The crop 12 sways due to wind or the like and has a predetermined movement speed. The pest 28 flies around in the air at a high speed and has a movement speed that is clearly distinguishable from the movement speed of the crop 12. The situation of the crop 12 and the pest 28 is monitored by the video camera 10 over the entire range of the crop 12, and the moving body identification means 32 of the computer 14 moves the image from the video camera 10 by image processing based on the speed. The presence or absence of the body is identified. When the pest 28 is generated, the presence of the moving body is recognized, and the driving means 34 causes the chemical solution 18 from the nozzle 26 at the place where the pest 28 as the moving body is found through the opening / closing control of the electromagnetic opening / closing valve 24. Squirt out. Thus, the pest 28 receives the drug solution 18 and is exterminated.

In the invention of claim 2, in identifying the pests from the image obtained from the visual monitoring means, attention is paid to the fact that the pests are moving at a speed sufficiently fast with respect to the movement of the crop or the like caused by wind or the like. The presence or absence of a pest is detected by detecting a moving body by image processing of video based on speed. Therefore, even when the pest has a protective color or has various shapes, the presence or absence of the pest can be efficiently detected.
Furthermore, since image processing by speed does not require a color image, an inexpensive black and white camera can be adopted for monitoring.
