Abstract
Description
この発明は、農園芸用薬剤に関し、さらに詳しくは、高い安全性を有し、植物に対する付着性と耐雨性とに優れ、しかも長い有効期間を維持することのできる殺菌剤、殺虫剤または除草剤等の農園芸用薬剤に関する。 The present invention relates to an agricultural and horticultural agent, and more specifically, a fungicide, insecticide or herbicide which has high safety, excellent adhesion to plants and rain resistance, and can maintain a long effective period. It relates to agricultural and horticultural drugs such as
これまでに、多数の農園芸用防除剤が開発されると共に、これら農園芸用防除剤の剤型化についても、多様な開発がなされてきた。この多様な剤型化の背景には、薬剤処理の簡略化、人畜に対する急性毒性や刺激性の軽減、海洋または河川に生息する生物に対する毒性の軽減等、人畜および環境に対する保全、農園芸用防除剤における有効成分の残効性の向上、薬害の軽減等が強く要望されるようになってきた状況がある。 So far, a large number of agricultural and horticultural control agents have been developed, and various developments have been made to formulate these agricultural and horticultural control agents. The background to this variety of dosage forms is the protection of humans and the environment, such as simplification of chemical treatment, reduction of acute toxicity and irritation to human animals, reduction of toxicity to organisms inhabiting the ocean or rivers, pest control There is a situation in which there is a strong demand for improvement of the residual effect of active ingredients and reduction of phytotoxicity.
近年、環境に対する意識は一層高まり、特に農薬の安全性については関心が高く、注目の的となっている。このような時流の中、開発されている農薬の剤型の態様は、ますます人畜および環境に対する保全を目的とする傾向を強め、マイクロカプセル化剤、フロアブル化剤等の剤型による改善が多数試みられている。 In recent years, awareness of the environment has further increased, and in particular, the safety of pesticides has attracted attention and has attracted attention. Amid these trends, the agrochemical dosage forms that are being developed are increasingly becoming more and more protected for human and environmental conservation, and there are many improvements due to dosage forms such as microencapsulating agents and flowable agents. Has been tried.
しかしながら、これら剤型のみによる改善では満足すべき効果を奏することができないことから、農園芸用防除剤の有効成分に着目して、低薬量で広範な適用を可能とする化合物を選択することによって、薬剤処理の簡略化、人畜および環境に対する負荷の低減を図る方向に向かっている。 However, since improvement with only these dosage forms cannot produce a satisfactory effect, paying attention to the active ingredients of agricultural and horticultural control agents, selecting compounds that can be widely applied at low doses Therefore, we are moving toward the simplification of chemical treatment and the reduction of the burden on humans and the environment.
ところが、農園芸用防除剤の有効成分の開発には、多大な労力、時間および経費を要するため、最近は、安全性と効力とが認められている既存の有効成分が見直され、剤型の変更等による改善が行われている。しかし、この剤型の変更等によっては、ある程度の改善効果は認められるものの、人畜および環境に対する負荷については、従来とほとんど変わるところはない。 However, the development of active ingredients for agricultural and horticultural control agents requires a great deal of labor, time and expense. Recently, existing active ingredients that have been recognized as safe and effective have been reviewed, Improvements have been made through changes. However, although a certain degree of improvement effect is recognized depending on the change of the dosage form, etc., there is almost no difference with respect to human livestock and the environment.
また、有効成分の効力増強を企図した展着剤の開発も多く試みられるようになってきた。しかし、この展着剤に用いられる界面活性剤は、薬剤付着性および浸透性のいずれか一方を改善する効果は見られるが、双方を改善し、効力増強を図る展着剤は少なく、この場合も人畜および環境に対する負荷については、十分な改善が図られていない。 In addition, many attempts have been made to develop a spreading agent intended to increase the efficacy of active ingredients. However, the surfactant used in this spreading agent has an effect of improving either drug adhesion or permeability, but there are few spreading agents that improve both and enhance efficacy. However, sufficient impact on human livestock and the environment has not been achieved.
さらに、展着剤の多くは高い安全性を有するが、各成分中には、環境ホルモンとして注目されている成分を含むものもある等の問題もあった。また、安全性の高い機械油または植物油等を展着剤として用いることにより、効力増強を図ることができることも認められているが、植物体に対する薬害等によって使用の制限を受け、広く実用化されていない現状である。 Furthermore, many of the spreading agents have high safety, but there are problems such as that some of the components include components that are attracting attention as environmental hormones. In addition, it has been recognized that the use of highly safe machine oil or vegetable oil as a spreading agent can increase the efficacy, but it has been widely put into practical use due to its use restrictions due to phytotoxicity to plants. The current situation is not.
これまでに、植物系油を配合した農園芸用殺菌剤組成物として、８−オキシキノリン銅と植物系油とから成る農園芸用殺菌剤組成物が知られている（特許文献１参照）。この農園芸用殺菌剤組成物においては、８−オキシキノリン銅の効力増強はある程度認められるが、剤型の形態によって効果が変動することがあり、また、その効果は剤型に起因するものなのか、植物系油に起因するものなのか判然としないところがあった。
この発明は、このような現状に鑑み、剤型および有効成分に拘束されることなく、高い安全性を有し、植物に対する付着性と耐雨性とに優れ、しかも長い有効期間を維持することのできる殺菌剤、殺虫剤または除草剤等の農園芸用薬剤を提供することをその課題とする。 In view of such a current situation, the present invention has high safety without being restricted by the dosage form and active ingredients, has excellent adhesion to plants and rain resistance, and maintains a long effective period.
