Test Example 1

The plastic pot (diameter 8 cm x depth 12 cm) was filled with soil to a depth of about 8 cm. Water was poured into this pot to harrow it. This was stopped for 3 days. Echinochloa oryzicola was seeded at a depth of about 0.5 cm from the surface of the soil, and water was poured into the depth of 3 cm from the surface of the soil.

2 mg each of component (A) and pyraclonil are dissolved in 4 ml of acetone containing 2% (W / V) of Tween® (surfactant: manufactured by Nakarai Tesque Co., Ltd.), and the total amount thereof is water. It diluted to 20 ml and obtained the chemical dilution liquid.

A predetermined amount of each of the chemical dilutions was mixed with water that accumulated in the plastic pot.

Four weeks after mixing the drug dilution, the herbicidal effect on the bark was observed. The herbicidal effect was evaluated by the index of 0-100 (0: no action-100: complete kill). The results are shown in Table 1.
