 本発明組成物の有用性を以下の試験例において具体的に説明する。 The usefulness of the composition of the present invention will be specifically described in the following test examples.
 式(1)で表される化合物の1種以上と、化合物群Bから選ばれる1種以上を併用した場合に、単独の効果から期待される効果を上回る効果を奏することを以下の試験例で示す。 In the following test examples, when one or more compounds represented by the formula (1) and one or more compounds selected from the compound group B are used in combination, the effects that exceed the effects expected from a single effect are exhibited. Show.
 2種類の除草活性成分を併用した場合の相乗的除草効果については、次のように説明することができる。すなわち個々の活性成分はその除草活性にそれぞれ欠点を示す場合が多くあるが、その場合2種の活性成分を組み合わせた除草活性が、その2種の活性成分の各々の活性の単純な合計(期待される活性)よりも大きくなる場合にこれを相乗作用という。2種の活性成分の組み合わせにより期待される活性は次のように計算することができる(Colby S.R.、除草剤の組み合わせの相乗および拮抗作用反応の計算、WEED第15巻、20―22巻(1967)参照)。
 C=α+β―(α・β/100)
  α:除草剤Aをakg/haの量で処理したときの抑制率
  β:除草剤Bをbkg/haの量で処理したときの抑制率
  C:除草剤Aをakg/ha、除草剤Bをbkg/haの量で処理した場合に期待される抑制率
 即ち、実際の抑制率が上記計算値よりも大きいならば相乗的、同じならば相加的ということができる。
The synergistic herbicidal effect when two kinds of herbicidal active ingredients are used in combination can be explained as follows. In other words, individual active ingredients often have drawbacks in their herbicidal activity. In this case, the herbicidal activity combining the two active ingredients is a simple sum of the activities of each of the two active ingredients (expectation). This is called synergy when the activity is greater than The expected activity of the combination of the two active ingredients can be calculated as follows (Colby SR, calculation of synergistic and antagonistic responses of herbicide combinations, WEED Vol. 15, 20-22 Vol. (1967)).
C = α + β- (α · β / 100)
α: Inhibition rate when herbicide A is treated in an amount of akg / ha β: Inhibition rate when herbicide B is treated in an amount of bkg / ha C: Herbicide A is akg / ha, herbicide B is Inhibition rate expected when processing at the amount of bkg / ha That is, it can be said that if the actual inhibition rate is larger than the calculated value, it is synergistic, and if it is the same, it is additive.

Five days later, seeds of black firefly or tuber of Omodaka were sown or transplanted, and treated on the 10th day after sowing with a predetermined amount of the reagent prepared according to the formulation example. After 20 days of the drug treatment, the effects on dog firefly, rice bran and rice were examined according to the criteria of 0 = no effect or 100 = complete killing by observational evaluation. The results are shown in Tables 3 and 4.
