As an alternative for pesticide, we have developed a new control technique using ultrasonic wave as a physical stimulus. Ultrasonic waves of about 120 dB and 40 kHz, can significantly reduce the damage caused by noctuids such as Eudocima tyrannus which is a common pest of fruit trees. Furthermore, irradiation of seedlings of rice, tomato and strawberry with ultrasonic waves can control diseases induced by rice blast, wilting tomato and strawberry mildew and hence it is expected as an efficient environment-friendly pest control technology.
