Hereinafter, the present invention will be described with reference to examples.
However, it goes without saying that the present invention is not limited to these examples. Table 1 below shows the formulation of the aerosol used in each example.

[0027]

[Table 1]

Further, the insecticidal aerosol for trees is as follows. The area of the stem hole 11 in the ejection part 2 of the aerosol can 1 is set to 1.50 mm ² . The area of the vapor tap hole 14 is 0.164 mm ²
And The area of the housing hole 15 is set to 1.886 mm ² . The nozzle diameter is 1.5 mm (1.766 mm ² ). The outer edge of the actuator pressing portion 12 is located 2 mm outside the mounting cup 4 in the aerosol can 1. The ejection amount of the aerosol agent at 25 ° C. for 10 seconds is 50 g (50 g / 10 seconds (25 ° C.)).

<Embodiment 1> In Embodiment 1, the nozzle 1 of the ejection part 2 is used.
0 The distance from the tip to the ceiling (upward) is 1m, 2m,
Grapes of 3 m and 4 m were used, and using a naturally occurring grape croaker, 10 animals each were placed and tested for insecticidal efficacy at each distance. The results are shown in Table 2 below.

[0030]

[Table 2]

As is clear from Table 2, the insecticidal efficacy was 1
It is 100% for m, 2m and 3m, and 60% for 4m, indicating that the aerosol can be ejected far.

<Embodiment 2> In Embodiment 2, an insecticide-killing aerosol for trees in which the jetting direction of the jetting part 2 is the same as the axial direction of the aerosol can 1, and the jetting direction is orthogonal to the axial direction of the aerosol can 1. Using a tree-oriented insecticide-sterilized aerosol oriented in the horizontal direction
The aerosol agent was ejected to the nozzle, and the remaining amount of the aerosol agent at the time when the propellant of the aerosol agent disappeared was measured.
This measurement was repeated 10 times. The results are shown in Table 3 below.

[0033]

[Table 3]

As is apparent from Table 3, when the jetting direction is the same as the axial direction of the aerosol can 1, the jetting direction is a direction (horizontal direction) orthogonal to the axial direction of the aerosol can 1.
It can be seen that the liquid residue of the aerosol agent in the aerosol can 1 is significantly smaller than that of the above-described case.

<Embodiment 3> In Embodiment 3, as shown in FIG. 3 (A), the jetting direction of the jetting portion 2 is set to the same direction as the axial direction of the aerosol can 1 by using an insecticide-killing aerosol for trees. Top direction (upward) from the tip of the nozzle 10 of the part 2
The distance to the trees is 1m, 2m, 3m, and 4m, and 6 of them are artificially attached to the backside of the leaves of cherry using Aoilaga naturally occurring in cherry. The test was performed. The results are shown in Table 4 below.

[0036]

[Table 4]

As a comparative symmetry, as shown in FIG. 3 (B), the injection is performed by using an insecticide-killing aerosol for trees in which the ejection direction at the ejection portion 2 is perpendicular to the axial direction of the aerosol can 1 (horizontal direction). The distance in the horizontal direction (lateral direction) from the tip of the orifice 10 of the part 2 is 1 m, 2 m, 3 m, 4 m, and using artificially generated Aoiraga on the cherry tree, 6 heads are artificially placed behind the leaves of the cherry tree The insecticidal efficacy at each distance was tested. The results are shown in Table 5 below.

[0038]

[Table 5]

As is clear from Tables 4 and 5, the jetting direction set in the same direction as the axial direction of the aerosol can 1 is as follows.
It can be seen that the insecticidal effect is high, especially when the jetting direction is set in a direction (horizontal direction) perpendicular to the axial direction of the aerosol can 1, particularly in a distant place.

Example 4 In Example 4, the load applied to the actuator pressing portion 12 of the ejection portion 2 of the aerosol can 1 was measured using a tensile tester (manufactured by Shimadzu Corporation). In addition, the same measurement was performed for a comparative example in which the outer edge of the actuator pressing portion 12 was positioned 2 mm inside the mounting cup 4 in the aerosol can 1. The results are shown in Table 6 below.

[0041]

[Table 6]

As is clear from Table 6, when the outer edge of the actuator pressing portion 12 is located outside the mounting cup 4, the load pressure (the force pressing the actuator pressing portion 12) is higher than that located inside. It turns out to be small.

As described above, conventionally, the arrow B in FIG.
As shown in the figure, the jetting direction was a horizontal direction orthogonal to the axial direction of the aerosol can 1, and it was difficult to spray the aerosol agent effectively on the back side of the leaves and the like. Since the jetting direction of the jetting portion 2 is set to the same direction as the axial direction of the aerosol can 1, the spraying is performed on a tree at a high place where a human cannot reach, as shown by an arrow A in FIG. 4. At this time, the insecticide-killing aerosol for trees can be spouted upward without laying it down, and the aerosol can be easily and well sprayed. Further, the aerosol can be effectively sprayed on the back side of the leaves and the like.

[0044]

According to the present invention, the spraying direction at the spraying part is the same as the axial direction of the aerosol can. It can be ejected upward without performing, and the aerosol can be easily and satisfactorily sprayed while reducing the liquid residue of the aerosol in the aerosol can. Further, the aerosol can be effectively sprayed on the back side of the leaves and the like. Thereby, the tree is efficiently sprayed with the aerosol agent for insecticide sterilization for the tree, and the workability of the spraying operation is significantly improved.

The aerosol formulation contains at least one compound selected from the group consisting of water and alcohols as a diluent, thereby reducing the phytotoxicity to plants. Further, by setting the ejection amount to 20 to 100 g / 10 seconds (25 ° C.), a large amount of aerosol can be ejected, and the pests can be surely exterminated.

The volume ratio between the liquid and the gas composition of the aerosol is set to 40:60 to 90:10, so that the jetting pressure is increased so that the aerosol can be jetted far away, so that the aerosol can be ejected to a high place of a tree. The spraying operation can be performed well.

By setting the ejection port diameter of the ejection portion to 0.7 to 3.0 mm, a large amount of aerosol can be ejected satisfactorily, and efficient spraying of the aerosol can be performed.

The area of the stem hole in the ejection part is set to 0.5 to
2.0mm ² , Vapor tap hole area is 0 ~ 0.5m
By setting m ² and the area of the housing hole to be 1.0 to 3.0 mm ² , the aerosol can be ejected in an optimal state, thereby enabling efficient spraying of the aerosol.

Since the outer edge of the actuator pressing portion of the jetting portion is located outside the mounting cup in the aerosol can, the force for pressing the actuator pressing portion is reduced, and particularly, the fingertip when jetting the aerosol agent for a longer time is reduced. The load can be reduced, and the work is facilitated.
