Also, another tube prepared in the same manner is used to plant tubers of Urikawa, Omodaka, Hirumushiro, Mitsugayatsuri, Koukiyara, Krogwai and Shizui, and transplant 2-4 leaves of rice at a depth of 2-3 cm. Place each pot in a greenhouse to grow weeds and rice.
Immediately after transplanting rice, 7 days after transplanting, 14 days after transplanting, or 21 days after transplanting, one of the combinations of Compound B and Compound C shown in Table 1 is cultivated with weeds and rice, respectively. Process the pot as follows.
A herbicide spray solution containing Compound B and Compound C is prepared so that the dose when treated is the value shown in Table 1. The herbicide spray solution is prepared according to the following procedure. A predetermined amount of each of Compound B and Compound C is dissolved in acetone containing 2% (w / v) of Tween 20 to obtain an acetone solution of Compound B and an acetone solution of Compound C, respectively. Each acetone solution is diluted with water so that the acetone concentration becomes 10% by volume to obtain a water dilution of compound B and a water dilution of compound C, respectively. Subsequently, the herbicide spraying liquid containing the compound B and the compound C is obtained by mixing the water dilution of the compound B and the water dilution of the compound C. The pot is submerged to 3 to 5 cm, and the herbicide spray solution is dropped onto the water surface.
As a result, the combination of Compound B and Compound C shown in Table 1 has a high herbicidal effect (synergistic effect) on weeds without causing any practically harmful harm to rice in any combination. can get.

  By the method of the present invention, a method for effectively controlling weeds in paddy rice cultivation was obtained.
