In this case, the distance between the left and right branches and leaves is different depending on the length of the stem and the branches, so that the branching angle of each flexible branch material depends on the flexibility of the branch material itself according to the distance between the branches and leaves that differ depending on the length. Appropriately selected, each jet nozzle is set to a distance suitable for spraying the chemical liquid with respect to the branches and leaves.

Also, when the distance between the left and right branches and leaves becomes narrower as the crop grows, the flexible branch material is bent in a direction close to vertical, or the flexible branch materials are bent so as to intersect with each other. Set the ejection nozzle of to the same position as the column.

When the flexible branch members are bent so as to intersect with each other according to the growth of such crops, in this pest controller, the branch members bent in a U shape are fixed by a stopper plate and a U-shaped bolt. Since the branch material is diverged from the support column directly in the left-right direction, the branch material can be freely bent between the diverged portion of the support column and the tip portion.

Further, in the case of spraying a chemical solution on agricultural products with a low stem height, loosen the stoppers of the respective flexible branch members fixed to the support, and replace them at appropriate length positions along the support before use.
