Title: Field evaluation of newer insecticides for controlling pod fly (Melanagromyza obtusa) in pigeonpea (Cajanus cajan)
Abstract: A Held trial was carried out during rainy season of 1991-92 and 1992-93 to evaluate the efficacy of 4 new insecticides against pod fly (Melanagromyza obtusa Malloch) in 'Bahar' pigeonpea (Cajanus cajan Millsp.) in comparison to insecticidal application. The insecticidal efficacy was assessed on the basis of pod and grain damage as well as yield in different treatments. Results showed that carbosulfan @ 750 g a i/ha, benfuracarb @ 500 g a i/ha and etho fenprox @ 75 g a i/ha were highly effective in reducing pod (8.19-13.33%) and grain damage (4.33 - 12.33%) due to pod fly compared with the recommended monocrotophos application (18.00 - 22.31 % pod damage; 16.33 - 18.95% grain damage). These treatments also showed yields (l 367 - 2373 kg/ha) on par with monocrotophos (1 767 - 2 708 kg/ha) and were significantly superior to control (889 - 1 140 kg/ha).
