The present invention is equipped with a fan that returns to the engine to generate a strong wind and a pesticide is mounted on the pesticide sprayer to spread and spray the pesticides stored in the pesticide container with the strong wind generated when the fan is rotated by the operation of the engine In this regard, the user is directly mounted on the backrest 20 so as to carry and use the blowing fan 15 that generates strong wind while rotating by driving of the engine 10 to direct the strong wind generated by the blowing fan 15. In the pesticide storage container 40 configured to inject an injector 30 for spraying the pesticide and the wind and the pesticide configured to be freely flexible, and configured to supply the pesticide to the injector 30 above the blowing fan 15, One of the pesticide storage container 40 is composed of the "n" shape like the saddle to the left and right of the engine, and the "n" shape like the saddle to the left and right of the engine. It is connected to the injector 30 at the lower end of the side to form a discharge hole 41 for coupling the pesticide supply hose 50 to supply the pesticide, to form a discharge trap 42 to be adjacent to the discharge hole 41, Suction trap 43 is formed on the inner bottom of the other side of the discharge hole 41 is not formed by connecting the discharge trap 42 and the suction trap 43 to the transfer hose 45, there is no discharge hole 41 It is configured to discharge the pesticides in the pesticide storage container 40 on the side to the discharge hole 41 formed on the other side.본 고안은 강한 바람을 발생하기 위하여 엔진으로 돌아가는 팬이 탑재되고 그 위에 농약통이 탑재되어서 상기 엔진의 가동으로 팬이 돌아가면서 발생하는 강한 바람으로 농약통에 저장된 농약을 농작물에 확산 살포하는 농약살포기에 관한 것으로, 엔진(10)의 구동으로 회동하면서 강한 바람을 일으키는 송풍팬(15)을 사용자가 직접 짊어지고 사용하도록 등받이(20)에 장착하여 상기 송풍팬(15)에서 발생하는 강한 바람을 방향 선택이 자유롭게 플렉시블하게 구성한 바람과 농약을 분사하는 분사기(30)를 구성하고, 상기 송풍팬(15) 상측에 분사기(30)에 농약을 공급하는 농약저장통(40)을 구성한 것에 있어서, 상기 농약저장통(40)을 엔진의 좌,우로 말안장처럼 "n"자형으로 구성하고, 상기 엔진의 좌,우로 말안장처럼 "n"자형으로 구성한 농약저장통(40)의 어느 한
