Study of the Sesamia cretica Population Control Using Fibronil Insecticide in Sugarcane Fields of Khuzestan Province Amir Khadempour1, Amir Soraghi1, Fakher Kardoni1*, Shabnam Ashouri2 1- Debal Khazaei Sugarcane Agro-Industry, Khuzestan Province, Iran 2- Nuclear Agriculture Research School, Nuclear Science and Technology Research Institute, Karaj, Iran *Corresponding author: Email: [e-mail] Received: 10 March 2022 Accepted: 20 June 2022 Abstract One of the most important pests of sugarcane in Iran is the stem borer, which causes great damage to the amount of sugarcane production every year. Therefore, controlling this pest using insecticides is very important. This experiment was conducted with the aim of investigating the effect of fipronil formulation on sugarcane Sesamia cretica control. The experiment was carried out in the research fields of the Debal KhazaeiSugarcane Agro-Industry, Khuzestan Province of Iran, in 2021. The experiment treatments included fipronil 20 kg ha-1 (0.2% G), 1 and 1.5 l ha-1 (SC 5%) along with controls in two cultivars CP69 and CP48. The experiment results showed that there was a significant difference in the percentage of dead central buds with the use of fipronil in the form of granules and suspension compared to the control. The percentage of dead central bud in CP69 cultivar with the application of fipronil 20 kg ha-1 (0.2% G) and 1 and 1.5 l ha-1 (SC 5%) was reduced by 26, 34 and 32% compared to the control, respectively. Also, in the CP48 cultivar, the percentage of central bud decreased by 20, 23 and 24% compared to the control, respectively, with the application of fipronil 20 kg ha-1 (0.2% G) and 1 and 1.5 l ha-1 (SC 5%). The number of live larvae in both cultivars in 1 and 1.5 l ha-1 SC was lower than other treatments. Also, the results of poisons efficiency showed that in both cultivars, the highest efficiency of poison was observed in fipronil SC 5% of 1 and 1.5 l ha-1. In general, due to the lack of difference between 1 and 1.5 l ha-1 SC, it is recommended to use fipronil 1 l ha-1 to control of sugarcane Sesamia.
