Description

技術分野
本発明は、2−(置換フェニルイミノ)ピリミジ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に関する。
背景技術
従来、農園芸分野では、各種害虫の防除を目的とした殺虫、殺ダニ剤、殺線虫剤、衛生害虫防除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、様々な系統の殺虫、殺ダニ剤、例えば、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。
さらに、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虫、殺ダニ剤に抵抗性を獲得した各種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。
従来、ピリミジン環4位に置換フェニルイミノ基を有するピリミジン誘導体に関しては、幾つかの特許公報[例えば、Japan Kokai Tokkyo Koho JP 59/181265(EP 123402,US 4612376),EP 168262(JP 61/044872,US 4725600),Japan Kokai Tokkyo Koho JP 61/267522(Chemical Abstracts 106:201735),EP 166564(JP 61/27973,US 4649142),Japan Kokai Tokkyo Koho JP 02/256669(Chemical Abstracts 114:207283),US 4708958(JP 63/096778,EP 261633)]に記載がある。しかし、これらの特許にはいずれも強心作用等を有するとの記載はあるが、有害害虫に対する活性は何ら示されていない。また、Japan Kokai Tokkyo Koho JP 06/157478(Chemical Abstracts 121:300914)号公報には殺虫、殺ダニ活性を有するピリミジン誘導体に関する記載があるが、このピリミジン誘導体においても置換フェニルイミノ基はピリミジン環4位に存在するものであり、本発明の化合物とは異なるものである。
一方、Japan Kokai Tokkyo Koho JP 07/002799(Chemical Abstracts 122:214102)には、除草活性及び植物成長調節剤の作用を有する2−(置換フェニルイミノ)ピリミジン誘導体が開示されている。しかしながら、上記公報にはこれらの化合物の除草活性ならびに植物成長調節剤としての作用以外の生理活性、例えば殺虫、殺ダニ活性や殺菌活性に関する記載は一切なされていない。さらに、2位イミノ基上のフェニル環上に、2個のトリフルオロメチル基を有する誘導体や、2個のトリフルオロメチル基にさらに1個ないし2個のハロゲン原子を導入した誘導体は、具体的な製造例は示されておらず、それらの生物活性に関する記載はない。また、2位イミノ基上のフェニル環上の置換基としてニトロ基を有する2−(置換フェニルイミノ)ピリミジン誘導体はこれまでに全く報告されていない。
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・ペット用の殺虫、殺ダニ剤、殺線虫剤等に抵抗性を示す各種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)で示される新規な2−(置換フェニルイミノ)ピリミジン誘導体が、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- (substituted phenylimino) pyrimidine derivative as an active ingredient, particularly arthropods (insects, ticks) in the fields of agriculture, horticulture, clothing / habitation, livestock / pets. ), Pest control agents such as nematodes, worms or protozoa.
Background art
Conventionally, in the field of agriculture and horticulture, insecticides, acaricides, nematicides and sanitary insecticides for the purpose of controlling various pests have been developed and put into practical use. However, conventionally used agricultural and horticultural 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 conventionally used pesticides is also a problem. For example, in the cultivation of vegetables, fruit trees, flower buds, tea, wheat and rice, various types of insecticides and acaricides, for example, organic phosphorus agents (fenitrothion, malathion, prothiophos, DDVP, etc.), pyrethroids (permethrin, Cypermethrin, fenvalerate, cyhalothrin, etc.), benzoylurea (diflubenzuron, teflubenzuron, chlorfluazuron, etc.), nereistoxin (cartap, bensultap, etc.) It has become.
In addition, there are some pesticides (such as dithiocarbamate and phthalimide pesticides) for which pests have not yet acquired resistance, but these are generally preferred from the viewpoint of environmental pollution and the like because they have a large amount of application and the number of applications. Absent. Therefore, the development of new insecticides that exhibit sufficient control effects at low doses and that have little adverse impact on the environment against various insect pests that have acquired resistance to conventional agricultural and horticultural insecticides and acaricides. Longed for. 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.
Conventionally, with respect to pyrimidine derivatives having a substituted phenylimino group at the 4-position of the pyrimidine ring, several patent publications [for example, Japan Kokai Tokyo Koho JP 59/181265 (EP 123402, US Pat. No. 4,612,376), EP 168262 (JP 61/044872, US 4725600), Japan Kokai Tokyo Koho JP 61/267522 (Chemical Abstracts 106: 201735), EP 166564 (JP 61/27973, US 4649142), Japan Kotak (JP 63/096778, EP 261633)]. However, although these patents all mention that they have a cardiotonic action etc., they do not show any activity against harmful pests. In addition, Japanese Kokai Tokkyo Koho JP 06/157478 (Chemical Abstracts 121: 300914) discloses a pyrimidine derivative having insecticidal and acaricidal activity. In this pyrimidine derivative, the substituted phenylimino group is in the 4-position of the pyrimidine ring. And is different from the compounds of the present invention.
On the other hand, Japan Kokai Tokyo Koho JP 07/002799 (Chemical Abstracts 122: 214102) discloses 2- (substituted phenylimino) pyrimidine derivatives having herbicidal activity and action of plant growth regulators. However, in the above publication, there is no description regarding physiological activity other than herbicidal activity of these compounds and action as a plant growth regulator, such as insecticidal, acaricidal and bactericidal activities. Further, a derivative having two trifluoromethyl groups on the phenyl ring on the 2-position imino group, or a derivative in which one or two halogen atoms are further introduced into two trifluoromethyl groups, No production examples are shown and there is no mention of their biological activity. In addition, no 2- (substituted phenylimino) pyrimidine derivatives having a nitro group as a substituent on the phenyl ring on the 2-imino group have been reported so far.
Disclosure of the invention
The problem of the present invention is that it shows a high control effect against various pests that are resistant to conventional agricultural and horticultural or clothing / living-related or livestock / pet insecticides, acaricides, nematicides, etc. It is to provide a novel pest control agent that has high safety against the above.
As a result of intensive studies to solve the above problems, the present inventors have found that a novel 2- (substituted phenylimino) pyrimidine derivative represented by the following general formula (1) is a compound having the above characteristics, The present invention has been completed.
That is, the present invention relates to the general formula (1a)
