    Author(s): Zerhun Tomas Lera*

    Helicoverpa armigera is a major pest of chickpea in Ethiopia. Field experiment was conducted to verify the effectiveness of the Karant 5% EC (Emulsifiable Concentrate) insecticide against African bollworm (Helicoverpa armigera), (Hubner) (Lepidoptera: Noctuidae on chickpea were tested at Zala Shasha on trial site and Bossa Qacha on farmers’ field in a Randomized Complete Block Design (RCBD) with three replications during 2021. Percentage pod damage, mean larval count per plant, and grain yield were significantly affected by the treatments; two tested insecticides were significantly reduced the percentage pod damage and mean larvae per plant accordingly increased grain yield ha−1. The grain yield was highly affected by pod borer damage. The results revealed that the treatments with high pod borer damage had minimum grain yield (653.05 kg/ha); wh.. View more»
