Efficacy of abamectin, spinosad, thiodicarb and fenoxycarb+lufnurun in control of rose plume moth, Eucnaemidophorus rhododactylus (Lep. Pterophoridae)

Eucnaemidophorus rhododactylus Denis & Schiff. is one of the most important pests of Damask rose in Iran, where chemical insecticide application is the common approach to control. In this study, efficacy of abamectin, spinosad, thiodicarb, and fenoxycarb+lufnurun was evaluated in four replications in spring of 2018 and 2019 in Lyzangan, Darab, Iran, through a randomized block design. The number of infested buds in each plant and the number of infested plants in each plot were the comparison indices of insecticides efficiency. There was a significant difference between measured indices of two years. Based on the number of infested buds, the entire treatments were grouped in two levels for both years; however, in the years of 2018 and 2019, they were placed in two and three levels, respectively. Based on the percentages of infested buds, abamectin and other treatments were significantly different within two years. According to this study, abamectin was not evaluated as an effective insecticide for controlling the rose plume moth.
