METHOD FOR SPRAYING PEST-CONTROLLING AGENT

摘要

PROBLEM TO BE SOLVED: To develop a method for spraying a pest-controlling agent by which the pest-controlling agent such as an insecticide, an insect repellent, a germicide and a fungicide is readily and efficiently sprayed on target insect pests, fungi and the like in a limited range of a comparatively narrow range without causing problems of ignitability and environmental problem, and the efficiency on the sprayed surface is effectively sustained. SOLUTION: The method for spraying the pest-controlling agent involves spraying liquid carbon dioxide packed in a pressure-resistant container and dissolving the insecticide/insect repellent or the like through a narrow tube connected with a jetting nozzle as particle shapes of the carbon dioxide containing the insecticide/insect repellent formed by cooling the carbon dioxide gas vaporized in the narrow tube by the heat of vaporization absorbed in the narrow tube by jetting.
