Comparsion of Efficacies of the Insecticides tebufenoside (SC 20%), emmamectin benzoate (SG 5%), indoxacarb (EC 15%) and fipronil+hexaflumuron (EC 5%) against Agrotis segetum Schiff

The cutworms (Agrotis spp.) are cosmopolitan polyphagous pests and cause damage to a variety of crops including chickpea. In this study, the efficacies of some safe insecticides on chickpea cutworms, Agrotis segetum (Denis and Schiff.) were examined. The experiments were carried out in randomized complete block design with 6 treatments in 4 replications. The insectiside treatments included spraying with: tebufenozide (Mimic® SC 20%) at the rates of 0.75 and 0.5L/ha, fipronil hexaflumuron (EC 5%) at the rate of 1 L/ha, emamectin benzoate (Emamectin® SG 5%) at the rate of 200 g/ha, indoxacarb (Avaunt® EC 15%) at the rate of 0.25 L/ha and the control treatment. The results in both Markazi and Kurdestan provinces based on the number of damaged plants and total production, show significant differences among the treatments at level of 1%. Tebufenozide (Mimic® SC20%, 0.75 L/ha) with 5.75±0.85 and 5.67±0.48 damaged plants and the yield equivalent of 401.525±8.25 and 415.65±9.07 kg/h respectively, was the most effective insecticide and Indoxacarb (Avaunt® EC15%) with 23.75 ± 2.86 and 24.25 ± 2.56 damaged plants and 279.15 ± 4.02 and 300.25 ± 3.89 kg/h a yield, respectively showed maximum loss and minimum product after the control. Therefore tebufenozide is recommended for the control of cutworms on chickpea.
