【発明の属する技術分野】
本発明は、植物病害防除組成物に関する。
【0002】
【従来の技術および発明が解決しようとする課題】
ある種のピラゾリノン誘導体が植物病害防除効力を有することが知られている(特開平8−208621号公報、特開2000−226374号公報、特開2001−11053号公報等)。一方、同時期に複数の病害が発生する場合や市販剤の耐性菌問題など、1種の有効成分だけではその防除効果が不十分となる為、2種以上の植物病害防除剤を同時期に植物に施用することも実際に行われている。本発明は、2種以上の有効成分を含有する高活性な植物病害防除組成物を提供することを課題とする。
【0003】
【課題を解決するための手段】
かかる状況下、本発明者は植物病害防除効力について鋭意検討した結果、ある種のピラゾリノン誘導体と特定の化合物とを併用することにより、植物病害防除において、高い効果が見出されることを見出し、本発明に至った。
即ち本発明は、3−クロロ−N−(3−クロロ−5−トリフルオロメチル−2−ピリジル)−α,α,α−トリフルオロ−2,6−ジニトロ−p−トルイジン〔以下、化合物Aと記す〕、4−(2,2−ジフルオロ−1,3−ベンゾジオキソール−4−イル)−1H−ピロール−3−カルボニトリル〔以下、化合物Bと記す〕、N−(4,6−ジメチルピリミジン−2−イル)アニリン〔以下、化合物Cと記す〕、4−シクロプロピル−6−メチル−N−フェニル−2−ピリミジンアミン〔以下、化合物Dと記す〕、N−(4−メチル−6−プロプ−1−イニルピリミジン−2−イル)アニリン〔以下、化合物Eと記す〕、1−メチルエチル=(3,4−ジエトキシフェニル)カーバメート〔以下、化合物Fと記す〕、N−(3,5−ジクロロフェニル)−1,2−ジメチルシクロプロパン−1,2−ジカルボキシイミド〔以下、化合物Gと記す〕、3−(3,5−ジクロロフェニル)−N−(1−メチルエチル)−2,4−ジオキソ−1−イミダゾリジンカルボキサミド〔以下、化合物Hと記す〕、3−(3,5−ジクロロフェニル)−5−エテニル−5−メチル−1,3−オキサゾリジン−2,4−ジオン〔以下、化合物Iと記す〕、N−〔2−(1,3−ジメチルブチル)−3−チエニル〕−2,4−ジメチルチアゾール−5−カルボキサミド〔以下、化合物Jと記す〕、N−〔2−(1,3−ジメチルブチル)−3−チエニル〕−3−トリフルオロメチル−1−メチルピラゾール−4−カルボキサミド〔以下、化合物Kと記す〕および2−クロロ−N−〔4’−クロロ−(1,1’−ビフェニル)−2−イル〕−3−ピリジンカルボキサミド〔以下、化合物Lと記す〕から選ばれる少なくとも1種と、
