本発明化合物、化合物A又は化合物Bを含有する希釈液を散布した後のアオゲイトウを温室内で栽培し、散布9日後にアオゲイトウ防除の効力を観察し、除草効果を調べた。尚、除草効果は目視で観察し、0~10の11段階で評価した(0を無作用、10を完全枯死とし、その間を1~9で評価した)。結果を[表1]に示す。
その結果、本発明化合物は、化合物A又は化合物Bより高い除草効果を示した。
プラスチックポット(φ5cm×5.5cm)に土壌を詰め、代掻きし、2日間静置した。代掻きしたポットの土壌表面に、アゼナの種子を土壌と混合して播いた。同日、ポットの土壌表面から約0.5cmの深さに催芽させたタイヌビエ種子を播いた。湛水深は約2cmに合わせた。
本発明化合物、化合物A又は化合物Bをアセトンに溶解し、蒸留水で希釈することにより、本発明化合物、化合物A又は化合物Bを含有する処理液を調製した。タイヌビエ及びアゼナを播種した同日に、本発明化合物、化合物A又は化合物Bを含有する処理液を、[表2]に記載の処理薬量になるようにポットの田面水に流し込んだ。
処理12日後に、雑草に対する除草効果を0~100の指数(0:無作用~100:完全枯殺)で目視評価した。結果を[表2]に示す。
その結果、本発明化合物は、化合物A又は化合物Bよりも高い除草効果を示した。
プラスチックチューブ(内径2.5cm×高さ10cm)に2mLの蒸留水を入れた。該蒸留水に、ジメチルスルホキシドに溶解させた本発明化合物又は化合物Aを、[表3]に記載の処理濃度になるように添加して処理液とした。次に、該処理液に催芽させたタイヌビエ種子を4粒入れた。パラフィルムでフタをした後、25℃、16時間明所、続いて25℃、8時間暗所を繰り返す条件にて栽培した。タイヌビエ種子を加えて10日後に、タイヌビエに対する除草効果を0~100の指数(0:無作用~100:完全枯殺)で目視評価した。結果を[表3]に示す。
その結果、本発明化合物は、化合物Aよりも高い除草効果を示した。
24ウェルマイクロタイタープレートの各ウェルに濾紙を敷き、蒸留水を150μL添加した。該蒸留水に、ジメチルスルホキシドに溶解した本発明化合物、化合物A又は化合物Bを、[表4]に記載の処理濃度になるように添加した。次に、各ウェルにシロイヌナズナの種子を播いた後、25℃、16時間明所、続いて25℃、8時間暗所を繰り返す条件にて栽培した。播種10日後に、シロイヌナズナに対する発芽阻害活性を0~100の指数(0:無作用~100:無発芽)で目視評価した。結果を[表4]に示す。
その結果、本発明化合物は化合物A又は化合物Bよりも高い発芽阻害活性を示した。
