Since the present invention further comprises an air discharger communicating with the inside of the medicine container at the top of the medicine container, the air discharged from the inside of the medicine container expanded during agitation of pesticides or fertilizers by a strong blowing flow introduced by the driving force of the engine. It can be easily discharged through the agitation of the pesticide or fertilizer by the blowing force of the engine without opening the lid, and the pesticide equipped with an air discharger to prevent the pesticide or fertilizer from being discharged out of the medicine container when stirring And to provide a fertilizer spreader. To this end, the present invention, the engine 11 is configured at the bottom, the lid 12 is configured on the upper surface and the medicine container 13 containing the pesticide or fertilizer is configured on the upper portion of the engine 11 and the engine 11 The strong blowing force generated by the driving force of the engine 11 so as to introduce a strong blowing force generated by the driving force of the engine 11 and the spray pipe 14 is sprayed with a strong blowing force generated by the driving force of the engine (13). In the pesticide and fertilizer spreader consisting of a connecting tube (15) connecting the interior of the medicine cabinet (11), the connection pipe 15 to the inner side of the medicine cabinet (13) on the upper outside of the medicine cabinet (13) When the strong blowing air of the engine 11 is introduced through the expansion of the inside of the medicine cabinet 13), the air discharger 20 for discharging the air inside the medicine cabinet 13 out of the medicine cabinet 13 is further configured Characterized in that it is made. The air discharger 20, the discharge pipe 21 is configured to be perpendicular to the upper surface of the medicine cabinet (13) and communicate with the inside of the medicine cabinet (13)； An opening and closing portion 22 connected to the
