Common pistachio psylla, is a native pest in pistachio orchards of Iran. In this research, the LC50 and LC90 values of Movento, Sivanto, Starkel and Diabon pesticides were obtained on the nymphs of this pest in laboratory conditions. Then it was used against the pest in field conditions along with water spray treatment and potassium silicate liquid fertilizer. Finally, the mortality of nymphs was calculated 3, 7, 14 and 21 days after spraying. The field data were statistically analyzed as a factorial experiment based on a randomized complete block design in three replications with two factors of treatment and effect time. The values of LC50 and LC90 of insecticides in bioassay tests are respectively for Movento 500.78 and 1933.88, for Diabon 7259.57 and19839.41, for Sivanto 59.85 and 193.16 and for Starkel 7.19 and 36.96 µl/l were estimated. The results of the field test showed that the highest pest mortality on the third day after spraying were related to Diabon, Starkel, Sivanto insecticides, potassium silicate fertilizer, water spray and Movento pesticide, respectively equal to 81.33, 70.66., 57.33, 56.00, 48.00 and 45.66%. On the 14th day, the mortality rate in Movento treatment reached 84% and was significantly higher than other treatments. Therefore, the toxicity and durability of Diabon and Movento are more than other treatments. Based on the results of this research, Diabon pesticide, potassium silicate fertilizer and water spray due to its compatibility with the environment and Movento insecticide due to its durability It is suitable to control this pest.
