In this paper, five pesticides with different mechanisms were conducted against Panonychus ulmi through field trail. The results showed that 20% azocyclotin SC and 5% fenpy- roximate SC had significant effect on P. ulmi with the control efficacy over 90% at second day and 25th day after the treaments. 99% petroleum oil EC and 1.8% abamectin EC also had good effects on P. ulmi, these two pesticides had an effective period of more than 25 days in the fields. 20% azocyclotin SC and 5% fenpyroximate SC could control P. ulmi timely and effectively and were safe on natural enemies and crops. Therefore, they were worth to select priority in the field use.
