The present invention relates to a method for electrostatically dispersing a drug by forming a cloud of charged particles and making it possible to efficiently attach the drug to a target object using the charged particle cloud.

で今−歩の改善が必要であった。According to this method, it is possible to spray the drug on the target object much more efficiently than with the conventional electrostatic spraying method, but since each charged suspended particle is scattered, it is difficult to spray the drug on the target object. It is difficult to generate a strong electric field between the particles and the target object, so due to the image effect, each particle will stick only when it comes very close to the target object.In other words, it will not stick unless it is very close. Immediate improvements were needed in terms of drug adhesion efficiency.

煙粒子を吹き込むことによって行われる。"Means for Solving the Problems" The present invention forms a charged particle cloud by charging smoke particles of a smoke agent containing a drug with an electric field, and forms a charged particle cloud in a closed environment with the charged particle cloud. "Action" is a method of electrostatic dispersion of a drug, which is characterized by adhering the drug by electrostatic force generated between target objects. Particles are charged by passing them through a cylindrical body with an electrode in the center, and the charged particles are blown into a closed environment such as an agricultural or horticultural facility, a so-called house, using a blower, or
Alternatively, electrodes are installed in a closed environment such as a house, and smoke particles of a smoke agent are blown into the air.
上記の方法によって帯電した燻煙剤の煙粒子は、密閉環

The adhesion efficiency is further improved.

Since the speed is slow and the target object is enveloped for a long period of time, a large amount of fine particles can reliably adhere to the front and back surfaces of the target object, thereby further improving the adhesion efficiency of the drug to the target object. be.
