Abstract:   (330 Views)
Increasing insect resistance to the high toxicity of organophosphates and other conventional insecticides highlights the importance of developing and identifying alternative chemicals to successfully manage insect pests, including the striped rice stem borer (SRSB) Chilo suppressalis (Walker). SRSB is one of the most serious pests in paddy fields worldwide, especially in northern Iran. The present study was conducted to determine the efficiency of six insecticides viz., diazinon 10 G (Bazodin) 15 kg/ha; fipronil 0.2 G (Regent) 20 kg/ha; chlorantraniliprole 0.4 G (Ferterra) 12.5 kg/ha; thiamethoxam 25 WG (Actara) 0.2 kg/ha; flubendiamide 20 WG (Takumi) 0.9 kg/ha; dinotefuran 20 SG (Starkle) 0.75 kg/ha against SRSB. The experiments were carried out in randomized complete block design with three replications in experimental paddy fields of Rice Research Institute of Iran, Guilan province, 2018 and 2019. Chlorantraniliprole had the lowest dead heart and whitehead percent and the greatest efficiency against SRSB, followed by flubendiamide and dinotefuran. Our results suggested that chlorantraniliprole, flubendiamide, and dinotefuran can replace diazinon and fipronil in paddy fields. Furthermore, a new equation has been proposed for the calculation efficiency of insecticides based on the SRSB damage percent.
