Under an indoor windless environment with a temperature of 21 ° C and a humidity of 40%, a sample (feeling) was applied to an acrylic plate (manufactured by Hikari Co., Ltd., 160 mm x 180 mm) at positions 1 to 6 of the 0.5 m x 1.0 m section shown in FIG. Water paper or cut plant leaves) were attached one by one with double-sided tape, fixed to the floor, and the head of the sprayed article was pushed at a height of 2 m above each center point divided into eight equal parts.
  • the total discharge amount is 0.5 mL with 8 pushes, which corresponds to 1.0 L / 10a.
  • the surface of the sample was observed with a digital microscope (“VHX-1000”, manufactured by KEYENCE CORPORATION), the area of the discolored part was determined, and the average value of 6 places was taken as the coverage (%).
  • the area of the portion of the water-sensitive paper that changed color from yellow to blue was defined as the area of the portion of the leaf that was colored white, and the area of the portion that was colored white was used as the covered area.
  • Water-sensitive test paper (model number 20131-1N, 76 mm x 26 mm, manufactured by Spraying Systems Co.)
  • Plant leaves Rice (Koshihikari, tillering stage) leaves (contact angle with water 141 °)
  • Example 1 and Comparative Example 1> Using the pesticide composition shown in Table 2, the coverage of water-sensitive paper and plant leaves was determined. From Table 2, in any of the pesticides, the pesticide composition using the component (A) has a higher coverage of the water-sensitive paper than the blank containing the component (A), and evaporation can be suppressed. I understand. In addition, it can be seen that the improved coverage also improved the coverage of the leaf surface of the plant, the pesticides became wet and spread after coating, and the spread area on the leaf surface also increased.
  • Example 2 and Comparative Example 2> Using the pesticide composition shown in Table 3, the coverage of water-sensitive paper and plant leaves was determined. From Table 3, it can be seen that the pesticide composition using the component (A) has a higher coverage of the water-sensitive paper than the blank containing the component (A) and can suppress evaporation. In addition, it can be seen that the improved coverage also improved the coverage of the leaf surface of the plant, the pesticides became wet and spread after coating, and the spread area on the leaf surface also increased.
  • Example 3 and Comparative Example 3> Using the pesticide composition shown in Table 4, the coverage of water-sensitive paper and plant leaves was determined. From Table 4, it can be seen that the pesticide composition using the component (A) has a higher coverage of the water-sensitive paper than the blank containing the component (A) and can suppress evaporation. In addition, it can be seen that the improved coverage also improved the coverage of the leaf surface of the plant, the pesticides became wet and spread after coating, and the spread area on the leaf surface also increased. Further, it can be seen that the coverage is further improved by using the component (B) or the component (B) and the component (C) in combination.
  • Example 4 and Comparative Example 4> Using the pesticide composition shown in Table 5, the coverage of water-sensitive paper and plant leaves was determined. From Table 5, it can be seen that the pesticide composition using the component (A) has a higher coverage of the water-sensitive paper than the blank containing the component (A) and can suppress evaporation. In addition, it can be seen that the improved coverage also improved the coverage of the leaf surface of the plant, the pesticides became wet and spread after coating, and the spread area on the leaf surface also increased.
  • Example 5 and Comparative Example 5> Using the pesticide composition shown in Table 6, the coverage of the water-sensitive paper was determined. From Table 6, it can be seen that the pesticide composition using the component (A) has a higher coverage of the water-sensitive paper than the blank containing the component (A) and can suppress evaporation.
  • Example 6 and Comparative Example 6> Using the pesticide composition shown in Table 7, the coverage of the water-sensitive paper was determined. From Table 7, the pesticide composition using the pesticide efficacy enhancer composition containing the component (A) is more water sensitive than the blank without the pesticide efficacy enhancer composition regardless of which pesticide is used. It can be seen that the coverage of the paper is high and evaporation can be suppressed.
  • Example 7 and Comparative Example 7> Using the pesticide composition shown in Table 8, the coverage of the water-sensitive paper was determined. The results are shown in Table 8.
  • the pesticide composition in Table 8 corresponds to the treatment liquid applied to the plant. From Table 8, the pesticide composition using the pesticide efficacy enhancer composition containing the component (A) uses the pesticide efficacy enhancer composition not containing the component (A) regardless of which pesticide is used. It can be seen that the coverage of the water-sensitive paper is higher than that of the blank, and evaporation can be suppressed.
  • Example 8 and Comparative Example 8 ⁇ Coverage measurement method 2> Each pesticide composition was filled in a tank of a pesticide spraying drone (using "AGRAS MG-1", model TX-VK8 nozzle manufactured by Daiki Innovation Technology Co., Ltd. (DJI), and Spraying Systems Co.) at 1.6 kg. Outdoors, at positions 1 to 12 of the 16 m ⁇ 8 m section shown in FIG. 2, a sample (cut plant leaf) is attached to an acrylic plate (manufactured by Hikari Co., Ltd., 160 mm ⁇ 180 mm) one by one with double-sided tape. Attached and fixed to the ground. The sections of FIG.
  • the pesticide composition was sprayed in this order from top to bottom in the center of the plot.
  • the spraying conditions are a spraying altitude of 2 m, a discharge rate of 800 mL / min, a flight speed of 15 km / hour, and a spraying amount of the pesticide composition corresponding to 0.8 L / 10 a.
  • the pesticide composition shown in Table 9 was prepared using the above components. Using the obtained pesticide composition, the coverage with respect to the object was measured by the above method. Coverage was also shown relative to the blank in each test group. The results are shown in Table 9.
  • the pesticide composition in Table 9 corresponds to the treatment liquid applied to the plant. From Table 9, the pesticide composition using the pesticide efficacy enhancer composition containing the component (A) has a higher coverage rate on the leaf surface of the plant than the blank without the pesticide efficacy enhancer composition. It can be seen that evaporation can be suppressed.
