抗性を獲得した各種病害虫に対しても低薬量で十分な防除効果を示し、しかも環境への悪影響が少ない新規な殺虫剤の開発が切望されている。殺ダニ剤についても、従来汎用の殺ダニ剤に抵抗性を示すダニに対しても優れた防除効果を示し、安全性の高い殺ダニ剤の開発が期待されている。
また、近い将来予想される世界人口増加に伴う食糧危機の解消には、重要作物の安定供給が必要不可欠である。安定した作物の供給には、その栽培及び収穫時に障害となる雑草の経済的かつ効率のよい枯殺あるいは防除が必要であり、その解決策となる新しい除草剤や植物成長調節剤の開発がますます重要となっている。
一方、WO 93/21162(CN 1079736,EP 636615,Japan Kokai Tokkyo Koho JP 06/321913,US 5518994)には、本発明の化合物と類似の構造を有する2−アニリノ−4(3H)−ピリミジノン誘導体が開示されているが、3位窒素原子上に置換されていてもよいアリール基や置換されていてもよいビニル基を有する2−アニリノ−4(3H)−ピリミジノン誘導体はこれまでに全く記載がない。また、上記公報に記載された2−アニリノ−4(3H)−ピリミジノン誘導体に関しては、除草活性ならびに植物成長調節剤としての生理活性は記載されているが、それ以外の生理活性、例えば殺虫及び殺ダニ活性や殺菌活性等に関する記載は一切なされていない。
発明の開示
本発明の課題は、従来の農園芸用あるいは衣食住関連又は家畜・ペット用の殺菌剤及び殺虫、殺ダニ剤、殺線虫剤等に抵抗性を示す各種病害虫に対して高い防除効果を示し、かつ、作物に対する高い安全性と雑草に対する優れた殺草活性を併せ持つ新規有害生物防除剤を提供することにある。
本発明者等は上記の課題を解決すべく鋭意検討した結果、下記一般式(1)で示されるような、3位窒素原子上に置換されていてもよいアリール基や置換されていてもよいビニル基を有する新規な2−アニリノ−4(3H)−ピリミジノン誘導体が、上記特徴を有する化合物であることを見い出し、本発明を完成させるに至った。

The present invention relates to a pest control agent containing a 2-anilino-4 (3H) -pyrimidinone derivative as an active ingredient, in particular, arthropods (insects) in the fields of agriculture, horticulture, clothing / habitation, livestock / pets. Mite), nematodes, helminths, protozoa and other pest control agents, or diseases and weed control agents harmful to agricultural and horticultural crops.
Background art
Conventionally, in the field of agriculture and horticulture, fungicides, herbicides, insecticides and acaricides for the purpose of controlling various pests or weeds have been developed and put to practical use. However, conventionally used agricultural and horticultural fungicides, herbicides, insecticides and acaricides are not always satisfactory in terms of effects, spectrum, residual effects, and the like. Moreover, it cannot be said that the social request, such as the number of times of application and the amount of applied medicine, is sufficiently satisfied.
In addition, the emergence of pests that have acquired resistance to agricultural chemicals that have been widely used in the past is also a problem. For example, in the cultivation of vegetables, fruit trees, flower buds, tea, wheat, rice, etc., various pesticides, for example, in the case of disease, triazole (triazimephone etc.), benzimidazole (benomyl, thiophanate methyl etc.), Various diseases that have acquired resistance to pesticides such as dicarboximide (procymidone, iprodione, etc.), phenylamide (metalaxyl, oxadixyl, etc.) have appeared in various places. On the other hand, in the pest scene, organophosphorus agents (fenitrothion, malathion, prothiophos, DDVP, etc.), pyrethroids (permethrin, cypermethrin, fenvalerate, cyhalothrin, etc.), benzoylurea (diflubenzuron, teflubenzuron, chlorfluazuron, etc.), Control of pests that have acquired resistance to nereistoxin-based pesticides (cartap, bensultap, etc.) has become difficult year by year. In the field of herbicides, many resistant weeds have appeared in agricultural chemicals such as triazine, sulfonylurea, phenylurea, phenoxyphenoxy, and cyclohexanedione.
In addition, there are some pesticides (such as dithiocarbamate pesticides and phthalimide pesticides) for which pests have not yet acquired resistance, but these are generally preferred in terms of environmental pollution and the like because they have a large amount of applied dose and frequency of application. Absent. Therefore, it is a novel insecticide that exhibits a sufficient control effect at low doses and has little adverse effects on the environment against conventional pesticides for agricultural and horticultural use and various pests that have acquired resistance to insecticides and acaricides. The development of is eagerly desired. As for the acaricide, it shows an excellent control effect against mites that are resistant to conventional general acaricides, and development of a highly safe acaricide is expected.
In addition, a stable supply of important crops is indispensable in order to resolve the food crisis accompanying the expected increase in the world population in the near future. To supply a stable crop, it is necessary to economically and efficiently kill or control weeds that are hindered during cultivation and harvesting, and new herbicides and plant growth regulators will be developed as solutions. It has become increasingly important.
On the other hand, WO 93/21162 (CN 109736, EP 636615, Japan Kokai Tokyo Koho JP 06/321913, US 5518994) includes 2-anilino-4 (3H) -pyrimidinone derivatives having a structure similar to the compound of the present invention. Although disclosed, no 2-anilino-4 (3H) -pyrimidinone derivatives having an aryl group which may be substituted on the 3-position nitrogen atom or an optionally substituted vinyl group have been described so far . Further, regarding the 2-anilino-4 (3H) -pyrimidinone derivative described in the above publication, herbicidal activity and physiological activity as a plant growth regulator are described, but other physiological activities such as insecticide and killing are described. There is no mention of mite activity or bactericidal activity.
Disclosure of the invention
The subject of the present invention shows a high control effect against various insects and pesticides that are resistant to conventional agricultural and horticultural or clothing / living-related or livestock / pet fungicides and insecticides, acaricides, nematicides, etc. And it is providing the novel pest control agent which has the high safety | security with respect to a crop, and the outstanding herbicidal activity with respect to weeds.
As a result of intensive studies to solve the above-mentioned problems, the present inventors, as shown by the following general formula (1), may be an aryl group which may be substituted on the 3-position nitrogen atom or may be substituted. It has been found that a novel 2-anilino-4 (3H) -pyrimidinone derivative having a vinyl group is a compound having the above characteristics, and has completed the present invention.
That is, the present invention relates to the general formula (1)
