稲は、我国農業における最も重要な作物であり、その病
害防除剤については、主要な稲作病害であるいもち病や
紋枯病の防除に効果のある殺菌剤が多数開発され、稲の
増収や得られるコメの品質の加養に大いに寄与している
。しかしながら、稲作病害は上記病害に限られず、一つ
の病害が防除されることにより、他の病害による減収、
品質の劣化等の問題が生じてくる。従って、稲作病害を
防除するためには多種多様の病害を防除しうるスペクト
ルの広い殺菌剤の開発が特に望まれている。Rice is the most important crop in Japan's agriculture, and many fungicides have been developed that are effective in controlling blast and sheath blight, which are major rice cultivation diseases, and are expected to increase rice yields and profits. This greatly contributes to improving the quality of rice produced. However, rice cultivation diseases are not limited to the above-mentioned diseases, and controlling one disease can reduce yield due to other diseases.
Problems such as quality deterioration arise. Therefore, in order to control rice cultivation diseases, it is particularly desired to develop a broad-spectrum fungicide that can control a wide variety of diseases.
ところで、近年新しい稲作技術、特に機械移植による栽
培技術の普及により、従来一部の地域に限られていた稲
作病害の一つである稲もみ枯細菌病が、広(全国各地で
多発し、収量が著しく減少する等の問題が生じている。By the way, in recent years, with the spread of new rice cultivation techniques, especially cultivation techniques using mechanical transplantation, rice blight blight, a rice cultivation disease that was previously limited to a few regions, has become widespread (increasingly occurring throughout the country and decreasing yields). Problems have arisen, such as a significant decrease in
この病害の防除にも、既存の多数の殺菌剤が使用されて
いるが、いずれも十分な防除効果をあげておらず、新し
い稲もみ枯細菌病防除剤が待望されている。Many existing fungicides are used to control this disease, but none of them have a sufficient control effect, and a new rice blight control agent is eagerly awaited.
本発明者らはこれらの点に鑑み、スペクトルが広く、か
つ防除が極めて困難である稲もみ枯細菌病をも防除しう
る殺菌剤の開発に鋭意検討を重ねた結果、前記の本発明
組成物が、稲もみ枯細菌病に卓効を示すのみならず、紋
枯病の防除においても優れた効果を発揮する、強力でか
つ汎用性のある殺菌組成物であることを見出し本発明に
至った。In view of these points, the present inventors have conducted intensive studies to develop a fungicide that has a broad spectrum and is capable of controlling rice bacterium blight, which is extremely difficult to control.As a result, the above-mentioned composition of the present invention However, the present inventors have discovered that it is a powerful and versatile fungicidal composition that is not only highly effective against rice blight but also in controlling sheath blight. .
本発明組成物の有効成分の一つである化合物Aは、特公
昭57−48042号公報に記載されている。浸透性植
物病害防除剤であるが、糸状菌が原因でおこる植物病害
には防除効果が劣る欠点がある。Compound A, which is one of the active ingredients of the composition of the present invention, is described in Japanese Patent Publication No. 57-48042. Although it is a systemic plant disease control agent, it has the disadvantage that it is less effective in controlling plant diseases caused by filamentous fungi.
また、もう一方の有効成分である化合物Bは稲、紋1枯
病に対する優れた殺菌剤であることが知られているが、
稲もみ枯細菌病に対しては全く防除効果を示さない。In addition, the other active ingredient, Compound B, is known to be an excellent fungicide against rice blight.
It does not show any control effect against rice blight.
本発明組成物は、上記のような作用性の異なる2種の化
合物を含有するが、稲もみ枯細菌病と稲紋枯病の両病害
を同時に防除するという単なる相補的効果を発揮するの
みならず、意外なことに両病害に優れた相乗効果をも発
揮する。The composition of the present invention contains two types of compounds with different activities as described above, but if it only exhibits a complementary effect of simultaneously controlling both rice blight and rice sheath blight. Surprisingly, it also exhibits an excellent synergistic effect against both diseases.
すなわち、各単一成分の病害防除効果からは予期できな
いほどの高い防除効果を有する。このような2種の化合

に2種病害の同時防除による効率化および経済的メリッ
トをもたらすのみならず、各成分の施用量の低下を可能
にすることにより、環境汚染等、安全面でも好ましい。That is, it has a disease control effect so high that it cannot be expected from the disease control effect of each single component. The expression of a synergistic effect by mixing two types of compound components not only brings efficiency and economic benefits through simultaneous control of two types of diseases, but also makes it possible to reduce the application amount of each component. By doing so, it is preferable in terms of safety and environmental pollution.
